The association of otosclerosis with reduced bone conduction is well known but no experimental or valid clinical relationship has been established to confirm this relationship. The purpose of this presentation is to demonstrate a clinical relationship between otosclerosis and sensorineural hearing loss. Experimental proof will await the accumulation and study of temporal bones of those individuals who, in life, exhibited the clinical relationship to be developed in this dissertation.
The material presented is from the author's private practice during the years 1974, 1975 and 1976. Patients presenting the clinical problem of progressive sensorineural hearing loss were examined in depth including diagnostic audiology and polytomography of the petrosa.
This thesis shows that a high percentage of such diagnostic problems are due to cochlear otosclerosis, the diagnosis being clinically supported roentgenologically.
