Treatment Protocol and Surgical Techniques for Macrogenia

Background: This study focused on the treatment protocol for macrogenia and surgical techniques of the semicircular ostectomy of the mandibular inferior border. Methods: Seven patients with macrogenia were treated following our treatment protocol including a preoperative assessment (the Delaire analysis), an operative design (three-dimensional reconstruction and simulation), operation techniques (semicircular ostectomy of the mandibular inferior border), and a postoperative evaluation. Results: Our treatment procedure provided an overall harmonizing effect on the lower facial contour. All 7 patients were satisfied with their aesthetic results. A few complications such as numbness and submental soft-tissue excess were observed, but they improved to different extent as time went by. Conclusions: Our treatment protocol for macrogenia is of great use to make the surgeries to be precisely and safely done with satisfactory results.
