OBJECTIVE: Intratympanic gentamicin is used to control dizziness of Ménière's disease, with a low rate of morbidity and a high success rate. We aimed to develop a new technique and schedule of therapy using a lower dose.
DESIGN: A retrospective chart review in Ménière's disease patients treated for intractable dizziness.
SETTING: A tertiary/quaternary care outpatient setting.
METHODS: Patients were administered intratympanic gentamicin using a low-dose protocol on 2 successive days and evaluated with pre- and post-treatment audiovestibular assessment.
MAIN OUTCOME MEASURES: Standard evaluation methods of audiovestibular function measured pre- and postfunction of hearing and balance to determine the effects of treatment and morbidity in the form of hearing loss. A telephone follow-up survey was also undertaken.
RESULTS: Patients reported satisfactory control of dizziness, with little morbidity in the form of hearing loss. We also found that the use of a myringotomy tube could be precluded. Post-treatment symptoms of imbalance reported by patients settled as patients compensated. In a telephone survey conducted some years after treatment, patient satisfaction was found to be high.
CONCLUSIONS: This two-dose regime was shown to be effective in controlling dizzy spells. In patients refractory to the initial two-dose treatment, a follow-up course of treatment usually proved effective. Long-term follow-up of patients seems to show that failure of treatment usually occurs within the first few months, and that symptoms, once controlled, rarely recur.
