[Sleep quality analysis in patients with unilateral idiopathic sudden sensorineural hearing loss]

Objective:To analyze the characteristics of sleep quality and its correlation with the clinical features and hearing curative effects in patients with unilateral idiopathic sudden sensorineural hearing loss (ISSHL). Method:Pittsburgh sleep quality index (PSQI) was applied to evaluate the sleep quality of unilateral ISSHL patients in our department. Patient group is divided into poor sleep quality subgroup (total PSQI score>7 points) and normal sleep subgroup (total PSQI score≤7 points). The differences of Patient group and two subgroups between hearing curative effect in the 30 days after treatment and sleep quality scores were compared and analyzed. Questionnaire survey was applied to control group, which contained 70 healthy people with normal hearing level and age matched. Result:A total of 75 cases were collected. To compare with control group, there were statistical difference in the scores of subjective sleep quality, habitual sleep efficiency, sleep disturbance and PSQI before treatment and in the score of habitual sleep efficiency after the treatment for 30 d (P<0.05). The sleep quality between poor sleep quality subgroup and normal sleep subgroup, total therapeutic effect after treatment for 30 d was no significant difference (P>0.05). The proportion for poor sleep quality were no statistically significant differences in the different efficacy of two subgroups (P>0.05). Two subgroups before treatment, in addition to sleep duration, there were statistically significant in all the sleep quality dimensions (P<0.05); after treatment for 30 d, in addition to subjective sleep quality, sleep duration, all have statistical difference (P<0.05). The poor sleep quality subgroup in the case group compared before and after treatment for 30 d, there was statistically significant in subjective sleep quality (P<0.05). The sleep disturbance before treatment, the sleep duration and PSQI scores after treatment for 30 d were associated with clinical features in patients with unilateral ISSHL (P<0.05). Conclusion:The sleep quality of patients with Unilateral SSNHL was significantly lower than that of normal hearing patients, the sleep quality had no significant effect on the general efficacy of unilateral SSNHL, but some sleep quality dimensions are associated with the clinical features before and after treatment.
