Sensorineural hearing loss with delayed onset of vertigo.
Sensorineural hearing loss with delayed onset of vertigo is a syndrome in which episodic vertigo arises in a person who has preexisting unilateral severe-to-profound sensorineural hearing loss. This syndrome has an ipsilateral form in which the vertigo arises from the poorer hearing ear and a contralateral form in which the aural symptoms arise from the better hearing ear. The existence of this syndrome has only been noted within the past two decades. This report details our clinical experience with 17 persons with the ipsilateral form of this disorder. The onset of the vertigo after the occurrence of the hearing loss was quite variable. It ranged from 1 to 60 years after the development of the hearing loss. The hearing loss occurred for several reasons. Most patients had hearing loss due to an unknown cause. The development of the vertigo and the timing of the onset of the vertigo were not related to the cause of the hearing loss. Bithermal caloric testing identified the offending labyrinth in most patients who underwent ablative vestibular surgery. Ablative vestibular surgery was performed in 13 of the 17 persons in this study because of disabling symptoms. In all 13 cases, the episodic vertigo was eliminated. Surgical treatment for sensorineural hearing loss with delayed-onset vertigo, as with all surgery for vertigo, should be based on the severity of the afflicted person's symptoms.
