Abstract：Objective To analyze clinical characteristics and misdiagnosed causes of sudden deafness.Methods Clinical data of 8 misdiagnosed patients with sudden deafness admitted between January 2013 and January 2015 was retrospectively analyzed.Results All the 8 patients visited doctors for vertigo and tinnitus,among whom 3 patients had complicated with visual rotation,2 patients with nausea,6 patients with persistent hearing decline,5 patients with sudden deafness and 3 patients with deafness and tinnitus at the same time.All patients were misdiagnosed at the first diagnosis,and misdiagnosed time was 3-15d.Among them,4 patients were misdiagnosed as having staggers,2 patients as Meniere's disease and 2 patients as vertebrobasilar insufficiency.Listening examination showed that 6 patients with high frequency descent type and 2 patients with full frequency descent type in audiometric curve.Tuning fork test showed that moderate sensorineural hearing loss was found in 1 patient,and severe sensorineural hearing loss in 7 patients.Acoustic immittance measurement showed decreased stapedius reflex threshold value in 6 patients,and 2 patients had cochlear impairment by otoacoustic emission and cochlea point diagram.Vestibular function was normal in 2 patients,decreased in 3 patients and disappeared in 3 patients.All patients were confirmed as having sudden deafness,and were treated with glucocorticoid,thrombolysis,anticoagulation drugs,neurotrophic drugs and hyperbaric oxygen therapy.All patients were cured and discharged after hearing had been returned to normal by treatments.Conclusion Clinical symptoms of sudden deafness are non-specific.Clinicians should improve cognition and diagnosis of the disease,and give related examinations in time to avoid misdiagnosis and mistreatment.
