Rectus muscle plication is an alternative muscle-strengthening procedure to rectus muscle resection. Possible advantages of rectus muscle plication include a lower risk of "lost" muscles and anterior segment ischemia.
This was a retrospective case series describing a surgical procedure for rectus muscle plication using an adjustable suture technique that can be used on any of the four rectus muscles.
A total of 5 adult patients underwent adjustable suture plication procedures. Of these, 2 patients required suture adjustment postoperatively. At the final follow-up visit, all the patients maintained satisfactory ocular alignment within 6(Δ) of orthotropia for horizontal deviations and 2(Δ) of orthotropia for vertical deviations. Diplopia was eliminated in all cases with preoperative diplopia. There were no postoperative complications or unexpected shifts in ocular alignment.
Rectus muscle plication using this adjustable suture technique may serve as an alternative to rectus muscle resection and may be particularly useful in patients who are at risk for anterior segment ischemia or those in whom a shorter anesthesia time is recommended.
直肌折叠术是直肌切除术之外的另一种增强肌肉的手术方法。直肌折叠术的潜在优势包括“丢失”肌肉和眼前节缺血的风险较低。
这是一项回顾性病例系列研究，描述了一种使用可调节缝线技术的直肌折叠手术方法，该技术可用于四条直肌中的任何一条。
共有5例成年患者接受了可调节缝线折叠手术。其中，2例患者术后需要调整缝线。在最后一次随访时，所有患者水平斜视的眼位在正位视6（Δ）以内，垂直斜视的眼位在正位视2（Δ）以内，均保持满意的眼位矫正。所有术前有复视的病例术后复视均消失。术后无并发症，眼位也无意外偏移。
采用这种可调节缝线技术的直肌折叠术可作为直肌切除术的替代方法，对于有眼前节缺血风险的患者或推荐较短麻醉时间的患者可能特别有用。
