ryder is having trouble hearing in his right ear. he finds that he has to turn his head to hear with his left ear and often hears ringing or buzzing. How can a CT scan be used to diagnose this disease?

The error is clearly in his cochlea. His auditive left nerve is working (he hears buzzes), other components of the ear can be deemed unworking without CT. So we scan the cochlea and check out whether the cil cells work or it is the liquid.
