摘要目的 探讨切开法重睑成形术之切痕隐蔽,以提高手术效果.方法 50例采用在睑缘上近睫毛根部的睑缘切口,剪除睑板前大部分疏松组织,做5针切口上唇真皮与睑板的内固定缝合.适当剪除切口上唇宽1～3 mm的皮肤.另50例为对照组,采用常规切口在距睑缘上6～8 mm处切开,剪除睑板前大部分疏松组织,做5针切口下唇皮肤与睑板的固定缝合.结果 5 d拆线时,睑缘切口者肿胀均较常规切口者轻,切痕隐蔽,重睑外形均颇满意,睫毛无损伤.常规切口者则切痕明显可见.结论 对比两种切口的重睑成形术,睑缘上切口者优势在于切痕隐蔽、手术创伤小、肿胀轻.但手术操作难点在于,缝合固定真皮与睑板使两侧重睑线圆滑弧度对称良好.

abstractsObjective To evaluate results of double eyelid operations with different incisions.Methods 100 patientswere selected randomly from out-patients that accepted double eyelid operation.Half of them were objected to double eyelid operation through a palpebral marginal incision.Incision was designed along the palpebral margin,close to boots of eyelashes.Most of the subcutaneous tissues was cut and removed,and then dermis and tarsal plate were fixed with 5 stitches of suture.About 1-3 mm wide of skin along superior margin was removed reasonably.In another 50 cases.double eyelid operation was performed with conventional incision.Incision was designed 6-8 mm far from the palpebral margin.Most of the subcutaneous tissues was removed.and then dermis and tarsal plate were fixed with 5 stitches of suture.Results Postoperative results were evaluated 5 days and 1 month after operation respectively.Postoperative double eyelid shapes were all satisfled in two groups.Swollen eyedids and scar were more inconspicuous in the cases with the palpebral-marginal incision without impairment on eyelashes.Conclusion Compared with double eyelid operation with conventional incision,blepharoplasty with palpebral margin incision has the same results but with lighter impairment,milder hydropsia and more inconspicuous scar.The key point of this procedure is the fixation of dermis and tarsal plate,keeping a good radian of double eyelid line.
