对1982~1991年在芬兰坦佩雷大学医院和Mikkeli中心医院就诊并手术治疗的500例胆脂瘤患者进行了回顾性分析。年平均发病率为9.2/10万居民(3.7-13.9)，在研究期间，年发病率显着下降。在50岁以下的男性中发病率较高。在较低的社会群体中没有胆脂瘤疾病的积累。大多数(72.4%)的胆脂瘤患者有中耳炎发作。在胆脂瘤手术前，10.2%的患者行鼓室造瘘术，15.9%的患者行腺样体或扁桃体切除术。在没有中耳炎病史的完整鼓膜后发现胆脂瘤的患者占0.6%，在腭裂患者中占8%。在这项研究中，13.2%的患者有耳外伤或耳手术经历。
A total of 500 patients with cholesteatoma diagnosed and operated during 1982-91 in the region of Tampere University Hospital and Mikkeli Central Hospital in Finland were analysed retrospectively. The mean annual incidence was 9.2 per 100,000 inhabitants (range 3.7-13.9) and during the study period the annual incidence decreased significantly. The incidence was higher among males under the age of 50 years. There was no accumulation of cholesteatoma diseases in lower social groups. The majority (72.4%) of cholesteatoma patients had suffered from otitis media episodes. Tympanostomy was carried out in 10.2% and adenoidectomy or adenotonsillectomy in 15.9% of all cholesteatoma ears prior to cholesteatoma surgery. Cholesteatoma behind an intact tympanic membrane with no history of otitis media was verified in 0.6% of patients and in cleft palate patients in 8%. In this study, 13.2% of patients had ear trauma or ear operation in anamnes.
