The competitive efficacy of the superficial musculoaponeurotic system (SMAS) rhytidectomy (SMASectomy) facelift has been well established. However, the outcomes after an associated open necklift have not been as reliable; the persistent incidence of recurrent bands and iatrogenic deformities has prompted a change in technique.
The author conducted a long-term retrospective review to evaluate a variation on the SMASectomy facelift technique. A solely lateral, "low SMAS" approach was substituted for direct necklift in all patients.
Patients who were candidates for a facelift underwent this laterally based, SMASectomy technique. Those who underwent concomitant full-face CO2 laser resurfacing were excluded from the review. A total of 198 patients treated consecutively during a 7-year period (2006-2012) were included in the study.
Postoperative follow-up ranged from 1 to 7 years. All patients' neck deformities were fully corrected by the solely lateral SMASectomy technique. In addition, the patients recovered more rapidly than with traditional direct necklift, with no nerve injuries, skin compromise, or hypertrophic scarring.
Results indicate that midline open necklift can be replaced by the low SMASectomy.
浅表肌肉腱膜系统（SMAS）除皱术（SMAS切除术）面部提升术的竞争效果已得到充分证实。然而，相关开放性颈部除皱术后的效果并不那么可靠；复发性条索和医源性畸形的持续发生率促使技术发生了改变。
作者进行了一项长期回顾性研究，以评估SMAS切除术面部提升技术的一种变体。在所有患者中，采用单纯外侧“低位SMAS”入路替代直接颈部除皱术。
适合面部提升的患者接受了这种基于外侧的SMAS切除术技术。那些同时接受全面部二氧化碳激光换肤的患者被排除在本研究之外。本研究纳入了2006年至2012年7年间连续治疗的198例患者。
术后随访时间为1至7年。所有患者的颈部畸形均通过单纯外侧SMAS切除术技术得到完全矫正。此外，患者恢复得比传统直接颈部除皱术更快，没有神经损伤、皮肤损伤或肥厚性瘢痕形成。
结果表明，中线开放性颈部除皱术可被低位SMAS切除术替代。
