Cholesteatoma of the middle ear : Clinical study of 243 Cases 234例의 臨床硏究
Cho, Kyu Ja 中央醫學社 1941 中央醫學 Vol.10 No.5
Since Cruveilhier described the "pearly tumor" 1829 and Johannes Muller first used the term “cholesteatoma” in the medical literature (1838), the problem of cholesteatomatous otitis media has remained unsolved as far as etiology and pathogenesis are concerned, such as the neoplastic theory which has now only historical interest and the theory of metaplasia suggested by Wendt (1873) or the migration theory first proved by Habermann (1888). Also diagnosis and treatment still offer many problems. We have studied 243 ears with cholesteatoma proved by operation experienced during a 5 1/2 years period (Jan. 1959-July 1964) on the bases of incidence and symptoms with the purpose of contributing to the clinical diagnosis and treatment in the future.
