[Treatment of sensorineural hearing loss with delayed onset of vertigo (report of 13 cases)].
Sensorineural hearing loss with delayed onset of vertigo (SHL-DV) is a syndrome consisting of preexisting SHL and subsequent episodes of vertigo. The possible underlying pathophysiology is delayed endolymphatic hydrops. This paper details our clinical experience with 8 patients with SHL-DV caused by otitis media and 6 patients following sudden deafness and hearing loss due to an unknown cause. The average period of onset of vertigo after the occurance of the hearing loss was 22.6 years. The average period of vertigo was 6.2 years. Surgical treatment was performed in 13 patients (14 ears) because of disabling vertigo. Endolymphatic sac decompression was performed in 2 ears, transmastoid labyrinthectomy in 3 ears, gentamycin perfusion of the tympanic cleft in 3 ears, streptomycin perfusion of the labyrinth in 6 ears. Follow-up for 13 patients who had surgery averaged 2.3 years, all patients were cured of their episodic vertigo. Three patients underwent surgical labyrinthectomy suffering with total hearing loss, but aminoglycoside antibiotics induced labyrinthectomy preserving some hearing. We conclude that chemical labyrinthectomy is the therapy of choice for the severe SHL-DV who has serviceable hearing.
