Abstract: Objective To explore the value of the pure-tone audiometry in auditory function screening among the impaired glucose regulation(IGR) patients. Methods ①Thirty IGR patients without the symptoms of deafness and 30 controls were enrolled in the study. Pure tone audiometry and tympanometry were tested (evaluated). Results The prevalence rate of hearing loss was higher in the IGR group (33.67%) than that in the control group (10%, P<0.05). ②As compared with the control group, the hearing threshold at each frequency in the IGR group was higher, but there were statistically significant differences only at 4 000 and 8 000 Hz (P=0.008, P=0.003). ③Eleven cases in the IGR group had the symptoms of tinnitus, and among them 3 cases had hearing loss. There was no significant difference in the prevalence rate of hearing loss between the cases with hearing loss and those without hearing loss in IGR group (P=0.466). Conclusion The prevalence rate of hearing loss in patients with IGR was significantly increased, and high-frequency hearing loss was more profound. Hearing loss in IGR may occur before the symptom of deafness.
