义眼台植入矫正眼球内容剜除术后上睑凹陷畸形

Implanting hydroxyapatite sphere post-sclerally at the second stage to correct the deformity of anophthalmos after evisceration

为了Ⅱ期矫正眼球内容剜除术后上睑凹陷畸形，采用羟基磷灰石（简称HA）义眼台巩膜后植入。手术方法：切开球结膜及Tenon氏筋膜，广泛剥离，松解并充分展开残存巩膜，沿内、下直肌和外、上直肌间将巩膜劈为两半，剪断视神经，置HA球于肌锥腔内，分别缝合巩膜后唇、前唇、筋膜和球结膜。21例病人均取得较满意效果。本手术简单、安全、成功率高，配戴义眼后外观满意，活动较佳。

To correct the depression of upper eyelid and anophthalmos after evisceration atthe second stage, hydroxyapatite (HA) sphere was implanted into orbit postsclerally. Operativeprocedure: incision was made on the conjunctiva and Tenon's facia. Afeter wide desection, theremaining sclera was extended and flattened. Then, the sclera was incised into two halvesobliquely between the inner and lower rectus muscles and outer and upper rectus muscles. Aftercutting off the orbital nerve, the HA sphere was placed into the muscle cone. The rear and frontlip of the sclera,the facia and the conjunctive were sutured respectively. 21 patients received thisoperation and the result was satisfactory. After the prosthetic eye was fitted into the conjunctivalsac, its appearance and the movement became good. This technique is simple and safe, and riskless.
