VIN como predictor de nuevo ataque de vértigo en pacientes tratados con gentamicina intratimpánica

Abstract

Introduction and objective: Correlation between the values of slow-phase velocities of SVIN and the gain difference (healthy side – affected ear) in vHIT is described in the literature. On the other hand, we know that when intratympanic gentamicin is instilled, the gain is reduced during the first four weeks and that, in some cases, it increases, which predicts new attacks of vertigo. Method: A prospective longitudinal study was carried out in 88 patients with definitive Menière's disease who had been treated with intratympanic gentamicin. The patients were divided into two groups: Group A if the patient presented an attack of vertigo during follow-up; Group B if the vertigo attack did not occur during follow-up. Multiple variables were studied. Results: The slow phase velocity of nystagmus decreases in all patients of group A. No differences were observed in group B.
