Many techniques have been presented over recent decades to address the neck contour in facial rejuvenation surgery. Despite advances, limitations remain when dealing with the obtuse cervical angle.
The authors describe a technique for improving the obtuse cervicomental angle.
The authors reviewed the charts of 295 patients who underwent the authors' submental muscular medialization and suspension (SMMS) technique to improve their neck contour, either alone or in combination with a facelift, between January 1, 2001, and December 30, 2003. The technique medializes and suspends the medial free edges of the platysma muscle and, when anatomy dictates, the anterior bellies of the digastric muscle to the deeper mylohyoid muscle.
Eighty-seven (30.5%) of the 285 facelift patients examined underwent SMMS, and 10 additional patients underwent isolated SMMS. No patient required reoperation for hemostasis or evacuation. Three (1.05%) of the facelift with SMMS patients required reoperation for dehiscence of the submental suspension. None of the isolated SMMS patients had muscular suspension dehiscence or required reoperation. Seven (2.4%) patients (5 with SMMS and 2 without SMMS) with excessive facial and cervical tissue preoperatively developed a small amount of postoperative submental skin redundancy and subsequently underwent submental skin excision at 1 year postoperatively.
Submental muscular medialization and suspension is a simple yet highly effective surgical technique that can result in dramatic and enduring improvement in the cervicomental angle.
近几十年来，已经提出了许多技术来解决面部年轻化手术中的颈部轮廓问题。尽管取得了进展，但在处理钝角颈椎角时仍然存在局限性。
作者描述了一种改善钝角颈颏角的技术。
作者回顾了 2001 年 1 月 1 日至 2003 年 12 月 30 日期间，295 例接受作者颏下肌内收和悬吊（SMMS）技术改善颈部轮廓的患者的图表，单独或与面部提升术联合应用。该技术将颈阔肌的内侧游离缘内收并悬吊，在解剖结构允许的情况下，将二腹肌前腹内收并悬吊至深层颏舌骨肌。
在检查的 285 例面部提升患者中，87 例（30.5%）接受了 SMMS，10 例单独接受了 SMMS。没有患者因止血或引流需要再次手术。3 例（1.05%）接受 SMMS 的面部提升患者因颏下悬吊处缝线裂开需要再次手术。没有单独接受 SMMS 的患者出现肌肉悬吊处缝线裂开或需要再次手术。7 例（2.4%）术前有过多面部和颈部组织的患者在术后出现少量颏下皮肤冗余，随后在术后 1 年接受了颏下皮肤切除术。
颏下肌内收和悬吊术是一种简单而非常有效的手术技术，可显著改善颈颏角，并持久改善。
