不同术式羟基磷灰石义眼座植入的临床观察

Clinical observation of different implantation of hydroxyapatite（HA） ocular prostheses

目的观察不同术式的羟基磷灰石义眼座植入的效果及并发症。方法35例病例随机分为无包裹组19例和自体巩膜包裹组16例,通过不同手术方法植入羟基磷灰石义眼座。随访3m～18m。结果术后眼窝饱满度、义眼座活动度良好。主要并发症为结膜囊裂开,义眼座暴露,无包裹组暴露原因与全身营养不良有关,自体巩膜包裹组暴露原因与巩膜自溶有关。结论不同术式羟基磷灰石义眼座植入术后的并发症原因各不相同,提倡直接植入无包裹义眼座。

Objective To observe different hydroxyapatite （HA） implantation. Methods The operations were divided into 2 groups, different implantations of HA without or with autosclera covering. Follow-up was 3- 18 months. Results The HAs were fixed to orbit and moved well. The main complication was HAs＇ exposure. The reason for exposure was malnutrition in the group in which implantations of HA without sclera covering and sclera autolyze in the group in with implantations of HA with autosclera covering. Conclusions The reasons for complication were different in different bydroxyapatite （HA） implantation. We should advocate the implantation of HA without sclera covering.
