Abstract

Objective:To analyze the clinical characteristics and prognosis,and to learn the impact factors of patients with sudden sensorineural hearing loss with contralateral sensorineural hearing loss(SSHLwCSHL).Method:Clinical data of 63 cases of patients with SSHLwCSHL were analyzed systematically,including all the clinical manifestations,audiologic characteristics and the effect assessment,and compared with that of unilateral sudden sensorineural hearing loss(USSHL) and bilateral sudden sensorineural hearing loss(BSSHL).Base on those,we summarized comprehensively the development and prognosis characteristics of the disease.Result:The incidence of SSHLwCSHL was 8.3 percent of overall patients with SSNHL.SSHLwCSHL occurs more commonly in male patients,with more vertigo,diabetes mellitus,and lipid panel abnormalities compared with other groups.Hearing curve and the degree of hearing loss of the prevalence ear of SSHLwCSHL was statistically significant difference with USSHL(P<0.05).Most common reason of the contralateral hearing loss was sudden sensorineural hearing loss(49%),and 59% patients of SSHLwCSHL suffered hearing loss of other ear after 2-10 years after contralateral hearing loss.The total effective rate was 14.3%,1 in 63 patients cured,1 excellence and 6 effective.The total effective rate was 9.5% in patients with severe or profound sensorineural hearing loss in the contralateral ear,which was lower than that of patients with moderate and moderately severe sensorineural hearing loss in the contralateral-ear(P=0.021).Conclusion:SSHLwCSHL has complex condition.The prognosis for improvement is poor.Recognition of similarities and differences between bilateral and unilateral SSNHL can help in counseling and managing the patients.
