The cases with sensorineural hearing loss from 1978 to 1980 were reported. The cases content: sudden deafness 37 cases, fluctuating hearing loss 6 cases, progressive hearing loss 6 cases, unilateral hearing loss 65 cases, sensorineural hearing loss with internal diseases 328 cases.
In the cases with internal diseases, we could trace 94 cases during 1-3 years, and they were classified following items of the group of internal diseases, age, sex, degree and type of hearing loss. The group of internal diseases contained central nervous system, respiratory, digestive, cardiovascular and renal, hematogenous, endocrine and immune diseases.
So we have not enough cases, we couldn't detect any correlation between the changes of the internal diseases and sensorineural hearing loss. The further studies should be required.
