To evaluate the outcomes of a surgical technique using buccal mucosal membrane graft for correction of cicatricial lower eyelid retraction.
Twelve patients with unilateral cicatricial lower eyelid retraction were enrolled in the study. All patients underwent a four-step surgical technique consisted of release of scars, midface lift, transfer of buccal mucosal membrane to posterior lamella as spacer graft, and canthal tightening. All patients were followed for at least 12 months.
Mean preoperative Margin-to-Reflex-Distance 2 (MRD2) was 7.73 ± 1.10 mm, compared to mean postoperative MRD2 of 5.04 ± 0.49 mm (P < 0.0001). The mean improvement in retraction was 2.69 mm. Postoperative scleral show was present in only one case and no major complications were observed.
The four-step procedure (scar release, midface lift, buccal mucosal graft and canthal tightening) was an effective procedure to correct cicatricial lower eyelid retractions with acceptable outcomes and a low morbidity rate.
评估使用颊黏膜膜移植物矫正瘢痕性下眼睑退缩的手术技术的结果。
本研究纳入了 12 例单侧瘢痕性下眼睑退缩的患者。所有患者均接受四步手术治疗，包括松解瘢痕、中面部提升、颊黏膜向后板转移作为间隔移植物、以及内眦收紧。所有患者均随访至少 12 个月。
术前平均睑裂高度-反射距离 2（MRD2）为 7.73±1.10mm，术后平均 MRD2 为 5.04±0.49mm（P<0.0001）。退缩的平均改善量为 2.69mm。仅 1 例出现巩膜暴露，无严重并发症。
四步手术（松解瘢痕、中面部提升、颊黏膜移植物和内眦收紧）是一种治疗瘢痕性下眼睑退缩的有效方法，具有可接受的效果和较低的发病率。
