The are early diagnosis of acoustic neuroma is important for radical removal of it and for early radiologic diagnosis which was considered to be the most reliable method it is required to know the normal dimension of the internal auditory meatus. There are two methods for internal auditory meatal measurement; one is indirect, such as the conventional roentogenography, laminoraphy and cisternography and the other is direct using rubber cast method of Amjad, A.H. et. al. Authors measured the anatomical dimensions of Korean adult internal auditory meatus with regular rubberbase impression material.
