|Official Title:||Effectiveness of Transtympanic Steroids in Unilateral Ménière's Disease: a Randomised Controlled Double-Blind Trial|
|Study Start Date :||April 2009|

|Experimental: Steroid (Methylprednisolone)||
2 transtympanic injections at interval of two weeks.
|Active Comparator: Gentamicin||
2 transtympanic injections at an interval of two weeks. If there is significant hearing loss before second injection, it will be replaced by normal saline in double blinded fashion.
- Vertigo Attacks [ Time Frame: 6month pre-enrollment baseline, 18-24 months after initial treatment ]The number of vertigo attacks between 18-24months follow-up were taken retrospectively during a face-to-face appointment at 24 months follow-up and compared to 6 month pre-enrollment baseline (as per Committee on Hearing and Equilibrium guidelines).
- Change in Hearing [ Time Frame: Baseline, 1,2,6,12,18 and 24months after initial treatment ]Hearing was measured as ipsilesional pure-tone threshold at Baseline, 1month, 2months, 6months, 12month, 18months and 24 months follow-up. Hearing level was taken as the average threshold across 0.5, 1, 2 and 3KHz.
- Change in Speech Discrimination [ Time Frame: Baseline, 1,2,6,12 and 24months after initial treatment ]
Speech discrimination was measured at Baseline, 1month, 2months, 6months, 12month and 24 months follow-up.
Speech discrimination was assessed by means of ipsilesional suprathreshold word recognition (%). Arthur Boothroyd's isophonemic word lists (AB wordlists, Guymark, Southampton) comprising sets of 10 words were played to the ipsilesional ear at the low-frequency pure-tone threshold of 0·5, 1 and 2 kHz +30dB with masking sound in the contralesional ear if necessary. The formula for masking level was: low-frequency pure-tone threshold in ipsilesional ear - bone conduction mean threshold (0·5, 1 and 2KHz) in contralesional ear - 40dB. Speech loudness and masking were rounded to the nearest 5dB. Step increments and decrements of 10dB for speech loudness and masking were used to attain the maximum speech discrimination score.
