Levator transposition is used as a unilateral procedure for patients with both ptosis and aberrant movements of the eyelid. Muscular neurotisation occurs in the transposed levator muscle and thus some levator function is restored.
We reviewed 35 patients who had undergone a levator transposition procedure.
Twenty-eight patients had jaw-winking ptosis, three had cyclic oculomotor palsy and four had a third nerve palsy with aberrant regeneration. The follow-up period was between 1 and 39 months (mean 12 months). Eighteen patients were followed up for at least 12 months and their results were analysed as a separate group.
The levator function attained following transposition is related to the pre-operative voluntary function and this relationship is statistically significant (Wilcoxon test p < 0.001). Maximal levator function may not be achieved until 12 months post-operatively. The procedure is successful in abolishing aberrant eyelid movements and treating ptosis but the majority of patients require an additional levator resection to achieve a satisfactory lid height.
提上睑肌转位术用于治疗上睑下垂且伴有眼睑异常运动的患者。转位后的提上睑肌会发生肌肉神经化，从而恢复部分提上睑肌功能。
我们回顾了35例行提上睑肌转位术的患者。
28例患者为下颌瞬目综合征性上睑下垂，3例为周期性动眼神经麻痹，4例为动眼神经麻痹伴异常再生。随访时间为1至39个月（平均12个月）。18例患者随访至少12个月，并将其结果作为一个单独的组进行分析。
转位后获得的提上睑肌功能与术前自主功能相关，且这种关系具有统计学意义（Wilcoxon检验p < 0.001）。术后12个月才能达到最大提上睑肌功能。该手术成功消除了异常眼睑运动并治疗了上睑下垂，但大多数患者需要额外进行提上睑肌切除术才能获得满意的睑裂高度。
