Chronic mastoiditis and subperiosteal abscess are rarely seen nowadays in most countries. Thirty-four cases of mastoiditis were reviewed to find out the prevalence of chronic mastoiditis in the east coast of Malaysia. Twenty (58.82%) of these cases were a sequelae of chronic suppurative otitis media with cholesteatoma. All the patients with chronic mastoiditis were more than six years old. Forty-five percent of cases with chronic mastoiditis had a well pneumatized mastoid air cell on the unaffected side. The occurrence of chronic mastoiditis or cholesteatoma in a well pneumatized mastoid is not really as rare as was thought to be. X-ray of the mastoids is very useful in diagnosing patients with chronic mastoiditis and cholesteatoma. Mastoiditis is uncommon in adults and whenever a case is seen, an underlying pathology like cholesteatoma should be suspected.
如今，在大多数国家，慢性乳突炎和骨膜下脓肿已较为少见。回顾了34例乳突炎病例，以了解马来西亚东海岸慢性乳突炎的患病率。其中20例（58.82%）是伴有胆脂瘤的慢性化脓性中耳炎的后遗症。所有慢性乳突炎患者年龄均超过6岁。45%的慢性乳突炎病例在未受影响侧有气化良好的乳突气房。在气化良好的乳突中发生慢性乳突炎或胆脂瘤的情况并不像人们认为的那么罕见。乳突X线检查对诊断慢性乳突炎和胆脂瘤患者非常有用。乳突炎在成年人中并不常见，一旦发现病例，应怀疑存在胆脂瘤等潜在病变。
