The correction of jaw deformities usually requires orthognathic surgery, aimed at achieving good function and favorable esthetic aesthetic results. This study aimed to report on the efficacy of clockwise rotation of the maxillomandibular complex for correcting a protruding chin in skeletal class III malformations with a brachyfacial profile and positive overjet, using bimaxillary surgery. Two patients underwent clockwise rotation of the maxillomandibular complex through a surgical procedure consisting of a Le Fort I maxillary osteotomy and bilateral sagittal split ramus osteotomy (BSSO). The first patient was a 29-year-old male who received this orthognathic surgery without prior orthodontic treatment. Two L-shaped absorbent plates were used for Le Fort I osteotomy fixation, and titanium wires were used for BSSO loose fixation. The second patient was a 23-year-old female who underwent preoperative orthodontic treatment followed by orthognathic surgery and postoperative orthodontic treatment. Two L-shaped titanium plates were used for Le Fort I osteotomy fixation, and two I-shaped titanium plates were used for BSSO fixation. Additionally, the patient underwent bilateral mandibular angle osteotomies to reduce the prominent angle. Clockwise rotation of the maxillomandibular complex provided satisfying facial esthetic results, with a mesofacial profile and normal chin.
