目的：鱗狀乳突部氣房發育不良與中耳炎關係密切。本文特以腦部電腦斷層為題材，窺見以前中耳炎在本國兒童及青少年的盛行狀況。方法：在2008年7月及2011年6月間，共計14,812成年人（男7,650，女7,162）曾於北部某區域醫院接受腦部電腦斷層，年齡55.2 ± 20.1（平均值±標準差）歲。把軸狀切面設定為骨視窗（中心值350 HU，窗寬2,000 HU）進行判讀。結果：共計329名（男167，女162）納入本研究，年齡67.4 ± 16.5歲。具有至少一側之鱗狀乳突部氣房發育不良者在老年族群之比例（4.05%，211 of5,212），遠高於中年族群（1.67%，95 of 5,678）或成年族群（0.59%，23 of 3,922）。結論：從遺留於現代老年族群鱗狀乳突部氣房發育不良之高比例，可以推測在半個世紀以前之本國兒童或青少年發生中耳炎併發症的機會應遠高於後來的時代。

Purpose: Hypocellular squamomastoid is closely related to otitis media. With this study, we aim at understanding the former prevalence of otitis media in children and adolescents by examining adult patients who have recently received brain computed tomography.Methods: From July 2008 to July 2011, 14,812 adults, including 7,650 men and 7,162 women, had received brain computed tomography at a regional hospital in North Taiwan. They were aged 55.2±20.1 (average ± SD). We reviewed each axial section under bone window (WC 350, WW 2,000).Results: Three hundred and twenty-nine persons, including 167 men and 162 women, are enrolled. They are aged 67.4 ± 16.5. The prevalence of hypocellular squamomastoid in the aged population (4.05%, 211 of 5,212) is higher than those in the middle-aged population (1.67%, 95 of 5,678) and common-adult population (0.59%, 23 of 3,922).Conclusion: According to the residual high prevalence of hypocellular squamomastoid in the aged population, the prevalence of otitis media complication in Taiwanese children and adolescents must be higher in half a century ago than in the following years.
