The effect of body mass index on traditional 226 Hz tympanometry and wideband tympanometry test results

Objectives: The aim of this study was to investigate the possible effects of body mass index BMI on traditional 226 Hz tympanometry and wideband tympanometry WBT to gain a better understanding of resonance frequency. Patients and Methods: A total of 158 ears of 79 volunteers 19 males, 60 females; mean age: 20.5 years; range, 18 to 27 years who had normal hearing and normal otoscopic examination findings were included in the study between October 2019 and June 2020. By measuring the weight and height of the participants, their BMI values were classified into three groups: ≤18.5 kg/m2 underweight , 18.5 to 24.9 kg/m2 normal weight , and ≥25.0 kg/m2 overweight . Tympanometric evaluations were conducted using the Interacoustics-Titan WBT. Results: The difference of ear canal volume ECV was significant between the two sexes p0.05 . A significant difference was found in the ECV and resonance frequency among the three BMI groups p
