Sudden sensorineural hearing loss (SSNHL) is regarded as an otologic emergency of which bilateral involvement is rare and simultaneous bilateral involvement is very rare. In most cases the cause is idiopathic and in 30 to 65% of cases recovery happens spontaneously during two weeks period.
In this paper we present, a patient with simultaneous bilateral sudden deafness. After complete diagnostic assessment and standard treatment, she was candidated for cochlear implantation as the only remedy, after one year. But, after 15 month she suddenly noticed normal hearing in left ear. This was documented by paraclinical assessment.
This case is idiopathic with unfavourable prognosis and we couldn't find any similar report.
