Abstract

OBJECTIVE:

To analyze the therapeutic effect of treatment for intermediate and high-frequency sudden sensorineural hearing loss (SSNHL).

METHODS:

A prospective clinical multicentre research was conducted using international standardized approach of clinical research. SSNHL Cases with intermediate and high-frequency hearing loss, that accepted no medication from onset of hearing loss within two weeks duration and ages ranged between 18 and 65, were collected. All patients were treated by one of four treatments plans chosen by unified random table.

RESULTS:

141 patients with intermediate and high-frequency SSNHL were recruited in the research. Twenty subjects were treated with lidocaine, 21 cases with lidocaine and hormone, 40 cases with Ginaton, and 60 cases with Ginaton and hormone. 42 out of 141 (29.79%) patients were total recovery, 24 (17.02%)achieved excellent recovery, 27 (19.15%)achieved partial recovery, and 48 (34.04%) were ineffective. The total effective rate was 65.96%. In lidocaine group, the total effective rate was 55.00%, 66.67% in lidocaine and hormone group, 67.50% in Ginaton group, and 68.33% in Ginaton and hormone group. Considering the total effective rate, there was no statistical difference between four groups (P > 0.05). However, the recovery rate in Ginaton group was significant difference comparing with that in lidocaine group (P = 0.0496). 119 had concomitant symptom of tinnitus, and the tinnitus was improved in patients of 81.51%. With regard to total effective rate of tinnitus in four treatment groups, it was 57.89% (11/19) in lidocaine group, 100.00% (18/18) in lidocaine and hormone group, 88.57% (31/35) in Ginaton group, 78.72% (37/47) in Ginaton and hormone group. There was significant ascendancy in lidocaine and hormone group versus that in lidocaine group (P = 0.002) and Ginaton and hormone group (P = 0.029). And the difference between lidocaine and Ginaton groups was statistical significance (χ(2) = 6.705, P < 0.05). In 43 patients with muffled symptom in aural region, 90.70% was partial recovery. There was no statistical difference between each groups (χ(2) = 5.97,P = 0.74). There were 17 with dizziness or vertigo improved in all cases. Another 10 patients accompanied other complaints all improved.

CONCLUSIONS:

for the treat of intermediate and high-frequency SSNHL, the therapeutic effect in hearing has no significantly different between single and combined drug therapies. Considering the recovery rate, there is an obvious advantage in Ginaton group compared with lidocaine group. Tinnitus is the major concomitant symptom in intermediate and high-frequency SSNHL, and lidocaine and hormone therapy should be used.
