To our knowledge, long-term, objective results of lip augmentation using superficial musculoaponeurotic system (SMAS) tissue transfer beyond 1 year have not been previously described.
To evaluate the efficacy, longevity, and safety of lip augmentation using SMAS tissue transfer.
DESIGN, SETTING, AND PARTICIPANTS: A retrospective single-blind cohort study was designed to evaluate all patients who underwent surgical lip augmentation using SMAS following rhytidectomy between January 1, 2000, and November, 16, 2015, at a private facial plastic surgery practice in Birmingham, Alabama. Preoperative photographs of each patient served as controls and were compared with postoperative photographs at 3 months, 1 year, and 5 years after lip augmentation. A total of 104 images (from 26 individual patients) were reviewed by 12 blinded observers using a validated lip augmentation grading scale.
Lip augmentation using SMAS.
Median lip volumes of all patients at each postoperative interval (3 months, 1 year, and 5 years) compared with preoperative lip volumes. Secondary outcome measures included postoperative complications.
A total of 423 patients were identified who underwent surgical lip augmentation using SMAS. Sixty patients with approximately 5 years or more of postoperative photographs were reviewed for complications. Twenty-six patients had 3-month, 1-year, and 5-year postoperative follow-up photographs and were included in the photographic evaluation. The mean age of these patients at the time of surgery was 54.6 years (range, 41.2-80.6 years. Fifty-nine of the 60 patients (98.3%) were female. Two of 60 patients (3.3%) with 5 years or more of postoperative follow-up developed complications requiring intervention. Both the superior lip and the inferior lip showed statistically significant increases in volume at 3 months, 1 year, and 5 years (P ≤ .004 for the superior lip after 5 years; P ≤ .001 for all other comparisons) after SMAS lip augmentation. The greatest median increase was observed in the superior lip at 3 months, while the smallest median increase was observed for the inferior lip at 5 years. The degree of increase in median volume seemed to weaken slightly over time, but remained statistically significant even at 5 years.
SMAS lip augmentation is an effective and safe method for lip augmentation that can yield natural, long-lasting results with minimal risk. The degree of augmentation tends to fade slightly over time, but remains significant for at least 5 years postoperatively.
据我们所知，此前尚未描述过使用表浅肌肉腱膜系统（SMAS）组织转移进行唇部填充超过1年的长期客观结果。
评估使用SMAS组织转移进行唇部填充的疗效、持久性和安全性。
设计、地点和参与者：一项回顾性单盲队列研究旨在评估2000年1月1日至2015年11月16日期间在阿拉巴马州伯明翰市一家私人面部整形手术诊所接受除皱术后使用SMAS进行手术唇部填充的所有患者。每位患者的术前照片作为对照，并与唇部填充后3个月、1年和5年的术后照片进行比较。12名盲法观察者使用经过验证的唇部填充分级量表对总共104张图像（来自26名个体患者）进行了评估。
使用SMAS进行唇部填充。
将所有患者在每个术后时间间隔（3个月、1年和5年）的唇部体积中位数与术前唇部体积进行比较。次要结局指标包括术后并发症。
共确定423例接受使用SMAS进行手术唇部填充的患者。对60例有术后约5年或更长时间照片的患者进行了并发症评估。26例患者有术后3个月、1年和5年的随访照片，并纳入了照片评估。这些患者手术时的平均年龄为54.6岁（范围41.2 - 80.6岁）。60例患者中有59例（98.3%）为女性。60例有5年或更长时间术后随访的患者中有2例（3.3%）出现需要干预的并发症。在使用SMAS进行唇部填充后，上唇和下唇在3个月、1年和5年时的体积均有统计学显著增加（5年后上唇P≤0.004；所有其他比较P≤0.001）。上唇在3个月时观察到最大的中位数增加，而下唇在5年时观察到最小的中位数增加。中位数体积增加程度似乎随时间略有减弱，但即使在5年时仍具有统计学显著性。
SMAS唇部填充是一种有效且安全的唇部填充方法，可产生自然、持久的效果且风险最小。填充程度往往会随时间略有消退，但术后至少5年仍很显著。
