目的：观察睑缘后唇灰线切开联合毛囊根部摘除术矫正儿童先天性双行睫的临床疗效。

方法：收集1990-09/2015-10我院收治的先天性双行睫患者8例13眼，在全身麻醉或局部麻醉下行睑缘后唇灰线切开联合毛囊根部摘除术。术后随访3mo～5a，观察患者预后情况。

结果：术后48h，所有患者伤口已愈合，不影响活动。术后随访观察，所有患者双行睫均完全矫正，睑缘无畸形和手术瘢痕形成，睑缘灰线切口处愈合平整； 眼睑前缘不受手术干扰，未发现眼睑内外翻及倒睫； 睑缘后唇锐利平整，保持角度与眼球表面接触，无内外翻及导泪异常，无残存睫毛，无刺激症状，角膜表面浸润恢复。

结论：睑缘后唇灰线切开联合毛囊根部摘除术矫正儿童先天性双行睫疗效确切，复发率低，符合眼睑生理功能与外观要求，且手术操作简便。

METHODS: Thirteen eyes of 8 patients with congenital districhiasis admitted to our hospital from September 1990 to October 2015 were collected. Under general anesthesia or local anesthesia, all the patients were admitted gray line incision and hair follicle root excision. The patients were followed up for 3mo-5a to observe the prognosis.

RESULTS: All the patients' wounds had healed and the eyelid activity was not affected 48h after the operation. Patients were followed up and observed and their districhiasis had completely corrected after surgery. The incision of the gray line of the eyelid margin healed smoothly, no eyelid margin deformity and surgical scar formated. The anterior eyelid lashes were not disturbed by surgery and no entropion, ectropion or trichiasis were found. The posterior lip of the eyelid margin is sharp and flat, keeping the angle of contact with the surface of the eyeball. No entropion or ectropion formation,and no abnormal tear conduction were found, no residual eyelashes. There was no corneal irritation, and the corneal surface infiltration lesion healed.

CONCLUSION: Gray line incision and hair follicle root excision is effective surgery in correction of congenital districhiasis in children with low recurrence rate. The operation is simple and meets the requirements of eyelid physiological function and appearance.
