Abstract

当科で手術した先天性真珠腫症例39例について、Potsicの進展度分類別に初診年齢、受診動機、術式(乳突腔の処理法と伝音連鎖再建)、聴力予後について検討した。Stage Iが4例(10.2%)で平均年齢4歳、Stage IIが4例(10.2%)で平均年齢5.2歳、Stage IIIが18例(46.3%)で平均年齢12.1歳、Stage IVが13例(33.3%)で平均年齢12.7歳であった。受診動機は難聴を自ら訴えて受診したもの、難聴とめまいを自覚して受診したもの、健康診断で指摘されて受診したもの、たまたま耳鼻科を受診した折に指摘されたものなどに分けられるが、難聴を自覚する前に発見された群は手術年齢が若く、ステージの進行も軽いため、低侵襲な手術が可能であった。

We performed tympanoplasty on 39 patients with congenital cholesteatoma from September 1994 to November 2010. Using Potsic's staging system, we investigated the age of first examination, the reason for being examined, surgical procedure and auditory acuity at each stage of disease progression. There were 4 cases of stage I (10.2%), 4 cases of stage II (10.2%), 18 cases of stage III (46.3%), and 13 cases of stage IV (33.3%). The average age of the patients was 4 years at stage I, 5.2 years at stage II, 12.1 years at stage III and 12.7 years at stage IV. Their reasons for receiving otological examination included hearing impairment and the other than hearing impairment, such as vertigo, otitis media and otitis externa, and their congenital cholesteatoma was coincidentally identified. Minimally invasive surgery was possible because most of patients were young and mostly at stage I.
