Cochlear otosclerosis and perilymphatic fistulas deservedly received considerable attention during 1966 and 1967. Although definite progress was made towards a better understanding of these entities, many basic questions remain unanswered. Granuloma formation in the oval window following stapes surgery, the fixed malleus syndrome, the choice of seal for the oval window, and causes of sensorineural loss following stapedectomy were studied. A number of interesting and informative long-term evaluations of stapes surgery appeared in the literature. Various reports clarified different clinical aspects of otosclerosis, eg, vertigo and tinnitus. Several attempts were made to define preoperatively the extent and location of the otosclerotic focus. Unfortunately, little was added to our knowledge of the etiology, histopathology, and biochemistry of this baffling process.
How often does cochlear otosclerosis cause sensorineural hearing loss? When it does, what are the pathological alterations responsible for the loss? Is any treatment possible? The 99th meeting of
