Abstract


Diagnostic imaging methods are very important for patients with bilateral sensourinoural hearing loss. Magnetic resonance imaging (MRI) is able to demonstrate the vestibulocochlear nerve and facial nerve in the internal acoustic canal. Also computed tomography can be helpful to determination of the deficiency of the cochlear nerve. Cochlear nerve anomalies are classified into three group according to the magnetic resonance imagings.  Patients who have cochlear nerve deficiency may not hear with cochlear amplifications. Auditory brain stem implant (ABI) is most suitable for these cases. In this case report, we presented a 3 years old girls with bilateral totally hearing loss who performed cochlear implantation despite of cochlear nerve deficiency on magnetic resonance imaging (MRI) and computed tomography (CT).
