Sensorineural deafness

Explanation:

The organ of Corti is also knowns as the spiral organ.It is the organ used for hearing and it is very receptive.It is located in the mammalian cochlea and it is the most likely organ to be affected in this case. The proximal end of the organ of Corti, close to the oval window is the affected part.
