METHODS: Four dogs (4 eyes) underwent en bloc eyelid mass excision under general anesthesia. Measurements were made of the mass followed by free labial mucocutaneous graft retrieval, resection of the mass, and then transplantation of retrieved region of labial mucocutaneous tissue into the resulting defect.
RESULTS: Three patients underwent eyelid margin reconstruction with a free labial mucocutaneous graft. One patient received a pedicle advancement graft combined with a free labial mucocutaneous graft. In all cases, a length of 120%-150% of the eyelid defect was retrieved from the oral labia. Postoperative follow-up ranged from 6 weeks to 4 months. All cases had superficial graft necrosis and depigmentation of the donor tissue with total healing time taking up to 8 weeks. All cases had an esthetic and functional reconstruction.
CONCLUSIONS: This technique allows reconstruction of the majority of the eyelid margin, greater than that which can be closed primarily. Due to tissue sloughing, the healing time can be extended but cosmetic outcomes are good. Eyelid reconstruction utilizing a free labial graft restored a mucocutaneous margin and recreated a functional eyelid, thus avoiding trichiasis or secondary keratitis.
方法:四只狗(4只眼)在全身麻醉下进行整块眼睑肿块切除术。对肿块进行测量,然后进行游离的唇粘膜皮肤移植物取回,切除肿块,然后将取回的唇粘膜皮肤组织区域移植到所产生的缺损中。
结果:3例患者用游离唇粘膜皮肤移植行眼睑边缘重建术。一名患者接受了椎弓根前移移植物和游离的唇粘膜皮肤移植物。在所有情况下,从口腔阴唇恢复120%-150%的眼睑缺损。术后随访6周至4个月。所有病例均出现移植物表面坏死和供体组织色素脱失,总愈合时间长达8周。所有病例均进行了美学和功能重建。
结论:这项技术可以重建大部分眼睑边缘,大于主要可以关闭的。由于组织脱落,愈合时间可以延长,但美容效果良好。利用自由的唇移植物进行眼睑重建,恢复了粘膜皮肤边缘并重建了功能性眼睑,从而避免倒霉或继发性角膜炎。
