来源于后组筛窦的后鼻孔息肉的诊断和治疗

目的:探讨后组筛窦的后鼻孔息肉(CP)的临床特征、诊断以及鼻内镜下手术方法.方法:总结2002年1月～2007年6月收治的11例后组筛窦的CP患者的临床资料,分析其临床表现、鼻腔及鼻窦内病变情况、鼻内镜手术方法及注意要点以及临床疗效.结果:11例均在鼻内镜下完成手术.术中见11例CP根部均来自后组筛窦开口处.后组筛窦内3例(27.3%)伴有囊肿,5例(45.4%)窦内有明显息肉,3例(27.3%)表现为窦内黏膜水肿息肉样变.术中无明显并发症,术后随访6个月～3年,平均1.2年,无息肉复发者.结论:后组筛窦的CP多来自后筛窦口,可能由窦内囊肿演变而成.鼻内镜下切除息肉同时需开放后组筛窦清除窦内病变,彻底清除病变后不易复发.

Diagnosis and therapy of choanal polyps from posterior ethmoid sinus

Objective:To investigate the clinical feature,diagnosis and endoscopic surgery of choanal polyps(CP) from posterior ethmoid sinus.Method:Eleven cases with CP from posterior ethmoid sinus treated by endoscopic endonasal surgery between January 2002 to June 2007 were retrospectively reviewed.Clinical manifestation,intranasal and intrasinus lesions,methods and attensions of endoscopic surgery and therapeutic effects were analysed.Result:All cases were treated by endoscopic surgery and CP were found originated from posterior ethmoidal ostium.Lesions in posterior ethmoid sinus included 3(27.3%) cyst,5(45.4%) polyp and 3(27.3%) mucosal edema.No operation complications were observed.The follow-up period ranged from 6 months to 3 years(mean 1.2 years) and no recurrence was founded.Conclusion:Most of CP originated from posterior ethmoidal ostium and its formation might be related to the cyst in the sinus.Endoscopic surgery represents a minimally invasive and highly successful procedure,complete removal of CP and lesions in the sinus can reduce the recurrence.
