介绍一种新术式——巩膜壳后硅胶球植入术 附:羟基磷灰石用于义眼台植入术

A new modality of retroscleral intraorbital implantation

眼球摘除后,若不放置眶内植入物,常发生上睑凹陷等并发症。因此,应尽量在摘除眼球的同时做一期眼窝成形手术。同仁医院眼科主要使用海绵状硅胶球作为眶内充填材料,但临床上常见植入物脱出。为此,笔者设计了巩膜壳后人工义眼台植入术,保留了直肌与巩膜的联系,以改善义眼台的运动;同时使硅胶球前面有双层自体巩膜,从而减少了硅胶球脱出的机会。10例巩膜壳后硅胶球植入手术,观察3个月～2.5年,临床效果满意。

Immediate placement of a silicone ball intraorbitally after enucleation prevents contraction of the orbit and retraction of the eyelids. The author placed the implant in the muscular cone behind the scleral shell, which prevented the frequent extrusion of the ball, and the intact attachment of the rectal muscles to the sclera was conducive to satisfactory motility of the ocular prosthesis. 8 cases received this modality of implantation with good results during a followup of 6～39 months. The author started using hydroxyapatite balls recently with promising success.
