目的分析外伤性下泪点外翻的原因和手术治疗的方法。方法对1996年3月—2004年5月54例外伤性下泪点外翻患者均采用手术提高下睑张力,局部皮瓣或游离植皮修复组织缺损。结果54人术后外观均明显改善,除15人下泪小管断裂阻塞外其余病例流泪症状均有不同程度改善,但有6人术后仍有轻度睑球分离,再从睑结膜面行睑板-结膜梭形切除术后效果良好。结论提高急诊处理技巧,分层细致缝合,减少组织缺损,从而减少外伤性下泪点外翻的发生;提高下睑张力,修复组织缺损,是矫正外伤性下泪点外翻的关键。
Objective To analyze the causes of traumatic lower eyelid valgus and the surgical treatment methods. Methods From March 1996 to May 2004, 54 patients with traumatic lower eyelid valgus were treated with surgery to improve the tension of the lower eyelid, and the local flaps or free skin grafts to repair the tissue defects. Results The appearances of 54 patients were significantly improved. Except 15 patients who had obstruction of laceration of the canaliculi, the symptoms of other patients’ tears were improved to some extent. However, there were still 6 patients with mild symblepharon after operation, Plate - conjunctival fusiform resection effect. Conclusions It is the key to correct the traumatic lower eyelid ectropion by improving the emergency treatment technique, stratifying and suturing stratified, and reducing the tissue defect, thereby reducing the occurrence of traumatic lower eyelid eversion; improving the lower eyelid tension and repairing the tissue defect.
