Correction of anterior mandibular vertical excess: the functional genioplasty. [Journal Article]
Oral Surg Oral Med Oral Pathol 1985 Mar; 59(3):229-35.
The functional genioplasty is an osteotomy-ostectomy of the anterior mandible which reduces excessive lower anterior facial height to 55% of the total anterior facial height. The procedure is indicated particularly when one factor contributing to the long-face syndrome is vertical excess of the anterior mandible. The surgical technique involves creation of a tenon and mortise which not only preserves the insertions of both the labiomental muscles and at least some of the suprahyoid muscles but also improves the stability of transosseous fixation. Superior repositioning and advancement of the chin and myocutaneous structures produce both functional and esthetic benefits for the patient.
