Transtympanic steroids for Ménière's disease.

OBJECTIVE: To describe the long-term efficacy of transtympanic steroids (TTS) using methyl-prednisolone in the treatment of Ménière's disease (MD).

DESIGN: Descriptive prospective study.

MAIN OUTCOME MEASURES: Pure-tone average (PTA) corresponding to the conversational frequencies on the audiogram (0.5, 1, 2, and 3 kHz), visual analog scale on tinnitus annoyance, and number of vertigo spells 24 months after treatment.

RESULTS: Thirty-four MD patients referred to a tertiary center were treated with TTS. All patients were diagnosed as probable or definitive MD (following American Academy of Otolaryngology-Head and Neck Surgery 1995 criteria) and treated by TTS (3 consecutive doses). Data from 32 patients were achieved after 12 months. Forty-eight percent of the patients reduced the PTA in 10 or more decibels, average improvement was 8.6 dB compared with initial PTA (p = 0.004). Tinnitus relief was achieved by 81.5% of the patients. Number of vertigo spells was reduced from 4.3 to 0.3 after 12 months (p = 0.002); 81% of the patients were free of vertigo spells, and 92.6% had 1 or less spells of vertigo. Data from 29 patients were achieved after 24 months. A reduction of PTA in 10 or more decibels was shown by the 33.3% of the sample, and PTA improved in 3.3 dB compared with initial PTA (nonsignificant). Tinnitus relief was achieved in 78% of the patients. Number of vertigo spells was reduced from 4.3 to 0.5 (p = 0.033). Seventy-eight percent of the cases were free of vertigo, and 96% had none or 1 spell. Because of an increase in any of the symptoms, 12 patients (35.2%) required retreatment with 1 or 2 series of TTS (1-3 doses) along the 2-year period. Two patients of the sample (6.25%) required transtympanic gentamicin for vertigo control due to lack of benefit with TTS (14 and 18 mo since TTS).

CONCLUSION: Transtympanic steroids in this cohort were associated with good preservation of hearing. Tinnitus control is achieved in more than 70% of the patients, and number of vertigo spells can be dramatically reduced in more than 90% of the patients after a 24-month follow-up.
