眉脂肪垫瓣转移修复上睑凹陷畸形

目的探讨眉脂肪垫瓣转移修复上睑凹陷畸形的手术方法特点,为上睑凹陷畸形的手术修复开创一种全新的手术方法———即具有血供的结构相似的脂肪组织转移修复上睑凹陷畸形。方法采用眉部下缘切口于上眶部外侧2/3眼轮匝肌及额肌下剥离显露整个眉脂肪垫,沿脂肪垫的内上外界切开脂肪垫至骨膜表面,于骨膜上分离掀起眉脂肪垫形成蒂在上眶骨下缘的脂肪垫瓣,通过重睑切口于眼轮匝肌下平面向上剥离隧道与眉部切口贯通,将眉脂肪垫瓣通过隧道向下翻转覆盖于上睑凹陷部位,缝合固定,并行重睑术。结果采用眉脂肪垫翻转瓣修复4例上睑凹陷畸形,手术成功,效果满意,无并发症,随访1年,脂肪无吸收,效果稳定。结论眉脂肪垫瓣翻转法是修复上睑凹陷畸形的新手术方法。突破了传统手术方法,具有以下特点:(1)转移到受区的脂肪组织具有血供,不存在吸收问题,远期效果持久稳定。(2)眉下脂肪垫与眶隔脂肪解剖结构极为相似,效果更佳、更自然。(3)供区与受区邻近,眉脂肪垫瓣易于转移。(4)供区无明显术后瘢痕,可同时修改眉型或行眉上提术。

Brow fat pad flap transfer for repairing depressed deformity of the upper eyelids

Objective To study the new surgical approach to repair depressed deformity of the upper eyelids by transferring brow fat pad flap that retains blood supply and similar construction with the orbital septum. Method An incision was made in the inferior margin of the brow to dissect and expose the brow fat pad under the orbicular muscle of the eye and frontal muscle plane in the lateral superior orbit, and the flap was removed from above the periosteum and pedicled under the orbital rim. Through the incision in the double-eyelid fold, a tunnel was dissected upward from the plane under the orbicular muscle to reach the brow incision. The brow fat pad flap was then turned over to cover the deformity, followed by fixation and suture of the flap and a double-eyelid operation. Result Four patients with the upper eyelid deformity were successfully treated using this new procedure with satisfactory results and no complications were encountered. Fat absorption was not observed in the one-year follow-up. Conclusion This procedure has the merits that (1) the fat tissue transferred to the recipient site has blood supply, thus fat absorption is prevented and the surgical results can be almost permanently maintained; (2) The similarity between the construction of the brow fat pad and the orbital septum fat may ensure better result with more natural look of the eyelids; (3) The donor site is adjacent to the recipient site to facilitate the brow fat pad transferring; (4) The operation leaves no obvious scars at the donor site.
