Laberintectomía química:protocolo y resultados

Resumo

We present a prospective study about 10 cases of unilateral incapacitate Meniere Disease (clinical stage II and III), without response at medical treatment during at less one year, with a minimal follow-up of 6 months. We employed injection of buffered gentamicin solution weekly. In 5 patients we add a ventilation tube (VT). Medium of dosage utilised was 3.4 (range = 2- 5). No significant hearing loss and initial oscillopsia was present in any patients, but days after two cases developed transitory oscillopsia. A case of Otorrea occurs in a VT receptor. In nine patients initial control of vertigo was achieved. Average time of stabilisation was 26.89 days (range = 13- 45). We found vertigo recurrence in 3 cases. Average of recurrence presentation was 6.33 months (range = 4-9). Chemical laberintectomy with gentamicin is a therapeutic alternative in the treatment of selected cases of unilateral incapacitate Meniere Disease. Results in VT recipient are similar that patients without no VT.
