examination, conductive hearing loss with normal bone
conduction curve by the aid of audiometry, an intact mobile
ossicular chain and a good eustachian tube function.
* operative data gathered during exploration of the middle
ear concerning the state of the ossicular chain, the state
of tympanic orifice of eustachian tube and the state of
