Decrease in Middle Ear Resonance Frequency During Pregnancy
Many physiological changes occur during pregnancy. The aim of the study was to reveal whether there is a change in middle ear resonance frequency during pregnancy. A prospective case-control study was designed at a tertiary referral center. The study included 46 pregnant women at the third trimester (27-40 weeks) and 43 nonpregnant voluntary women. All the study subjects underwent pure-tone aud...
متن کاملEffect of Body Mass Index on Middle Ear Resonance Frequency.
OBJECTIVE Multifrequency tympanometry (MFT) analyzes tympanograms obtained using different probe tones between 226 and 2000 Hz. An important parameter of MFT is resonance frequency (RF). Studies have recently demonstrated that the RF value can vary depending on many factors. To provide new data regarding MFT, middle ear RF values were investigated with regard to body mass index (BMI). MATERIA...
متن کاملAging and middle ear resonance.
Tympanograms for probes ranging from 250 through 2000 Hz were evaluated for 467 older adults. Measures of middle ear resonant frequency were compared across age groups (48-59, 60-69, 70-79, 80-90 years) and gender. No significant age group trends were observed for middle ear resonant frequency. Middle ear resonant frequencies were significantly higher for older women than for older men, but the...
متن کاملMiddle ear resonance in infants: Age effects
INTRODUCTION The resonant frequency is the probe frequency in which susceptance is 0 due to the neutralization of the forces of mass and stiffness components that control the middle ear. This frequency can be evaluated by multifrequency tympanometry, and the normality value for adults ranges 800-1,200 Hz. Studies about resonant frequency in children are scarce. AIM Identify the variation of...
متن کامل[Normative values of middle ear resonance frequency in normal hearing adults].
OBJECTIVES This study aims to determine the normative values of middle ear resonance frequency in healthy adults. PATIENTS AND METHODS Sixty adult volunteers (32 females, 28 males; mean age 31.8±7.1 years; range 21 to 46 years) with normal otoscopic examination, audiometry and electroacoustic immitancemetry findings were enrolled in the study. The middle ear resonance frequencies were calcula...
