带结膜müller肌瓣转移修补术治疗顽固性义眼座暴露

The Management of the Intractable Exposure of Hydroxyapatite Inplants by Transposition of Conjunctiva-müller Muscular Flap

目的探讨顽固性羟基磷灰石义眼座暴露的处理方法。方法沿暴露的上半结膜缺损边缘在义眼座表面向上分离，两侧剪开形成结膜瓣，宽度与暴露区的直径相同，越过穹隆部后，继续在ｍüｌｌｅｒ肌与提上睑肌腱膜之间分离至睑板上缘，形成一含结膜、筋膜与ｍüｌｌｅｒ肌的带蒂组织瓣膜，覆盖于缺损区。结果随访６～１２个月，５例顽固性义眼座外露均愈合良好，未再复发。结论带结膜的ｍüｌｌｅｒ肌瓣转移修补术是修补顽固性义眼座暴露的有效方法。

Objective To investigate a repair method for intractable exposure of hydroxyapatite implants. Methods At the upper edge of conjunctival defect,the conjunctival tissues were separated by scissors along the surface of exposed base plate of ocular prosthesis to make a conjunctival flap in the size as same as the exposed area. This procedure of separation was continued between the mUller muscle and lavator through the fornix till the upper edge of tarsal plate to form a flap consisting of conjunctiva, aponeurosis and müller muscle,which was transposed to cover the defect area. Results 5 patients with intractable exposure of hydroxyapatite implants treated with the above procedure, no case was found to be recurred in 5 to 6 months of follow-up. conclusion The transposition of conjunctiva-müller muscular nap is an effective method for the management of the intractable exposure of bydroxyapatite implants..
