目的 探讨泪囊鼻腔吻合术后泪囊炎复发的原因及再次手术治愈的可行性.方法 对2011年1月至2012年12月两年间我院收治的复发性泪囊炎15例行再次手术治疗,随访半年.结果 治愈14例,占93.33％,好转1例,占6.67％.随访半年,未再复发.结论 造骨孔小及位置错误、泪囊未完全切开、鼻腔与泪囊黏膜瓣吻合不牢固、吻合腔肉芽组织增生是泪囊鼻腔吻合术后泪囊炎复发的主要原因.该类患者可以通过再次鼻腔泪囊吻合术重建泪道,手术成功率高.“,”Objective To investigate the cause of recurrent dacryocystitis after dacryocystorhinostomy,and the feasibility of reoperation.Methods From January 2011 to December 2012,Fifteen eyes of 15 patients with recurrent dacryocystitis were reoperated,and the follow-up lasted for 6 months.The causes of recurrent dacryocystitis were investigated.Results In the fifteen cases,fourteen cases(93.33％) were cured,one patient(0.67％) were significant improved.No recurrent cases were found during the follow-up.Conclusion The possible causes for recurrence were as below:bone hole was too small or in wrong postion,lacrimal sac was not cut through,the mucosal flap anastomose unstable,and proliferation of granuloma occurred in anastomosis cavity.Re-dacryocystorhinostomy is feasible for recurrent patients.
