To analyze characteristics and curative effect of sudden sensorineural hearing loss (SSHL) inpatients with different audiometric curve and provide the reference for the diagnosis and treatment of SSHL.

Retrospective analyze of 1033 cases of SSHL inpatients, compare the gender, the ears, the ages, with or without tinnitus and vertigo, hearing loss degree and the efficacy of distribution characteristics in different audiometric curves.

Lnpatients with SSHL are mostly flat (27.24%), peak valley at least (5.94%); Gender distribution: male to female ratio was 1.3:1, audiometric curve for the rise type more than the decline type and flat type and completely deafness type (P < 0.01) in female. The ears distribution: the flat type more than increase type ( P < 0.01) in double eras SSHL. The age distribution: the flat type more than 60 years of age was significantly higher than that rising type (P < 0.01). Completely deafness type compared with the other types, the decline type compared with the rise type, the incidence of vertigo was significantly different (P < 0.01). Peak valley type with tinnitus was higher than the flat type. Degree of hearing loss distribution: completely deaf type in the very severe hearing loss was significantly higher than other types (< 0.01), flat type in severe hearing loss was significantly higher than other types (P < 0.01). The total effective rate was 51.01%. Rise type, peak valley type were more efficient than other types (P < 0.01); completely deafness type was less efficient than other types (P < 0.01).

The characteristics and curative effect are different in SSHL inpatients with different audiometric curves. Flat type was the most, peak valley type was the least. The curative effect of rise type and peak valley type are the best, completely deafness type is the worst. The degree of hearing loss and whether associated with vertigo is closely related in efficacy.
