“…Also, MD patients compared to controls revealed a decrease in the RF [Franco-Vidal et al, 2005;Lilly, 1984]. Study findings were validated as Franco-Vidal et al demonstrated a reproducible increase of the inner ear pressure in normal subjects (by body tilts, Trendelenburg) with a concomitant increase of the G width [Franco-Vidal et al, 2015]. However, body tilt increased the RF.…”

Introduction: Diagnosing Ménière’s disease (MD) by its characteristics such as episodes of vertigo, fluctuating hearing loss, and tinnitus with aural fullness remains challenging. Available tests evaluating the presence of endolymphatic hydrops (EH) are often expensive or time assuming. An in-office quick and simple non-invasive diagnostic test is multifrequency tympanometry (MFT). It can measure conductance at 2 kHz probe tones, which was demonstrated to reflect variations in cochlear pressure. Previous studies investigating MFT as a diagnostic test for MD showed conflicting outcomes possibly biased by their retrospective design. Methods: We prospectively collected MFT results (Y width) in patients with dizziness and compared MFT test results in affected (group 1) and unaffected (group 2) ears of 37 MD subjects and in control ears of 33 non-MD subjects (group 3). Results: The mean value of the Y width in affected ears was 315.6 ± 70.2 daPa compared to 292.3 ± 98.6 daPa in unaffected ears in MD subjects and 259.4. ± 60.6 daPa in the non-MD group. A positive test result (i.e., a Y width of 235 daPa or more) was found in 35 ears in the MD group, 21 times involving the affected ear and 14 times involving the unaffected ear, compared to 16 in the non-MD group. No significant differences between the three groups could be demonstrated (p > 0.05). We found a sensitivity of 58.3% and specificity of 66.3% for detecting EH in an affected ear in MD subjects. Conclusion: There is a trend towards increased conductance tympanometry in affected ears. However, we noticed a high false positive rate of MFT and do not support standardized use of MFT as an additional diagnostic tool for detecting EH in MD patients. A negative test result on the contrary is unlikely related to EH.

“…Franco-Vidal et al [21] conducted multifrequency tympanometry for the Trendelenburg position and found the RF to be high. Although they could not give the exact reason for this, they suggested that there might be tension in the annular ligament due to the mass effect of increased inner-ear pressure generated by the position.…”

Introduction: The effect of the continuous forced expiration action of players of wind instruments to produce sound, on the eustachian tube functions and the middle-ear resonance frequency (RF), has not been investigated in the literature to date. The aim of this study is to evaluate eustachian tube functions and the middle-ear RF of players of wind instruments. Methods: In this prospective case-control clinical study, a study group of 28 players of wind instruments in the orchestra (28 participants, 56 ears) and a control group of 34 volunteers (34 participants, 68 ears) were included. The eustachian function of wind instrument players in a symphony orchestra was measured using an automatic eustachian tube function test in acoustic tympanometry and the RF of the middle ear was determined in multifrequency tympanometry. Results: There was a statistically significant difference among the musicians, especially in players of woodwind instruments, in terms of dysfunction of the eustachian tubes (p = 0.048). In the musicians, the pre- and postperformance RF mean values for all ears were 925 and 1,020 Hz, respectively, and these were significantly different (p = 0.004). Conclusion: This is the first study to uses multifrequency tympanometry to examine the middle-ear RF and eustachian tube function of wind instrument musicians in an orchestra. Eustachian tube dysfunction was found to be more prominent and a higher RF of the middle ear was seen after a performance, especially in players of wood wind instruments. However, the effect of these on the professional performance of players of wind instruments should be investigated in future work.
