Serum zinc level was measured in 88 patients with a sensorineural hearing loss and/or tinnitus and in 42 control group, and correlations between serum zinc level and the degree of sensorineural hearing loss or tinnitus were studied.
The average and standard deviation of serum zinc level in 79 patients with a sensorineural hearing loss was 0.831±0.184μg/ml and was significantly lower than that (0.951±0.156μg/ml) of the controls (p<0.01). But we were unable to find any statistical correlations between the degree of sensorineural hearing loss or types of audiograms and the serum zinc level.
The average and standard deviation of serum zinc level in 68 patients with tinnitus was 0.829±0.173μg/ml and was significantly lower than that of the control group (p<0.01). But it was impossible to find any statistical correlations between intensity of tinnitus and the serum zinc level.
We suggested that there were some correlations between serum zinc level and sensorineural hearing loss or tinnitus.
