Abstract
-
BACKGROUND AND OBJECTIVES: Several treatment options have been introduced to control Meniere's disease (MD). Among them, intratympanic injection of gentamicin (ITGM) is now accepted as a standard treatment method for intractable vertigo in patients with hearing impaired MD. The purpose of this study was to analyze the clinical course and treatment flow in patients with MD and to analyze the efficacy and problems after ITGM.
SUBJECTS AND METHOD
A retrospective study was performed on 458 patients who were diagnosed as definite MD from May 2003 to October 2007 and were followed up at least 1 year. The authors investigated the course of disease and the results in our patients according to the treatment options. Several clinical parameters including frequency of vertigo, audiometry, caloric and rotation test were reviewed and analyzed according to the guideline of the AAO-HNS (1995), if necessary. Efficacy and problems after ITGM were reviewed.
RESULTS
Among 458 patients, vertigo was resolved or improved in 399 patients (87.1%) with medical management. Fifty-nine patients needed further treatment (endolymphatic sac decompression: 4, Meniette: 2, ITGM: 53). Among 53 patients who got ITGM, 40 patients were followed up for more than 1 year after injection. Thirty-six patients (87.5%) showed successful control of vertigo. The average pure-tone threshold was changed from 54.1 dB to 56.9 dB after treatment. Three patients (7.5%) revealed more than 20 dB aggravation.
CONCLUSION
Vertigo was controlled by supportive treatments or medication in 87% of definite MD patients. And ITGM could effectively and reasonably control vertigo for intractable MD patients.
