改良Z成形术在重度内眦赘皮矫治中的应用研究

Application research on severe epicanthoplasty by method of modified Z plasty

目的:探讨重度内眦赘皮矫正的较佳手术设计方法。方法:利用Z成形术的基本原理,对Z字上下臂及中轴线的位置、形态、方向、大小及侧臂与长轴夹角等多方面进行改良设计,明确固定标志,形成完整的、合理的重度内眦赘皮手术设计方案。结果:本组29例患者,经6～12个月随访,术后赘皮消失、泪阜外露适度、睑裂开大并与内眦间距比例协调、内眦角形态良好、睑裂美观自然,所有患者内眦处手术痕迹不显。结论:本改良Z成形术矫治重度内眦赘皮的方法,具有术后效果好、无复发、手术痕迹不显,同时标志点明确、操作简单、易于掌握,具有一定的临床应用价值。

Objective To investigate a good way of design for correction of severe epicanthal fold.Methods By applying its basic theorem,we concisely designed Z plasty,in which the central axis,upper and lower arms are each adjusted according to its position,shape,direction,size and included angle.After affixing markers,intact and rational design proposal was yielded.Results After 6～12 months follow-up,29 cases in the group manifested good results with no obvious scar,and palpebral fissure,lacrimal caruncle,angle of eye medial are in harmony.Conclusion The resultant scar is mild and relapse-free with no trail of operation.The results obtained by using modified Z plasty for epicanthoplasty are very satisfactory.We propose the clinical use of this technique for correction of epicanthal deformities with simplified manipulation and cosmetic effect.
