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。
Objective: To explore the clinical characteristics, diagnosis and endoscopic surgery of the posterior nostril polyps (CP) in posterior ethmoid sinus. Methods: The clinical data of 11 cases of posterior ethmoid CP patients who were treated in our hospital from January 2002 to June 2007 were analyzed. The clinical manifestations, the pathological changes in the nasal and sinus, the methods of endoscopic sinus surgery, the points for attention and the clinical curative effect were analyzed . Results: All the 11 cases underwent endoscopic sinus surgery. In the course of operation, 11 cases of CP root came from the posterior ethmoid sinus opening. Three cases (27.3%) had cyst in the posterior ethmoid sinus, 5 cases (45.4%) had obvious polyp in the sinus, and 3 cases (27.3%) showed polypoid sinusoidal mucosal edema. No significant intraoperative complications, follow-up 6 months to 3 years, an average of 1.2 years, no recurrence of polyps. Conclusion: The posterior ethmoid sinus of the CP from the posterior ethmoid sinus may be evolved from the sinus cyst. Endoscopic resection of polyps need to be open after the group of ethmoid sinus removal of lesions, complete removal of the lesion is not easy to relapse.
