ObjectiveBoth large vestibular aqueduct syndrome (LVAS) and high jugular bulb (HJB) are regarded as abnormalities commonly seen on the temporal bone CT. High jugular bulb has been found to erode the vestibular aqueduct, and there are several studies on jugular bulb vestibular aqueduct dehiscence. However, there is no study that specifically reports LVAS with concurrent HJB and its hearing loss relatedness. This study presents the pure tone audiometry differences between LVAS with HJB, and LVAS without HJB.MethodsThis was a case control study involving 36 bilateral LVAS with concurrent unilateral HJB patients, total of 72 ears. Intra-person comparison was done, by dividing ears into two groups: the case group, 36 ears (LVAS with HJB); and the control group, 36 ears (LVAS without HJB). Air conduction thresholds (250–4000 Hz), bone conduction thresholds (250–1000 Hz), and air bone gap (250–1000 Hz) were analyzed and compared between groups.ResultThere were statistically significant differences in AC thresholds at 250, 500, 2000, and 4000 Hz between the groups, p < 0.05. But there was no statistical significant difference at 1000 Hz, p > 0.05. There were statistical significant differences in BC thresholds at 250 and 500 Hz, p < 0.05, but there was no statistical difference at 1000 Hz. There were no significant differences in air bone gap at 250, 500, and 1000 Hz between the two groups.ConclusionLVAS with concurrent HJB was found to have higher air conduction thresholds, especially at 250, 500, 2000, and 4000 Hz. Bone conduction thresholds were higher at 250 and 500 Hz. Air bone gap at 250, 500, and 1000 Hz, were not significantly higher in LVAS with concurrent HJB.

<p class="BodyA"><strong>Background: </strong>COVID-19 pandemic is caused by SARS CoV2. The last reference of pandemic was Spanish flu in 1918 which caused hearing loss in many patients. The effect of COVID-19 is an interesting issue in audiology. Not much studies have been done; therefore, this kindled our interest to have a study on audiological profile of asymptomatic COVID-19 patients.<strong></strong></p><p class="BodyA"><strong>Methods:</strong> The 20 cases in the age group of 20 and 50 years who were confirmed positive for COVID-19 formed the study group. 20 subjects who had normal hearing (Audiometric threshold at or better than 15 db HL) were used as control group. Pure-tone audiometry (PTA) was done for both the group on day 7 and 30. Air conduction and Bone conduction were measured. The audiometric thresholds were measured using the modified Hughson-Westlake method.</p><p class="BodyA"><strong>Results:</strong> High frequency hearing impairment was found in 9 out of 20 patients in the study group on day 7. Out of the 9 affected patients 7 patients showed improvement upon further testing done on day 30.</p><p class="BodyA"><strong>Conclusions: </strong>Like anosmia and ageusia, hearing loss can be considered as one of the clinical features in COVID-19 patients. This study was recorded to find a significant hearing loss in asymptomatic COVID-19 patients and thus sheds light on the auditory problem that people are experiencing during these difficult times and for future reference on pandemic research.</p>

Introduction The bone-anchored hearing aid (BAHA) is a bone conduction system that transmits the sound directly to the inner ear by surpassing the skin impedance and the subcutaneous tissue. It is indicated for patients with mixed, conductive and unilateral sensorineural hearing loss who did not benefit from conventional hearing aids (HAs). Although the benefits from BAHA are well demonstrated internationally, this field still lacks studies in Brazil. Objective To assess the auditory rehabilitation process in BAHA users through audiological, speech perception and tinnitus aspects. Methods Individuals with hearing loss were assessed before and after the implantation. The participants were subjected to pure tone audiometry in free field, functional gain audiometry, speech perception tests, tinnitus handicap inventory (THI) in open format, and to the visual analog scale (VAS). Results It was found that the participants benefited from the use of BAHA. The difference in the performance of the participants before and after the BAHA surgery was significant in terms of hearing acuity. There was no statistically significant difference in the speech perception tests. The tinnitus assessment showed that 80% of the participants scored slight tinnitus severity in THI after using a BAHA. Eighty percent of the participants classified their tinnitus as absent to mild in the VAS after the surgery. Conclusion Based on the results of the current study, we can conclude that the participants improved both the auditory perception and the tinnitus handicap.

AbstractFifty-six individuals with acromegaly referred for pituitary surgery were studied to determine any relationship between acromegaly and sensorineural or conductive hearing loss. Compared to a matched population control sample, no significant difference between the acromegalics and controls has been found, either for air conduction or for bone conduction. The differences between these findings and those published previously are discussed, and reasons proposed to explain the discrepancies.

PURPOSE: This study aimed to correlate probable predisposing factors for sensorineural hearing loss in elderly by investigating the audiologic characteristics and frequency of mutations in genes considered responsible for non-syndromic hearing loss. METHODS: Sixty elderly patients were separated into two groups: the Case Group, composed of 30 individuals, 21 females and nine males, all 60 years old or older and presenting diagnoses of sensorineural hearing loss, and the Control Group, composed of 30 elderly individuals matched to the experimental group by age and gender, presenting normal hearing. The patients underwent anamnesis and pure tone audiometry in frequencies of 250, 500, 1000, 2000, 3000, 4000 and 6000 Hz. Blood samples were collected from each patient for analysis of mutations in nuclear and mitochondrial genes related to non-syndromic sensorineural hearing loss. RESULTS: It was observed a greater tendency to noise exposure and consumption of alcohol in the Case Group. The statistically significant symptoms between the groups were tinnitus and hearing difficulty in several situations as: silent environment, telephone, television, sound location and in church. All the individuals of Case Group presented sensorineural and bilateral hearing loss. The symmetry and progression of the hearing impairment were also statistically significant between the groups. No genetic mutations were identified. CONCLUSION: The most reported symptoms were communication difficulties and tinnitus. The predominant auditory characteristics included sensorineural, bilateral, progressive and symmetrical hearing loss. It was not evidenced a relationship between sensorineural hearing loss in elderly and genes considered responsible for non-syndromic hearing loss as no genetic mutation was found in this study.

Potential Biomarker

Long-term and continuous noise exposure can result in noise-induced hearing loss (NIHL), which is a worldwide problem resulting from the interaction of environmental and genetic factors. The ATP2B2 gene polymorphism can destroy cochlear hair cells and increase the risk of NIHL. A case-control study of 760 Chinese textile workers was conducted to investigate the relationship between ATP2B2 polymorphisms and NIHL susceptibility. Venous blood was collected and questionnaires were conducted by professional physicians. A case group and a control group which were typed by individuals’ pure-tone audiometry test results were set. Three polymorphism sites of ATP2B2 were genotyped by using the PCR technique. Analysis results revealed that the C allele of rs3209637 (95%CI=1.08–2.58, odds ratio OR=1.67, P=0.027) was a dangerous factor and could add to risks of NIHL in the Chinese employees. The data of stratified analysis revealed that individuals who are exposed to noise>95 dB with the rs3209637 C genotype have a higher susceptibility to NIHL (OR=1.34, 95%CI=1.07–1.68). Multifactor dimensionality reduction analysis revealed that the interaction between rs14154 and rs3209637 is linked to increased NIHL risk, and for the interaction among rs14154, smoking and drinking had the same function (OR=1.54 and 1.77, 95%CI=1.15–2.07, 1.33–2.37, and P=0.0037 and P<0.0001, respectively). Our results suggest that genetic polymorphism rs3209637 C within ATP2B2 is a risk factor for NIHL among Chinese employees and rs3209637 C could be a potential biomarker for NIHL patients.

Introduction The tone-evoked auditory brainstem responses (tone-ABR) enable the differential diagnosis in the evaluation of children until 12 months of age, including those with external and/or middle ear malformations. The use of auditory stimuli with frequency specificity by air and bone conduction allows characterization of hearing profile. Objective The objective of our study was to compare the results obtained in tone-ABR by air and bone conduction in children until 12 months, with agenesis of the external auditory canal. Method The study was cross-sectional, observational, individual, and contemporary. We conducted the research with tone-ABR by air and bone conduction in the frequencies of 500 Hz and 2000 Hz in 32 children, 23 boys, from one to 12 months old, with agenesis of the external auditory canal. Results The tone-ABR thresholds were significantly elevated for air conduction in the frequencies of 500 Hz and 2000 Hz, while the thresholds of bone conduction had normal values in both ears. We found no statistically significant difference between genders and ears for most of the comparisons. Conclusion The thresholds obtained by bone conduction did not alter the thresholds in children with conductive hearing loss. However, the conductive hearing loss alter all thresholds by air conduction. The tone-ABR by bone conduction is an important tool for assessing cochlear integrity in children with agenesis of the external auditory canal under 12 months.

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.

Introduction: Oral Submucous Fibrosis (OSMF) is a slowly progressive chronic fibrotic disease of the oral cavity extending to pharynx. Function and patency of eustachian tube gets altered when the palatal and paratubal muscles which regulate the patency of pharyngeal orifice gets affected. This leads to pain in ear along with mild to moderate conductive loss of hearing. Aim: To evaluate hearing deficit in OSMF patients and to correlate clinical stages of OSMF with degree of hearing deficits in patients. Materials and Methods: It was a cross-sectional study. The study comprised of a total of 50 subjects (100 ears). Forty patients diagnosed with OSMF who reported to Department of Oral Medicine and Radiology constituted the study group. Ten normal individuals with no deleterious habits and without any previously diagnosed ear disorders constituted the control group. Pure Tone Audiometry (PTA) was used for evaluating all the subjects for air conduction and bone conduction hearing loss. Values on qualitative characteristics were shown as n (% prevalence) across five study groups. Values on quantitative variables were shown as Mean±SD across five study groups. Inter group comparison for qualitative and quantitative variables was done using chi-square test and analysis of variance (ANOVA) test respectively with Post-Hoc Bonferroni’s correction for multiple group comparisons. Results: The OSMF group showed a marked degree of hearing loss compared to the control group. The distribution of mean PTA in quantitative assessment was significantly higher in group D compared to group A and group B (p-value<0.05 for both) and also the distribution of qualitative hearing loss was significantly higher in group C and group D (p-value<0.05). Conclusion: There was a significant association between OSMF and hearing deficit in this study. Fibrosis of the oropharynx and palatal/paratubal muscles which are affected in OSMF and theses muscles are attached to eustachian tube, the patency of the eustachian tube gets affected. As a result, patients with mainly advanced cases of OSMF should be assessed for hearing deficit.

Objective: To assess the hearing loss among the subjects using excessive mobile phone. Methodology: 50 subjects were entered for this study with age ranging from 20 to 40 years using mobile phone for more than 5 years. 25 subjects who used mobile phone for less than (<) 60 min /day formed one group, while 25 subjects who used cell phone for more than (>) 60 min /day formed the second group. The hearing levels of all the subjects were tested using Pure Tone Audiometry (PTA). Duration of mobile phone usage was assessed by questionnaires. Results: There was a significant increase (p-value .00006) in the hearing thresholds at all frequencies in air conduction and bone conduction in right ear in test group compared with the control group. Similar result was found in the left ear except for bone conduction at frequency 4 and 6 (kilo hertz) kHz. Excessive use of mobile phone caused Sensory neural hearing loss and the prevalence was 84% in group who used mobile phone for > 60 min / day and 20% in group who used for < 60 min / day. Conclusion: Excessive use of mobile phone may cause increase in pure tone threshold associated with the duration of usage. The use for more than 5 years with more than 60 minutes daily can produce harmful effects on human hearing.

A 10-year longitudinal follow-up study of hearing was conducted in patients with nasopharyngeal carcinoma (NPC) in order to elucidate the mechanism of hearing loss in irradiated ears. Ten NPC patients were subjected to a battery of audiological tests before irradiation and 6 months, 5 years, and 10 years after irradiation. The tests included pure tone audiometry, tympanometry, eustachian tube function testing, and myringotomy to confirm middle ear effusion. The prevalences of otitis media with effusion (OME) were 25%, 25%, 40%, and 25% at the 4 testing periods described above, respectively. The prevalences of chronic otitis media were 0%, 0%, 15%, and 25%, respectively. In myringotomized ears (n = 17), the mean hearing levels for both air conduction and bone conduction were preserved from the preirradiation period to 10 years after irradiation. In contrast, in grommeted ears (n = 3), the mean hearing levels for both air conduction and bone conduction deteriorated progressively from the preirradiation period to 10 years after irradiation. We conclude that hearing can be preserved in NPC patients 10 years after irradiation if middle ear inflammation is well controlled. We do not recommend grommet insertion in irradiated NPC patients with OME, as it may result in persistent otorrhea and hearing deterioration.
