皮瓣松解加眼轮匝肌离断法矫治内眦赘皮

目的探讨一种操作简单、瘢痕隐蔽、适用于各型内眦赘皮的矫正都可获得较好效果的手术方法。方法依据近年来对于内眦赘皮病理解剖结构研究，认为内眦赘皮主要是由于上下睑眼轮匝肌于内眦韧带起始部位的错位，并影响皮肤的形态所形成，而并非是单纯的皮肤多余。以此研究成果为指导，设计了松解内眦皮肤与眼轮匝肌的粘连以及矫正内眦部位眼轮匝肌错位的矫治术式，即皮瓣松解加眼轮匝肌离断法。结果共矫治内眦赘皮57例，术后内眦部形态美观，眼裂增宽，瘢痕不明显，患者和医者都较满意。结论所设计术式适应范围较广，对矫治各型内眦赘皮皆能适用，效果较好。

Medial epicanthoplasty using skin redraping and orbicularis oculi muscle disconnection

Objective To explore a new simple epicanthoplasty method fit for various types of epicanthus with inconspicuous scar after operation.Methods As the latest studies showed that the anatomical structure of epicanthus is mainly due to the eyelid orbicularis muscle's dislocation at the starting point of the medial canthal tendon,which affects the skin appearance,rather than the traditional view that was merely the excess skin,we released the adhesions between the skin and the inner canthus orbicularis muscle,and corrected the dislocation of orbicularis muscle that was key to the operation,incised along with the line A′→B→A″→ C in the field of interior canthus,separated the subcutaneous fascia tissue,relaxed the subcutaneous fibrous cord,disconnect the orbicularis muscle's attachment point in the inner canthal fold,and then sutured and folded the inner canthal ligament.After sewing up point A′ and point A″,the released skin retracted naturally and formed a new inner canthal contour.Results From June 2008 to June 2009,57 cases of epicanthus patients accepted this surgery.After operation,the appearance of canthus was nice.Eye fissure got widen,and the scar was not obvious.Also there was a high satisfactory rate.Conclusions This method has a broad range of applications.It is suitable for various types of epicanthus correction.
