鼻腔混合瘤的临床分析

目的探讨鼻腔混合瘤的临床表现、病理特点及治疗方法，以提高对此病的诊疗水平。方法回顾性分析6例鼻腔混合瘤患者的临床资料，根据术前鼻内镜和鼻窦CT等术前评估选择手术径路；其中2例行鼻侧切开术，4例行鼻内镜下肿瘤切除术。结果鼻腔混合瘤原发于鼻中隔者5例、鼻咽顶后壁1例；术后随访3年，5例痊愈，1例复发。结论鼻腔混合瘤虽属良性肿瘤，但术后易复发，首次彻底切除是预防复发的关键，术后需定期随访。

All patients underwent preoperative nasal endoscopic examination and CT scan evaluation, according these examinations to chose the surgical approaches. Of them, lateral rhinotomy and endoscopic resection were applied to 2 and 4 cases respectively.ResultsThe diagnosis of pleomorphic adenoma was confirmed by postoperative pathological examination in all cases. As for the primary site of NPA, 5 were located at the nasal septum and one at the roof of nasopharynx. The 3 year follow up demonstrated recurrence in one case and cure in 5.ConclusionNPA is a benign tumor with high recurrence rate.
