Investigation into the underlying disease causing an aural polyp is often hampered when the polyp itself obscures the tympanic membrane. This retrospective analysis of 65 patients undergoing aural polypectomy was carried out to identify any predictive factors for underlying cholesteatoma and to determine a correct management strategy for aural polyps. The duration of symptoms, size of polyp, size of conductive component of hearing loss and bacteriology of otorrhoea were unhelpful as predictors of the underlying disease. Radiological evidence of bony erosion of the mastoid is a useful sign of cholesteatoma when present. Aural polypectomy resulted in 58.3 per cent of ears becoming inactive. It is proposed that aural polypectomy and histological assessment should be employed as initial treatment with mastoid exploration reserved for those ears thus identified as high risk for cholesteatoma.
当耳息肉本身遮挡住鼓膜时，对引起耳息肉的潜在疾病的调查常常受到阻碍。对65例行耳息肉切除术的患者进行了这项回顾性分析，以确定潜在胆脂瘤的任何预测因素，并确定耳息肉的正确管理策略。症状持续时间、息肉大小、听力损失传导成分的大小以及耳漏的细菌学检查作为潜在疾病的预测指标并无帮助。当存在乳突骨质侵蚀的影像学证据时，是胆脂瘤的一个有用迹象。耳息肉切除术使58.3%的耳朵病情不再进展。建议采用耳息肉切除术和组织学评估作为初始治疗方法，而乳突探查仅用于那些被确定为胆脂瘤高危的耳朵。
