The therapeutic effect of vitamins A and E in neurosensory hearing loss.

After an anatomical and physiological outline of the organ of Corti, the pathology of the cochlea related to the sensorineural deafness is described. The role of Vitamin A on cochlear function and the effects of Vitamin E in man are then emphasized, on the base of some experimental results. Clinical and therapeutic efficacy of the combination of Vitamin A + E is shown by a number of papers, pointing out a 5-15 decibel improvement of the pure-tone threshold in patients with sensorineural hearing-loss particularly when the auditory troubles are due to presbyaccusis.
