改良额肌瓣悬吊术治疗先天性上睑下垂

目的观察改良额肌瓣悬吊术治疗先天性上睑下垂的疗效。方法对59例（73眼）先天性上睑下垂行改良额肌瓣悬吊术。男35例（44眼），女24例（29眼）。单眼45例，双眼14例。轻度6例（6眼），中度18例（20眼），重度35例（47眼）。结果73眼中66眼效果良好（90．41％），7眼好转（9．59％）。术后早期多有睑裂闭合不全，1—3个月后逐渐消失，随访6个月-3年，59例未见严重并发症，无复发者。结论额肌瓣有丰富的血供及神经支配，并且有足够的肌力提起上睑，具有符合生理和解剖的优点。改良额肌瓣悬吊术能矫正畸形及改善外观，是治疗先天性上睑下垂安全有效方法。

Treatment of congenital ptosis by modified frontal muscle suspension

Objective To observe the effect of modified frontal muscle suspension for congenital ptosis.Methods 59 cases (73 eyes) with severe congenital ptosis were operated with modified frontal muscle suspension,male 35 (44 eyes),female 24(29 eyes); monocular 45 cases,binocular 14 cased; mild ptosis 6 cases (6 eyes),moderate ptosis 18 cases (20 eyes),severe ptosis 35 cases(47 eyes).Results The effect rate was 90.41％ (66 eyes),the improvement rate was 9.59％ (7 eyes).In early postoperative time,lagophthalmos were often observed in the most cases but gradually disappeared after 3 months.During the 6 months to 3 years of follow-up,no relapse or serious complication was observed.Conclusion The frontal muscle holds not only rich blood-support and innervation,but also enough strength to raise the upper eyelid.The modified frontalis muscle suspension technique is a safe and effective method for congenital ptosis.
