title: Isolated deafness in multiple sclerosis patients.
abstract: Isolated cranial nerve involvement in multiple sclerosis (MS) patients is not frequent. Deafness is considered to be uncommon in MS patients. We have reviewed the sensorineural hearing loss episodes that had been thoroughly investigated in our hospital in the last 5 years. We present three cases of sensorineural hearing loss in patients with MS and compare them with other previously reported and discuss this uncommon symptom. The cases that we present were firstly evaluated by an otolaryngologist. A lesion is seen at the root-entry zone of the eighth cranial nerve in only one case, but no lesions are seen in the other cases. A retrocochlear demyelinating disorder was demonstrated in the two patients in whom brainstem auditory evoked potentials were performed. All patients recovered at least partially their hearing functions.
