目的:评价利用邻近角巩膜缘结膜瓣重建翼状胬肉术后角巩膜缘的手术方法。方法:对100例翼状胬肉手术进行了前瞻性非随机对照研究,局麻下行翼状胬肉切除术。切除后,切口两侧带有临近角巩膜缘组织的两个结膜瓣切开后缝合,重新恢复角结膜缘。角巩膜缘重建结果用印迹细胞学方法评价。结果:印迹细胞学方法证实角巩膜缘完全重建。随访6-24(平均14)mo,术后复发率为4%。两位手术者所做手术后复发率差异小(3%vs4%)。在复发的病例中发现,包括粘液细胞增生和鳞状化生的角巩膜缘解剖结构改变。结论:角巩膜缘邻近的结膜瓣移植术是一种安全简单的翼状胬肉手术方法,可以完全重建角巩膜缘,术后复发率低。
Objective: To evaluate the surgical approach of reconstructing the limbal sclera of the pterygium using the conjunctiva flap of the scleral limbus. Methods: A prospective, nonrandomized, controlled study of 100 patients with pterygium surgery was performed. Atrial pontotomy was performed under local anesthesia. After resection, the two conjunctival flaps with adjacent corneal margins on both sides of the incision were incised and sutured to restore the corner conjunctiva. The results of limbal reconstruction were evaluated by Western blot cytometry. Results: Implant cytology confirmed complete reconstruction of the limbus. Follow-up 6-24 (average 14) mo, postoperative recurrence rate was 4%. The difference in recurrence rates between the two surgeries was small (3% vs. 4%). In cases of recurrence, changes in the anatomy of the limbus and limbus including mucous cell hyperplasia and squamous metaplasia were observed. CONCLUSION: Conjunctival flap transplantation near the limbus is a safe and simple method for the surgery of pterygium. The angle and scleral margin can be completely reconstructed and the postoperative recurrence rate is low.
