Abstract:
Abstract Objectives This study aimed to investigate the three-dimensional (3D) mandibular asymmetry in craniofacial microsomia (CFM) and its association with the Pruzansky–Kaban classification system. Materials and methods Cone-beam computed tomography images of 48 adult CFM cases were collected. The asymmetry of the mandibular body and ramus was analyzed with 3D landmarks. The mirrored mandibular model was registered on the original model, yielding a color-coded distance map and an average distance (i.e., asymmetry score) to quantify the overall mandibular asymmetry. Results The lengths of the mandibular body and ramus were significantly shorter on the affected than the contralateral side (p < 0.001). The ANB (p = 0.009), body and ramal lengths (both p < 0.001), and body and ramal length asymmetry (both p < 0.05) were significantly different between mild (types I/IIA) and severe (types IIB/III) cases. The mandibular asymmetry score correlated with mandibular body length asymmetry (r = 0.296, p = 0.046). CFM mandibles showed high variability in shape asymmetry. Conclusions CFM patients showed distinct body and ramal length asymmetries. In severe cases, mandibles were smaller, more retruded, and more asymmetric in length. The mandibular shape asymmetry was highly variable regardless of the Pruzansky–Kaban types, being a determinant in the extent of overall mandibular asymmetry. Clinical relevance The 3D morphologic analysis provides better insights into real mandibular asymmetry. Although the Pruzansky–Kaban classification was applied, high individual variability of the mandibular morphology still existed within the types. Therefore, individualized analyses and treatment plans for CFM patients are highly recommended.

Abstract:
Objective To determine whether asymmetric antigonial notching is associated with the development of mandibular and lower facial asymmetry in individuals with unilateral cleft lip and palate (UCLP). Design Retrospective mixed-longitudinal investigation including UCLP and nonaffected orthodontic patients. Participants All (24) available patients with UCLP treated in our clinic with complete longitudinal records, and 72 skeletal maturation matched noncleft orthodontic patients that served as controls. Subject records included hand-wrist, panoramic, frontal, and 45° oblique cephalometric radiographs. Main outcome Measures The development of mandibular asymmetry, measured on oblique cephalometric radiographs, as well as lower facial asymmetry, measured on frontal cephalometric radiographs, was monitored in individuals with UCLP in relation to antigonial notching asymmetry, assessed on panoramic and oblique cephalometric radiographs. Results First, no statistical differences were found in antigonial notching asymmetry between patients with UCLP and noncleft controls. Second, antigonial notching asymmetry, observed on panoramic and oblique cephalometric radiographs, significantly correlated with the attendant development of mandibular and lower facial asymmetry in individuals with UCLP. Third, the development of mandibular and lower facial asymmetry at pubertal and post-pubertal growth spurt stages significantly correlated with antigonial notching asymmetry, measured on panoramic radiographs, at prepubertal and pubertal growth spurt stages, respectively. Conclusions The degree of antigonial notching noted on panoramic radiographs can be used as an early indicator of developing mandibular and lower facial asymmetry in individuals with UCLP.

Abstract:
ABSTRACT Objectives: To investigate the treatment efficacy and follow-up stability of the asymmetric Forsus appliance by evaluating longitudinal changes in dental arch asymmetry on digital dental models from 21 patients. Materials and Methods: Maxillary and mandibular reference lines were used for measurements of intra-arch asymmetry at pretreatment (T1), posttreatment (T2), and 4.2 years after treatment (T3). Maxillary and mandibular measurements were performed relative to the dental midline and anterior reference line on digital dental models. To determine the amount of asymmetry between the Class I and Class II sides of a given arch, all maxillary and mandibular parameters were measured on each side of the model separately. Repeated-measures analysis of variance/paired sample t-tests were performed to evaluate dental arch asymmetries at the P < .05 level. Results: The alveolar transverse dimensions of the posterior segment of both arches were increased during treatment (P < .05) and remained stable during the retention period. Class II subdivision malocclusion was caused by distal positioning of the mandibular canine, premolars, and first molar on the Class II side (P < .05). Asymmetry was resolved by treatment with asymmetric Forsus appliances. The resolved asymmetry remained stable over the long term. There were no significant differences between T2 and T3 (P > .05). Conclusions: The asymmetric Forsus appliance can be used to treat dental arch asymmetry in patients with Class II subdivision malocclusions.

Abstract:
Objective: The purpose of this study was to retrospectively investigate mandibular asymmetry in unilateral cleft lip and palate individuals (UCLP) in relation to chronologic age and in relation to lower facial asymmetry. Design: The longitudinal records of 34 UCLP individuals and 142 controls treated in the Department of Orthodontics, Eastman Dental Center, Rochester, NY, were included in the study. Posteroanterior and oblique cephalometric radiographs were analyzed for lower facial asymmetry and mandibular asymmetry, respectively. Mandibular asymmetry in UCLP was analyzed relative to three age groups (6–10, 11–14, and 15 or greater) and compared to controls. Moreover, mandibular asymmetry was analyzed relative to lower facial asymmetry. Results: UCLP individuals showed no significant differences in mandibular asymmetry compared to controls. In addition, no significant correlation was found between mandibular asymmetry and lower facial asymmetry in UCLP. Conclusions: The degree of mandibular asymmetry in UCLP appears not to be the major contributing factor to the lower facial asymmetry noted on these individuals. Possible cranial-base/temporal-region anomalies may be involved in unilateral cleft lip and palate and be responsible of the asymmetry noted in the lower facial skeleton.

Abstract:
ABSTRACT Objectives: To estimate the prevalence of mandibular asymmetries in orthodontic and orthognathic surgery patients and to investigate demographic and skeletal factors associated with this disharmony. Materials and Methods: Cone-beam computed tomography images of 1178 individuals aged 19 through 60 years with complete dentitions were analyzed. Outcomes were classified as relative mandibular symmetry, moderate asymmetry, and severe asymmetry. Factors recorded included sex, age, side of mandibular deviation, sagittal jaw relationship, vertical skeletal pattern, angle of the cranial base, and maxillary asymmetry. Ordinal logistic regression was used to estimate simple and adjusted odds ratios (OR) for the individuals with moderate and severe mandibular asymmetry, as well as 95% confidence intervals. Results: Prevalence values of 55.2%, 27.2%, and 17.6% were observed for relative mandibular symmetry, moderate asymmetry, and severe asymmetry, respectively. An independent association with the side of mandibular deviation and the presence of maxillary asymmetry was observed, both for subjects with moderate mandibular asymmetry (left side: OR = 1.50; 95% CI: 1.01–2.24 / maxillary asymmetry: OR = 2.07; 95% CI: 1.11–3.76) and for those with severe asymmetry (left side: OR = 2.09; 95% CI: 1.27–3.44 / maxillary asymmetry: OR = 4.93; 95% CI: 2.64–9.20). Conclusions: Moderate and severe mandibular asymmetries were present in 44.8% of the sample, being associated with the side of mandibular deviation and with maxillary asymmetry.

Abstract:
Objective This study was conducted to evaluate the degree of maxillary and mandibular asymmetry in the verticle and transverse planes seen in posteroanterior cephalometric radiographs relative to chronologic age in postoperative complete UCLP patients compared to controls. Method Mandibular and nasomaxillary asymmetry was retrospectively studied in complete unilateral cleft lip and palate (UCLP) and noncleft individuals (controls) by means of posteroanterior cephalometric analysis. All the UCLP patients available (total 40) and randomly selected noncleft controls (total 142) were Included in the study. The UCLP patients had undergone lip and palate reconstruction in Strong Memorial Hospital, University of Rochester, Rochester, New York, and orthodontic treatment in the Department of Orthodontics, Eastman Dental Center, Rochester, New York. The controls were selected based on the age that treatment was initiated and were treated in the department for various malocclusions; none had undergone maxillary expansion or surgical treatment. The asymmetry assessed on mixed longitudinal records of the patients with UCLP was analyzed relative to three chronologic age groups and compared to the controls. In addition, mandibular asymmetry was correlated to maxillary asymmetry in UCLP individuals to investigate possible growth patterns between the two jaws. Results Mandibular asymmetry in UCLP individuals was found to increase with growth and time and peaked at post-pubertal growth-spurt stages. The cleft subjects were more asymmetric than controls in all stages of growth. Mandibular asymmetry followed the affected maxilla closely, indicating a parallel growth pattern of the jaws. Conclusion The unilateral cleft lip and palate patients manifested asymmetry of the mandible. This asymmetry develops in a parallel pattern with the affected maxilla, suggesting that early evaluation and treatment of the anomalies in the nasomaxillary skeleton as well as in the mandible is necessary when treating unilateral cleft lip and palate individuals.

Abstract:
It has been established that disk displacement of the temporomandibular joint(TMJ) can cause mandibular asymmetry in growing subjects. One of the causes of internal derangement of TMJ seems to be the result of poor positioning of the joint structure in unilateral cross bite, and the subsequent occlusal trauma transferred to the functioning unit of the mandible, the joint and disc. Transverse discrepancy of the maxillary and the mandibular posterior dentoalveolar units was often found in mandibular asymmetric subjects. Most of the asymmetry in growing subjects becomes worse with further growth if left untreated. However once sufficient posterior overjet is gained through orthodontic treatment, many cases have shown improvement in facial asymmetry. Furthermore, the position of condyles in computed tomogram(con-beam CT) changed from anatomically unfavorable position to more concentric position.

Abstract:
In patients with mandibular asymmetry, the volume of the mandible divided by the mandibular median plane is significantly larger on the non-deviated (N-Dev) side than on the deviated (Dev) side. However, it has been reported that there is no significant difference between the volumes of the N-Dev and Dev sides when the mandibular ramus and body are divided. The purpose of this study was to investigate which region is responsible for the volume difference between the N-Dev and Dev sides. Cone Beam Computed Tomography (CBCT) images of patients with mandibular asymmetry were analyzed by measuring the volume, and linear analysis of the mandibular body, ramus, and condyle on the N-Dev and Dev side was performed. In this study, CBCT images of 37 patients (8 Japanese, 16 Korean, and 13 Egyptian) aged ≥ 18 years with mandibular asymmetry (men: 20, women: 17) were used to evaluate mandibular asymmetry. In patients with mandibular asymmetry, the N-Dev side showed significantly larger values than the Dev side for both volume and linear condyle, ramus, and mandibular body measurements. These results do not differ according to sex or ethnicity. Therefore, it is suggested that the N-Dev side of mandibular asymmetry is large without any regional specificity in pathophysiology.

Abstract:
Background/Objectives: Facial asymmetry is known to cause not only deformities in the facial skeleton but also alterations in the cranial vault. However, limited research has explored the association between mandibular asymmetry and cranial vault deformation. This study aimed to evaluate the three-dimensional craniofacial morphology, including the cranial vault, in patients with skeletal mandibular prognathism using computed tomography (CT) imaging. Methods: Patients were classified into two groups: those with facial asymmetry (ANB ≤ 0°, Menton deviation ≥ 4 mm) and those without (ANB ≤ 0°, Menton deviation < 3 mm). Reference planes were established in three orthogonal directions, and distances from anatomical landmarks on the maxilla and mandible to each reference plane were measured. Additionally, the cranial vault was segmented into four regions, and the volume of each section was calculated. Results: Compared with the symmetric group, the asymmetric group exhibited significant lateral displacement in the maxilla and both anteroposterior and lateral displacements in the mandible. Furthermore, a significant difference in the posterior cranial vault volume between the left and right sides was observed in the asymmetric group. A moderate positive correlation (r = 0.543, p = 0.045) was also found between the direction of mandibular deviation and the direction of posterior cranial vault deformation. Conclusions: A moderate positive correlation (r = 0.543, p = 0.045) was observed between mandibular deviation and posterior cranial vault asymmetry. These findings may suggest that the cranial vault morphology may influence facial asymmetry, and it may serve as one of the considerations for discussing the necessity of early intervention for cranial vault deformity during infancy.

Abstract:
To evaluate and compare vertical mandibular asymmetry like condylar, ramal and condylar plus ramal mandibular vertical asymmetry using asymmetry indices among subjects with Angle’s class II subdivision malocclusion and subjects with Angle’s class I malocclusion from Orthopantomogram. Asymmetries in the lower third of the face are mainly due to mandibular asymmetries because of asymmetry in the height of condyle and ramus. As there is morphological variability in jaw bases in different malocclusion, it is anticipated that there will be variability in mandibular asymmetry. Considering this, it is decided to assess mandibular asymmetry in subjects with Angle’s class II subdivision and compare with subjects with Angle’s class I malocclusion. A total of 40 subjects coming to the department of orthodontics for fixed orthodontic treatment were equally divided into two groups i.e., Angle’s class II subdivision malocclusion group and Angle’s class I malocclusion group have selected (clinical examination) to assess type of malocclusion after screening of 80 subjects. Orthopantomogram of these subjects were taken before start of treatment and condylar height (CH), ramal height (RH), total height (RH) and mandibular asymmetry Index by Habet’s formula were evaluated. Data was obtained and subjected to statistical analysis. For group I and group II, CH (L>R), RH (R>L) and TH (L>R) but the difference was statistically significant only for condylar height of group II. Asymmetry indices did not show any significant difference between group I and group II. As mandibular asymmetry not show any significant difference between group I and group II hence it can be suggested that mandibular asymmetry in subjects with class II subdivision group was dentoalveolar in nature not skeletal.

Abstract:
Background: mandibular asymmetry poses a challenge in craniofacial diagnosis and treatment planning. Variability in etiology and presentations necessiates accurate assymetry diagnosis and quantification for treatment planning and follow-up. Conventional cephalometric radiographs have inherent superimpositions, magnifications and distortions, limiting their clinical value. Aims: To develop and trial novel diagnostic Cone Beam CT image analysis procedures, to enhance treatment by quanitification and localization of mandibular assymetries. Development and trials employed simulation and patient datasets, including end-user clinicians' perception of simulation versus conventional surgical outcomes. Methods: Twenty assymetric patients' CBCT volumes were segmented, constructing surface models, allowing 3D image analyses, using voxe3l-based co-registration. Mirroring techniques computed left to right side dissimilarities and validation studies initially compared known introduced assymetries. The SPHARM-PDM toolbox was then applied to a cohort of 60 patiens with varying degrees of assymetry to assess detection limits and functionality, including a Craniofacial Microsomia dataset. Finally, an algorith was developed to compute virtual mandibular surgical outcomes and a multi-centre study compared both real and virtual outcomes for 20 patients. Results: SPHARM-PDM proved a valid technology to quantify degree and direction of mandibular assymetries with probabilities of (0.99-1) and (0.84-1) respectively, that true assymetry was within 0.5 mm (translation) or 5 (rotations). Whether right or left mandible was mirrored, no statistical output differences were identified, demonstrating consistency. The functional limit is identified as no anatomical correspondence e.g. where a complete structural loss or external augmentation has arisen. Encouragingly, simulated outcomes based on virtual templates were better than actual outcomes, conventionally planned, in particular in difficult cases. Conclusion: SHARM-PDM is useful for diagnosis and quantification of mandibular assymetries and virtual templates in treatment planning offer potentials to increase predictability and optimize craniofacial interventions.

Abstract:
Un 1er travail a étudié les effets osseux mandibulaires de l’injection unilatérale dans les muscles masticateurs de toxine botulique (BTX) chez le rat adulte. Ceci entraine une perte osseuse mandibulaire condylienne et alvéolaire homolatérale importante. Une hypertrophie osseuse de l’enthèse d’insertion mandibulaire du muscle digastrique a été observée et pourrait correspondre à une étiologie pour les tori. Les effets de la BTX sur le cartilage articulaire condylien mandibulaire dans le même modèle animal ont été recherchés par analyse microtomographique du cartilage articulaire après augmentation de contraste à l’acétate d’uranyle. Aucune différence d’épaisseur cartilagineuse n’a été mise en évidence entre les groupes contrôles et BTX.Le 3ème travail a consisté en l’étude histologique et microtomographique des tori mandibulaires chez l’homme.Les tori sont différents des exostoses des os longs par plusieurs caractéristiques (dont l’absence de Fe et Al dans la matrice osseuse) et une asymétrie du remodelage osseux a été mise en évidence.La 4ème partie a consisté en l’étude de la qualité osseuse et de la microvascularisation alvéolaire dans un modèle animal d’ostéonécrose mandibulaire (ONM) aux bisphosphonates (BP). Des signes cliniques et microtomographiques d’ONM ont été observés dans la majorité des cas. La minéralisation osseuse était plus élevée après imprégnation en BP. La microvascularisation osseuse alvéolaire apparaissait augmentée après avulsion dentaire chez les animaux contrôles mais pas chez les animaux ayant reçu des BP témoignant ainsi d’un effet anti angiogénique in vivo des BP qui pourrait jouer un rôle dans la physiopathologie de l’ONM<br>First, bone changes at the mandible were studied after a unilateral botulinum toxin (BTX) injection in masticatory muscles in adult rats. A major alveolar and condylar bone loss was evidenced. The occurrence of a hypertrophic bone metaplasia at the digastric muscle enthesis was evidenced as well. This could constitute an etiological factor for tori. Then, condylar articular cartilage changes at the mandible were studied in the same BTX animal model, using microtomography after contrast enhancement of cartilage with uranyl acetate. Cartilage thickness measurement showed no difference when comparing control and BTX groups.A third work studied mandibular tori in human using histologic and microtomographic techniques. Tori appeared different from long bone exostoses by several characteristics (absence of Fe and Al in the bone matrix) and a specific asymmetric bone remodeling was evidenced.The fourth part consisted in the study of alveolar mandibular vascularization and quality of the bonematrix in an animal model of osteonecrosis of the jaws(ONJ) after bisphosphonates (BP) injections. Clinical and microtomographic signs of ONJ were found in mostof the cases. An increased mineralization of the alveolar bone was observed after BP impregnation. Microvascularization was increased after tooth extraction in the alveolar bone of control animals but it was impaired in ZA treated rats. Such an in vivo antiangiogenic effect of BPs could play a role in the pathophysiology of ONJ

Abstract:
A hiperplasia do côndilo mandibular é uma patologia complexa que causa sérias alterações na função oral e estética facial. É uma doença que frequentemente se apresenta na segunda ou terceira década de vida, resultante do crescimento vertical e/ou horizontal excessivo do côndilo mandibular. A classificação dos diferentes tipos de hiperplasia condilares pode diferir dependendo dos autores. Igualmente, diferentes critérios são utilizados para auxiliar no diagnóstico correto desta patologia que por sua vez é fundamental para determinar a terapêutica e o momento adequado do tratamento. Uma revisão narrativa foi realizada para analisar e discutir os diferentes protocolos de tratamento apresentados na literatura. A condilectomia (alta ou proporcional) pode ser usada como a terapêutica de tratamento e parece ser um procedimento seguro e eficaz, sem causar sequelas articulares funcionais. Essa técnica permite alcançar os principais objetivos do tratamento, que são eliminar o agente patogênico, impedir a progressão da doença e equalizar o ramo mandibular e a altura facial posterior. A literatura atual indica grandes variações quanto ao uso de diferentes exames de diagnóstico e tempo ideal desta intervenção. Assim, são necessários mais estudos para esclarecer quando a intervenção cirúrgica será mais eficaz e oportuna, e sobre qual será a quantidade de osso a excisar na operação.<br>Mandibular condyle hyperplasia is a disease that causes facial asymmetry as a result of excessive vertical or horizontal growth, or both, of the mandibular condyle. Classification of the different types of mandibular condyle hyperplasia can differ depending on the authors. Many diagnostic tools and criteria have been used to aid in the correct diagnosis of the unilateral condyle hyperplasia, which in turn is critical to determining the appropriate treatment and tim-ing. A narrative review of the literature was performed to analyze and discuss the different treatment protocols presented. The condylectomy (high or proportional) appear to be relevant surgical method and effective procedure, without functional joint sequelae, which prevents den-tal-facial deformity progression and helping future treatment. The current literature indicates large variations in terms of of diagnostic tools and preferred time of intervention. Thus, further studies are needed to clarify the optimum timing of intervention and the amount of bone that needs to be excised to prevent further growth.

Abstract:
Introdução: A estética facial é um fator preponderante no diagnóstico ortodôntico. No entanto, é difícil definir o objetivo do tratamento com base apenas no perfil estético, visto que não existe apenas um perfil facial considerado por toda a população como esteticamente atrativo, pois cada indivíduo tem o seu próprio conceito de beleza, que se relaciona com diversos fatores. Este estudo tem como objetivo a obtenção de dados específicos e atualizados, referentes à atratividade facial de indivíduos caucasianos de nacionalidade portuguesa. Pretende-se avaliar o impacto da proeminência mandibular, da assimetria facial, do perfil labial e da altura facial inferior, determinar o limiar em que se tornam clinicamente significativos e esteticamente relevantes e o impacto destas características por género e histórico de tratamento ortodôntico. Metodologia: Procedeu-se à manipulação de fotografias de um indivíduo do género masculino e um do género feminino, considerados esteticamente normais segundo os padrões correntes, alterando as características em estudo, com o intuito de criar um álbum com as fotografias organizadas aleatoriamente, que foi distribuído a 30 médicos dentistas, 30 estudantes de Medicina Dentária da UCP e 30 leigos, que avaliaram cada fotografia numa VAS de 100 mm. Resultados: Verificámos que o perfil facial escolhido como o mais atrativo foi o perfil padrão para ambos os géneros, sendo que a protrusão mandibular severa, a retrusão labial severa, a altura facial inferior diminuída extrema e a assimetria facial severa foram considerados como menos atrativos para ambos os géneros. Verificou-se que os leigos são menos críticos que os estudantes e profissionais de medicina dentária. Também se verificou a inexistência de diferença significativa da influência do histórico de tratamento ortodôntico e do género. Conclusões: A estética facial é um fator que interfere com a autoestima do paciente, acarretando implicações a vários níveis, sendo de grande interesse para o médico dentista comparar os critérios de avaliação da atratividade facial, permitindo uma melhor satisfação por parte do paciente, no que toca aos ideais do tratamento ortodôntico<br>Introduction: Facial aesthetics is an important factor for orthodontic diagnosis. However, it is difficult to define the goal of treatment only based on aesthetic profile, since there is not one only facial profile credited for the entire world population as aesthetically attractive, because each individual has his own concept of beauty, which is related to several factors. This study aims at obtaining specific and updated data, regarding facial attractiveness of Portuguese caucasians individuals. It is intended to assess the impact of mandibular prominence, facial asymmetry, lip profile and lower facial height, determine the threshold where they become clinically significant and aesthetically relevant to different groups, and the impact of these characteristics by gender and history of orthodontic treatment. Methods: We manipulate the photographs of a male and a female, aesthetically considered normal according to current standards, increasing and decreasing the features under study, with the aim of creating an album with randomly organized photos, which was distributed to 30 dentists, 30 dental students of UCP and 30 laypeople. Each one assessed each photograph in a 100 mm visual analog scale. Results: We found that the facial profile by the sample chosen as the most attractive was the straight profile for both genders, with severe mandibular protrusion, severe lip retrusion, severe lower facial height decreased and severe facial asymmetry were considered less attractive to both genders. It was found that the laypeople are less critical that students and dental professionals. It was also found that there was no significant difference in the influence of the history of orthodontic treatment and gender. Conclusions: The facial aesthetics is a factor that interferes with the patient's self-esteem, with implications at various levels, being of great interest to the dentist compare the evaluation criteria of facial attractiveness, in terms the satisfaction of the ideals of orthodontic treatment

Abstract:
Airway management in otherwise healthy children is normally easy in experienced hands and an unexpected difficult intubation should be uncommon. Predictors of difficult intubation include mandibular hypoplasia, limited mouth opening, facial asymmetry, and a history of stridor or obstructive sleep apnea. Many of these features occur in conditions such as Treacher Collins syndrome, Goldenhar's syndrome, and the Pierre Robin sequence.

Abstract:
The management of the difficult airway is one of the most challenging situations an anesthesiologist may encounter. The pediatric patient provides unique challenges such as lack of cooperation, rapid desaturation while apneic, and the presence of syndromes with craniofacial manifestations not frequently encountered in adults. These craniofacial manifestations may include mandibular hypoplasia, facial asymmetry, and limited mouth opening, to name a few. This chapter presents a case of a 5-year-old boy with Klippel-Feil syndrome and discusses the different aspects involved when dealing with a difficult airway in a pediatric patient, including the use of fiberoptic devices, neuromuscular blockade, and sedative premedication.

Abstract:
Orthognathic surgery restores the facial function and aesthetics affected by skeletal and dental deformities. A comprehensive preoperative evaluation, including cephalometric analysis, is essential to correcting facial skeletal imbalance and asymmetry. Operative planning must account for maxillary-to-mandibular occlusal relationship and dental compensations, as well as facial proportions in all dimensions. Virtual surgical planning has recently emerged as a way to facilitate more precise and accurate surgical planning. Operative techniques used to correct facial skeletal and dental deformities, broadly categorized as maxillary or mandibular excess or deficiency, include the LeFort I osteotomy, bilateral sagittal split osteotomy, and genioplasty.
