Analysis of Clinical Effects on Severe Congenital Blepharoptosis by Frontalis Aponeurosis Flap Suspension

Abstract

Objective To evaluate whether orbicularis muscle bridge can affect the clinical results for treating severe congenital blepharoptosis by frontalis aponeurosis flap suspension surgery.Methods The subjects were selected from the in-hospital severe blepharoptosis patients of Fuzhou Southeast Eye Hospital from 2003 to 2006.All patients were randomly allocated into two groups:Group A(with orbicularis muscle bridge)and Group B(without orbicularis muscle bridge).There were 44 patients(51 eyes)in Group A and 49 patients(57 eyes)in Group B.All patients of these two groups were followed up and the near and long-term therapeutic effects were compared.Results In group A,42 eyes were completely corrected,6 eyes corrected,2 cases poorly corrected.In group B,51eyes completely corrected,6 eyes corrected,and none poorly corrected.There is statistical difference between the two groups using Ridit method(P＜0.01).Conclusions Making an orbicularis muscle bridge during frontalis aponeurosis flap suspension surgery can not contribute to the clinical results for treating severe congenital blepharoptosis.Orbicularis muscle bridge may limit the activity of frontalis aponeurosis flap because of local adhesion.Therefore we do not advocate orbicularis muscle bridge during frontalis aponeurosis flap suspension surgery for treating severe congenital blepharoptosis. Key words: frontalis aponeurosis flap suspension; severe congenital blepharoptosis; orbicularis muscle bridge
