上睑中央大面积缺损再造术

应用下睑板结膜瓣对4例上睑中央大面积缺损进行眼睑再造。这些缺损均发生于局部癌变组织切除之后，缺损长度均超过1／2，术后未发生睑内翻和下睑退缩，眼睑功能正常，面容满意，随访6月～6年．肿瘤未复发。本文讨论不同大小上睑缺损的修复和设计下睑板结膜瓣的方法，同时也讨论了下睑板沟切口和灰线切口的优缺点。作者认为上睑中央1／2长度左右的缺损和超过2／3的缺损可分别采取下睑板沟切口和灰线切口。

Reconstructive operation for large central defect of the upper eyelid

4 cases of full thickness large central loss of the upper eyelid were reconstructed with lower tarso-conjunctival flaps. These defects were all produced as the results of carcinoma excission. The length of These defects were greater than 1/2 of the lid margin. No entropion and lid retration of lower eyelid had been observed. All 4 eyes achieved good functional and aesthetic effect. No relapses were observed during a follow-up of 6-72 months. The methods which were applied to repair the various upper eyelid defects and disingns which were made for lower tarso-conjunctival flaps were discussed. The advantages and disadvantages of lower tarsal sulcus and intermarginal sulcus incision were also discussed. The authors consider that in repairing a full thickness upper eyelid loss of about 1/2 and over 2/3 of the tid length, a lower tarsal sulcus incision and a gray line incision might be used respectively.
