The aim of our study was to obtain wideband tympanometry (WBT) findings in Meniere's disease (MD). It also aimed to evaluate whether the data obtained have diagnostic significance. 21 patients who were followed-up for unilateral Meniere's Disease were evaluated. The ears with Meniere disease were grouped as the MD group and the opposite ears were grouped as the control group. WBT results were recorded as resonance frequency (RF) and frequency-specific absorbance values at 10 different frequencies in the 0.25-8.0 kHz range. Statistical analysis was performed with t test and receiver-operating characteristic analysis. Considering the WBT results, RF was significantly lower in the MD group compared to the control group (p < 0.001). Frequency-specific absorbance values at 0.25, 0.5, 0.75 and 1 kHz were significantly lower in the MD group compared to the control group (p < 0.05). No significant difference was found at 1.5 kHz and above (p > 0.05). For the MD, the RF below 598 Hz was 85.7% sensitive and 76.2% specific, the absorbance at 0.25 kHz below 8% was 66.7% sensitive and 61.9% specific, the absorbance below 17% at 0.5 kHz was 71.4% sensitive and 62.1% specific, the absorbance below 36% at 0.75 kHz was 81% sensitive and 57.8% specific, and the absorbance below 46% at 1 kHz was 71.5% sensitive and 66.7% specific. When MD was compared with intact ears, it was observed that RF was lower, and absorbance decreased in low frequencies. These data is statistically significant, but the sensitivity level is not enough for diagnostic use. Therefore, it is considered as an complementary test for the diagnosis.
