Item The Effect of Postmenopausal Osteoporosis on Middle Ear Resonance Frequency(2021) Baytaroglu, Berk; Jafarov, Sabuhi; Erbek, Selim Sermed; 35177390BACKGROUND: The effect of postmenopausal osteoporosis on the middle ear mechano-acoustic system is unknown. The aim of this study is to investigate whether or not middle ear resonance frequency is affected in females with postmenopausal osteoporosis. METHODS: The study included postmenopausal women aged 45-60 years, separated into 2 groups as females with postmenopausal osteoporosis and healthy postmenopausal females (control group). A detailed anamnesis was taken from all subjects and then the ear, nose, and throat examinations were done followed by pure tone audiometry, tympanometry, and multifrequency tympanometry tests. The groups were compared in respect of pure tone average, bone conduction threshold, RF, static admittance, and tympanometric peak pressure values. RESULTS: The mean age of the patients was 59.2 +/- 4.53 years (range, 48-65 years) in the postmenopausal osteoporosis group and 57.11 +/- 4.27 years (range, 48-65 years) in the control group (P>.05). The mean resonance frequency values for the postmenopausal osteoporosis and control group were 954.41 +/- 127.47 and 935.29 +/- 126.39 Hz (P>.05). The mean static admittance values for the postmenopausal osteoporosis and control group were 0.82 +/- 0.33 and 0.85 +/- 0.3 mmho, and mean tympanometric peak pressure values were -7.35 +/- 18.52 and -6.94 +/- 19.52 daPa (P>.05 for both static admittance and tympanometric peak pressure). The mean pure tone averagevalues for the postmenopausal osteoporosis and control group were 20.96 +/- 6.82 and 15.60 +/- 7.81 dB, and mean bone conduction threshold values were 17.57 +/- 6.03 and 12.10 +/- 6.52 dB (P<.05 for both pure tone average and bone conduction threshold). CONCLUSIONS: The results showed that the middle ear resonance frequency values were not affected in postmenopausal osteoporosis patients, but there was seen to be greater sensorineural hearing loss in females with postmenopausal osteoporosis compared to healthy postmenopausal females.Item Decrease in middle ear resonance frequency during pregnancy(2016) Dag, Emine Kutlu; Gulumser, Cagri; Erbek, Seyra; 27588163Many 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 audiometry and multifrequency tympanometry Pure-tone hearing levels at frequencies of 250 to 8000 Hz and resonance frequency values were corn pared between pregnant and nonpregnant women. Impact of age, side of the tested ear, and weight gained in pregnancy on resonance frequency were evaluated. Air conduction threshold values at frequencies of 250 Hz and 500 Hz were significantly higher in pregnant women than in the control group (P<0.001). Middle ear resonance frequency values of both ears in pregnant women were found to be significantly lower than those in control group (P<0.001). There was no statistically significant relation of middle ear resonance frequency values to age or side of the tested ear in both groups (P>0.05). A negative correlation between weight gained in pregnancy and middle ear resonance fre- quency values was determined for the left ear (correlation coefficient for left ears: 0.348, P=0.018). The results of this study suggest that resonance frequency may be decreased during the pregnancy. More comprehensive studies in which many pregnant women followed regularly before and after pregnancy are needed to have more certain links.
