Patients with chronic progressive external ophthalmoplegia (CPEO) are often disabled by ptosis; however, conventional ptosis surgery may induce lagophthalmos and exposure keratitis. Ten patients with CPEO underwent ptosis correction via bilateral frontalis suspensions, using monofilament synthetic material. Three of these patients were also treated with lower eyelid horizontal tightening. The frontalis sling was adjusted to provide a firm linkage between the eyebrow and eyelid, but was loose enough to allow eyelid closure when the frontalis muscle is relaxed. All patients experienced lessening of ptosis and relief from visual obstruction. One patient required reoperation of one eyelid for undercorrection. No lagophthalmos or corneal complications occurred. The rationale for treatment, preoperative evaluation, and operative procedure in CPEO is discussed herein.
慢性进行性眼外肌麻痹(CPEO)患者常因上睑下垂而致残;然而,传统的上睑下垂手术可能会导致兔眼和暴露性角膜炎。10例CPEO患者采用单丝合成材料经双侧额肌悬吊术进行上睑下垂矫正。其中3例患者还接受了下睑水平收紧术。调整额肌吊带,使其在眉毛和眼睑之间提供牢固的连接,但又足够松弛,以便额肌放松时眼睑能够闭合。所有患者的上睑下垂均有所减轻,视觉障碍得到缓解。1例患者因矫正不足需对一只眼睑进行再次手术。未发生兔眼或角膜并发症。本文讨论了CPEO的治疗原理、术前评估和手术方法。
