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.
功能性颏成形术是一种下颌前部的截骨-切除术，可将过度的下前部面部高度降低至整个前部面部高度的55%。该手术尤其适用于导致长脸综合征的一个因素是下颌前部垂直过度的情况。手术技术包括制作榫头和榫眼，这不仅保留了唇颏肌和至少一些舌骨上肌的附着，还提高了经骨固定的稳定性。颏部和肌皮结构的向上重新定位和前移为患者带来了功能和美学上的益处。
