RESUMO
Background and Objectives: Besides classical stapedotomy, reverse stapedotomy has been used for many years in the management of otosclerosis. Our study aims to investigate whether reversing the surgical steps in stapedotomy impacts vestibular function and hearing improvement. Materials and Methods: A cohort of 123 patients underwent either classic or reverse stapedotomy procedures utilizing a fiber-optic argon laser. Audiological assessments, following the guidelines of the Committee on Hearing and Equilibrium, were conducted, including pure tone average, air-bone (AB) gap, overclosure, and AB gap closure. Vestibular evaluation involved pre- and postoperative comparison of rotatory test parameters, including frequency, amplitude, and slow phase velocity of nystagmus. Results: The study demonstrated an overall median overclosure of 3.3 (3.3, 5.0) dB and a mean AB gap closure of 20.3 ± 8.8 dB. Postoperative median AB gap was 7.5 (7.5, 11.3) dB in the reverse stapedotomy group and 10.0 (10.0, 12.5) dB in the classic stapedotomy group. While overclosure and AB gap closure were marginally superior in the reverse stapedotomy group, these differences did not reach statistical significance. No significant disparities were observed in the frequency, slow phase velocity, or amplitude of nystagmus in the rotational test. Conclusions: Although not always possible, reverse stapedotomy proved to be a safe surgical technique regarding postoperative outcomes. Its adoption may mitigate risks associated with floating footplate, sensorineural hearing loss, and incus luxation/subluxation, while facilitating the learning curve for less experienced ear surgeons.

Objective: This study aimed to compare the audiological characteristics between children with unilateral auditory neuropathy (UAN) and single-sided deafness (SSD) to establish a valid basis for the differential diagnosis of children with UAN. Methods: A retrospective analysis was conducted on audiological and imaging evaluations of children with UAN and SSD who were treated at Beijing Children's Hospital of Capital Medical University between May 2015 and June 2023. There were 17 children with UAN, comprising 10 males and 7 females, with an average age of 4.7 years. Additionally, there were 43 children with SSD, consisting of 27 males and 16 females, with an average age of 6.5 years. Audiological assessments included Auditory brainstem response (ABR), Steady-state auditory evoked potential (ASSR), Behavioural audiometry, Cochlear microphonic potential (CM), Distortino-product otoacoustic emission (DPOAE), and acoustic immittance test. The results of the audiological assessment and imaging phenotypic between the two groups of children were compared and analyzed by applying SPSS 27.0 statistical software. Results: (1) The UAN group (77.8%) had a significantly higher rate of ABR wave IIIL than the SSD group (20.9%) (P<0.01). The PA thresholds at 500 Hz and 1 000 Hz of children with SSD were higher than those of children with UAN, while the ASSR thresholds at 500 Hz, 1000 Hz, 2 000 Hz, and 4 000 Hz of children with SSD were significantly higher than those of children with UAN (P<0.05). (2) The degree of hearing loss in both UAN and SSD children was predominantly complete hearing loss. The percentage of complete hearing loss was significantly higher (χ²=4.353, P=0.037) in the SSD group (93.0%, 40/43) than in the UAN group (63.6%, 7/11). However, the percentage of profound hearing loss was significantly higher in the UAN group (27.3%, 3/11) than in the SSD group (2.3%, 1/43) (Fisher's exact test, P=0.023). In terms of hearing curve configuration, the percentage of flat type was significantly higher in the SSD group (76.7%, 33/43) than in the UAN group (36.4%, 4/11). The proportion of the UAN group (27.3%, 3/11) was significantly higher than that in the SSD group (2.3%, 1/43) in ascending type (P<0.05). There were no statistically significant differences in the hearing curves of the declining type and other types between the two groups (P>0.05). (3) The proportion of imaging assessment without abnormality was significantly more common in the UAN group (81.8%) than in the SSD group (37.1%) (χ²=6.695, P=0.015). Conclusions: Compared to children with SSD, the occurrence of wave IIIL on the ABR test was significantly more common in children with UAN. The percentage of ascending hearing curves was significantly higher in children with UAN than in children with SSD. ASSR thresholds were significantly lower in children with UAN. The normal imaging phenotype was significantly more common in children with UAN than in children with SSD.

BACKGROUND: The surgical treatment of otosclerosis consists of the replacement of the stapes using a piston. AIMS/OBJECTIVES: The objective of this study is to assess the audiometric results and quality of life (QOL) of patients who underwent surgery for otosclerosis by stapedectomy with fascia interposition (STIP) or by stapedotomy using CO2 laser (SLaser) without fascia interposition. MATERIAL AND METHODS: Ninety-one patients operated on for otosclerosis by STIP (40 patients) and by SLaser (51 patients) were included. Audiometric results were graphically displayed using the Amsterdam Hearing Evaluation Plot and were compared to the Common Otology Database (COD) comprising 660 patients. The patients' QOL was assessed with an otological validated survey. The significance level was p < .05. RESULTS: There was no significant difference in hearing improvement between SLaser and STIP-operated patients. There was no significant difference between our results and that of COD. QOL was significantly improved (+3.5/10) postoperatively for both STIP and SLaser in both social and professional fields. CONCLUSIONS AND SIGNIFICANCE: By comparing QOL and hearing gain of STIP and SLaser, our results suggest that both surgical techniques are a safe and successful treatment for otosclerotic stapes fixation. Further studies aiming at comparing larger series may confirm and refine these results.

Introducción: Pese a que el uso de corticoides transtimpánicos en pacientes con enfermedad de Méniere es habitual en muchos centros, la evidencia respecto de su efecto sobre los umbrales auditivos es aún controversial. Objetivo: Estudiar los umbrales auditivos de pacientes con enfermedad de Méniere que recibieron corticoides transtimpánicos en el Servicio de Otorrinolaringología del Hospital Clínico de la Universidad de Chile. Material y Método: Estudio retrospectivo de pacientes con enfermedad de Méniere que consultaron entre los años 2015 y 2021. Se estudiaron los umbrales auditivos, antes y después de 3 inyecciones de dexametasona transtimpánica. Resultados: Se obtuvieron datos completos de 27 pacientes. Al comparar el promedio tonal puro antes y después del tratamiento, no se observaron diferencias significativas. A nivel individual, la variación de cambio de los umbrales auditivos con dexametasona se correlaciona en forma significativa con los umbrales auditivos previos a las inyecciones y con el tiempo transcurrido desde la última inyección, pero no con la edad. Conclusión: La terapia con dexametasona transtimpánica en pacientes con enfermedad de Méniere no altera los umbrales auditivos. Sin embargo, se requieren más estudios, para comprobar, si existe un efecto transitorio en los umbrales auditivos de los primeros días posterior al procedimiento.
Introduction: Although transtympanic corticosteroids are proposed in Méniere's disease patients refractory to standard medical therapy, the evidence regarding the effect of transtympanic corticosteroids on hearing thresholds is still controversial. Aim: To study the hearing thresholds of patients with Méniere's disease who were administrated with transtympanic corticosteroids at the Otorhinolaryngology Service of the University of Chile's Clinical Hospital. Material and Method: Retrospective study of Méniere's disease patients who consulted between 2015 and 2021. Demographic variables and hearing thresholds were studied before and after three transtympanic injections of dexamethasone. Results: A total of 27 patients were studied. There were non-significant differences in pure-tone hearing threshold averages before and after the injections. Individual variation in hearing thresholds correlates significantly with the pre-injection hearing thresholds and the period since the last injection, but not with age. Conclusion: Transtympanic dexamethasone therapy in patients with Meniere's disease does not alter hearing thresholds. However, more studies are needed to verify whether there is a transitory effect on hearing thresholds in the first days after the procedure.

Introducción: El envejecimiento de la población, así como la ampliación en las indicaciones de implantación, hace que cada día haya más pacientes implantados mayores de 65 años, lo que supone un reto a nivel de ajuste y optimización auditiva. Se ha constatado que la implantación coclear en pacientes de edad avanzada generalmente conduce a una mejoría, tanto auditiva como en la neurocognición, la depresión, el aislamiento social, la actividad física y la calidad de vida. Objetivo: Los objetivos de este estudio son valorar las características de los pacientes implantados a partir de 65 años en un centro terciario, analizar los beneficios e identificar particularidades clínicas en este grupo de pacientes. Material y Método: Se llevó a cabo un estudio retrospectivo con un seguimiento de 5 años postcirugía de pacientes con implante MED-EL y se realizó una visita preoperatoria y un seguimiento con audiometría en campo libre y audiometría verbales postquirúrgica al año, 3 años y 5 años postquirúrgico. Resultados: Se incluyó a 16 pacientes implantados unilateralmente. La edad media inicio pérdida fue de 36,75 años. La edad media de cirugía fue de 71,44 años. Los resultados auditivos fueron satisfactorios, con una media de audiometría en campo libre de 44,33 dB al año, 43,33 dB a los 3 años y 41,66 dB a los 5 años. El resultado en las audiometrías verbales (test de bisílabos y test de frases) fue mejor en el grupo de pacientes con adaptación bimodal. Conclusión: En nuestra experiencia, la implantación coclear en ≥65 años sí que logra mejorar las capacidades auditivas medidas, tanto en audiometría de campo libre como en pruebas verbales. La adaptación bimodal mejora los resultados auditivos, a pesar de la dificultad de procesamiento de los dos estímulos diferentes.
Introduction: The aging of the population, as well as the expansion in the indications for implantation means that every day there are more implanted patients over 65 years of age, which represents a challenge in terms of hearing adjustment and optimization. Cochlear implantation in elderly patients has been found to generally lead to improvements in hearing and neurocognition, depression, social isolation, physical activity, and quality of life. Aim: The objectives of this study are to assess the characteristics of patients over 65 years of age implanted in a tertiary center, analyze the benefits and identify clinical particularities in this group of patients. Material and Method: A retrospective study was carried out with a 5-year post-surgery follow-up of patients with a MED-EL implant, and a preoperative visit and follow-up with free-field audiometry and post-surgical speech audiometry were performed at one year, 3 years and 5 years post-surgery. Results: Sixteen unilaterally implanted patients were included. The mean age at onset of loss was 36.75 years. The mean age at surgery was 71.44 years. Hearing results were satisfactory, with a mean free field audiometry of 44.33 dB at one year, 43.33 dB at 3 years, and 41.66 dB at 5 years. The result in the verbal audiometries (disyllable test and sentence test) was better in the group of patients with bimodal adaptation. Conclusión: In our experience, cochlear implantation in patients ≥ 65 years of age does manage to improve hearing capacities measured both in free-field audiometry and in verbal tests. Bimodal adaptation improves auditory results, despite the difficulty ofprocessing the two different stimuli.

OBJECTIVE: To monitor ototoxicity, air conduction (AC) extended high frequency (EHF) thresholds can be measured up to 16 kHz. However, conductive hearing loss might influence these results. This is unfortunate because the EHF thresholds are important to follow the impact of ototoxic medication during therapy. Therefore a suitable bone conduction (BC) transducer and norm values for EHF BC measurements are needed. DESIGN: In this study three different BC transducers were used: the B71 (Radioear), the KH70 (Präcitronic), and the KLH96 (Westra). Hearing thresholds were measured from 0.125 to 16 kHz using AC transducers (Telephonics TDH39, Sennheiser HDA200), and BC thresholds from 0.25 to 8 kHz with the B71, and from 0.25 to 16 kHz with the KLH96 and KH70. STUDY SAMPLE: 60 ears of 30 normal hearing subjects were measured. RESULTS: The KLH96 showed the highest output for the high frequencies, and distortion measurements were similar to the KH70. The results show that EHF measurements are possible using the KLH96 and KH70 bone conductors. CONCLUSION: EHF BC measurements are reliable when using the KLH96 and KH70 bone conductors. The extended force sensitivity of the used artificial mastoid should be determined for a proper EHF BC calibration.

Introdução: A Diabetes Mellitus (DM) é um distúrbio metabólico causado pela ausência ou diminuição da secreção de insulina ou por alterações do funcionamento deste hormônio no organismo, podendo envolver alterações físicas e cognitivas. Objetivo: Analisar os aspectos audiológicos e cognitivos de adultos com Diabetes Mellitus tipo 2. Método: Estudo transversal realizado em pessoas com idade entre 18 e 59 anos, de ambos os gêneros. Os participantes foram divididos em dois grupos: Grupo Estudo (GE) - pessoas com diagnóstico de Diabetes Mellitus e o Grupo Controle (GC) - pessoas sem Diabetes. Todos foram submetidos à avaliação glicêmica, cognitiva e audiológica. Para análise estatística foi utilizado o teste de Mann-Whitney, sendo estipulado o nível de significância de 0,05. Resultados: Participaram do estudo 32 indivíduos sendo 19 (59,4%) no GE e 13 (40,6%) no GC. A média de idade dos participantes foi de 46,8 ± 8,3 anos, com escolaridade média de 6,8 ± 6 anos, sendo 25 (78,1%) do gênero feminino e 7 (21,9%) do masculino. Foi observada diferença estatisticamente significativa entre os grupos para a pontuação referente à atenção e cálculo, recordação e escore total do MEEM, com pior desempenho no GE. Não foi observada diferença estatisticamente significante entre os grupos nos aspectos audiológicos avaliados. Conclusão: Indivíduos com Diabetes Mellitus tipo 2 não apresentaram riscos para alterações audiológicas com os instrumentos utilizados, entretanto apresentaram um alto risco para alterações cognitivas. Os achados demonstram que o acompanhamento fonoaudiológico constante é essencial para identificar as alterações precocemente.
Introduction: Diabetes Mellitus (DM) is a metabolic disorder caused by the absence or reduction of insulin secretion or by changes in the functioning of this hormone in the body, which may involve physical and cognitive changes. Objective: To analyze the audiological and cognitive aspects of type 2 Diabetes Mellitus in adults. Method: Cross-sectional study carried out in people aged between 18 and 59 years, of both genders. Participants were divided into two groups: Study Group (SG) - people diagnosed with Diabetes Mellitus and the Control Group (CG) - people without Diabetes. All underwent glycemic, cognitive and auditory assessment. Mann-Whitney's test was used for statistical analysis, with a significance level of 0.05. Results: 32 individuals participated in the study, 19 (59.4%) in the EG and 13 (40.6%) in the CG. The mean age of the participants was 46.8 ± 8.3 years, with a mean education of 6.8 ± 6 years, with 25 (78.1%) females and 7 (21.9%) males. A statistically significant difference was observed between the groups for the score related to attention and calculation, recall and total Mini-Mental State Examination (MMSE) score, with worse performance in the EG. There was no statistically significant difference between the groups regarding the audiological aspects evaluated. Conclusion: Individuals with type 2 Diabetes Mellitus did not present risks for audiological alterations, however they presented a high risk for cognitive alterations. the findings demonstrate that constant speech therapy monitoring is essential to identify changes early.

During the COVID-19 pandemic, the utility of portable audiometry became more apparent as elective procedures were deferred in an effort to limit exposure to health care providers. Herein, we retrospectively evaluated mobile-based audiometry in the emergency department and outpatient otology and audiology clinics. Air conduction thresholds with mobile audiometry were within 5 dB in 66% of tests (95% CI, 62.8%-69.09%) and within 10 dB in 84% of tests (95% CI, 81.4%-86.2%) as compared with conventional audiometry. No significant differences were noted between mobile-based and conventional audiometry at any frequencies, except 8 kHz (P < .05). The sensitivity and specificity for screening for hearing loss were 94.3% (95% CI, 91.9%-96.83%) and 92.3% (95% CI, 90.1%-94.4%), respectively. While automated threshold audiometry does not replace conventional audiometry, mobile audiometry is a promising screening tool when conventional audiometry is not available.

"Cookie-bite" or U-shaped audiograms-specifically, those showing midfrequency sensorineural hearing loss (HL)-are traditionally taught to be associated with genetic HL; however, their utility as a screening tool has not been reported. We aim to determine the performance of a cookie-bite audiogram shape in stratifying patients carrying putative loss-of-function variants in known HL genes from wild-type controls. We merged audiometric and exome sequencing data from adults enrolled in a large biobank at a tertiary care center. Of 321 patients, 50 carried a putative loss-of-function variant in an HL gene. The cookie-bite shape was present in 9 of those patients, resulting in low sensitivity (18%) and positive predictive value (15%) in stratifying genetic carrier status; 84% of patients with a cookie-bite audiogram did not carry a genetic variant. A cookie-bite audiogram should not be used to screen adults for possible genetic testing.

BACKGROUND: Childhood hearing loss is a global epidemic most prevalent in low- and middle-income countries where hearing healthcare services are often inaccessible. Referrals for primary care services to central hospitals add to growing lists and delays the time-sensitive treatment of childhood hearing loss. AIM: To compare a centralised tertiary model of hearing healthcare with a decentralised model through district hearing screening for children in the Western Cape province, South Africa. SETTING: A central paediatric tertiary hospital in Cape Town and a district hospital in the South Peninsula region. METHODS: A pragmatic quasi-experimental study design was used with a 7-month control period at a tertiary hospital (June 2019 to December 2019). Decentralising was measured by attendance rates, travelling distance, number of referrals to the tertiary hospital and hearing outcomes. There were 315 children in the tertiary group and 158 in the district group. Data were collected from patient records and an electronic database at the tertiary hospital. RESULTS: Attendance rate at the district hospital was significantly higher (p 0.001). Travel distance to the district hospital was significantly shorter (p 0.001). Number of referrals to the tertiary hospital decreased significantly during the intervention period (p 0.001). Most children in both the tertiary and district groups (78.7% and 80.4%, respectively) passed initial hearing screening bilaterally. CONCLUSION: Hearing screening should be conducted at the appropriate level of care to increase access, reduce patient travelling distances and associated costs and reduce the burden on tertiary-level hospitals.

BACKGROUND/AIM: Chemopreventative therapeutics may be helpful in familial adenomatous polyposis (FAP) management; however, prospective chemopreventative studies are complicated by potential ototoxicity and pre-existing hearing loss. The aim of this study was to establish and compare baseline hearing status of children and adolescents with FAP and their unaffected siblings. PATIENTS AND METHODS: Twenty FAP pediatric patients with documented mutation of the adenomatous polyposis coli (APC) gene and nine unaffected sibling controls underwent baseline hearing evaluation, including audiometry, speech perception testing, and middle and inner ear physiologic measures. Results of the FAP cohort were compared to the unaffected sibling cohort. RESULTS: Two (5%) children with FAP presented with baseline hearing loss of unknown etiology, likely unrelated to their FAP diagnosis. No significant differences were found in any of the hearing measures between groups. CONCLUSION: Mutation of the APC gene is not necessarily indicative of higher risk for baseline hearing loss in the pediatric population.

Importance: Accurate assessment of hearing is critically important regardless of a person's cognitive ability. The degree to which hearing can be reliably measured in adults with mild dementia has not been determined. Objective: To obtain quantitative measures of reliability to evaluate the degree to which audiologic testing can be accurately conducted in older adults with mild dementia. Design, Setting, and Participants: This repeated-measures cross-sectional study consisted of a comprehensive audiologic assessment on 2 occasions separated by 1 to 2 weeks performed in the department of otolaryngology at the Washington University School of Medicine from December 3, 2018, to March 4, 2020. Participants were 15 older adults with a verified diagnosis of mild dementia and 32 older adults without a verified diagnosis of mild dementia who were recruited from the Knight Alzheimer Disease Research Center at Washington University in St Louis. Main Outcomes and Measures: Test-retest reliability was assessed for tympanometry, acoustic reflex thresholds, otoacoustic emissions, hearing sensitivity, speech reception threshold, speech perception in noise, and hearing handicap, using standard clinical audiology measures. Results: A total of 47 older adults (26 women; mean [SD] age, 74.8 [6.0] years [range, 53-87 years]), including 32 with normal cognitive function and 15 with very mild or mild dementia, completed the study protocol. For participants with mild dementia, high test-retest reliability (Spearman ρ > 0.80) was found for most measures typically included in a comprehensive audiometric evaluation. For acoustic reflex thresholds, agreement was moderate to high, averaging approximately 83% across frequencies for both groups. Scores for the screening Hearing Handicap Inventory for the Elderly at time 1 and time 2 were highly correlated for the group with normal cognitive function (r = 0.84 [95% CI, 0.70-0.93]) and for the group with mild dementia (r = 0.96 [95% CI, 0.88-0.99]). For hearing thresholds, all rank-order correlations were above 0.80 with 95% CIs at or below 15% in width, with the exception of a moderate correlation of bone conduction thresholds at 500 Hz for the group with normal cognitive function (r = 0.69 [95% CI, 0.50-0.84]) and slightly wider 95% CIs for low-frequency bone conduction thresholds for both groups. For speech reception thresholds, correlations were high for groups with normal cognitive function (r = 0.91 [95% CI, 0.84-0.95]) and mild dementia (r = 0.83 [95% CI, 0.63-0.94]). Conclusions and Relevance: Test-retest reliability for hearing measures obtained from participants with mild dementia was comparable to that obtained from cognitively normal participants. These findings suggest that mild cognitive impairment does not preclude accurate audiologic assessment.

OBJECTIVE: To emphasize the benefits of tele-otology in community screening of patients with ear diseases. METHODS: A retrospective study of all patients screened and treated under the Shruti tele-otology program between 2013 and 2019 was conducted. It involved screening, diagnosis, medical management, surgical intervention, and rehabilitation using hearing aid. The study focused on underprivileged and underserved community of rural and urban slums across 12 states of India. The study was conducted using a telemedicine device called ENTraview, that is, a camera-enabled android phone integrated with an otoscope and audiometry screening. RESULT: A total of 810 746 people were screened, and incidence of various ear diseases was recorded. Ear problems were found in 265 615 (33%) patients, of which 151 067 (57%) had impacted wax, 46 792(18%) had chronic suppurative otitis media, 27 875 (10%) had diminished hearing, 12 729 (5%) had acute otitis media and acute suppurative otitis media (ASOM), and 27 152 (10%) had problems of foreign body, otomycosis, and so on. Of the total 265 615 referred patients, 20 986 (8%) reported for treatment and received treatment at a significantly reduced cost through Shruti program partners. The conversion rate of nonsurgical and surgical procedure was also compared, and it was found that, while 9% of the patients opted for nonsurgical treatment, only 3% opted for surgery in the intervention group giving a significant P value of .00001. CONCLUSION: The potential for telemedicine to reduce inequalities in health care is immense but remains underutilized. Shruti has largely been able to bridge this gap as it is an innovative, fast, and effective programs that address the ear ailment in the community.

OBJECTIVES: Access to diagnosis and treatments for auditory disorders and related pathologies has regressed in France during the COVID-19 pandemic, posing a risk to the patient's chance of recovery. This best practice recommendations guide aims to list the existing technological solutions for the remote examination of a patient with hearing complaint, and to outline their benefits and, where applicable, their limitations. METHODS: The recommendations were developed both from the clinical experience of the medical experts who drafted the guide, and from an extensive review of the literature dealing with clinical practice recommendations for tele-audiology. Tele-audiometry solutions were identified on the basis of a search engine query carried out in April 2020, prior to verification of their availability on the European market. RESULTS: Video otoscopy solutions allow for the teletransmission of images compatible with a high-quality diagnosis, either by connecting via internet to a tele-health platform or using a smartphone or a tablet with an iOS or Android operating system. Using the same telecommunication methods, it is possible to remotely conduct a pure-tone audiometry test in accordance with standard practice, a speech-in-quiet or a speech-in-noise audiometry test, as well as objective measures of hearing. Clinical and paraclinical examinations can be accessed by the physician to be interpreted on a deferred basis (asynchronous tele-audiology). Examinations can also be conducted in real time in a patient, at any age of life, as long as a caregiver can be present during the installation of the transducers or the acoumetry. Tele-audiology solutions also find application in the remote training of future healthcare professionals involved in the management of deafness and hearing impairment. CONCLUSION: Under French law, tele-otoscopy is a medical procedure that is either a tele-expertise (asynchronous adive) or a teleconsultation act (synchronous advice). Subjective and objective evaluation of the patient's hearing functions can be done remotely provided that the listed precautions are respected.

BACKGROUND: We have investigated the main genetic causes for non-syndromic hearing impairment (NSHI) in the hearing impairment individuals from the North-Eastern Romania and proposed a cost-effective diagnosis protocol. METHODS: MLPA followed by Sanger Sequencing were used for all 291 patients included in this study. RESULTS: MLPA revealed abnormal results in 141 cases (48.45%): 57 (40.5%) were c.35delG homozygous, 26 (18.44%) were c.35delG heterozygous, 14 (9.93%) were compound heterozygous and 16 (11.35%) had other types of variants. The entire coding region of GJB2 was sequenced and out of 150 patients with normal results at MLPA, 29.33% had abnormal results: variants in heterozygous state: c.71G>A (28%), c.457G>A (20%), c.269T>C (12%), c.109G>A (12%), c.100A>T (12%), c.551G>C (8%). Out of 26 patients with c.35delG in heterozygous state, 38.46% were in fact compound heterozygous. CONCLUSIONS: We identified two variants: c.109G>A and c.100A>T that have not been reported in any study from Romania. MLPA is an inexpensive, rapid and reliable technique that could be a cost-effective diagnosis method, useful for patients with hearing impairment. It can be adaptable for the mutation spectrum in every population and followed by Sanger sequencing can provide a genetic diagnosis for patients with different degrees of hearing impairment.

Emergency departments (EDs) are a common location for patients to present with sudden hearing loss (SHL). Unfortunately, high-quality, rapid quantitative measurement of hearing loss is challenging. Herein, we aim to evaluate the accuracy of tablet-based audiometry in patients complaining of SHL. Prospective tablet-based testing was completed in the ED in patients complaining of SHL. Air conduction thresholds (ACTs) obtained via tablet-based audiometry were compared to same-day measurements with a clinical-grade audiometer. Hearing loss (HL) was defined as >20 dB ACT for any frequency. In participant-level analysis, 30+ dB HL in 3 consecutive frequencies was used to define SHL. In the ED, mobile audiogram ACTs were within 5 dB (77%) and 10 dB (89.6%) of those determined by conventional audiometry. The sensitivity and specificity for mobile audiometry to detect 3 or more consecutive thresholds with 30+ dB HL were 100% and 62.5%, respectively. Findings have implications for increasing access to high-quality audiometry.

BACKGROUND: Ectopic intracranial schwannomas (those that do not arise from a named cranial nerve) are rare. They account for <2% of surgically resected central nervous system schwannomas. CASE DESCRIPTION: We report the case of a 14-year-old boy presenting with a left conductive hearing loss and temporal bone deformity. No facial or cranial nerve deficits were present. Cross-sectional imaging demonstrated a large expansile extra-axial temporal bone mass, extending into and distorting the middle cranial fossa. At surgical resection the tumor was functionally and anatomically distinct from the facial nerve or any other identifiable neural structure within the middle ear or temporal bone. Histology confirmed a World Health Organization grade 1 schwannoma. CONCLUSIONS: This is the first reported case of a giant juvenile ectopic schwannoma within the temporal bone.

OBJECTIVE: To investigate audiometric outcomes and incidence of chronic ear disease following lateral skull base repair (LSBR) of cerebrospinal fluid (CSF) leaks. STUDY DESIGN: Retrospective review. SETTING: Tertiary skull base center. SUBJECTS AND METHODS: Consecutive adults undergoing LSBR of CSF leaks between 2012 and 2018 were reviewed. Audiometric data included mean air conduction pure-tone average (PTA), air-bone gap (ABG), speech recognition threshold (SRT), and word recognition score (WRS). The incidence and management of the following were collected: effusion, retraction, otitis media and externa, perforation, and cholesteatoma. RESULTS: Seventy-three patients underwent transmastoid (n = 5), middle cranial fossa (n = 2), or combined approach (n = 67) for repair of spontaneous leaks (sCSFLs, n = 41) and those occurring in the setting of chronic ear disease (ceCSFLs, n = 32). ABG decreased 7.23 dB (P = .01) in sCSFL patients. Perforations (P = .01) were more likely in ceCSFL. No sCSFL patient developed a cholesteatoma, perforation, or infection. Effusions (n = 7) were transient, and retractions (n = 2) were managed conservatively in the sCSFL cohort. Eight ceCSFL patients required tubes, 3 underwent tympanoplasties with (n = 2) and without (n = 1) ossicular chain reconstruction (OCR), and 1 had tympanomastoidectomy with OCR. CONCLUSION: Lateral skull base repair of CSF leaks maintained or improved hearing. Patients with preexisting chronic ear disease were more likely to require additional intervention to sustain adequate middle ear aeration compared to the sCSFL cohort. LSBR of sCSFL does not appear to increase risk for developing chronic ear disease.

BACKGROUND: We field tested new-to-market portable, digital applications to assess hearing, pulmonary, and cognitive function to determine the feasibility of implementing these applications across a range of age groups in the pilot phase of the 10,000 Families Study (10KFS), a new Minnesota family-based prospective cohort study. METHODS: We followed manufacturer recommended protocols for audiometry (SHOEBOX Inc), spirometry (NuvoAir), and the digital clock drawing test (dCDT; Digital Cognition Technologies Inc). RESULTS: These digital devices were low cost and readily implemented in a 2.5-hour health fair visit with minimal training (2-3 hours) of study staff. To date, we have performed these measurements on 197 eligible 10KFS participants during an in-person clinic visit. A total of 37 children (age 4-17 years), 107 adults (18-64 years), and 53 seniors (≥65 years) were eligible to undergo hearing and pulmonary assessments. Children were less likely to successfully complete the hearing test (76%) compared with adults (86%) and seniors (89%). However, successful completion of the pulmonary assessment was high across all groups: 100% of children and seniors and 98% of adults. The dCDT was performed among those over the age of 40, and completion rates were 92% for those aged 41-64 and 94% for those ≥65 years. CONCLUSIONS: Our field testing indicates these digital applications are easy and cost-effective to implement in epidemiologic studies. IMPACT: Digital applications provide exciting opportunities to collect data in population studies. Issues related to data privacy, data access, and reproducibility of measurements need to be addressed before deploying digital applications in epidemiologic studies.See all articles in this CEBP Focus section, "Modernizing Population Science."

INTRODUCCIÓN: Recientes investigaciones mencionan que, debido a los altos niveles de ruidos, el 75% de los habitantes en las ciudades industrializadas padecen algún tipo de deficiencia auditiva. La audiometría de alta frecuencia es un examen complementario importante para detectar tempranamente la pérdida de audición. OBJETIVO: Determinar la utilidad diagnóstica de la audiometría de alta frecuencia en la detección temprana de la hipoacusia en sujetos expuestos a ruido recreacional. MATERIAL Y MÉTODO: Estudio analítico de corte transversal. Se evaluaron 87 estudiantes de fonoaudiología. Se aplicó una audiometría convencional y de alta frecuencia mediante audiómetro clínico. RESULTADOS: La audiometría de alta frecuencia presenta una sensibilidad del 100%, especificidad del 64,60%. El valor predictivo (+) es de 14,70%, mientras que el valor predictivo (-) es del 100%. La razón de verosimilitud (+) es de 2,28, y para la razón de verosimilitud (-) es de 0,0. CONCLUSIÓN: La audiometría de alta frecuencia puede ser utilizada para monitorizar la audición de los sujetos, comprobando que efectivamente los umbrales auditivos de alta frecuencia se encuentren dentro de rangos normales. Lo anterior, dado por sus valores de sensibilidad, valor predictivo negativo, razón de verosimilitud negativa y por el aumento entre la probabilidad preprueba y posprueba.
INTRODUCTION: Recent research mentions that, due to the high noise levels, 75% of the habitants in industrialized cities suffer from some type of hearing impairment. High frequency audiometry is an important complementary test to detect early hearing loss. AIM: To determine the diagnostic utility of high frequency audiometry in the early detection of hearing loss in subjects exposed to recreational noise. MATERIAL AND METHODS: Study analytical type and cross section. 87 speech therapy students were evaluated. A conventional and high frequency audiometry was applied, using a clinical audiometer. RESULTS: High frequency audiometry has a sensitivity of 100%, specificity of 64,60%. The predictive value (+) is 14,70%, while the predictive value (-) is 100%. The likelihood ratio (+) is 2,28, and for the likelihood ratio (-) it is 0,0. CONCLUSION: High frequency audiometry can be used to monitor the hearing of the subjects, checking that effectively the high frequency hearing thresholds are within normal ranges. The above, given by their values of sensitivity, negative predictive value, negative likelihood ratio and the increase between the pre-test probability and the posttest probability.
