Assessment of Condylar Position Following Bilateral Sagittal Split Ramus Osteotomy Using Three-dimensional Computed Tomography

postoperative instabilities, surgical recurrence, and relapses. 7actors, including rotational movement of the distal segment, tensional balance of surrounding musculature, method of stabilization, and a surgeon's experience, are all known to alter postoperative condylar position.BSSO may alter condylar position, followed by initiation of the TMJ adaptation mechanism in both position and structure.These generated alterations in condylar position may impart physical tenacity on the condylar surface, resulting in TMJ condylar remodeling. 8,9Limited conebeam computed tomography (CBCT) evaluation studies and deficient evidence in the Indian population in this regard have therefore laid the foundation for this study. IntroductIonThe temporomandibular joint (TMJ) is a synovial and diarthrodial joint located between the articular eminence and glenoid fossa of the skull and mandibular condyle, also known as a ginglymoarthrodial joint. 1 The understanding of morphologic characteristics of TMJ is of utmost importance to the oral physician. 2To achieve a state of harmony throughout the entire stomatognathic system, it is important to establish proper functional and spatial relations within this joint system. 3Even the smallest imbalance leads to instability, often resulting in TMJ damage and degeneration.Additionally, it can exacerbate a variety of craniomandibular conditions. 4,5he clinical importance of condyle fossa connections is undisputed; however, the optimal position of the condyle into the glenoid fossa is still a conundrum.There is no quantitative standard known for it in the Indian population.However, the relative diameters of joint gaps between the glenoid fossa and mandibular condyle can be used to determine the condylar position.These joint gaps can be viewed radiographically in sagittal, axial, and coronal images, and various quantitative methods, such as subjective assessment, linear assessment, and protractor assessment, are used to locate the condylar position. 6rthognathic surgery holds importance in the treatment of skeletal dysplasia for both functionality and esthetics.Bilateral sagittal split osteotomy (BSSO) surgery is indispensable in many clinical scenarios requiring either augmentation or reduction.However, condylar movement postoperatively is important for the functional dynamics of TMJ and helps in preventing 1,
