改良的额肌瓣悬吊术治疗幼儿先天性重度上睑下垂

The study of modified frontal muscle flap suspension surgery for severe congenital blepharoptosis in infants

目的 观察额肌瓣悬吊术矫正 1～ 3岁幼儿重度上睑下垂的临床效果。方法 按照重睑成形术原则设计重睑线 ,在眉弓下缘眶上切迹外侧 0 .5cm作长 1.0～ 1.5cm之辅助切口。在眶上缘额肌附着处制一宽约 2 .0～ 2 .5cm的似扇形额肌瓣 ,固定在睑板上。结果 治疗 2 0例 (30眼 ) ,除 1例 (1眼 )轻度欠矫外 ,余 2 9眼均取得满意效果 ,双重睑形成自然美观 ,无畸形。结论 此方法操作简单 ,效果满意 ,对额肌损伤小 ,似扇形额肌瓣更接近提上睑肌走向 。

Objective To observe clinical effects of frontal muscle flap suspension surgery for severe congenital blepharoptosis in of infants 1～3 years old .Methods Dual eyelid line was designed according to the rule of dual eyelid plastic operation. A 1.0～1.5cm adjuvant incision was made out of supraorbital incisure 0.5cm. A sector like frontal muscle flap side 2.0～2.5cm was designed in supraorbital margin frontal muscle attachment. Frontal muscle flap was sewn to the upper edge of tarsal plate. Results 29 eyes were cured among 30 eyes, the appearance of dual eyelid was natural, pretty and no deformity. Clinical effect of 1 eye was little different correction. Conclusion The operative method is simple, effective and small injury to brow muscle. The trend of sector like frontal muscle flap is close to levator muscle of upper eyelid.
