Abstract

Strong mandibular angles and a heavy chin are perceived as masculine features, so surgical feminization of female or transgender faces may warrant mandibular base narrowing (borders and angles) and a reduction in chin width and height. With this in mind, we have devised an interdental midline osteotomy (triangular in shape and with a caudal base) to accompany a box-shaped impaction osteotomy of the chin symphysis and horizontal triangular resection of the lateral mandibular border. The reduction of the intergonial width and of the mandibular border and chin widths takes place upon closure of the midline defect. Between November 2016 and August 2017, five patients agreed to the mandibular feminization osteotomy and were followed up thereafter for 6–13 months. All expressed satisfaction with the results; no dental, periodontal, or temporomandibular joint-related complications were encountered. This technique is a viable alternative to buccal decortication, chin reduction osteotomy, and masseter reduction surgery.
