Audiograms of sudden sensorineural hearing loss (SSHL) were discussed in 82 cases with complete recovery and 27 with no improvement.
Results were summarized as follows:
1. The shape of the average audiogram of cases with complete recovery was bowl-shaped (all frequency affected) and of cases with no improvement was gradual sloping high tone loss.
2. The amount of hearing loss was additive with aging in the cases with complete rccovery, but not in cases with no improvement.
3. Strong similarities were found in the clinical pictures of the cases with complete recovery to the diuretic hearing loss.
4. It was suspected that the pathological process of SSHL with complete recovery may be in the stria vascularis.
5. The characteristics of acute strial hearing loss are: (i) sudden onset, (ii) complete recovery, (iii) bowl-shaped audiogram (all frequency affected) and (iv) additive hearing loss with aging.
