Lateral canthal tightening is indicated for patients undergoing lower eyelid blepharoplasty who have preexisting lower eyelid laxity or ectropion. A canthoplasty or canthopexy is indicated at the time of lower blepharoplasty to avoid postoperative complications, such as eyelid retraction or ectropion. Various surgical techniques are described to accomplish this goal, including canthopexy procedures, which usually access the lateral canthal tendon through an upper eyelid blepharoplasty or lateral canthal incision.
To describe an incisionless technique adjunctive to lower blepharoplasty, which stabilizes the lower eyelid in the week following blepharoplasty.
This operative technique description and retrospective case series includes 15 patients who underwent a simple incisionless temporary stabilization (SITS) during lower eyelid blepharoplasty. The procedures were performed at the same outpatient office-based surgery center and were performed by the author surgeons. Patients were followed from 3 to 6 months postoperatively.
The SITS procedure during lower eyelid blepharoplasty successfully maintained a desirable functional and aesthetic eyelid position with minimal complications. One patient reported tearing postoperatively which was determined to be unrelated to the SITS and resolved by the 1-month follow-up visit. No patient had any other complications during the follow-up period.
The SITS procedure was successfully utilized in patients with mild-to-moderate lower eyelid laxity and/or a negative vector to prevent postoperative ectropion and eyelid retraction. It is a more favorable alternative to temporary tarsorrhaphy, as it does not obstruct vision during healing and better secures the eyelid. It should not be used in patients with significant lower eyelid laxity that would place the patient at significant risk of ectropion and lower eyelid retraction related to swelling and inappropriate eyelid position during the early postoperative course.
对于存在下睑松弛或外翻的下睑成形术患者，需要进行外眦收紧。在进行下睑成形术时，需要进行眦成形术或眦固定术以避免术后并发症，如眼睑退缩或外翻。为实现这一目标，人们描述了多种手术技术，包括眦固定术，该技术通常通过上睑成形术或外眦切口进入外眦韧带。
描述一种辅助下睑成形术的无切口技术，该技术可在睑成形术后一周内稳定下睑。
本手术技术描述及回顾性病例系列包括15例在进行下睑成形术时接受简单无切口临时稳定术（SITS）的患者。手术在同一门诊手术中心进行，由作者外科医生实施。对患者进行术后3至6个月的随访。
下睑成形术中的SITS手术成功维持了理想的眼睑功能和美观位置，并发症极少。1例患者术后报告流泪，经确定与SITS无关，在1个月随访时症状消失。随访期间无其他患者出现任何并发症。
SITS手术成功应用于轻度至中度下睑松弛和/或负向量患者，以预防术后外翻和眼睑退缩。与临时睑缘缝合术相比，它是一种更有利的选择，因为它在愈合过程中不会妨碍视力，且能更好地固定眼睑。对于下睑严重松弛的患者，由于术后早期肿胀和眼睑位置不当会使患者面临外翻和下睑退缩的重大风险，因此不应使用该手术。
