The integration of artificial intelligence (AI) into medical disciplines is rapidly transforming healthcare delivery, with audiology being no exception. By synthesizing the existing literature, this review seeks to inform clinicians, researchers, and policymakers about the potential and challenges of integrating AI into audiological practice. The PubMed, Cochrane, and Google Scholar databases were searched for articles published in English from 1990 to 2024 with the following query: "(audiology) AND ("artificial intelligence" OR "machine learning" OR "deep learning")". The PRISMA extension for scoping reviews (PRISMA-ScR) was followed. The database research yielded 1359 results, and the selection process led to the inclusion of 104 manuscripts. The integration of AI in audiology has evolved significantly over the succeeding decades, with 87.5% of manuscripts published in the last 4 years. Most types of AI were consistently used for specific purposes, such as logistic regression and other statistical machine learning tools (e.g., support vector machine, multilayer perceptron, random forest, deep belief network, decision tree, k-nearest neighbor, or LASSO) for automated audiometry and clinical predictions; convolutional neural networks for radiological image analysis; and large language models for automatic generation of diagnostic reports. Despite the advances in AI technologies, different ethical and professional challenges are still present, underscoring the need for larger, more diverse data collection and bioethics studies in the field of audiology.

The auditory brainstem response (ABR) is a noninvasive test that measures neural activity in response to auditory stimuli. Racial differences in head shape have provided strong evidence for specific normative data and accurate device calibration. International standards emphasize the need for standardized procedures and references. This study aimed to outline the standard procedure and related normative ABR values. Standard procedures were performed according to International Electrotechnical Commission (IEC) standards. Five studies from two countries were included to compare the normative values of the ABR. The dataset from the National Standard Reference Data Center (NSRDC) was used as reference. Normative values were described in terms of stimuli, latency, and amplitude. For click stimuli, the latency of the ABR showed different patterns across populations, such as those from Korea and the USA. Although the latencies reported by the NSRDC and for Koreans were relatively short, those reported for USA populations were longer. Using clicks, it was shown that the USA population had the largest ABR amplitude compared to those reported for the other two datasets. For Wave V latency using tone bursts, a similar pattern was identified with click stimuli. Frequency-specific trends were also observed. Although there is a lack of ABR datasets, the information and insights of the present study could be utilized as standard guidelines in research on ABR. [ABSTRACT FROM AUTHOR]

OBJECTIVE: This study aims to identify clinical predictors of treatment response to Eustachian Tube Balloon Dilation (ETBD) as measured by changes in Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) scores. METHODS: One hundred thirteen patients who underwent ETBD at an institution from 2017 to 2021 completed ETDQ-7 pre- and post-operatively. We conducted multivariable regression analyses with ETDQ-7 normalization (0.5 pre-op - post-op), and quantitative improvement in ETDQ-7 score as outcome variables. Pre-operative ETDQ-7 score, tympanogram type, chronic otitis media, chronic rhinosinusitis (CRS), inferior turbinate hypertrophy, deviated septum, allergic rhinitis, and rhinorrhea were included as covariates. Models controlled for age, sex, ethnicity, prior ear or sinus surgery, and follow-up duration. RESULTS: The mean age was 49 years old. 51% were females, and all patients had pre-operative ETDQ-7 above 2.1. After a mean follow-up period of 13 months, 77% achieved MCID and 37% had normalized. Higher pre-operative ETDQ-7 score was associated with greater ETDQ-7 score improvement (B = 0.60, 95% CI = [0.37, 0.83]) and greater odds of achieving MCID (aOR = 1.65; 95% CI = [1.06, 2.59]). A history of CRS improved chances of achieving MCID (aOR = 4.53; 95% CI = [1.11, 18.55]) and a history of chronic otitis media predicted increased odds of ETDQ-7 normalization (aOR = 2.88; 95% CI = [1.09, 7.58]). CONCLUSIONS: Our findings suggest that ETBD was highly effective among patients with pre-operative ETDQ-7 above 2.1. Furthermore, higher pre-operative ETDQ-7 score, CRS, and chronic otitis media predicted more favorable symptomatic benefit from ETBD. These factors may be important to consider when counseling potential candidates for this procedure.

Pure tone audiometry (PTA) is considered the standard method of hearing assessment. However, technical and logistical challenges preclude its usage for hearing screening at primary healthcare facilities. Free field hearing (FFH) tests such as conversation voice (CV) and whispered voice (WV) tests have been used for hearing assessment. However, their correlation to PTA and accuracy in detection of hearing loss are doubtful. This study aims to determine if FFH tests can be used for estimation of hearing thresholds. A retrospective analytical study was conducted at the otorhinolaryngology department. Spearman's correlation coefficient (ρ) was determined between FFH recognition distance and average air conduction PTA thresholds. A statistical regression model was developed to estimate hearing thresholds from the FFH recognition distance. The FFH tests were studied for their accuracy in detection of hearing loss. The audiometric records of 437 persons (874 ears) were analysed. The CV and WV tests were found to have a high correlation (ρ = −0.757 and −0.758, respectively) with average PTA thresholds in persons with hearing loss. The WV test was found to have a 94.7% sensitivity, 90.8% specificity, 97.6% positive predictive value, 80.9% negative predictive value, and 93.9% accuracy in detection of hearing loss. FFH tests such as WV test can be used to estimate the hearing thresholds and screen for hearing loss when audiometric tests are not logistically feasible, such as at primary-level healthcare facilities, remote locations, and in schools. However, such tests should not be regarded as a substitute to PTA. [ABSTRACT FROM AUTHOR]

Background: This study examined the relationship between behavioural thresholds as measured by pure tone audiometry and electrophysiological thresholds measured by the Auditory Steady-State Response (ASSR) in children with normal hearing and sensorineural hearing loss. Materials and Methods: After being assessed, 45 children of both sexes, ranging in age from 5 to 15, were split into four groups: 10 with moderate to moderately severe sensorineural hearing loss (G2M); 10 with steeply sloping sensorineural hearing loss (G2D); 10 with profound and severe sensorineural hearing loss (G2S); and 15 with normal hearing (G1). ASSR, tympanometry, acoustic reflex testing, pure tone audiometry, and speech audiometry (SRT and SDT) were performed. Results: The electrophysiological maximum in the group with normal hearing thresholds varied from 19 to 27 dB NA. The correlation in the group with moderate to moderately severe hearing loss was 0.42–0.74. The correlation in the steeply sloping hearing loss group was 0.68–0.94. The correlation in the group of people with profound and severe hearing loss was 0.59–0.86. The normal hearing group's mean differences in ASSR threshold and audiometric threshold ranged from −0.3 to 12 dB, in the moderate and moderately severe hearing loss group from −9 to 2 dB, in the steeply sloping hearing loss group from 1.4 to 7.5 dB, and in the severe and profound hearing loss group from −0.40 to 8.5 dB. Conclusion: As expected, there was no strong relationship between behavioural and electrophysiological thresholds in the group with normal hearing. But in children with hearing loss, there was a strong correlation between electrophysiological and behavioural thresholds; this relationship was especially evident in children with severe and profound hearing loss and those with steeply sloping hearing loss.

Introduction: To develop and validate a click-based mobile "Audiclick" app employing click noises for hearing assessments. Materials and Methods: This prospective comparative study compares the "AudiClick" app as a hearing screening tool to pure tone audiometry. Participants listened to sounds through wired earbud headphones that were connected to an Android or iOS device. Results: The study involved 110 participants aged between 18 to 80 years old. All degrees of hearing loss severity corresponds to pure tone average (p < 0.01) results. The app was also found to be effective at identifying hearing loss (80-99% sensitivity, specificity, positive predictive value, and accuracy). Testretest reliability had also shown excellent ICC scores of 0.93. Conclusions: This study demonstrates that a mobile app using click sounds can be as efficient as pure tone audiometry for field screenings, while being more cost-effective and easier to develop.

Objective: This study aimed to compare the peripheral-to-central auditory systems of people with coronavirus disease 2019 to a well-matched control group and examine the long-term effects of coronavirus disease 2019 on the auditory system. Method: Participants who were outpatients of coronavirus disease 2019 (n = 30) were compared with a well-matched control group (n = 30). Behavioural and electrophysiological tests were performed, and tests were repeated at six months in the coronavirus disease 2019 group. Results: Statistically significant differences were observed in the right ear at 10 kHz (p = 0.007) and 12.5 kHz (p = 0.028), and in the left ear at 10 kHz (p = 0.040) and 12.5 kHz (p = 0.040) between groups. The groups had no difference regarding the other audiological test results (p > 0.05). Conclusion: Extended high-frequency thresholds were affected in the coronavirus disease 2019 patients. No other findings indicated that the peripheral-to-central auditory system was affected. The effect on extended high-frequency thresholds appeared permanent, but no clinically significant new, late-onset auditory system effects were observed. [ABSTRACT FROM AUTHOR]

Objective: Pure tone audiometry (PTA) is the gold standard for hearing assessment. However, it requires access to specialized equipment. Smartphone audiometry applications (apps) have been developed to perform automated threshold audiometry and could allow patients to perform self‐administered screening or monitoring. This study aimed to assess the validity and feasibility of patients using apps to self‐assess hearing thresholds at home, with comparison to PTA. Methods: A multi‐center, prospective randomized study was conducted amongst patients undergoing PTA in clinics. Participants were randomly allocated to one of four publicly‐available apps designed to measure pure tone thresholds. Participants used an app once in optimal sound‐treated conditions and a further three times at home. Ear‐specific frequency‐specific thresholds and pure tone average were compared using Pearson correlation coefficient. The percentage of app hearing tests with results within ±10 dB of PTA was calculated. Patient acceptability was assessed via an online survey. Results: One hundred thirty‐nine participants submitted data. The results of two at‐home automated smartphone apps correlated strongly/very strongly with PTA average and their frequency‐specific median was within ±10 dB accuracy. Smartphone audiometry performed in sound‐treated and home conditions were very strongly correlated. The apps were rated as easy/very easy to use by 90% of participants and 90% would be happy/very happy to use an app to monitor their hearing. Conclusion: Judicious use of self‐performed smartphone audiometry was both valid and feasible for two of four apps. It could provide frequency‐specific threshold estimates at home, potentially allowing assessments of patients remotely or monitoring of fluctuating hearing loss.

The difficulty in discriminating speech immersed in background noise is a condition that, besides causing discomfort and functional loss in daily activities, is an early indicator of hearing impairment. The evaluation of this hearing function has gained relevance in the field of audiology in recent years, however, there are currently few standardized protocols for its use as a routine audiological screening in Argentina. The purpose of this work is to study the equivalence of the different lists of the BEPPA battery with the aim of adopting it as an assessment tool in the audiology routine. This research was carried out at CINTRA - UE CONICET UTN. A cross-sectional descriptive correlational study of speech discrimination was conducted on 32 young people with normal hearing thresholds UNC and UTN students during the years 2019 and 2020. Normal tonal thresholds (= 21 dB) within the conventional range (250-8000) Hz, hearing rest for at least 8 hours and signed informed consent were established as inclusion criteria. The research was approved by the Institutional Committee for Ethics in Health Research of the Hospital Nacional de Clínicas. Lists of monosyllabic and bisyllabic words, words with consecutive vowel sequences or "vocalic transitions", and sentences with a single intonational group from the BEPPA battery were used. These stimuli were recorded in a CINTRA soundproof chamber, by a professional female speaker and masked using noise with a speech-like spectrum. The signals were reproduced by a digital audiometer. were presented to participants in a binaural dichotic manner in quiet and masked with noise of similar spectral characteristics to those of speech at a signal-to-noise ratio (SNR) of 5dB, 0dB and -5dB, asking them to repeat after each stimulus what they heard aloud. To consider the frequency of use factor on lexical activation, the frequency of each word was recorded using two linguistic corpora of contemporary Spanish as a reference. The results showed statistically significant differences in the number of errors when contrasting the RSR conditions 5dB and 0dB; and between 0dB and -5dB conditions, indicating that they are different enough as evaluation contexts. The contrast of lexical frequencies between the word lists of each category did not show significant differences, so its effect as a confounding factor in the responses obtained could be ruled out. From the observed differences in errors between lists for each category, we can conclude that except for two monosyllabic word lists, the others exhibit equivalent recognition difficulties and are therefore useful for audiological assessment.

Brainstem evoked response audiometry (BERA) is the most established and recommended objective audiometric method for the clinical diagnosis of hearing impairment in high-risk infants. It is unclear whether infants with orofacial clefts meet the criteria for the high-risk group. This retrospective cohort study evaluated the need for diagnostic BERA in infants with cleft palate with or without cleft lip by assessing the predisposition to and diagnosis of congenital hearing impairment. Data from 122 patients treated at a single cleft centre were evaluated. BERA was conducted at the time of palate repair at 4–6 months of age. Clinical follow-up was analysed up to 4 years. The presence of a syndrome was examined as a risk factor for congenital hearing impairment. Among the 122 patients, four had congenital sensorineural or mixed hearing loss requiring hearing aids. All affected patients had syndromes in addition to the cleft. Most patients with elevated hearing thresholds had transient conductive hearing loss. Most suspected sensorineural hearing loss initially diagnosed was refuted. However, a higher incidence of sensorineural hearing loss was found in patients with syndromic clefts, supporting the diagnostic use of BERA with initial surgery only in patients with syndromic clefts.

Introduction NB CE-Chirp LS was developed to improve the audiogram estimation by auditory brainstem response (ABR) thresholds during audiological assessment of infants and difficult to test children. However, before we know how the stimulus behaves in several types of hearing loss, it is important we know how the stimulus behaves in normal hearing infants. Objective To describe ABR thresholds with NB CE-Chirp LS stimulus for 500, 1,000, 2,000, and 4,000 Hz, as well as the amplitude and absolute latency for ABR thresholds. Methods Auditory brainstem response thresholds were evaluated with the Eclipse EP25 system. NB CE-Chirp LS was presented using an ER-3A insert earphone. EEG filter was 30 Hz high-pass and 1,500 Hz low-pass. The ABR threshold was defined as the lowest intensity capable of clearly evoke wave V, accompanied by an absent response 5 dB below. Results Eighteen normal hearing infants were evaluated. The mean and standard deviation (SD) of the ABR threshold (dB nHL) were: 23.8 (±4.2); 14.4 (±5.7); 6.0 (±5.0); and 7.0 (±5.9). The mean and SD of the absolute latency (ms) were: 8.86 (±1.12); 9.21 (±0.95); 9.44 (±0.78); and 9.64 (±0.52). The mean amplitude (nV) and SD were: 0.123 (±0.035); 0.127 (±0.039); 0.141 (±0.052); and 0.105 (±0.028), respectively, for 500, 1,000, 2,000 and 4,000 Hz. Conclusion Auditory brainstem response threshold with NB CE-Chirp LS reaches low levels, in special for high frequencies. It provides absolute latencies similar between frequencies with robust amplitude. The results obtained brings to the examiner more confidence in the results registered. [ABSTRACT FROM AUTHOR]

While noninvasive brain stimulation is convenient and cost effective, its utility is limited by the substantial distance between scalp electrodes and their intended neural targets in the head. The tympanic membrane, or eardrum, is a thin flap of skin deep in an orifice of the head that may serve as a port for improved efficiency of noninvasive stimulation. Here we chose the cochlea as a target because it resides in the densest bone of the skull and is adjacent to many deep-brain-stimulation structures. We also tested the hypothesis that noninvasive electric stimulation of the cochlea may restore neural activities that are missing in acoustic stimulation. We placed an electrode in the ear canal or on the tympanic membrane in 25 human adults (10 females) and compared their stimulation efficiency by characterizing the electrically-evoked auditory sensation. Relative to ear canal stimulation, tympanic membrane stimulation was four times more likely to produce an auditory percept, required eight times lower electric current to reach the threshold and produced two-to-four times more linear suprathreshold responses. We further measured tinnitus suppression in 14 of the 25 subjects who had chronic tinnitus. Compared with ear canal stimulation, tympanic membrane stimulation doubled both the probability (22% vs. 55%) and the amount (-15% vs. -34%) of tinnitus suppression. These findings extended previous work comparing evoked perception and tinnitus suppression between electrodes placed in the ear canal and on the scalp. Together, the previous and present results suggest that the efficiency of conventional scalp-based noninvasive electric stimulation can be improved by at least one order of magnitude via tympanic membrane stimulation. This increased efficiency is most likely due to the shortened distance between the electrode placed on the tympanic membrane and the targeted cochlea. The present findings have implications for the management of tinnitus by offering a potential alternative to interventions using invasive electrical stimulation such as cochlear implantation, or other non-invasive transcranial electrical stimulation methods.

Hearing thresholds provide essential information and references about the human auditory system. This study aimed to identify changing trends in distributions of hearing threshold levels across ages by comparing the International Organization for Standardization (ISO) 7029 and newly available data after publishing ISO 7029. To compare ISO 7029 and newly available hearing threshold data after publishing ISO 7029, four country-specific datasets that presented average hearing threshold levels under conditions similar to ISO 7029 were utilized. For frequencies between 125 Hz and 8,000 Hz, the deviations of hearing threshold values by ages from the hearing threshold of the youngest age group for each data point were utilized. For frequencies from 9,000 Hz to 12,500 Hz, the median threshold information was utilized. Hearing threshold data reported after publishing ISO 7029 from the four countries were mostly similar to the ISO 7029 data but tended to deviate in some age groups and sexes. As national hearing threshold trends change, the following ISO 7029 revision suggests the need to integrate hearing threshold data from different countries. [ABSTRACT FROM AUTHOR]

Introduction Peripheral hearing loss, besides causing inadequate auditory input, can lead to distortions in the tonotopic auditory map and reorganization of neural networks. Therefore, the processing of temporal aspects of a sound stimulus and, consequently, the effectiveness of human communication can be negatively impacted. Objective To test the temporal ordering and auditory resolution of people with mild and moderate sensorineural hearing loss and to compare them with the those of people with normal hearing. Methods A total of 19 right-handed individuals aged 16 to 59 years with mild to moderate postlingually acquired symmetric bilateral sensorineural hearing loss participated in the study. They were submitted to frequency and duration pattern tests and a random gap detection test. Results The mean correct response rate in the frequency pattern test was of 66.3%, and, in the duration pattern test, 71.7%. The mean threshold in the random gap detection test was of 14.1 ms. A comparison with the criteria established for normal subjects without peripheral hearing loss revealed that more than half the subjects had abnormal results in the temporal ordering test, while a smaller fraction had reduced temporal resolution. Conclusions The performance of the subjects with acquired sensorineural hearing loss was poorer than that of the participants without peripheral hearing loss. Their results on the temporal ordering test were also poorer than in the temporal resolution test, demonstrating the importance of analyzing both these auditory skills in people with peripheral hearing loss.

Background: Patients with a cochlear implant (CI) should be evaluated for a new speech processor every 6 years. The aim of this analysis was to assess the subjective and audiological benefit of upgrades. Methods: Speech understanding and subjective benefit were analyzed in 99 patients with the old and the new speech processor after 4 weeks of wearing. Speech understanding was assessed using the Freiburg monosyllabic test in quiet (FBE) at 65 dB and 80 dB, and the Oldenburg Sentence Test (OLSA) at 65 dB noise with adaptive speech sound level. The Abbreviated Profile of Hearing Aid Benefit (APHAB) was used to assess subjective hearing impairment, and the Audio Processor Satisfaction Questionnaire (APSQ) was used to assess subjective satisfaction. Results: The speech processor upgrade resulted in a significant improvement of speech understanding in quiet at 65 dB (mean difference 8.9 ± 25.9 percentage points, p < 0.001) and 80 dB (mean difference 8.1 ± 29.7 percentage points, p < 0.001) and in noise (mean difference 3.2 ± 10.7 dB signal-to-noise ratio [S/N], p = 0.006). Using the APHAB, a significant improvement (mean difference 0.07 ± 0.16, p < 0.001) in hearing impairment was demonstrated in all listening situations. The APSQ showed significantly higher patient satisfaction with the new speech processor (mean difference 0.42 ± 1.26, p = 0.006). A comparative assessment of the benefit based on subjective and speech audiometric results identified a proportion of patients (35–42%) who subjectively benefited from the upgrade but had no measurable benefit based on speech audiometry. Conclusion: There was a significant improvement in audiologically measurable and subjectively reflected speech understanding and patient satisfaction after the upgrade. In patients with only a small improvement in audiologically measurable speech understanding, the subjective benefit should also be assessed with validated measurement instruments in order to justify an upgrade to the payers in the health sector.

BackgroundThe aim of this study is to evaluate the current state of ototoxicity monitoring for patients receiving cisplatin chemotherapy in an academic medical center with particular attention to how closely monitoring adheres to national ototoxicity guidelines.MethodsCase series including retrospective medical records review of patients (age > 18) treated with cisplatin at University of California Davis Medical Center between January 2014 and August 2017. Patient and ototoxicity related variables were analyzed. Patients that underwent a transfer of care during treatment and with less than 3 months of follow-up were excluded.ResultsThree hundred seventy-nine patients met study criteria, of which 104 (27.4%) had a prior history of hearing loss. Prior to treatment, 196 (51.7%) patients were counseled regarding the ototoxic nature of cisplatin and 92 (24.3%) patients had a pretreatment audiogram. During treatment, 91 (24%) patients had documented otologic complaints. Only 17 patients (4.5%) patients had an audiogram ordered during their cisplatin treatment period. 130 (34.3%) patients had otologic complaints following cisplatin treatment. Audiograms were ordered for 20 (7.8%), 13 (5.1%), and 16 (6.2%) patients at 1-month, 3-month, and 6-month follow-ups, respectively. No patients in the study cohort received baseline, treatment, and post-treatment audiograms as recommended by national ototoxicity monitoring protocols. Patients with Head and Neck Cancer (HNC) represented the largest subgroup that received cisplatin (n = 122, 32.2%) and demonstrated higher rates of ototoxicity counseling (n = 103, 84.4%) and pretreatment audiograms (n = 70, 57.4%) compared to the non HNC group (n = 36, 36.2%, P

ImportanceAge-related sensorineural hearing loss is a common health problem among adults. Nearly 16% of US adults 18 years or older report difficulty hearing. The prevalence of perceived hearing loss increases with age. Hearing loss can adversely affect an individual's quality of life and ability to function independently and has been associated with increased risk of falls, hospitalizations, social isolation, and cognitive decline.ObjectiveTo update its 2012 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a systematic review on screening for hearing loss in adults 50 years or older.PopulationAsymptomatic adults 50 years or older with age-related hearing loss.Evidence assessmentBecause of a lack of evidence, the USPSTF concludes that the benefits and harms of screening for hearing loss in asymptomatic older adults are uncertain and that the balance of benefits and harms cannot be determined. More research is needed.RecommendationThe USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for hearing loss in older adults.

Background:Hearing loss is one of the most prevalent chronic health conditions. Traditional pure tone audiometry (PTA) is the gold standard for hearing loss screening, but is not widely available outside specialized clinical centers. Mobile health (mHealth)-based audiometry could improve access and cost-effectiveness, but its diagnostic accuracy varies widely between studies. Therefore, we aimed to evaluate the diagnostic accuracy of mHealth-based audiometry for hearing loss screening in adults compared with traditional PTA. Methods:Ten English and Chinese databases were searched from inception until April 30, 2022. Two researchers independently selected studies, extracted data, and appraised methodological quality. The bivariate random-effects model was adopted to estimate the pooled sensitivity and specificity for each common threshold (i.e., the threshold to define mild or moderate hearing loss). The hierarchical summary receiver operating characteristic model was used to assess the area under the receiver operating characteristic curve (AUC) across all thresholds. Results:Twenty cohort studies were included. Only one study (n = 109) used the mHealth-based speech recognition test (SRT) as the index test. Nineteen studies (n = 1,656) used mHealth-based PTA as the index test, and all of them were included in the meta-analysis. For detecting mild hearing loss, the pooled sensitivity and specificity were 0.91 (95% confidence interval [CI] 0.80–0.96) and 0.90 (95% CI 0.82–0.94), respectively. For detecting moderate hearing loss, the pooled sensitivity and specificity were 0.94 (95% CI 0.87–0.98) and 0.87 (95% CI 0.79–0.93), respectively. For all PTA thresholds, the AUC was 0.96 (95% CI 0.40–1.00). Conclusions:mHealth-based audiometry provided good diagnostic accuracy for screening both mild and moderate hearing loss in adults. Given its high diagnostic accuracy, accessibility, convenience, and cost-effectiveness, it shows enormous potential for hearing loss screening, particularly in primary care sites, low-income regions, and settings with in-person visit limitations. Further work should evaluate the diagnostic accuracy of the mHealth-based SRT tests. [ABSTRACT FROM AUTHOR]

ObjectiveTo review the otologic outcomes of infants who failed the newborn hearing screen (NBHS) and received early tympanostomy tubes for otitis media with effusion (OME).Study designRetrospective case series.SettingTertiary care pediatric hospital.Subjects and methodsConsecutive patients (2007-2018) who failed an NBHS and required tympanostomy tubes before 6 months of age were included. Variables including hearing loss and otitis media risk factors, episodes of acute otitis media (AOM), number of subsequent tympanostomy tubes, and posttympanostomy tube audiogram results were recorded.ResultsThe cohort included 171 patients. Median age at referral to otolaryngology was 2.7 months. Sensorineural hearing loss (SNHL) was subsequently identified in 22 (12.9%) of infants after resolution of the effusion. The peak incidence of AOM was during the second year of life (1-1.9 years), with a median of 1 episode. Ninety-five patients (55.6%) had replacement of tubes, 41 of 171 (24.0%) had 2 or more additional sets of tubes, and long-term tubes were eventually placed in 8 of 95 (8.4%) patients. Craniofacial anomalies were identified in 43.3% of patients. Tube replacement (hazard ratio, 3.00; 95% CI, 1.95-4.63; P < .01, log-rank) and AOM (β, 1.04; 95% CI, 0.43-1.65; P = .04, ordered logistic regression) were more common, and SNHL less common (odds ratio, 0.17; 95% CI, 0.031-0.61; P < .01, logistic regression), in children with craniofacial anomalies.ConclusionOME is a common cause of failed NBHS. A notable proportion was subsequently found to have SNHL, reiterating the need for postoperative hearing assessments. Infants meeting indication for early tympanostomy tubes for resolution of OME have a high incidence of recurrent AOM and require subsequent tubes.

ObjectiveTo test the hypothesis that incipient Alzheimer disease (AD) may adversely affect hearing and that hearing loss may adversely affect cognition, we evaluated whether genetic variants that increase AD risk also increase problem hearing and genetic variants that increase hearing impairment risk do not influence cognition.MethodsUK Biobank participants without dementia ≥56 years of age with Caucasian genetic ancestry completed a Digit Triplets Test of speech-in-noise hearing (n = 80,074), self-reported problem hearing and hearing with background noise (n = 244,915), and completed brief cognitive assessments. A genetic risk score for AD (AD-GRS) was calculated as a weighted sum of 23 previously identified AD-related polymorphisms. A genetic risk score for hearing (hearing-GRS) was calculated using 3 previously identified polymorphisms related to hearing impairment. Using age-, sex-, and genetic ancestry-adjusted logistic and linear regression models, we evaluated whether the AD-GRS predicted poor hearing and whether the hearing-GRS predicted worse cognition.ResultsPoor speech-in-noise hearing (>-5.5-dB speech reception threshold; prevalence 14%) was associated with lower cognitive scores (ß = -1.28; 95% confidence interval [CI] -1.54 to -1.03). Higher AD-GRS was significantly associated with poor speech-in-noise hearing (odds ratio [OR] 1.06; 95% CI 1.01-1.11) and self-reported problems hearing with background noise (OR 1.03; 95% CI 1.00-1.05). Hearing-GRS was not significantly associated with cognitive scores (ß = -0.05; 95% CI -0.17 to 0.07).ConclusionsGenetic risk for AD also influences speech-in-noise hearing. We failed to find evidence that genetic risk for hearing impairment affects cognition. AD disease processes or a that shared etiology may cause speech-in-noise difficulty before dementia onset.

This study aims to determine the degree to which Portable Automated Rapid Testing (PART), a freely available program running on a tablet computer, is capable of reproducing standard laboratory results. Undergraduate students were assigned to one of three within-subject conditions that examined repeatability of performance on a battery of psychoacoustical tests of temporal fine structure processing, spectro-temporal amplitude modulation, and targets in competition. The repeatability condition examined test/retest with the same system, the headphones condition examined the effects of varying headphones (passive and active noise-attenuating), and the noise condition examined repeatability in the presence of recorded cafeteria noise. In general, performance on the test battery showed high repeatability, even across manipulated conditions, and was similar to that reported in the literature. These data serve as validation that suprathreshold psychoacoustical tests can be made accessible to run on consumer-grade hardware and perform in less controlled settings. This dataset also provides a distribution of thresholds that can be used as a normative baseline against which auditory dysfunction can be identified in future work.

ObjectivesTo evaluate the efficacy of a multi-modal migraine prophylaxis therapy for patients with hyperacusis.MethodsIn a prospective cohort, patients with hyperacusis were treated with a multi-modal step-wise migraine prophylactic regimen (nortriptyline, verapamil, topiramate, or a combination thereof) as well as lifestyle and dietary modifications. Pre- and post-treatment average loudness discomfort level (LDL), hyperacusis discomfort level measured by a visual analogue scale (VAS), and scores on the modified Khalfa questionnaire for severity of hyperacusis were compared.ResultsTwenty-two of the 25 patients (88%) reported subjective resolution of their symptoms following treatment. Post-treatment audiograms showed significant improvement in average LDL from 81.3 ± 3.2 dB to 86.4 ± 2.6 dB (P < .001), indicating increased sound tolerability. The VAS discomfort level also showed significant improvement from a pre-treatment average of 7.7 ± 1.1 to 3.7 ± 1.6 post-treatment (P < .001). There was also significant improvement in the average total score on modified Khalfa questionnaire (32.2 ± 3.6 vs 22.0 ± 5.7, P < .001).ConclusionsThe majority of patients with hyperacusis demonstrated symptomatic improvement from migraine prophylaxis therapy, as indicated by self-reported and audiometric measures. Our findings indicate that, for some patients, hyperacusis may share a pathophysiologic basis with migraine disorder and may be successfully managed with multimodal migraine prophylaxis therapy.

Background There is currently insufficient effective treatment for hearing loss in the elderly since it is a hidden disease whose damage is irreversible. It is crucial to establish early warnings, screenings and interventions. As of now, there are few studies carried out on the assessment of hearing loss in the elderly based on risk factors at home and abroad. There are no standardized measurement tools or perfect scales. Objective Utilizing smart medicine and the WeChat platform, investigate high-risk factors of hearing loss in the elderly, develop screening software for hearing loss in the elderly, and explore the screening and management modes of hearing loss in the elderly. Methods Based on cross-sectional survey, five community health service centers in Pudong New Area of Shanghai were obtained. The tudy was performed from April to December 2019 to investigate the distribution of risk factors for hearing loss in the elderly in the community, and conditional logic was applied, and receiver operation charateristic curve (ROC curve) were used for risk stratification. The screening software for hearing loss in the elderly has been developed using JavaScript language during the period January and June 2020. Verification and evaluation of the screening software were performed between July 2020 to March 2021. Results The study involved 401 elderly peoplein across-sectional design. Multivariate Logistic regression analysis revealed that aging〔OR=1.100, 95%CI (1.037, 1.166) 〕, noise history〔OR=3.886, 95%CI (1.077, 14.022) 〕, non-light diet〔OR=2.445, 95%CI (1.127, 5.305) 〕, hypertension〔OR=1.8393, 95%CI (1.015, 3.330) 〕, diabetes〔OR=4.310, 95%CI (1.817, 10.225) 〕and hyperuricemia〔OR=3.174, 95%CI (1.030, 9.779) 〕were independent risk factors (P

Carbon monoxide (CO) can cause "irreversible" severe-to-profound sensorineural hearing loss. However, there are few reports of detailed hearing test results. Here, we report a case of acute sensorineural hearing loss caused by acute CO poisoning with partial hearing recovery, evaluated by a detailed hearing examination. A 25-year-old woman was brought to the emergency department for attempted suicide. On admission, her consciousness was impaired, and she was treated for severe CO poisoning, including using hyperbaric-oxygen therapy. After regaining consciousness, symptoms of hearing loss and tinnitus were discovered, and a detailed audiological examination revealed bilateral hearing loss, suggesting cochlear damage. Steroids were systemically administered, and her hearing impairment was partially resolved. Sensorineural hearing loss caused by acute CO poisoning includes cochlear pathology and may be partially treatable. The early evaluation of hearing in patients with severe CO poisoning is advisable for early treatment. [ABSTRACT FROM AUTHOR]

Background: If sufficient speech discrimination is no longer achieved with conventional hearing systems, an audiological indication for a cochlear implant (CI) is given. However, there are no established target criteria for CI aftercare with regard to the level of speech comprehension to be achieved. The aim of this study is to validate an existing predictive model for speech comprehension after CI provision. This is applied to different patient groups. Materials and methods: The prospective study included 124 postlingually deaf adults. The model is based on preoperative maximum monosyllabic recognition score, aided monosyllabic recognition score at 65 dBSPL, and age the time of implantation. The model was investigated with regard to prediction accuracy for monosyllabic recognition with CI after 6 months. Results: Mean speech discrimination improved from 10% with hearing aid to 65% with CI after 6 months, with a statistically significant improvement in 93% of cases. Deterioration of aided unilateral speech discrimination was not observed. The mean prediction error was 11.5 percentage points in the cases with preoperative scores better than zero and 23.2 percentage points in all other cases. Conclusion: Cochlear implantation should also be considered in patients with moderately severe to severe hearing loss and insufficient speech discrimination with hearing aids. The model based on preoperatively measured data for predicting speech discrimination with CI can be used in preoperative consultation and in the context of postoperative quality assurance.

ABSTRACT Purpose: to analyze the Brazilian bibliographic production, in the last decade, regarding the most used behavioral tests to assess central auditory processing in children. Methods: an integrative literature review, whose research question was, “Which behavioral tests are most used to assess children’s central auditory processing?”. The following search strategy “(auditory processing) AND (behavioral tests) AND (children)”, was used to consult the Oasisbr, VHL, and SciELO databases. Free-access studies, published in full text in national and international journals, in Brazilian Portuguese or English, with replicable methods, and whose descriptors and topics answered the research question, were selected. Reviews, opinion articles, administration reports, websites, policies with indicators, information systems, and repeated or duplicate publications, were excluded. Two researchers conducted the analysis, and the studies were classified as either feasible or unfeasible. Data were collected between September and November 2021 and organized in tables and spreadsheets developed in Microsoft Excel. Literature Review: initially, 64 studies were located, but after applying the eligibility criteria, 28 publications remained, which were read in full text. Conclusion: the Frequency Pattern Test, Dichotic Digits Test, Gaps in Noise Test, Speech-in-Noise Test, and Pediatric Speech Intelligibility were the most used behavioral tests to assess children’s auditory processing.

Background and Aim: Word Recognition Test (WRT) is a widely used component of routine audiology battery. Several studies were conducted on the effect of words in word recognition lists and whether word difficulty level had an effect in word recalling process of patients. This study aims to compare the scores of patients to the designed Başkent WRT and commonly used Hacettepe WRT by focusing on the lexical neighbourhood. Methods: Study carried out in an Ear Nose and Throat Department of a private university hospital between June and August 2021. 34 persons with sensorineural hearing loss and 34 persons without hearing loss was participated in the study. Designed WRT and widely used common WRT were presented to the participants. Results: Results showed that common WRT included words with more lexical neighbours and sensorineural hearing loss group scores were significantly lower compared to designed WRT. Conclusion: Persons with sensorineural hearing loss have a tendency to misunderstand presented words in WRT as they may trigger other words and misguide the patient. [ABSTRACT FROM AUTHOR]

Background and Objectives: The speech tests used to evaluate language performance in patients with bilateral deafness (BiD) and cochlear implant (CI) are problematic if applied to patients with single-sided deafness (SSD) because normal ear hearing should be excluded. Thus, we investigated the feasibility of using wireless connection to evaluate speech intelligibility of the CI ear in patients with SSD. Subjects and Methods: Patients with BiD and SSD were administered the word recognition scores (WRS) and speech intelligibility tests using an iPad-based wireless connection and conventional methods. To exclude normal side hearing in patients with SSD, masking noise and "plugged and muffed" method were used in the WRS and speech intelligibility tests, respectively. Results: In patients with BiD, the WRS and speech intelligibility tests results using wireless connection and conventional methods were similar. In patients with SSD, the WRS using masking noise in the normal hearing ear was similar to that of using wireless connection. However, 3 of 11 patients with SSD showed under-masked results if using the "plugged and muffed" method. Conclusions: Speech intelligibility testing using wireless connection is a convenient and reliable method for evaluating CI performance in patients with SSD. The "plugged and muffed" method is not recommended for evaluating CI performance in patients with SSD. [ABSTRACT FROM AUTHOR]

HYPOTHESIS: We hypothesize that internal auditory canal (IAC) diverticula occur independent of otosclerosis as demonstrated by temporal bone histopathology. BACKGROUND: Diverticula at the anterior-inferior aspect of the IAC have been described histologically in the setting of cavitary otosclerosis. Recent radiographic studies show the prevalence of IAC diverticula that is higher than what can be accounted for by cavitary otosclerosis alone. METHODS: We examined hematoxylin and eosin temporal bone histopathology slides with otosclerosis involving the IAC. We also examined bones from normal hearing subjects with normal histologic findings. Temporal bones were included if donors were more than 18 years of age at time of death and adequate horizontal cuts were available to evaluate the area of interest. RESULTS: IAC diverticula were found in 33 of 47 (70%) temporal bones with IAC otosclerosis and in 5 of 20 (25%) normal temporal bones. The difference in mean pure tone averages (PTA) in the normal temporal bones with (PTA 7.3 ± 7) and without (PTA 8 ± 2) diverticula was not statistically significant (p = 0.86). CONCLUSION: IAC diverticula which have been previously demonstrated to occur in the setting of cavitary otosclerosis can also occur independent from otosclerosis. Subjects with diverticula but without other temporal bone pathology have normal hearing thresholds.

ABSTRACT Purpose To analyze the performance of students aged between in an auditory skills screening software program, considering the influence of biological determinants and the correlation of auditory tasks with the behavioral assessment tests of central auditory processing (PAC), as well as to present the cutoff points of the battery. Methods In the first stage, the sample consisted of 96 students with typical development, who underwent hearing screening at school. A self-perception questionnaire and the auditory tasks of sound localization (SL), temporal resolution (TR), temporal ordering of frequency (OT-F) and duration (OT-D), auditory closure (AC), dichotic digit- binaural integration (DD) and figure-ground (FG) were applied. Of these, 66 children participated in the second stage of the study, including basic and behavioral audiological assessment from PAC. Results The gender variable influenced the DD task to the right ear. Age influenced the outcome of five auditory tasks. The right ear performed better in the DD and OT-F tasks. At the age between 6 and 7 years, there was a correlation between screening and diagnosis in the tasks of AC, TR, DD, FG, and OT-F. At the age of 8 years, there was a correlation in the DD and OT-F tasks. The pass/fail criteria varied according to the task and biological determinants. Conclusion There was a correlation between screening and diagnosis in a greater number of tasks in the age group between 6 and 7 years. The cut-off points for the auditory tasks should be analyzed according to age, sex and/or ear side.

Recent studies involving guinea pigs have shown that noise can damage the synapses between the inner hair cells and spiral ganglion neurons, even with normal hearing thresholds—which makes it important to investigate this kind of impairment in humans. The aim was to investigate, with multiple audiological assessments, the auditory function of normal hearing workers exposed to occupational noise. Altogether, 60 workers were assessed (30 in the noise-exposure group [NEG], who were exposed to occupational noise, and 30 in the control group [CG], who were not exposed to occupational noise); the workers were matched according to age. The following procedures were used: complete audiological assessment; speech recognition threshold in noise (SRTN); speech in noise (SN) in an acoustic field; gaps-in-noise (GIN); transient evoked otoacoustic emissions (TEOAE) and inhibitory effect of the efferent auditory pathway; auditory brainstem response (ABR); and long-latency auditory evoked potentials (LLAEP). No significant difference was found between the groups in SRTN. In SN, the NEG performed worse than the CG in signal-to-noise ratio (SNR) 0 (p-value 0.023). In GIN, the NEG had a significantly lower percentage of correct answers (p-value 0.042). In TEOAE, the NEG had smaller amplitude values bilaterally (RE p-value 0.048; LE p-value 0.045) and a smaller inhibitory effect of the efferent pathway (p-value 0.009). In ABR, the NEG had greater latencies of wave V (p-value 0.017) and interpeak intervals III-V and I-V in the LE (respective p-values: 0.005 and 0.04). In LLAEP, the NEG had a smaller P3 amplitude bilaterally (RE p-value 0.001; LE p-value 0.002). The NEG performed worse than the CG in most of the assessments, suggesting that the auditory function in individuals exposed to occupational noise is impaired, even with normal audiometric thresholds.

Among the many questions regarding the ability to effortlessly name musical notes without a reference, also known as absolute pitch, the neural processes by which this phenomenon operates are still a matter of debate. Although a perceptual subprocess is currently accepted by the literature, the participation of some aspects of auditory processing still needs to be determined. We conducted two experiments to investigate the relationship between absolute pitch and two aspects of auditory temporal processing, namely temporal resolution and backward masking. In the first experiment, musicians were organized into two groups according to the presence of absolute pitch, as determined by a pitch identification test, and compared regarding their performance in the Gaps-in-Noise test, a gap detection task for assessing temporal resolution. Despite the lack of statistically significant difference between the groups, the Gaps-in-Noise test measures were significant predictors of the measures for pitch naming precision, even after controlling for possible confounding variables. In the second experiment, another two groups of musicians with and without absolute pitch were submitted to the backward masking test, with no difference between the groups and no correlation between backward masking and absolute pitch measures. The results from both experiments suggest that only part of temporal processing is involved in absolute pitch, indicating that not all aspects of auditory perception are related to the perceptual subprocess. Possible explanations for these findings include the notable overlap of brain areas involved in both temporal resolution and absolute pitch, which is not present in the case of backward masking, and the relevance of temporal resolution to analyze the temporal fine structure of sound in pitch perception.

Objective: The aim of this study is to investigate how the three commonly used word lists in our country (Hacettepe, Marmara and Başkent lists) are developed in the speech recognition threshold (SRT) test, which is a part of the routine audiological evaluation, and to examine the variety of words and phoneme content in the lists. Material and Methods: Information about the SRT test word lists used in Hacettepe, Marmara and Başkent Universities was obtained from the developers and the lists were collected in the Excel database, and word diversity (noun, adjective or adverb, exclamation and verb) was determined based on the dictionaries of the Turkish Language Institution, and then the Contemporary Türkiye Turkish of the International Phonetic Association phoneme definitions, vowel and consonant phoneme distributions are revealed. Moreover; the ratios of two vowels (/i, e/) voiced in the front of the mouth and three vowels (/a, o, u/) voiced in the back and the ratios of nasal phonemes (/m, n/) were found separately. Results: It is reported that the existing SRT test lists are prepared from 3-syllable words based on intelligibility and the word variety and structure of Turkish. It was emphasized that the Marmara list was prepared especially from materials for children. While the Hacettepe list is the richest list in terms of the number of words and phonemes, it is also the list where non-noun words are used the most. It is seen that the lists have similar phoneme balance, although they show some differences. However, it is seen that the /ɣ/(ğ) phoneme is used relatively more in the Marmara list, and the rate of vowels in general and especially front vowels is lower than in other lists. Conclusion: The Hacettepe list stands out with its widespread use and the diversity of its word and phoneme content. On the other hand, the Marmara list is specially prepared from materials for children and seems to be a more sensitive list for hearing loss at relatively high frequencies. The list of capitals draws attention in terms of the fact that the words are mostly composed of nouns and the order of the word structures. The lack of psychometric curves of existing word lists is a major shortcoming. [ABSTRACT FROM AUTHOR]

Noninvasive transcranial or minimally invasive transtympanic electric stimulation may offer a desirable treatment option for tinnitus because it can activate the deafferented auditory nerve fibers while posing little to no risk to hearing. Here, we built a flexible research interface to generate and control accurately charge-balanced current stimulation as well as a head-mounted instrument capable of holding a transtympanic electrode steady for hours. We then investigated the short-term effect of a limited set of electric stimulation parameters on tinnitus in 10 adults with chronic tinnitus. The preliminary results showed that 63% of conditions of electric stimulation produced some degree of tinnitus reduction, with total disappearance of tinnitus in six subjects in response to at least one condition. The present study also found significant side effects such as visual, tactile, and even pain sensations during electric stimulation. In addition to masking and residual inhibition, neuroplasticity is likely involved in the observed tinnitus reduction. To translate the present electric stimulation into a safe and effective tinnitus treatment option, we need to optimize stimulation parameters that activate the deafferented auditory nerve fibers and reliably suppress tinnitus, with minimal side effects and tolerable sensations. Noninvasive or minimally invasive electric stimulation can be integrated with sound therapy, invasive cochlear implants, or other forms of coordinated stimulation to provide a systematic strategy for tinnitus treatment or even a cure.

Zika virus (ZIKV) infection can result in hearing loss in babies, consequently, audiological monitoring is necessary. This study aimed to evaluate the frequency of hearing impairment in neonates and children exposed to ZIKV during the intrauterine period. A cohort of 30 children born to mothers infected with ZIKV during pregnancy (March 2016–January 2017) underwent repeated hearing assessments performed 48 h after birth. Universal Newborn Hearing Screening revealed normal results in all children at 6, 13, 24, and 36 months. Children were divided into two subgroups based on real-time polymerase chain reaction: RT-PCR(+) and RT-PCR(-). At 24 months, the cumulative incidence of hearing alteration was 57.1%. There was no significant difference in the detection of hearing alteration between RT-PCR(+) and (-) groups. None of the children had sensorineural hearing loss; None of the children had sensorineural hearing loss. Total incidence conductive type (per 1000 live births), RT-PCR ZIKV (-) 2.2, prevalence 20% and RT-PCR ZIKV 3.1, prevalence 35.7%.The incidence of hearing alteration was highest at 24 months of age (57.1%, n = 8; only conductive type).

Objective: To investigate the detection of the age and pathway and the etiology of sensorineural hearing loss in children, and to guide the early diagnosis. Methods: A retrospective analysis was conducted on the children who passed neonatal hearing screening but were diagnosed with sensorineural hearing loss in our department from January 2019 to September 2022. The clinical characteristics of 66 children with complete medical history, audiology examination, imaging examination and genetic detection of hearing loss were studied. The age group, detection route and degree of hearing loss were analyzed statistically. Results: ①The children were aged from 7 months to 12 years old, and most of them were over 3 years old. ②The ways of detection were as follows: 23 cases（34.85%） due to abnormal hearing, 21 cases（31.82%） due to poor language, 15 cases（22.73%） found during physical examination, and 7 cases（10.61%） found with otitis media. Physical examination findings were concentrated in children aged ≤1 year old or 3-6 years old. ③Among the 56 cases, the degree of binaural hearing loss ranged from mild to severe, and most of those within 3 years of age had severe or above hearing loss. There were statistically significant differences in the degree of hearing loss distribution among different detection approaches（ P <0.001）. Most children with hearing or language problems had moderate to severe or above hearing loss, and the proportion was significantly higher than that of children detected during physical examination or otitis media. ④There were 21 cases（31.82%） with a pathogenic mutation of GJB2 gene and 9 cases（13.64%） of large vestibular aqueduct syndrome, 7 of which were related to SLC26A4 gene mutation. There were 8 cases（12.12%） with high risk factors of hearing loss. There was 1 case（1.52%） with progressive speech loss after severe infection and high fever and 1 case（1.52%） with unilateral cochlear nerve dysplasia. Conclusion: Delayed hearing loss can occur at all ages and was not easy to be detected in time. The etiology was related to the mutation of deafness-related genes and the high risk factors of hearing loss. Combining hearing and gene screening in childhood, guiding parents to observe children's hearing response and language development, especially strengthening the follow-up of children with high risk factors for hearing loss, is conducive to the early diagnosis of delayed hearing loss., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.)

Objectives: This study compares auditory processing performance across different decades of adulthood, including young adults and middle-aged individuals with normal hearing and no spontaneous auditory complaints., Design: We assessed 80 participants with normal hearing, at least 10 years of education, and normal global cognition. The participants completed various auditory tests, including speech-in-noise, dichotic digits, duration, pitch pattern sequence, gap in noise, and masking level difference. In addition, we conducted working memory assessments and administered a questionnaire on self-perceived hearing difficulties., Results: Our findings revealed significant differences in auditory test performance across different age groups, except for the masking level difference. The youngest group outperformed all other age groups in the speech-in-noise test, while differences in dichotic listening and temporal resolution emerged from the age of 40 and in temporal ordering from the age of 50. Moreover, higher education levels and better working memory test scores were associated with better auditory performance as individuals aged. However, the influence of these factors varied across different auditory tests. It is interesting that we observed increased self-reported hearing difficulties with age, even in participants without spontaneous auditory complaints., Conclusions: Our study highlights significant variations in auditory test performance, with noticeable changes occurring from age 30 and becoming more pronounced from age 40 onward. As individuals grow older, they tend to perceive more hearing difficulties. Furthermore, the impact of age on auditory processing performance is influenced by factors such as education and working memory., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objective: To analyze the hearing outcomes of high-risk children of diabetic mothers, especially in the subtypes of pre-pregnancy diabetes and gestational diabetes, in order to provide some reference for clinical practice. Methods: The basic characteristics and hearing levels of children whose mothers had a history of diabetes during pregnancy and underwent audiological diagnosis and evaluation at our hospital's Children's Hearing Diagnosis Center from January 2003 to June 2024 were analyzed. T-tests, Wilcoxon rank-sum tests, and chi-square tests were used for inter-group comparisons, with a significance level set at P <0.05. Results: A total of 285 children（570 ears） of diabetic mothers were included. Hearing loss was found in 310 ears, and the incidence of hearing loss was 54.39%（310/570）. The mean ABR threshold in the pregestational diabetes group was（50.01±29.29） dB HL, while that in the gestational diabetes group was（44.13±26.19） dB HL. The degree of hearing loss in the pregestational diabetes group was more severe than that in the gestational diabetes group（χ²=10.000, P =0.019）. Conclusion: Maternal history of diabetes may be one of the risk factors for hearing loss in their offspring, and the risk of hearing loss in children whose mothers had diabetes before pregnancy may be higher than that in the gestational diabetes group. It is suggested that the clinical practice should pay attention to the monitoring and follow-up management of the hearing status of such children, so as to improve the auditory outcomes of children born to diabetic mothers., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.)
