方法：对49例50眼慢性泪囊炎已行泪道植管术(单植入直硅胶管或球头硅胶管)但仍有溢泪或拔管后短期内复发患者行直硅胶管联合球头硅胶管治疗。随访1a观察临床疗效。

结果：接受再次的联合植管手术的患者，5例5眼术后3mo泪道冲洗不通，手术无效； 其余44例45眼患者带管期间及拔管后1a复查泪道冲洗通畅，有效率90%。

结论：直硅胶管联合球头硅胶管治疗常规泪道植管术后复发性泪囊炎效果确切，复发率低，并值得向慢性泪囊炎初次手术者推广应用。

METHODS:Forty-nine patients(50 eyes)with recurrent chronic dacryadeitis who had treated with straight silicon tube or spherical headed silicon tube were implanted with straight silicon tube combined with spherical headed silicon tube.Patients were followed up for 1a to observe the curative effect.

RESULTS:The operation was invalid in 5 cases(5 eyes)as their rigation of lacrimal passage was failure.The remaining 45 eyes in 44 cases were cured with no epiphora.The cure rate was 90% at 1a after the tubes were extracted.

CONCLUSION:The joint implantation of straight silicon tube and spherical headed silicon tube is an effective and safe technique in treatment of post-operative patients with recurrent chronic dacryadeitis,and worthy of widely use in patients with chronic dacryadeitis who have never been treated with surgeries.
