“…However, at low (250–2000 Hz) and high (4000–8000 Hz) frequencies, there was no significant difference between the hearing thresholds of the PCOS group and the control group. Our findings support other studies that also reported findings suggesting that EH frequencies which represent the basal end of the cochlea are often influenced sooner in disorders that cause endothelial and vascular damage [17,20,21]. In one other study, it was reported that chronic inflammation in PCOS could induce of hearing loss, particularly at EH frequencies [11].…”

BackgroundThe purpose of our study was to investigate the association between polycystic ovary syndrome (PCOS) and hearing thresholds.Material/MethodsForty women diagnosed with PCOS (mean age, 24.33±6.38 years) and 40 healthy women controls (mean age, 26.38±6.75 years) were included in prospective study. Each case was tested with low (250, 500, 1000, and 2000 Hz), high (4000, 6000, and 8000 Hz) and extended high (EH) (9000–20000 Hz) frequency audiometry. The fasting plasma glucose, insulin, FSH, LH, total testosterone, and sex hormone-binding globulin were measured in all patients.ResultsThe mean hearing thresholds at EH frequencies were statistically significantly higher in the PCOS group than in the control group (p=0.001 right ear and p=0.015 left ear). There were significant positive correlations among free testosterone index (FTI) values and hirsutism scores with EH frequency hearing thresholds.ConclusionsAt pure-tone audiometry (PTA) EH frequencies, we detected significantly higher hearing thresholds in PCOS patients than in controls. We also determined that elevated FTI and hirsutism score were positively correlated with elevated hearing thresholds in EH frequencies. These findings support that hyperandrogenism can play a role in the elevation of hearing thresholds in PCOS.

“…All of our histopathologic findings of cochlear and vestibular pathology in human temporal bones are supported by clinical studies of patients with otitis media. High-frequency sensorineural hearing loss secondary to COM has long been demonstrated (Costa et al, 2009; Paparella et al, 1984; Papp et al, 2003); more recent studies have shown sensorineural hearing loss, in regular or extended high frequencies, even in the earlier stages of otitis media, such as SOM and SPOM (Löppönen et al, 1992; Margolis et al, 2000; Sharma et al, 2012). In addition, it has been observed that patients who had SOM in childhood had a higher incidence of tinnitus in adulthood, as compared with control patients who did not have otitis media in childhood (Johnston et al, 2004; Mills and Cherry, 1984; van Cauwenberge et al, 1999).…”

Progression of changes in the sensorial elements of the cochlear and peripheral vestibular systems: The otitis media continuum

et al. 2017

Our study aimed to evaluate pathologic changes in the cochlear (inner and outer hair cells and stria vascularis) and vestibular (vestibular hair cells, dark, and transitional cells) sensorial elements in temporal bones from donors who had otitis media. We studied 40 temporal bones from such donors, which were categorized in serous otitis media (SOM), serous-purulent otitis media (SPOM), mucoid/mucoid-purulent otitis media (MOM/MPOM), and chronic otitis media (COM); control group comprised 10 nondiseased temporal bones. We found significant loss of inner and outer cochlear hair cells in the basal turn of the SPOM, MOM/MPOM and COM groups; significant loss of vestibular hair cells was observed in the MOM/MPOM and COM groups. All otitis media groups had smaller mean area of the stria vascularis in the basal turn of the cochlea when compared to controls. In conclusion, our study demonstrated more severe pathologic changes in the later stages of the continuum of otitis media (MOM/MPOM and COM). Those changes seem to progress from the basal turn of the cochlea (stria vascularis, then inner and outer hair cells) to the middle turn of the cochlea and to the saccule and utricle in the MOM/MPOM and COM stages.

“…Anatomic and physiologic knowledge of the auditory mechanism reveals that the frequency coding along the basilar membrane progresses from high to low frequencies with the distance from the basal end of the cochlea [ 15 ]. Taken together, these findings indicate that long-term listening to recorded music at high volume may result in harm to the high-frequency basal end of the cochlea, evident here as worse extended high-frequency hearing.…”

Is There a Relationship Between Obstructive Sleep Apnea (OSA) and Hearing Loss?

et al. 2016

BackgroundObstructive sleep apnea (OSA) is a common disorder with an estimated prevalence in the general population of 2–5%. Its main clinical features are loud snoring and breathing stoppage during sleep. Ischemia could be a consequence of noise-induced hearing loss because cochlear oxygen tension is reduced during and after noise exposure. In this study, we evaluated auditory function in patients affected by OSA and simple snoring.Material/MethodsA total of 66 participants (male to female ratio: 40:26) were included in the study, of which 21 were in the control group, 18 were in the simple snoring group, and 27 were in the OSA patient group. Polysomnography and audiometric examination were performed in all participants.ResultsThe mean ages of the participants in the control, simple snoring, and OSA groups were 39.14±9.9, 37.28±8.2, and 41.56±8.99 years, respectively. There were no statistically significant differences among groups regarding age or sex; however, there were statistically significant differences among groups in body mass index, apnea-hypopnea index scores, mean saturation, and duration under 90% saturation. In addition, statistically significant differences were found between the patient group and the control and simple snoring groups concerning the mean saturation, duration under 90% saturation, and the extended high frequency of hearing.ConclusionsThese data show that snoring may cause hearing loss at extended high frequencies.
