To evaluate the efficacy of Seprafilm(®) transplantation following adhesiolysis for preventing postoperative readhesion and improving surgical outcomes.
Primary blepharoplasty was carried out on both eyelids of 18 albino rabbits. After 2 weeks, a new skin incision was made, and adhesiolysis was performed on both eyelids. The rabbits were categorized into two groups, one with adhesiolysis alone in the left eyelid (control group), and the other with adhesiolysis with a Seprafilm(®) graft in the right eyelid (Seprafilm(®) group). The degrees of inflammation and fibrosis were examined with hematoxylin-eosin (HE) and Masson's trichrome stains. Expression of α-smooth muscle actin (α-SMA) was also immunohistochemically examined.
Eyelid examination immediately after the operation revealed mild swelling and hemorrhage in both groups, but these symptoms resolved after 1 week-2 weeks, and eyelid shape had recovered completely in both groups. Microscopic assessments demonstrated that the Seprafilm(®) group showed less inflammation and fibrosis than the control group. The Seprafilm(®) group also exhibited fewer α-SMA-positive cells than the control group.
Based on these findings, we conclude that Seprafilm(®) graft with adhesiolysis is an effective method for preventing postoperative readhesions after eyelid surgery.
评估粘连松解术后应用Seprafilm(®)预防术后再粘连及改善手术效果的疗效。
对18只白化兔的双眼进行初次眼睑成形术。2周后,在双眼做新的皮肤切口并进行粘连松解。将兔子分为两组,一组左眼睑仅行粘连松解(对照组),另一组右眼睑行粘连松解并植入Seprafilm(®)(Seprafilm(®)组)。用苏木精-伊红(HE)染色和Masson三色染色检查炎症和纤维化程度。还用免疫组织化学方法检测α-平滑肌肌动蛋白(α-SMA)的表达。
术后立即检查眼睑发现两组均有轻度肿胀和出血,但这些症状在1周-2周后消失,两组眼睑形状均完全恢复。显微镜评估显示,Seprafilm(®)组的炎症和纤维化程度低于对照组。Seprafilm(®)组的α-SMA阳性细胞也比对照组少。
基于这些发现,我们得出结论,粘连松解联合Seprafilm(®)植入是预防眼睑手术后再粘连的有效方法。
