Minimally Invasive Sagittal Split Ramus Osteotomy

This randomized, double-blind, controlled, split-mouth clinical trial investigates the effects of two different surgical approaches - the conventional technique and a minimally invasive technique - during bilateral sagittal split ramus osteotomy (SSRO) for mandibular deformity correction. The study will be conducted at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Erciyes University. Each patient will receive both surgical techniques, randomly assigned to either side of the mandible. All procedures will be performed under general anesthesia by the same surgeon. Intraoperative outcomes including bleeding volume and operative time will be recorded. Postoperative evaluations will be conducted on day 1, weeks 1, 2, and 4, and at 3 months to assess pain and swelling. This study aims to determine whether the minimally invasive SSRO technique can improve surgical efficiency and reduce postoperative morbidity compared to the conventional approach, without compromising treatment outcomes.
