sensorineural deafness

Quick Reference

Any form of deafness in which sound is conducted normally through the external and middle ears but hearing loss occurs as a result of disease or damage in the cochlea or the neural pathway from it to the brain. Its most common forms are presbyacusis (high-frequency hearing loss in old people resulting from deterioration of the organ of Corti), occupational deafness caused by exposure to noise at work, ototoxic deafness following excessive intake of drugs such as quinine or aspirin, infectious deafness from mumps or congenital rubella (German measles) leading to destruction of the cochlea, and a tumour on a nerve supplying the vestibular system. Also called nerve deafness. See also decibel. Compare central auditory processing disorder, conductive deafness. [From Latin sensorius of the senses, from sensus felt, from sentire to feel + Greek neuron a nerve + -al from -alis of or relating to]
