Abstract:
Background Surgical management of the frontal sinus can be challenging. Extensive frontal sinus pneumatization may form a far lateral or supraorbital recess that can be difficult to reach by conventional endoscopic surgical techniques, requiring extended approaches such as the Draf III (or endoscopic modified Lothrop) procedure. Rigid endoscopes may not allow visualization of these lateral limits to ensure full evacuation of the disease process. Methods Here we describe the utility of intraoperative flexible endoscopy in two patients with far lateral frontal sinus disease. Results In both cases, flexible endoscopy allowed confirmation of complete evacuation of pathologic material, thereby obviating more extensive surgical dissection. Conclusion In cases where visualization of the far lateral frontal sinus is inadequate with rigid endoscopes, flexible endoscopy can be used to determine the need for more extensive dissection.

Abstract:
Background The utility of image guidance (image-guided surgery [IGS]) and intraoperative computed tomography (CT) scanning as a tool for less experienced endoscopic surgeons to aid in localization of paranasal sinus and skull base anatomic structures was evaluated. Methods Partial endoscopic dissection was performed on cadaver specimens by three fellowship trained rhinologists. Anatomic sites within and around the sinuses were tagged with radio-opaque markers. Otolaryngology residents identified tagged anatomic sites using four successive levels of technology: endoscopy alone (simulating outpatient clinic), endoscopy plus preoperative CT (simulating endoscopic sinus surgery [ESS] without IGS), endoscopy plus IGS registered to preoperative CT (simulating current ESS with IGS), and endoscopy plus IGS registered to real-time intraoperative CT. Responses were graded as follows: consensus rhinologist answer (4 points), close answer without clinically significant difference (3 points), within anatomic region but definite clinical difference (2 points), outside of anatomic region (1 point), no answer (0 points). Results Eleven residents participated. Of 20 specific anatomic sites, IGS-intraoperative CT provided the most accurate anatomic identification at 16 sites. For 8 sites, IGS-intraoperative CT had a significantly higher score than endoscopy alone (p < 0.05; eta2 = 0.29-0.67). For 6 sites, IGS-preoperative CT scan had a significantly higher score than endoscopy alone (p < 0.05; eta2 = 0.30-0.67). All participants found that IGS-intraoperative CT scan made them most comfortable in identifying anatomy. Conclusion Combined IGS and intraoperative CT scan technology may be an instructional adjunct for less experienced paranasal sinus surgeons for dissection and evaluation of unfamiliar or distorted anatomy.

Abstract:
OBJECTIVE: The aim of the present study was to evaluate the use of intraoperative otoendoscopy as a factor that could influence surgical decisionmaking in cholesteatoma surgery. MATERIALS AND METHODS: The material of this study included 82 ears with acquired cholesteatoma that were operated on. They were divided into 4 groups according to the surgical technique chosen and the use of the endoscope. Group I included 22 ears that underwent canal wall-down (CWD) tympanomastoid surgery, group II included 20 ears that underwent CWD tympanomastoid surgery with intraoperative use of endoscopy, group III included 20 ears that underwent canal wall-up (CWU) tympanomastoid surgery, and group IV included 20 ears that underwent CWU tympanomastoid surgery with intraoperative use of endoscopy. Endoscopy was used as a complementary tool to microscopy. The follow-up period ranged from 12 to 48 months. RESULTS: Intraoperative remnants of cholesteatoma matrix were detected during both CWU and CWD by the use of the rigid endoscope. However, its incidence was higher in the CWU group (50%) than in the CWD (30%) group. Most of these remnants were in the sinus tympani (37.5%). The mean duration of follow-up was 18.19 (±8.7) months. Postoperative residual cholesteatoma was much higher in the CWU group (25%) than in the CWD group (5%). All residuals were from groups of patients in whom intraoperative endoscopy was not used in the primary surgery. CONCLUSION: Our results showed that the use of the endoscope gave the surgeon better control over the pathology, thus achieving better eradication. Stated differently, the use of the endoscope raised the surgeon's confidence level about total removal and thus encouraged the surgeon to keep the canal wall intact while removing cholesteatoma in hidden areas. Therefore, the use of endoscope could be considered an additional tool that may affect decision-making in cholesteatoma surgery.

Abstract:
Object As demonstrated by histological and neuroimaging studies, pituitary adenomas have a capillary vascular density that differs significantly from that of surrounding structures. The authors hypothesized that intraoperative indocyanine green (ICG) fluorescence endoscopy could be used to visually differentiate tumor from surrounding tissues, including normal pituitary gland and dura. Methods After institutional review board approval, 16 patients undergoing endoscopic transsphenoidal surgery for benign pituitary lesions were prospectively enrolled in the study. A standard endoscopic endonasal approach to the sella was completed. Each patient then underwent endoscopic examination of the sellar dura and then the exposed pituitary adenoma after ICG bolus injection (12.5–25 mg). This examination was performed using a custom endoscope with a near-infrared light source and excitation wavelength filter. Results The authors successfully recorded ICG fluorescence from sellar dura, pituitary, and surrounding structures in 12 of 16 patients enrolled. There were 3 technical failures of intraoperative ICG endoscopy, and 1 patient was excluded following discovery of a dye cross-allergy. A standard dose of 25 mg of ICG in 10 ml of aqueous solution optimized visualization of sellar region microvasculature within 45 seconds of peripheral bolus injection. Adenoma was less fluorescent than normal pituitary gland. Dural invasion by tumor was identifiable by a marked increase in fluorescence compared with native dura. The ICG endoscopic examination added 15–20 minutes of operative time under general anesthesia. There were no complications that resulted from use of ICG or the fluorescent light source. Conclusions Indocyanine green fluorescence endoscopy shows promise as an intraoperative modality to visually distinguish pituitary tumors from normal tissue and to visually identify areas of dural invasion, thereby facilitating complete tumor resection and minimizing injury to surrounding structures. These results support the continued development of fluorescence endoscopic resection techniques.

Abstract:
OBJECTIVEThe goal of this study was to investigate the effectiveness and practicality of endoscopic surgery for treatment of supratentorial hypertensive intracerebral hemorrhage (HICH) compared with traditional craniotomy.METHODSThe authors retrospectively analyzed 151 consecutive patients who were operated on for treatment of supratentorial HICH between January 2009 and June 2014 in the Department of Neurosurgery at Chinese PLA General Hospital. Patients were separated into an endoscopy group (82 cases) and a craniotomy group (69 cases), depending on the surgery they received. The hematoma evacuation rate was calculated using 3D Slicer software to measure the hematoma volume. Comparisons of operative time, intraoperative blood loss, Glasgow Coma Scale score 1 week after surgery, hospitalization time, and modified Rankin Scale score 6 months after surgery were also made between these groups.RESULTSThere was no statistically significant difference in preoperative data between the endoscopy group and the craniotomy group (p > 0.05). The hematoma evacuation rate was 90.5% ± 6.5% in the endoscopy group and 82.3% ± 8.6% in the craniotomy group, which was statistically significant (p < 0.01). The operative time was 1.6 ± 0.7 hours in the endoscopy group and 5.2 ± 1.8 hours in the craniotomy group (p < 0.01). The intraoperative blood loss was 91.4 ± 93.1 ml in the endoscopy group and 605.6 ± 602.3 ml in the craniotomy group (p < 0.01). The 1-week postoperative Glasgow Coma Scale score was 11.5 ± 2.9 in the endoscopy group and 8.3 ± 3.8 in the craniotomy group (p < 0.01). The hospital stay was 11.6 ± 6.9 days in the endoscopy group and 13.2 ± 7.9 days in the craniotomy group (p < 0.05). The mean modified Rankin Scale score 6 months after surgery was 3.2 ± 1.5 in the endoscopy group and 4.1 ± 1.9 in the craniotomy group (p < 0.01). Patients had better recovery in the endoscopy group than in the craniotomy group. Data are expressed as the mean ± SD.CONCLUSIONSCompared with traditional craniotomy, endoscopic surgery was more effective, less invasive, and may have improved the prognoses of patients with supratentorial HICH. Endoscopic surgery is a promising method for treatment of supratentorial HICH. With the development of endoscope technology, endoscopic evacuation will become more widely used in the clinic. Prospective randomized controlled trials are needed.

Abstract:
Abstract BACKGROUND: Three-dimensional (3-D) endoscopy is a recent addition to augment the transsphenoidal surgical approach for anterior skull-base and parasellar lesions. We describe our experience implementing this technology into regular surgical practice. OBJECTIVE: Retrospective review of clinical factors and outcomes. METHODS: All patients were analyzed who had endoscopic endonasal parasellar operations since the introduction of the 3-D endoscope to our practice. Over an 18-month period, 160 operations were performed using solely endoscopic techniques. Sixty-five of these were with the Visionsense VSII 3-D endoscope and 95 utilized 2-dimensional (2-D) high-definition (HD) Storz endoscopes. Intraoperative and postoperative findings were analyzed in a retrospective fashion. RESULTS: Comparing both groups, there was no significant difference in total or surgical operating room times comparing the 2-D HD and 3-D endoscopes (239 minutes vs 229 minutes, P = .47). Within disease-specific comparison, pituitary adenoma resection was significantly shorter utilizing the 3-D endoscope (surgical time 174 minutes vs 147 minutes, P = .03). These findings were independent of resident or fellow experience. There was no significant difference in the rate of complication, reoperation, tumor resection, or intraoperative cerebrospinal fluid leaks. Subjectively, the 3-D endoscope offered increased agility with 3-D techniques such as exposing the sphenoid rostrum, drilling sphenoidal septations, and identifying bony landmarks and suprasellar structures. CONCLUSION: The 3-D endoscope is a useful alternative to the 2-D HD endoscope for transnasal anterior skull-base surgery. Preliminary results suggest it is more efficient surgically and has a shorter learning curve. As 3-D technology and resolution improve, it should serve to be an invaluable tool for neuroendoscopy.

Abstract:
Intraoperative distinction of pituitary adenoma from normal gland is critical in maximizing tumor resection without compromising pituitary function. Contact endoscopy provides a noninvasive technique that allows for real-time in vivo visualization of differences in tissue vascularity. Two illustrative cases of endoscopic endonasal approaches (EEAs) for resection of pituitary adenoma illustrate the use of contact endoscopy in identifying tumor from gland and differentiating a thin section of normal gland draped over the underlying tumor, thereby allowing for safe extracapsular tumor resection. Contact endoscopy may be used as an adjunct for intraoperative, in vivo differentiation of pituitary gland and adenoma.

Abstract:
Background: Seizures, neurological deficits, bradycardia, and, in the worst cases, cardiac arrest may occur following incidental durotomy during routine lumbar endoscopy. Therefore, we set out to measure the intraoperative epidural pressure during lumbar endoscopic decompression surgery. Methods: We conducted a retrospective observational cohort study to obtain intraoperative epidural measurements with an epidural catheter-pressure transducer assembly through the spinal endoscope on 15 patients who underwent lumbar endoscopic decompression of symptomatic lumbar herniated discs and spinal stenosis. The endoscopic interlaminar technique was employed. Results: There were six (40.0%) female and nine (60.0%) male patients aged 49.0667 ± 11.31034, ranging from 36 to 72 years, with an average follow-up of 35.15 ± 12.48 months. Three of the fifteen patients had seizures with durotomy and one of these three had intracranial air on their postoperative brain CT. Another patient developed spinal headaches and diplopia on postoperative day one when her deteriorating neurological function was investigated with a brain computed tomography (CT) scan, showing an intraventricular hemorrhage consistent with a Fisher Grade IV subarachnoid hemorrhage. A CT angiogram did not show any abnormalities. Pressure recordings in the epidural space in nine patients ranged from 20 to 29 mm Hg with a mean of 24.33 mm Hg. Conclusion: Most incidental durotomies encountered during lumbar interlaminar endoscopy can be managed without formal repair and supportive care measures. The intradural spread of irrigation fluid and intraoperatively used drugs and air entrapment through an unrecognized durotomy should be suspected if patients deteriorate in the recovery room. Ascending paralysis may cause nausea, vomiting, upper and lower motor neuron symptoms, cranial nerve palsies, hypotension, bradycardia, and respiratory and cardiac arrest. The recovery team should be prepared to manage these complications.

Abstract:
A introdução dos endoscópios na otorrinolaringologia determinou um grande avanço tecnológico, permitindo a sistematização da cirurgia endoscópica nasossinusal funcional. A possibilidade de trabalhar nos limites das cavidades nasossinusais com boa iluminação e visibilidade permitiu a expansão dessa cirurgia para abordar lesões da base do crânio e no interior da cavidade craniana, ampliando consideravelmente as suas indicações e a gravidade das suas complicações. Dentre estas complicações as lesões vasculares e ou de nervos cranianos estão entre as principais causas de morbidade. A artéria frontobasilar medial (AFM) é o primeiro ramo cortical do segmento pós-comunicante da artéria cerebral anterior e possui percurso próximo a base anterior do crânio. Havendo penetração intracraniana através da base anterior do crânio, durante uma cirurgia endoscópica endonasal, a AFM pode ser lesionada causando graves complicações. O objetivo deste estudo foi analisar as relações da AFM com a base anterior do crânio e reparos anatômicos utilizados em cirurgia endonasal, através de imagens obtidas por angiotomografia de crânio. E também identificar os locais de maior proximidade da AFM com a base anterior do crânio, sugerindo áreas de maior risco de lesão em cirurgia endonasal. Foram analisados 52 exames de angiotomografia de crânio, realizados no período de 2013 a 2015. O software OsiriXÒ foi utilizado para fazer as medições entre a AFM e os pontos de referência nos planos sagital e coronal, na ordem cronológica em que os exames foram coletados. A AFM descreveu um trajeto descendente, próximo a linha média (distancia média de 1,5 mm), se aproximando do plano esfenoidal (distancia média de 1,8 mm) e depois um trajeto ascendente à medida que se dirige para porção anterior do crânio, com distância média de 4,4mm na região da parede anterior do seio esfenoidal e de 12mm na região onde se encontra a artéria etmoidal anterior. Considerando o ângulo de trabalho na cirurgia endonasal e a os locais de maior proximidade da AFM com a base anterior do crânio, as regiões do etmoide posterior e plano esfenoidal foram as áreas de maior risco de sua lesão Study of the relations between medial orbitofrontal artery and anterior skull base performed by computed tomography angiography<br>The introduction of endoscopes in otolaryngology determined a great technological advance, allowing the systematization of the endoscopic endonasal sinus surgery. The possibility of working at the nasal cavity boundaries with good illumination and visibility allowed the expansion of this surgery to address lesions of the skull base and inside the cranial cavity, considerably broadening its indications and the severity of its complications. Among these complications, vascular lesions and cranial nerves are among the main causes of morbidity. The medial orbitofrontal artery (MOFA) the first cortical branch of the post-communicating segment of the anterior cerebral artery and has a path near the anterior skull base. If there is an intracranial penetration through the anterior skull base, during endonasal surgery, the MOFA can be injured causing serious complications. The objective of this study was to analyze the MOFA relations with the anterior skull base and anatomical repairs used in endonasal surgery, through images obtained by computed tomography angiography. And also identify the sites of greater proximity of the MOFA with the anterior skull base, suggesting areas of greater risk of injury in endonasal surgery. It was studied 52 examinations of skull computed tomography angiography performed between 2013 and 2015. The OsiriXÒ software was used to make the measurements between the MOFA and the reference points in the sagittal and coronal planes, in the chronological order in which the exams were collected. The MOFA described a descending path, close to the midline (average distance of 1.5 mm), approaching the sphenoid plane (average distance of 1.8 mm) and then an ascending path as it is directed towards the anterior portion of the skull, with an average distance of 4.4 mm in the region of the anterior wall of the sphenoid sinus and 12 mm in the region where the anterior ethmoid artery is located. Considering the angle of work in endonasal surgery and the places of greater proximity of the MOFA with the anterior skull base, the regions of the posterior ethmoid and sphenoid plane were the areas of greatest risk of its lesion

Abstract:
Il manque actuellement aux médecins une nouvelle méthode qui rationalise le traitement peu invasif pour en faire des procédures à opérateur unique, assistées par une caractérisation précise des tissus in situ et en temps réel, en situation de prise de décisions dans la gestion du cancer colorectal. Une solution prometteuse à ce problème a été développée par l'équipe AVR (Automatique, Vision et Robotique) du laboratoire ICube, au sein de laquelle l'endoscope interventionnel flexible (fabriqué par Karl Storz) a été entièrement robotisé, permettant ainsi à un seul opérateur de télémanipuler indépendamment l'endoscope et deux instruments thérapeutiques insérables, grâce à unité de contrôle commune. Cependant, l'endoscope flexible assisté par robot est soumis aux mêmes limites de précision diagnostique que les systèmes d'endoscopie standards. Il a été démontré que l'OCT endoscopique présente un potentiel pour l'imagerie des troubles de la voie gastro-intestinale et pour la différenciation de tissus sains des tissus malades. Actuellement, l'OCT se limite à l'imagerie de l'œsophage humain, qui présente une géométrie simple et un accès facile. Ni l'OCT, ni l'endoscope robotisé ne peuvent résoudre à eux seuls les limites de la norme actuelle de soins pour la prise en charge d’un cancer du côlon. La combinaison de ces deux technologies et le développement d'une nouvelle plate-forme pour la détection et le traitement précoce du cancer constituent l'objet principal de cette thèse, avec la vision de développer une console d'imagerie OCT et une sonde de haute technologie intégrée à l'endoscope robotisé. Ce système permet d'obtenir des images de l'intérieur du gros intestin pour la caractérisation des tissus et l'assistance au traitement, permettant ainsi à un seul opérateur d'effectuer une intervention peu invasive en mode télémanipulation<br>There exists an unmet clinical need to provide doctors with a new method that streamlines minimally invasive endoscopic treatment of colorectal cancer to single operator procedures assisted by in-situ and real-time accurate tissue characterization for informed treatment decisions. A promising solution to this problem has been developed at the ICube laboratory, in which the flexible interventional endoscope (Karl Storz) was completely robotized, so allowing a single operator to independently telemanipulate the endoscope and two insertable therapeutic instruments with a joint control unit. However, the robot-assisted flexible endoscope is subject to the same diagnostic accuracy limitations as standard endoscopy systems. It has been demonstrated that endoscopic optical coherence tomography (OCT) has a good potential for imaging disorders in the gastrointestinal tract and differentiating healthy tissue from diseased. Neither OCT, nor the robotized endoscope can solve the limitations of current standard of care for colon cancer management alone. Combining these two technologies and developing a new platform for early detection and treatment of cancer is the main interest of this work, with the aim of developing a state-of-the-art OCT imaging console and probe integrated with the robotized endoscope. The capabilities of this new technology for imaging of the interior of the large intestine were tested in pre-clinical experiments showing potential for improvement in margin verification during minimally invasive endoscopic treatment in the telemanipulation mode

Abstract:
Au cours des dernières décennies, la chirurgie mini invasive a progressivement gagné en popularité face à la chirurgie ouverte, grâce à de meilleurs bénéfices cliniques. Cependant, ce type d'intervention introduit une perte de vision directe sur la scène pour le chirurgien. L'introduction de la réalité augmentée en chirurgie mini invasive semble être une solution viable afin de remédier à ce problème et a donc été activement considérée par la recherche. Néanmoins, augmenter correctement une scène laparoscopique reste difficile à cause de la non-rigidité des tissus et organes abdominaux. En conséquence, la littérature ne fournit pas d'approche satisfaisante à la réalité augmentée en laparoscopie, car de telles méthodes manquent de précision ou requièrent un équipement supplémentaire, contraignant et onéreux. Dans ce contexte, nous présentons un nouveau paradigme à la réalité augmentée en chirurgie laparoscopique. Se reposant uniquement sur l'équipement standard d'une salle opératoire hybride, notre approche peut fournir la relation statique entre l'endoscope et un scan intraopératoire 3D. De nombreuses expériences sur un motif radio-opaque montrent quantitativement que nos augmentations sont exactes à moins d'un millimètre près. Des tests sur des données in vivo consolident la démonstration du potentiel clinique de notre approche dans plusieurs cas chirurgicaux réalistes<br>Over the past decades, minimally invasive surgery has progressively become more popular than open surgery thanks to greater clinical benefits. However, this kind of intervention introduced a loss of direct vision upon the scene for the surgeon. Introducing augmented reality to minimally invasive surgery appears to be a viable solution to alleviate this drawback and has thus been an attractive topic for the research community. Yet, correctly augmenting a laparoscopic scene remains challenging, due to the non-rigidity of abdominal tissues and organs. Therefore, the literature does not report a satisfactory approach to laparoscopic augmented reality, as such methods lack accuracy or require expensive and impractical additional equipment. In light of this, we present a novel paradigm to augmented reality in abdominal minimally invasive surgery. Based only on standard hybrid operating room equipment, our approach can provide the static relationship between the endoscope and an intraoperative 3D scan. Extensive experiments on a radio-opaque pattern quantitatively show that the accuracy of our augmentations is less than one millimeter. Tests on in vivo data further demonstrates the clinical potential of our approach in several realistic surgical cases

Abstract:
This chapter on laryngotracheal reconstruction (LTR) describes and reviews the preoperative, intraoperative, and postoperative course of a virtual case of a patient undergoing double stage laryngotracheal reconstruction (ds-LTR). The discussion section reviews the etiology and pathogenesis of subglottic stenosis (SGS) and describes the Myer-Cotton classification system of SGS. The chapter also reviews the medical management of gastroesophageal reflux disease, endoscopic treatment of granulations, anterior cricoid split, LTR with cartilage augmentation (single and double stage), and cricotracheal resection. The differences in the technique and patient selection of single stage LTR (ss-LTR) and ds-LTR are reviewed. The intraoperative and postoperative complications of LTR and postoperative sedation management are also discussed.

Abstract:
Surgery is one of the most prevalent methods of control- ling and eradicating tumor growth in the human body, with a projection of 45 million surgical procedures per year by 2030 [1]. In brain tumor resection surgeries, pre- operative images used for the detection and localization of the cancer regions become less reliable throughout surgery when used intraoperatively due to the brain moving during the procedure, referred to as brain shift. To solve the brain shift problem, intraoperative MRI (iMRI) has been used, but it is costly, time intensive, and only available at the most advanced care facilities [2]. Intraoperative fluorescence-guided methods, both exoge- nous (introducing foreign fluorophore molecules into the body) and endogenous (utilizing innate fluorophores within the body), have been investigated as an alternative to iMRI to circumvent the brain shift problem. This paper introduces the proposed design, shown in Fig. 1(a), of an endoscopic tool for intraoperative brain tumor detection incorporating a laser-based endogenous fluorescence method previously explored by [3], called TumorID, depicted in Fig. 1(b). The device has also been deployed on ex-vivo pituitary adenoma tissue by [4] for intraoperative pituitary adenoma identification and subtype classification. This study explores whether a non-perpendicular angle of incidence (AoI) will sig- nificantly affect the emitted spectral data. With a better understanding of the relationship between AoI and col- lected spectra, the results can help shed light on the potential steering modality ( optical [5] or fiber [6]) and end-effector movement profile for the proposed optics- based endoscopic tool.

Abstract:
Objective: Investigate the impact of diaphragm sellae competence on surgical outcomes and risk factors for postoperative hypothalamic injury (HI) in patients undergoing endoscopic transsphenoidal surgery (ETS) for infra-diaphragmatic craniopharyngiomas (ICs). Methods: A retrospective analysis of 54 consecutive patients (2016-2023) with ICs treated by ETS was conducted. All tumors originated from the sellar region inferior to the diaphragm sellae and were classified into two subtypes in terms of diaphragm sellae competence: IC with competent diaphragm sellae (IC-CDS) and IC with incompetent diaphragm sellae (IC-IDS). Clinical features, intraoperative findings, and follow-up data were compared between subtypes. Postoperative HI was assessed using a magnetic resonance imaging-based scoring system. Results: Fifty-four patients (29 males, 25 females) were included in this study, with 12 (22.2%) under 18 years old. Overall, 35 cases were IC-CDS, while 19 were IC-IDS. Compared with IC-CDS, patients with IC-IDS tended to have hormone hypofunction before surgery (p = 0.03). Tumor volume in IC-IDS group (9.0 ± 8.6 cm3) was also higher than that in IC-CDS group (3.3 ±3.4 cm, p = 0.011). Thirty-seven patients underwent standard endoscopic transsphenoidal approach (SEA) and 17 underwent an extended endoscopic transsphenoidal approach (EEA). Gross total resection (GTR) was achieved in 50 cases (92.6%). Postoperative CSF leak was observed in four patients (7.4%). Permanent diabetes insipidus (DI) occurred in 13 patients (27.7%), six in IC-CDS and seven in IC-IDS. Postoperative HI occurred in 38.9% of patients. Univariate analysis revealed that large tumor size (p = 0.014), prior hypopituitarism (p = 0.048) and IC-IDS (p &lt; 0.001) were significantly associated with postoperative HI. Multivariate analysis revealed that IC- IDS was the sole predictor of postoperative HI. Conclusion: To our knowledge, this is the largest case series in the literature to describe IC resected by endoscopic surgery in a single institution. Classification based on diaphragm sellae competence highlights distinct clinical features and surgical outcomes between IC-CDS and IC-IDS subtypes. Notably, IC-IDS is an independent risk factor for postoperative HI. Preoperative identification of subtype can guide surgical strategy and potentially minimize complications.
