滲出性中耳炎の診断と治療効果の評価におけるCTの役割

[The role of computed tomography in the diagnosis of exudative otitis media and in the evaluation of the efficacy of its treatment].

滲出性中耳炎の管理は、その有病率の高さと安定した難聴という合併症の頻度の高さから、困難な問題である。罹患率が最も高いのは25歳から50歳であり、これはこの疾患に伴う社会的活動レベルの大幅な低下を物語っている。滲出性中耳炎の診断には、臨床検査や聴力検査では不十分なことが多い。コンピュータ断層撮影は、正確な診断、治療戦略の最適な選択、動態観察中の有効性の評価に信頼できる手段を提供する。

Management of exudative otitis media is a challenging problem in view of its high prevalence and frequent complications in the form of stable hearing loss. The highest morbidity rate is documented among 25 and 50-year old subjects which accounts for the substantially reduced level of social activity associated with this disease. Clinical examination and audiologic techniques are frequently insufficient to diagnose exudative otitis media. Computed tomography provides a reliable tool for the exact diagnosis, optimal choice of treatment strategy, and evaluation of its efficacy during dynamic observations.
