Introduction During pregnancy virtually every organ system undergoes anatomical and physiological changes that can alter appreciably the criteria for diagnosis and treatment of diseases. Hormonal fluctuations alter the composition of endolymph and perilymph, and ion transport process. Hence, audiological functions in pregnancy need evaluation. Materials and methods After approval of Institutional Ethics Committee, 100 pregnant women were recruited in the 1st trimester. Tuning tests were done using 128, 256, 512, and 1024 Hz tuning forks. Pure tone audiometry was done and hearing thresholds measured for 125, 250, 500, 1000, 2000, and 4000 Hz. Finally, impedance audiometry was done in all the women in each trimester. Results There was no air—bone gap. There was gradual reduction in hearing acuity at low frequencies (125, 250, 500, and 1000 Hz) from 1st to 3rd trimester of pregnancy. The hearing thresholds got stabilized in the 3rd trimester and returned to normal in postpartum period. For 2000 Hz and higher frequencies, there was no significant difference in relation to pregnant subjects. Number of pregnancies did not affect the audiological functions. Conclusion Low-frequency hearing loss during pregnancy appears to be transient in nature with complete resolution in the postpartum period in most cases. For better understanding of these changes, obstetricians and otolaryngologists can team-up and avoid use of drugs for their symptoms during pregnancy.

Purpose: This study explores the changes in hearing thresholds in pregnancy. Materials and Methods: A prospective hospital-based observational study was performed with a total of 69 patients in the age-group of 18 to 40 years. Patients underwent hearing assessment twice during the study period. Conventional pure tone audiometry and impedance audiometry were performed, first during the antepartum period (28-32 weeks of gestational age) and second time during the postpartum period (6 weeks postpartum). Results: Significant difference was seen between the average of air conduction threshold values at speech frequencies when antepartum values were compared with postpartum values. Conclusion: The alterations in hearing sensitivity in pregnant females which improved during the postpartum period can be attributed to pregnancy.

Recent studies have identified sensorineural hearing loss as a possible manifestation of ankylosing spondylitis. We conducted a study of 30 patients with ankylosing spondylitis to characterize their audiologic profile and to correlate their disease activity and functional indices with their hearing thresholds. The study group was made up of 18 men and 12 women, aged 25 to 58 years (mean: 46.5), who were diagnosed with ankylosing spondylitis. We compared their findings with a socially and demographically matched group of 30 healthy controls. All 60 participants underwent an audiologic assessment, consisting of pure-tone audiometry, speech audiometry, and tympanometry. We used validated indices to assess disease activity and functional status, and we compiled information on the time of diagnosis and the types of medications used to treat the ankylosing spondylitis. We found that the average of the mean air-conduction thresholds at 0.5, 1, 2, and 4 kHz in the ankylosing spondylitis group was significantly worse than that of the controls (p = 0.004). A statistically significant difference was observed at frequencies greater than 3 kHz (p < 0.05). A subgroup of case patients who used only a tumor necrosis factor-alpha inhibitor exhibited better hearing thresholds than patients who used other drugs (p = 0.01). Differences in functional and disease activity scores between case patients with and without hearing loss were not statistically significant. We found that patients with ankylosing spondylitis did indeed have a greater prevalence of sensorineural hearing loss but that it was not correlated with either disease activity or functional status.

Background. Our study aimed to investigate an association between ocular pseudoexfoliation (PXF) and sensorineural hearing loss (SNHL) and to compare them with age and sex matched controls without pseudoexfoliation.Method. This was a case-control study of 123 patients which included 68 cases with PXF (at least one eye) and 55 controls without pseudoexfoliation. Pure-tone audiometry (PTA) was done for these patients at sound frequencies taken as important for speech comprehension, that is, 250 Hertz (Hz), 500 Hz, 1000 Hz, and 2000 Hz.Results. There were 41 patients with pseudoexfoliation syndrome (PXE) and 27 with pseudoexfoliative glaucoma (PXEG). The majority of patients with hearing loss (60%;n=51) were PXF patients and the remaining 40%(n=34)were controls. Below average hearing thresholds were significantly higher in the pseudoexfoliation group compared to the control group (P=0.01; odds ratio (OR), 3.00; 95% confidence interval (CI), 1.25–7.19). However, there was no significant difference in the mean hearing threshold levels between the three groups (PXE, PXEG, and controls) in either ear (ANOVA, right ear:P=0.46and left earP=0.36).Conclusion. Our study found an association between PXF and SNHL, confirming that PXF can involve organs in the body other than the eye.

Objective This study was performed to determine whether exposure to personal music players (PMPs) in the immediate morning prior to hearing testing confounds the association between mobile phone use and hearing thresholds of adolescents. Design In this cohort study of cognitive function in year 7 students (median age 13 years, range 11–14), information regarding the weekly use of mobile phones and the use of PMPs was assessed by a questionnaire. Pure-tone audiometry was used to establish hearing thresholds for all participants. Results Among a cohort of 317 adolescents (60.9% females), 130 were unexposed to PMP use while 33 were exposed to PMP use in the morning prior to hearing testing. No statistically significant difference in hearing threshold shifts was found between adolescents who were and were not exposed to PMP use prior to hearing testing. Likewise, the difference in the use of mobile phones according to the PMP use status was not statistically significant. Conclusion Exposure to PMPs prior to hearing testing did not introduce confounding in the present study of mobile phone use and hearing loss among adolescents.

OBJECTIVE: We speculate that the preoperative volume replacement with a convenient solution may protect the inner ear function after spinal anesthesia. METHODS: The patients were randomized in a single-blind fashion into two groups: group LR (n = 40) received lactated Ringer's and group GF (n = 40) received gelatin polysuccinate 4% (Gelofusine). Spinal anesthesia was performed with a 25 G Quincke needle and was given bupivacaine 0.5% 10 mg and fentanyl 25 jxg. Audio-grams were performed preoperatively and 2 days postoperatively. RESULTS: The overall incidence of hearing loss was 7.5%. The hearing loss was unilateral in two and bilateral in four patients. Hearing loss occurred within the low-frequency range and the hearing thresholds returned to normal by the fifth postoperative day. CONCLUSIONS: Although the incidence of hearing loss for the lactated Ringer's group was higher than the Gelofusine group, there was no statistically significant difference between the groups. For medicolegal and ethical reasons, patients should be informed about the possibility of hearing loss after spinal anesthesia.

Background: A prospective longitudinal multicentre study was conducted to assess the one-year postsurgical hearing preservation profile of the EVOTM electrode array. Methods: Fifteen adults presenting indications of electro-acoustic stimulation (pure-tone audiometry (PTA) thresholds ≤70 dB below 750 Hz) were implanted with the EVO™ electrode array. Hearing thresholds were collected at five time-points from CI activation to twelve months (12M) after activation. Hearing thresholds and hearing preservation profiles (HEARRING group classification) were assessed. Results: All subjects had measurable hearing thresholds at follow-up. No case of complete loss of hearing or minimal hearing preservation was reported at any time point. At activation (Nact = 15), five participants had complete hearing preservation, and ten participants had partial hearing preservation. At the 12M time point (N12m = 6), three participants had complete hearing preservation, and three participants had partial hearing preservation. Mean hearing loss at activation was 11 dB for full range PTA and 25 dB for PTAs low-frequency (125–500 Hz). Conclusions: This study provides the first longitudinal follow-up on associated hearing profiles to the EVO™ electrode array, which are comparable to the literature. However, other studies on larger populations should be performed.

Objective: We aimed to evaluate the prognostic factors for acute-onset tinnitus associated with unilateral idiopathic sudden sensorineural hearing loss (ISSNHL) and to assess the relationship between these factors and the final recovery. Methods: A total of 770 patients with unilateral ISSNHL were enrolled retrospectively and their medical records reviewed. Patients were classified into two groups according to the presence of acute-onset tinnitus at the initial examination. Patient characteristics and the results of pure-tone audiometry were compared between the two groups initially and 3 months later. Results: A total of 70.9% (n = 546) of patients had tinnitus initially. There was no significant difference in the mean hearing thresholds of the affected ear irrespective of accompanying tinnitus. In contrast, patients with tinnitus in the affected ear tended to have significantly better mean hearing thresholds in the nonaffected ear (p < 0.05). The logistic regression analysis revealed that better mean hearing thresholds in the nonaffected ear were associated with tinnitus occurrence (p < 0.05). Better hearing thresholds in the nonaffected ear, younger age, absence of dizziness, low-tone hearing loss, and combined intratympanic dexamethasone injection were associated with full recovery (p < 0.05). However, tinnitus was not an independent risk factor for full recovery. Conclusion: Better contralateral hearing was associated with both an increased incidence of concurrent tinnitus and a better final recovery. However, tinnitus was not related to full recovery.

The objective of this cross-sectional study is to compare bone-conducted low-frequency hearing thresholds (BClf) to cervical vestibular evoked myogenic potentials (cVEMPs) findings in prelingual adult deaf patients. The fifty participants (100 ears) included twenty healthy controls and thirty other subjects selected from patients who presented with bilateral prelingual deafness to Department of Audiology of Hamadan University of Medical Sciences and Health Services (Hamadan, Iran). Assessments comprised of audiological evaluations, cVEMPs, and computerized tomography scans. Twenty deaf patients (forty affected ears) with bilateral decreased vestibular excitability as detected by abnormal cVEMPs revealed that BClf hearing thresholds were completely absent. Ten deaf patients (twenty unaffected ears) with normal cVEMPs reported a sensation of the sound at BClf hearing thresholds (the mean for 250 Hz=41 dBHL and for 500 Hz=57.75 dBHL). Multiple comparisons of mean p 13 latencies, mean n23 latencies and peak-to-peak amplitudes between three groups were significant (P = 0.01 for all, one-way ANOVA test). Multiple Comparisons of mean BClf between three groups were significant (P = 0.00, One-way ANOVA test). Conclusion. Hypersensitivity of vestibular system to sound augments BClf hearing thresholds in deaf patients. The sensation of the sound at low frequencies may be present in patients with total deafness and normal vestibular function (predominantly saccule). This improvement disappears when saccular function is lost.

INTRODUCTION: Although tinnitus is an increasingly common symptom, few studies have assessed its prevalence or incidence among adolescents. PURPOSE: To assess whether the presence of tinnitus in adolescents is associated with minimal hearing damage, evaluated through high-frequency audiometry (HFA), otoacoustic emission (OAE), and loudness discomfort level (LDL). METHODS: The sample comprised 168 adolescents of a private school (61.3% boys; mean age 14.1 years old; standard deviation=2). All of them completed a questionnaire about tinnitus and hypersensitivity to sounds (sound intolerance), and then underwent otoscopy, pure-tone audiometry, HFA, LDL, transient and distortion product otoacoustic emissions (TOAE and DPOAE), and tinnitus pitch/loudness matching (the latter only in those with tinnitus). Participants were later divided into three groups: with no tinnitus (n=73, 43.4%), with sporadic tinnitus (n=47, 28%), and with constant tinnitus (n=48, 28.6%). RESULTS: No significant difference was observed between the groups regarding audiometry thresholds in frequencies from 0.25 to 16 kHz, or TOAE and DPOAE. However, the LDL in adolescents with constant tinnitus was significantly lower than that in other groups, suggesting hypersensitivity to sounds. CONCLUSION: There was no evidence of minimal hearing damage in the audiometry and OAE. Nonetheless, the decreased LDL in adolescents with constant tinnitus suggests that their auditory system is more sensitive. Therefore, this may be the first sign of vulnerability to sounds. Future medium- to long-term monitoring of these students may show whether they will begin a process of functional impairment, altering hearing thresholds, and OAE.
