自体角膜缘移植联合球结膜移植治疗翼状胬肉

Transplantation of limbal autograft and bulbal conjunctive for patients with pterygium

目的探讨治疗巨大翼状胬肉及复发性翼状胬肉的有效方法。方法对27例(27眼)巨大翼状胬肉及复发性翼状胬肉行胬肉切除加自体球结膜移植或自体角膜缘移植联合球结膜移植术。Ⅰ组8例(自体球结膜移植组)翼状胬肉单纯切除后取同眼颞上方球结膜移植于巩膜暴露区,Ⅱ组19例(自体角膜缘移植联合球结膜移植组)翼状胬肉单纯切除后取同眼颞上方结膜角膜缘上皮组织移植于巩膜暴露区。所有病例均在手术显微镜下操作。结果术后平均随访9.4月,自体球结膜移植组复发1例,自体角膜缘移植联合球结膜移植组未见复发。结论自体角膜缘移植联合球结膜移植治疗翼状胬肉疗效良好。

Objective To investigate an effective method for treatment of huge and recurrent pterygium. Methods Excision of pterygium associated with transplantation of bulbal conjunctiva or limbal - conjunctival autograft were performed in 27 patients （27 eyes） with huge and recurrent pterygium. The patients were divided into two groups. There were 8 cases in group Ⅰ（excision of pterygium associated with transplantation of bulbal conjunctiva） , 19 cases in group Ⅱ（excision of pterygium associated with transplantation of limbal -conjunctival autograft）. All the patients were treated under surgery microscope, Results The mean follow up time was 9.4 months after surgeries. Pterygium occurred again postoperatively in one eye with transplantation of bulbal eonjunetiva. No recurrent pterygium was found in eyes with transplantation of limbal autograft. Conclusions Transplantation of limbal autograft and bulbal conjunctiva appears to be a promising treatment for pterygium.
