PURPOSE: The aim of the present study was to report the experience of 40 patients who had undergone intraoral verticosagittal ramus osteotomy (IVSRO) to treat dentofacial deformities.
PATIENTS AND METHODS: The charts of 40 consecutive patients who had undergone IVSRO were analyzed regarding the diagnosis, amount of mandibular movement, and complications.
RESULTS: Eighty IVSROs were performed in 40 patients. The mean follow-up was 18 months. Mandibular protrusion in both genders was the main preoperative diagnosis (25 patients), and the treatment was 2-jaw surgery in 36 patients. The mean amount of movement was 2 mm for the mandible setback and advancement, 3 mm for mandible counterclockwise rotations, and 2 mm for mandible clockwise rotations. The mean period of maxillomandibular fixation was 15 days, followed by a period of heavy elastics. The rate of complications was 2%, including 2 bad splits, and 2 cases of intraoperative bleeding. No nerve injury was observed in the 40 patients studied.
CONCLUSIONS: The IVSRO is efficient and versatile, with low morbidity, and is an option for the oral and maxillofacial surgeon to treat patients with mandibular dentoskeletal discrepancies.
