ABSTRACT

Introduction: dentomaxillofacial deformities require a combined treatment of orthodontics and orthognathic surgery. Condylar remodeling and condylar displacement have been studied as possible side effects of the surgical procedure. With regard to the evaluation of the bony structures of the temporomandibular joint (TMJ), computed tomography is the test that offers the best results in identifying bone changes. Objective: to compare the pre and postoperative condylar position using Cone-Beam computed tomography in sagittal osteotomy of the bilateral mandibular branch in patients undergoing Orthognathic Surgery in the Maxillofacial Surgery Service of the "Dr. Domingo Luciani" Hospital in the period from January 2020 to October 2021. Material and methods: the research is comparative, longitudinal, retrospective. The population consisted of all patients who underwent orthognathic surgery and the sample consisted of patients who underwent orthognathic surgery and who underwent cone-beam tomography by the Bucomaxillofacial Surgery Service of the Hospital del Este "Dr. Domingo Luciani", in a period from January 2020 to October 2021. A matrix was designed to empty the study information in the Software: SPSS statistics in its spanish version No. 23. Results: there were no significant statistical results in the changes of the superior, anterior, medial, posterior joint space. An increase in the intercondylar distance was evidenced, which implies a lateral displacement of the condyle. Conclusions: prospective study of the morphological and structural changes of the condyle is the basis for improving the long-term prognosis of our patients.
