摘要
【目的】探讨保留自体巩膜而避免损伤眼外肌的羟基磷灰石义眼座植入法。【方法】选择 2 2例 (2 2只眼 )单眼无光感患者施行保留自体巩膜和眼外肌的羟基磷灰石义眼座植入手术 ,该组病例年龄 7～ 6 7岁 ,平均 2 9.1岁 ,男 15例 ,女 7例 ,3例为白塞氏病 ,9例为陈旧性眼外伤继发角巩膜葡萄肿 ,8例为陈旧性眼球穿通伤继发眼球萎缩 ,2例为绝对期青光眼继发大泡性角膜病变。眼球内容剜除术后剪断视神经和中央血管 ,仅离断外直肌而不切开巩膜 ,把羟基磷灰石义眼座从颞侧植入肌锥 ,再把外直肌复位。【结果】 9例 (9只眼 )患者早期炎症反应重 ,3周后所有病例球结膜充血和水肿完全消失 ,安置义眼外观理想 ,追踪观察平均 12个月未发现结膜裂开和义眼座暴露现象。【结论】保留自体巩膜的羟基磷灰石义眼座植入法是一种效果确切、可避免眼外肌损伤的手术方法。
Objective To explore the method of avoiding damage of sclera and extraocular muscle during the hydroxyapatite orbital implant. Method Twenty-two unilateral blind cases underwent hydroxyapatite orbital implantation that maintain sclera and extraocular muscle. The age of the patients range from 7 to 67 with an average of 29.1 years old. Of them 15 were male and 7 were female. The primary ocular diseases were Behcet′s disease in 3 cases, obsolete ocular trauma with secondary sclerocorneal staphyloma in 9 cases, obsolete ocular atrophy after perforated ocular injury and bullous keratopathy secondary to absolute glaucoma in 2 cases. After evacuating the contents of the eye bulbus, the optic nerve and central vessels were cut, then separating the extra rectus muscles without opening the sclera, finally implanting the hydroxyapatite in the muscle cone through temporal side and relocating the extra rectus muscle. Result 9 cases (9 eyes) had severe conjunctival edema after the early stage of the operation, but it detumescence 3 weeks completely. The outlooking was satisfactory after 3 week in all cases. There was no conjunctival dehiscence and hydroxyapatite exposure within 12 months of follow-up control. Conclusion This way of hydroxyapatite orbital implantation is safe with definite result as well as minimum injury to extra-ocular rectus muscles.
