鼻侧腱膜内固定法内眦赘皮矫正术

Epicanthus diorthosis using lateral nasal aponeurosis inner fixing method

目的:探讨一种矫正内眦赘皮更简单、切口隐蔽、瘢痕不明显的术式。方法:通过重睑线鼻侧小切口将内眦赘皮皮下筋膜、内眦韧带及眼轮匝肌肌纤维充分松解、分离,部分切除,把内眦赘皮向鼻侧腱膜推移,并将内眦赘皮皮下包括部分真皮缝合固定在鼻侧腱膜上。结果:通过此方法矫正轻、中度内眦赘皮240例。144例获随访,最短1月,最长1年,内眦赘皮消失。11例术后出现线结反应硬结形成占7.6%,3～6个月消失;6例效果欠佳内眦赘皮复发占4.2%,半年后再用此方法修复矫正得到满意效果。结论:此方法手术创伤小,恢复时间短,术后瘢痕不明显,是内眦赘皮矫正的一种有效适用方法。

Objective This article aimed at probing a simpler, feasible method for the correction of epicanthus with inconspicuous incision and scar. Methods Through a small incision next to the nose beside the fold of upper eyelid, the canthal ligament of subcutaneous fascia and muscle fibers of orbicularis can be loosened and separated as far as possible, so portion of which can be resected. And the Epicanthus can be pushed towards to lateral nasal aponeurosis, so subcutaneous tissue including partial corium of epicanthus were then sutured and fixed to lateral nasal aponeurosis. Results Through this way, we corrected 240 cases of epicanthus with slight and moderate degree. 144 cases were followed up for one month to 1 year. The epicanthus disappeared post operation. Knot yarn reaction occurred after operation in 11 cases （7.6%） but eventually disappeared within 3 to 6 months. Epicanthus recrudesced in 6 cases （4.2%） and were corrected after 6 months by the same method and finally got satisfactory results. Conclusion The advantages of this method： less tissue damage, short recovery time and imperceptible scars post-operation. It is an effective and appropriate method for correcting epicanthus.
