• Influence of otitis media upon cochlear function

抄録

Influence of otitis media upon the cochlear function was examined clinically on patients with severaltypes of otitis media, and the following findings were obtained.<BR>1. In otitis media with effusion, abnormality in the bone conduction probably due to middle ear negativepressure and/or fluid retention was observed at least in 30% of children, but actual sensorineural hearingloss was revealed as rare as approximately 3%. Cases whose mean bone conduction threshold was worsethan 20 dB even after myringotomy and removal of effusion were revealed high-risk cases in terms of permanentsensorineural hearing loss.<BR>2. In chronic non-cholesteatomatous otitis, sensorineural hearing loss tended to progress more than that byaging particularly in aged population.<BR>3. Sensorineural hearing loss was found to progress with the length of disease course also in primary cholesterolgranuloma of the middle ear, and its treatment including steroid (P.O.) and tympanostomy tubeinsertion was found to be effective particularly in young patients. It seems, therefore, desirable to treatthis disease as early as possible.<BR>4. Worsening of the bone conduction hearing often observed in acute otitis media or mastoiditis cannot necessarilybe considered as the cochlear sensorineural damage, because it is often reversible and alsobecause loss of vestibular function is not often observed. We tried to test our hypothesis that this boneconduction worsening may be caused by mechanical impairment of sound conduction through the temporalbone due to fluid retained in the mastoid and middle ear using a dry human temporal bone, but failedto demonstrate it.
