This book contains a new surgical technique for treatment of cholesteatoma developed by the author. It clearly states procedures, with many illustrations, to elucidate techniques for successful cholesteatoma operation. This title will be a valuable source to all those in the fields of otorhinolaryngology and audiology, and to surgeons and researchers concerned with cholesteatoma.
