[Clinical characteristics and prognostic analysis of sudden sensorineural hearing loss with metabolic syndrome]

Objective:To analyze the clinical characteristics and prognosis of sudden sensorineural hearing loss (SSNHL) with metabolic syndrome (MetS).Method:Records of 212 patients with SSNHL treated in our department were retrospectively reviewed, including gender, age,course of the disease, concomitant time of tinnitus and vertigo, concomitant rate of hypertension and diabetes mellitus, BMI, systolic pressure, diastolic pressure, HDL-C, TG, fasting plasma glucose level, severity of hearing loss and audiograms. All patients were divided into two groups, the MetS group and the Non-MetS group, and the clinical characteristics and prognosis between two groups were compared.Result:In the MetS group, the BMI, systolic pressure, TG, fasting plasma glucose level were higher than that in the Non-MetS group, while the HDL-C level was lower than that in Non-MetS group (P<0.01), and the rates of profound hearing loss, flat audiogram and total deafness audiogram were higher than that in the Non-MetS group (P<0.05). In the MetS group, the overall recovery rate, complete recovery rate and marked recovery rate were 57.8%,6.0% and 14.5%, respectively, which was lower than that in the Non-MetS group (79.8%,19.4% and 27.9%, P<0.05 ).Conclusion:SSNHL patients with MetS suffered a severer hearing loss, the most audiograms were flat and total deafness, and the prognosis of SSNHL patients with MetS was poorer.
