In Europe and America, acute mastoiditis usually appears as a complication of acute otitis media, and some patients develop subperiosteal mastoid abscesses. In Nigeria, however, most subperiosteal mastoid abscesses develop from chronic otitis media with cholesteatoma. Of the 16 patients with subperiosteal mastoid abscesses discussed, 11 (69%) had cholesteatoma and only five (31%) had granulation tissue in the mastoid cavity. The ideal treatment for these cases is modified radical mastoidectomy. Radiographic investigation of the mastoid can be useful in the diagnosis of cholesteatoma in the presence of a subperiosteal mastoid abscess.
在欧美，急性乳突炎通常表现为急性中耳炎的并发症，一些患者会形成骨膜下乳突脓肿。然而，在尼日利亚，大多数骨膜下乳突脓肿由伴有胆脂瘤的慢性中耳炎发展而来。在所讨论的16例骨膜下乳突脓肿患者中，11例（69%）有胆脂瘤，只有5例（31%）乳突腔内有肉芽组织。这些病例的理想治疗方法是改良乳突根治术。在存在骨膜下乳突脓肿的情况下，对乳突进行影像学检查有助于胆脂瘤的诊断。
