Abstract:
Introduction: With a rise in gun violence across the United States, facial gunshot wounds (GSWs) present a challenging reconstructive problem that was once seldom encountered in civilian populations. Reconstruction of facial GSW injuries requires a combination of both microvascular and craniofacial surgical techniques. The aim of this study is to explore our experience with facial GSW injuries through an anatomic classification scheme and investigate the surgical techniques necessary to complete such reconstructions. Methods: A retrospective review was conducted at a tertiary academic center. All subjects who suffered facial GSWs and underwent definitive reconstruction at our institution were included. Facial GSWs were classified into 4 distinct anatomical zones of injury: lower (mandible), middle (maxilla and orbit), upper (above the orbit), and multi-zone injury. Microvascular reconstruction was further investigated based on the types of flaps used and the location of flap inset. Surgical outcomes, numbers of procedures, and complications were assessed, and statistical comparisons were made. Results: Thirty-six subjects underwent a total of 322 surgeries. Twenty subjects had multi-zone injury; 16 had single zone injury. Eighteen of the 36 subjects (50%) required microvascular reconstruction. These 18 subjects underwent a significantly increased number of reconstructive procedures ( P = .023). Twenty-six flaps were used, as multiple subjects required >1 flap. Fourteen of the 26 flaps were used in the middle third (54%), 7 in the lower third (27%), and 5 in the upper third (19%). Six flap complications required further surgical revision. On average, multi-zone injuries required more surgical procedures to complete reconstruction ( P = .018). Conclusion: Composite multi-zone facial GSW injuries present a higher degree of reconstructive complexity, and thus often require more surgical procedures, especially when the midface is involved. In our experience, microvascular reconstruction is more often used in multizone injury, and in our series was associated with an increased number of reconstructive procedures.

Abstract:
Aim and background A wide range of methodologies for breast reconstruction is now available. For immediate breast reconstruction we prefer to use implants, whereas reconstruction using autologous tissues, such as transverse rectus abdominis musculocutaneous flaps (TRAMF) and muscular latissimus dorsi flaps, is applied only in selected cases. In contrast, for delayed reconstruction the choice between prostheses and autologous tissue depends on various conditions. The different reconstructive methods can be adopted as a single procedure or as a combination of surgical procedures. Following the issue of legislation defining the new structure of the Italian Health Service, the need to accurately assess the costs incurred for the execution of surgical operations has taken on paramount importance. The aim of the study was to evaluate not only the clinical limits of each surgical technique, but also its cost, in order to optimize the choice of the same procedures, conditions being equal. Methods The study population included 105 patients who underwent breast reconstruction in the period 1st January 1994-30th June 1995. The reconstructive procedures included 48 immediate implants, 7 immediate TRAMF, 17 delayed implants, 30 delayed TRAMF, and 3 delayed latissimus dorsi muscular flaps. Results After data evaluation, we concluded that reconstruction using permanent expandable implants is the most convenient among implant reconstructions for its low global treatment cost. In fact, reconstructive procedures using temporary expanders, which require two surgical operations, have a higher cost than breast reconstruction using permanent expandable implants. Breast reconstruction using TRAMF is the most convenient because it limits the cost of surgical materials and because flap versatility limits the number of modifications on the contralateral breast. In contrast, breast reconstruction using latissimus dorsi flaps has high costs. Conclusions There is no balance between price list and effective cost of the different surgical reconstructive procedures, which may be a point of departure to see whether it is impossible to improve the efficiency of the Health Care System and in any case open a debate between the Regions and hospitals to improve the service, keeping it at a good level.

Abstract:
Poorly contoured mandibular reconstruction plates are associated with postoperative complications. Recently, a technique emerged whereby preoperative patient-specific reconstructive plates (PSRP) are developed in the hopes of eliminating errors in the plate-bending process. This study’s objective is to determine if reconstructions performed with PSRP are more accurate than manually contoured plates. Ten Otolaryngology residents each performed two ex vivo mandibular reconstructions, first using a PSRP followed by a manually contoured plate. Reconstruction time, CT scans, and accuracy measurements were collected. Paired Student’s t-test was performed. There was a significant difference between reconstructions with PSRP and manually contoured plates in: plate-mandible distance (0.39 ± 0.21 vs. 0.75 ± 0.31 mm, p = 0.0128), inter-fibular segment gap (0.90 ± 0.32 vs. 2.24 ± 1.03 mm, p = 0.0095), mandible-fibula gap (1.02 ± 0.39 vs. 2.87 ± 2.38 mm, p = 0.0260), average reconstruction deviation (1.11 ± 0.32 vs. 1.67 ± 0.47 mm, p = 0.0228), mandibular angle width difference (5.13 ± 4.32 vs. 11.79 ± 4.27 mm, p = 0.0221), and reconstruction time (16.67 ± 4.18 vs. 33.78 ± 8.45 min, p = 0.0006). Lower plate-mandible distance has been demonstrated to correlate with decreased plate extrusion rates. Similarly, improved bony apposition promotes bony union. PSRP appears to provide a more accurate scaffold to guide the surgeons in assembling donor bone segments, which could potentially improve patient outcome and reduce surgical time. Additionally, in-house PSRP can serve as a low-cost surgical simulation tool for resident education.

Abstract:
Background: Soft tissue sarcoma (STS) treatment is an interdisciplinary challenge. Along with radio(chemo)therapy, surgery plays the central role in STS treatment. Little is known about the impact of reconstructive surgery on STS, particularly whether reconstructive surgery enhances STS resection success with the usage of flaps. Here, we analyzed the 10-year experience at a university hospital’s Comprehensive Cancer Center, focusing on the role of reconstructive surgery. Methods: We performed a retrospective analysis of STS-patients over 10 years. We investigated patient demographics, diagnosis, surgical management, tissue/function reconstruction, complication rates, resection status, local recurrence and survival. Results: Analysis of 290 patients showed an association between clear surgical margin (R0) resections and higher-grade sarcoma in patients with free flaps. Major complications were lower with primary wound closure than with flaps. Comparison of reconstruction techniques showed no significant differences in complication rates. Wound healing was impaired in STS recurrence. The local recurrence risk was over two times higher with primary wound closure than with flaps. Conclusion: Defect reconstructions in STS are reliable and safe. Plastic surgeons should have a permanent place in interdisciplinary surgical STS treatment, with the full armamentarium of reconstruction methods.

Abstract:
Background: Around 100 to 200 patients undergo surgical reconstruction every year at our department of plastic and reconstructive surgery after Mohs micrographic surgery for nonmelanoma skin cancer. Objective: The aim of this report is to provide an overview of the type of facial reconstructions performed and investigate whether we achieved increased, definitive closure rates of the defect on the day of the excision after further improving the collaboration between the involved departments. Methods: All patients who underwent facial reconstruction at the Department of Plastic and Reconstructive Surgery following Mohs micrographic surgery between January 2006 and January 2011 were retrospectively systematically reviewed. Results: A total of 564 patients with 622 defects were identified. The different reconstructions used per aesthetic unit are described. The number of cases in which a reconstruction was performed on the same day as the resection significantly increased from 31 to 81% ( p < .001). Conclusion: Facial reconstruction following Mohs micrographic surgery is challenging. The type of reconstruction used depends on the type of defect and patient characteristics. A structured multidisciplinary approach improves the process from defect to reconstruction and can facilitate referrals.

Abstract:
Ten patients were treated with revision ankle ligament reconstruction from 1989 through 1994 for recurrent symptomatic instability of the ankle after failure of a primary reconstruction. There were seven female and three male patients with an average age of 28 years. In four patients, symptoms developed shortly after the first reconstruction and in six patients, symptoms developed 56.2 months (average) after the initial reconstruction surgery. The average follow-up was 14 months after revision surgery. All patients had significant functional impairment before surgery and all failed to respond to conservative treatment, which included physical therapy and bracing. Seven revision ligament reconstructions included the use of a tendon graft, including the pero-neus brevis, accessory peroneus, plantaris, and peroneus tertius. All revision procedures were modifications of the Elmslie procedure, (Sammarco-DiRaimondo). In addition, three Brostrom-Gould procedures were performed. The average follow-up was 31 months. All patients had clinical stability of the ankle following revision reconstruction. Nine patients (90%) returned to their previous functional level. After surgery, two patients had minimal pain and mononeuritis multiplex developed in one patient. The outcome of revision ankle ligament reconstruction compares favorably with reports for primary ankle reconstruction. Revision ankle reconstruction is a good procedure for selected patients. It is an appropriate option when conservative therapy fails to relieve recurrent symptoms of ankle instability following primary reconstruction.

Abstract:
Maxillofacial deformities resulting from the loss of tissue from the midfacial region may cause serious disfigurement. Modern facial plastic reconstructive techniques have been able to produce satisfactory results in the reconstruction of many of these facial deformities. There are specific indications where the use of a silastic prosthetic device may have a distinct advantage over a surgical reconstruction. Shortened hospitalization, early rehabilitation, decreased morbidity, and an excellent access to the surgical site for follow-up of cancer resection patients are important advantages when considering prosthetic rehabilitation. This technique does not supplant established surgical facial reconstructive methods, but offers a valuable adjunct for reconstruction of extensive lesions caused either by trauma or surgical resection.

Abstract:
Soft tissue reconstruction remains a clinical challenge for plastic surgeons. Currently flaps are the only reliable option but they are associated with a high morbidity. Adipose tissue engineering remains a promising alternative for soft tissue reconstruction. Cells, scaffolds and regulatory proteins form the basis of tissue engineering. This study investigated the use of two porous synthetic scaffolds: NovoSorb™ and Poly (ethylene Glycol) (PEG) to tissue engineer a subcutaneous adipose (fat) layer. Autologous fat graft (lipoaspirate) provided the cellular component and a decellularized matrix (Adipogel) was used as a source of adipogenic promoting proteins. Different combinations of the scaffolds with lipoaspirate and Adipogel were prepared in vitro and implanted into a rat using a back wound pocket model. These scaffolds were harvested at eight weeks. Histological and immunohistochemical staining was performed to assess the general morphology of the construct, formation of connective tissue, blood vessels and new adipose tissue in the scaffolds. The scaffolds allowed good vascularised connective tissue infiltration, although the formation of fat was limited. The study demonstrated that for adipose tissue formation a fine balance between inflammation and adipogenesis is required. Poly (ethylene Glycol) (PEG) allowed good infiltration of vascularised connective tissue. A two stage experiment was carried out to investigate if the scaffold could be used as a potential dermal substitute to support a skin graft as used clinically. PEG scaffolds were implanted in a wound pocket on a rodent’s back. After 2 weeks the skin overlying the scaffold was resected and a split skin graft was placed over the scaffold. A protective dressing was placed over the graft. The construct was harvested 10 days after the skin graft was placed over the scaffold in the wound. Macroscopic and histological assessments were performed to assess the percentage of graft take and integration of the scaffold and graft. The results showed the average graft take was greater than 70%. PEG scaffold supported a skin graft and can be used as a promising dermal substitute. An alternative approach to tissue engineering is the stimulation of adipose tissue growth directly by placement of a pedicled fat graft in vivo within a chamber. In the second arm of this project, a vascularised pedicled fat flap based on the epigastric artery and vein was transplanted into a polycarbonate chamber. Previous studies have shown that a foreign body reaction occurs in response to the chamber, which causes a fibrotic capsule to form around the flap. This capsule mechanically inhibits tissue growth of the flap. In this study, a chemical antifibrotic agent, Tranilast was used to reduce the fibrous capsule and investigate its effects on the volume of the fat flap. The experimental group was given Tranilast orally for seven days. The control group received an oral placebo drug. The flaps were harvested at 10 weeks. The volume of the fat flap and the thickness of the fibrous capsule around the fat flap were measured. The fibrous capsule in the Tranilast group was thinner when compared to the experimental group but it was not statistically different from the Control Group. There was no difference in flap volume in the two groups. In conclusion, NovoSorb and PEG porous scaffolds were able to support excellent host derived vascularization and connective tissue ingrowth, but the addition of an inductive matrix Adipogel to the scaffolds did not support increased adipogenesis. The addition of lipoaspirate to the scaffold pores marginally increased the degree of adipose tissue forming or surviving at 8 weeks. Both NovoSorb and PEG porous scaffolds have additional properties appropriate for skin reconstruction: NovoSorb induces neighboring host site adipose tissue to grow within its pores at the scaffold edges, and PEG is less inflammatory than NovoSorb and induces excellent collagen infiltration and is able to support the survival of a covering skin graft. Both scaffolds offer promise in skin reconstitution, but further advanced studies are required to promote adipose tissue formation within these scaffolds to tissue engineer the subcutaneous fat tissue layer.

The aim of this study was to determine the prevalence of nasal skin cancer, its location by facial aesthetic subunits and the type of reconstructive procedures performed for each nasal subunit after excision for nasal skin tumors. Observational cross-sectional study of all consecutive patients with the diagnosis of skin tumor located in the nasal unit, treated from 2018 to 2019 by the department of head and neck surgery of a general hospital. 60 patients were treated with nasal skin tumors excisions. A total of 52 patients (86,6%) had basal cell skin cancer, 7 (11,6%) had squamous cell skin cancer and 1 (1,6%) had melanoma. Fifty-nine patients (98.33%) presented a primary tumor and just 1 case (1,66%) recived a previous surgical treatment. Regardless of the type of tumor, the tip subunit was the most often involved with 29 (48,33%) cases in total. Despite of the nasal aesthetic subunit affected, the most frequent type of procedure used for reconstruction was the rotation or advancement flap, based on aesthetic nasal subunits, which was performed in 39 cases (65%). Nasal reconstruction after skin cancer can be very complex, especially since all patients have high expectations about the results. In order to achieve good results, there is a necessity for careful analysis of the defect, correct planning and excellent technical execution of the procedures Frequently, staged procedures will be needed to achieve an optimal result.

Abstract:
Virtual surgical planning (VSP) has the potential to make the work process of oral and maxillofacial surgery more efficient both in terms of performance and cost.  This study aims to investigate how VSP is used among oral and maxillofacial surgery clinics in Sweden, and to analyse VSP with regard to accuracy, healing, patient communication, and overall operative time.  A questionnaire was sent to all (n = 34) oral and maxillofacial surgery clinics in Sweden, concerning their knowledge and practice of VSP. A literature review was also carried out to compare the results from clinics in Sweden with the general view.  94 % of the oral and maxillofacial surgery clinics participated in the study, and all respondents affirmed knowledge of VSP. While 65 % recognise a need for VSP in their work, only 42 % utilise it. The main obstacles reported were economy, training, and availability. This was in high accordance with the literature review. The review also concluded that VSP increased accuracy, reduced planning time, decreased blood loss, and lowered the need for reoperations.  The presented study shows that VSP is beneficial both pre- and intra-operatively in orthognathic surgery, mandibular reconstruction and implant placement. Accuracy, planning, and patient communication are improved with VSP, both according to studies and questionnaire respondents. However, healing, overall operative time, and cost-benefit did not show strong evidence of improvement with VSP, which might explain the contrasted responses in the questionnaire on these subjects.

Abstract:
Le bloc opératoire est au coeur des soins délivrés dans l'hôpital. Suite à de nombreux développements techniques et médicaux, il devient équipé de salles opératoires hautement technologiques. Bien que ces changements soient bénéfiques pour le traitement des patients, ils accroissent la complexité du déroulement des opérations. Ils impliquent également la présence de nombreux systèmes électroniques fournissant de l'information sur les processus chirurgicaux. Ce travail s'intéresse au développement de méthodes statistiques permettant de modéliser le déroulement des processus chirurgicaux et d'en reconnaitre les étapes, en utilisant des signaux présents dans le bloc opératoire. Nous introduisons et formalisons le problème consistant à reconnaitre les phases réalisées au sein d'un processus chirurgical, en utilisant une représentation des chirurgies par une suite temporelle et multi-dimensionnelle de signaux synchronisés. Nous proposons ensuite des méthodes pour la modélisation, la segmentation hors-ligne et la reconnaissance en-ligne des phases chirurgicales. La méthode principale, une variante de modèle de Markov caché étendue par des variables de probabilités de phases, est démontrée sur deux applications médicales. La première concerne les interventions endoscopiques, la cholécystectomie étant prise en exemple. Les phases endoscopiques sont reconnues en utilisant des signaux indiquant l'utilisation des instruments et enregistrés lors de chirurgies réelles. La deuxième application concerne la reconnaissance des activités génériques d'une salle opératoire. Dans ce cas, la reconnaissance utilise de l'information 4D provenant d'un système de reconstruction multi-vues
The department of surgery is the core unit of the patient care system within a hospital. Due to continuous technical and medical developments, such departments are equipped with increasingly high-tech surgery rooms. This provides higher benefits for patient treatment, but also increases the complexity of the procedures' workflow. This also induces the presence of multiple electronic systems providing rich and various information about the surgical processes. The focus of this work is the development of statistical methods that permit the modeling and monitoring of surgical processes, based on signals available in the surgery room. We introduce and formalize the problem of recognizing phases within a workflow, using a representation of interventions in terms of multidimensional time-series formed by synchronized signals acquired over time. We then propose methods for the modeling, offline segmentation and on-line recognition of surgical phases. The main method, a variant of hidden Markov models augmented by phase probability variables, is demonstrated on two medical applications. The first one is the monitoring of endoscopic interventions, using cholecystectomy as illustrative surgery. Phases are recognized using signals indicating tool usage and recorded from real procedures. The second application is the monitoring of a generic surgery room workflow. In this case, phase recognition is performed by using 4D information from surgeries performed in a mock-up operating room in presence of a multi-view reconstruction system

Abstract:
Highly comminuted intra-articular fractures are complex and difficult injuries to treat. Once emergent care is rendered, the definitive treatment objective is to restore the original anatomy while minimizing surgically induced trauma. Operations that use limited or percutaneous approaches help preserve tissue vitality, but reduced visibility makes reconstruction more difficult. A pre-operative plan of how comminuted fragments would best be re-positioned to restore anatomy helps in executing a successful reduction. The objective of this work was to create new virtual fracture reconstruction technologies that would deliver that information for a clinical series of severe intra-articular fractures. As a step toward clinical application, algorithmic development benefits from the availability of more precise and controlled data. Therefore, this work first developed 3D puzzle solving methods in a surrogate platform not confounded by various in vivo complexities. Typical tibial plafond fracture fragmentation/dispersal patterns were generated with five identical replicas of human distal tibia anatomy that were machined from blocks of high-density polyetherurethane foam (bone fragmentation surrogate). Replicas were fractured using an instrumented drop tower and pre- and post-fracture geometries were obtained using laser scans and CT. A semi-automatic virtual reconstruction computer program aligned fragment native surfaces to a pre-fracture template. After effective reconstruction algorithms were created for the surrogate tibias, the next aim was to develop new algorithms that would accommodate confounding biologic factors and puzzle solve clinical fracture cases. First, a novel image analysis technique was developed to segment bone geometries from pre- and post-surgical reduction CT scans using a modified 3D watershed segmentation algorithm. Next, 3D puzzle solving algorithms were advanced to obtain fracture reconstructions in a series of highly comminuted tibial plafond fracture cases. Each tibia was methodically reconstructed by matching fragment native (periosteal and articular) surfaces to an intact template that was created from a mirror image of the healthy contralateral limb. Virtual reconstructions obtained for ten tibial plafond fracture cases had average alignment errors of 0.39±0.5 mm. These novel 3D puzzle solving methods are a significant advancement toward improving treatment by providing a powerful new tool for planning the surgical reconstruction of comminuted articular fractures.

Abstract:
This is an interdisciplinary research project in which the methods of Industrial and Product Design Engineering are focused upon a problem in Orthopaedics. One of the most controversial areas in Orthopaedics is the reconstruction of the anterior cruciate ligament (ACL). The current twin-instrument method for locating the ACL is difficult for surgeons with fewer than 500 surgical experiences. This was clearly demonstrated by Kohn, Busche and Cans (1995), and confirmed by Sommer, Friederich and Muller (2000), Sudhahar, Glasgow and Donell (2004), and Kuga, Yasuda, Hata et al. (2004). The above research indicates that the problem is not only one of anatomical location, but of how the operation takes place. The aim of the research was, therefore, to develop a new and improved surgical instrument and technique for locating the ACL anatomical landmarks. The research described in this thesis employs a number of design methods that can be used separately or in combination (hybrid process). They form the theory base that guides the design process. This allows the designer to engage in a flexible process that is effective in finding design solutions to the problem. Within this process, iterative case studies were employed in order to design a new surgical device for ACL reconstruction. The thesis describes a series of designed devices (case studies) that were iteratively developed and surgically tested, leading to a penultimate device. This latter device was tested via a number of surgical operations. The device provides a new method for externally locating the internal ACL attachment points. The research has resulted in a commercial association with Smith and Nephew Surgical Australia and BrainLAB AG Germany for the commercialisation of this technique. At the time of writing, the next stage of research and development is under way. This is using a frameless computer-aided image guidance system in the place of X-ray.

Abstract:
Medical image processing constitutes an important research area of the biomedical engineering since it provides accurate human body information for 3D visualization and analysis, diagnostic, surgical treatment planning, surgical training, prosthesis and implant design, wafer and surgical guides design. Computed tomography (CT) and magnetic resonance imaging (MRI) have had a great impact in the medicine since they can represent complex three dimensional (3D) anomalities or deformities. In this paper, the development of a system for tridimensional visualization and model reconstruction based on CT data is presented. The aim is to provide a system capable to assist the design process of prosthesis, implants and surgical guides by reconstructing anatomical 3D models which can be exported to any CAD program or computer aided surgery (CAS) system. A complete description of the proposed system is presented. The new system is able to visualize and reconstruct bone and/or soft tissues. Three types of renders are used: one for 3D visualization based on three planes, other for 3D surface reconstruction based on the well known marching cubes algorithm, and the other for 3D volume visualization based on the ray-casting algorithm. The functionality and performance of the system are evaluated by means of four case studies. The results have proved the capability of the system to visualize and reconstruct anatomical 3D models from medical images.

Abstract:
Objectives. This systematic review evaluates breast reconstruction options for women after mastectomy for breast cancer (or breast cancer prophylaxis). We addressed six Key Questions (KQs): (1) implant-based reconstruction (IBR) versus autologous reconstruction (AR), (2) timing of IBR and AR in relation to chemotherapy and radiation therapy, (3) comparisons of implant materials, (4) comparisons of anatomic planes for IBR, (5) use versus nonuse of human acellular dermal matrices (ADMs) during IBR, and (6) comparisons of AR flap types. Data sources and review methods. We searched Medline®, Embase®, Cochrane CENTRAL, CINAHL®, and ClinicalTrials.gov from inception to March 23, 2021, to identify comparative and single group studies. We extracted study data into the Systematic Review Data Repository Plus (SRDR+). We assessed the risk of bias and evaluated the strength of evidence (SoE) using standard methods. The protocol was registered in PROSPERO (registration number CRD42020193183). Results. We found 8 randomized controlled trials, 83 nonrandomized comparative studies, and 69 single group studies. Risk of bias was moderate to high for most studies. KQ1: Compared with IBR, AR is probably associated with clinically better patient satisfaction with breasts and sexual well-being but comparable general quality of life and psychosocial well-being (moderate SoE, all outcomes). AR probably poses a greater risk of deep vein thrombosis or pulmonary embolism (moderate SoE), but IBR probably poses a greater risk of reconstructive failure in the long term (1.5 to 4 years) (moderate SoE) and may pose a greater risk of breast seroma (low SoE). KQ 2: Conducting IBR either before or after radiation therapy may result in comparable physical well-being, psychosocial well-being, sexual well-being, and patient satisfaction with breasts (all low SoE), and probably results in comparable risks of implant failure/loss or need for explant surgery (moderate SoE). We found no evidence addressing timing of IBR or AR in relation to chemotherapy or timing of AR in relation to radiation therapy. KQ 3: Silicone and saline implants may result in clinically comparable patient satisfaction with breasts (low SoE). There is insufficient evidence regarding double lumen implants. KQ 4: Whether the implant is placed in the prepectoral or total submuscular plane may not be associated with risk of infections that are not explicitly implant related (low SoE). There is insufficient evidence addressing the comparisons between prepectoral and partial submuscular and between partial and total submuscular planes. KQ 5: The evidence is inconsistent regarding whether human ADM use during IBR impacts physical well-being, psychosocial well-being, or satisfaction with breasts. However, ADM use probably increases the risk of implant failure/loss or need for explant surgery (moderate SoE) and may increase the risk of infections not explicitly implant related (low SoE). Whether or not ADM is used probably is associated with comparable risks of seroma and unplanned repeat surgeries for revision (moderate SoE for both), and possibly necrosis (low SoE). KQ 6: AR with either transverse rectus abdominis (TRAM) or deep inferior epigastric perforator (DIEP) flaps may result in comparable patient satisfaction with breasts (low SoE), but TRAM flaps probably increase the risk of harms to the area of flap harvest (moderate SoE). AR with either DIEP or latissimus dorsi flaps may result in comparable patient satisfaction with breasts (low SoE), but there is insufficient evidence regarding thromboembolic events and no evidence regarding other surgical complications. Conclusion. Evidence regarding surgical breast reconstruction options is largely insufficient or of only low or moderate SoE. New high-quality research is needed, especially for timing of IBR and AR in relation to chemotherapy and radiation therapy, for comparisons of implant materials, and for comparisons of anatomic planes of implant placement.
