应用膨体聚四氟乙烯治疗面颊凹陷并同侧面瘫

THE APPLICATION OF EXPANDED POLYTETRAFLUOROETHYLENE IN THE TREATMENT OF FACIAL DEPRESSION WITH FACIAL NERVE PALSY

目的探讨膨体聚四氟乙烯在修复面颊凹陷及面瘫的作用。方法１９９７年２月～１９９８年７月，应用膨体聚四氟乙烯片状材料填充半侧面颊凹陷，同时悬吊治疗同侧面瘫６例，术后获得２～１６个月随访。结果面颊凹陷修复后，患侧与健侧对称，皮肤表面无异常，质地柔软。面瘫修复后，眼睑能完全闭合，口角静态时患侧与健侧基本对称，动态时患侧与健侧略有差异，但较术前明显改善。结论应用膨体聚四氟乙烯治疗面颊凹陷合并同侧面瘫具有安全，疗效确切且稳定，手术操作简便易行，创伤小，恢复快。

Objective In order to investigate the effect of expanded polytetrafluoroethylene (e PTFE) in repair of facial depression. Methods From February 1997 to July 1998. The e PTFE was used as a filling and suspending material for facial depression and facial nerve palsy in 6 cases. They were followed up for 2～16 months. Results After filling of the facial depression, the deformed side of the face became symmetrical to that of contralateral side, and those following the suspending technique using this material the affected eyelids could close completely and the oral corners were symmetrical in its static status. Conclusion The expanded PTFE was a safe, biocompatible and easily applied material, especially served as a filling or suspending material in the repair of facial depression with facial nerve palsy.
