NASCIMENTO MEGER, Michelle et al. Surgical correction of vertical maxillary excess associated with mandibular self-rotation. RSBO (Online) [online]. 2017, vol.14, n.1, pp. 56-61. ISSN 1984-5685.

Introduction: The Class I skeletal deformity associated with vertical maxillary excess is a rare condition reported in the literature. Surgical impaction allows the correction of the long face and gummy smile. Objective: This case report aimed to evaluate the positioning of the condyle after Le Fort I osteotomy associated with mandibular selfrotation. Case report: The patient underwent orthognathic surgery for the correction of maxillary vertical excess. Tomography studies were performed to evaluate the initial and final position of the condyle. The patient improved mastication, breathing and phonetics, with esthetic benefit. Conclusion: After the Le Fort I osteotomy and mandibular self-rotation, the condyle remained stable occupying a new anterior-superior position in the glenoid fossa and patient's TMJ remained asymptomatic after 9 months of postoperative follow-up.
