肌皮瓣联合外1／3皮瓣法下睑袋成形术

Lower eyelid blepharoplasty with myocutaneous flap and lateral one-third skin flap

目的在肌皮瓣法手术操作基础上，于下睑外1／3区域联合应用皮瓣法，进一步提高睑袋整复效果。手术方法对37例行下睑袋成形术者，采用下睑缘切口，并将切15外侧延长线藏于外眦皱褶线内，先行肌皮瓣法操作，同时行外眦固定术，于下睑外侧1／3运用皮瓣法。结果术后恢复快，下睑皮肤平展，外眦部皮肤去除充分，张力适度。术后6个月至1年观察，无睑退缩、下睑外翻，外侧切口瘢痕隐蔽，随访效果满意。结论运用肌皮瓣法联合外1／3皮瓣法下睑袋成形术效果良好，外眦角自然，术后效果满意，达到下睑年轻化矫治的目的。

Objective To improve lower eyelid blepharoplasty by using myocutaneous flap and lateral one-third skin flap. Methods A total of 37 patients were recruited in this study and received lower eyelid blepharoplasty. Incision was made at the lower palpebral margin, and the extension of incision was＇ hided into the outer canthus rhytids. Myocutaneous flap was made first followed by the preparation of skin flap at the lateral one-third of the lower eyelid. Results All the patients experienced a quick recovery from the surgery. The excess skin at the lateral eanthus was completely removed, the incision was sutured under moderate tension, and the eyelid skin was flattened. No lid-retraction or lower eyelid ectropion was observed in the 6- to 12- month postoperative follow-up. The lateral incision scar was hidden and the operation outcome was satisfactory. Conclusions The lower eyelid blepharoplasty with myocutaneous flap and lateral one-third skin flap may lead to a satisfactory outcome with the formation of natural outer canthus angle and make the patients younger.
