RESUMEN
OBJECTIVES: Hearing loss (HL) is one of the most common chronic health conditions in the United States (US). This study aims to evaluate trends in HL prevalence among US adults over the past two decades. METHODS: Audiometric data of adults from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018 were analyzed in 2-year intervals to evaluate changes in HL (defined as pure tone average greater than 25 dB in at least one ear) over time in using odds ratios (ORs). Multivariate logistic regression was used to control for age and sex, and linear regression was used to evaluate trends in HL prevalence over time. RESULTS: The study included 13,468 participants. In adult participants (20-69 years old), HL remained stable over time, with some fluctuations ranging from 14.8% to 16.8%. In elderly participants (70-years and older), HL remained stable over time, with some fluctuations ranging from 71.7% to 77.1%. Based on univariate and linear regression analysis, there were no differences in HL rates in the adult and elderly cohorts. Subjects 40-49 years old and adults with education level of less than high school had significant downward trends in HL prevalence over two decades (p < 0.001 and p = 0.029). CONCLUSIONS: HL prevalence may be declining in the adult population when correcting for age and gender; however, there has not been a significant downward trend for the elderly population. HL may be decreasing over time among adults 40-49 years old and with shorter education backgrounds. LEVEL OF EVIDENCE: IV Laryngoscope, 2024.
RESUMEN
Background: Oxidative stress is associated with the occurrence of hearing loss and tinnitus. The oxidative balance score (OBS), a composite indicator evaluating the balance between antioxidant and pro-oxidative components across various dietary and lifestyle factors, indicates the overall oxidative balance status. However, the association of OBS with hearing loss and tinnitus has not been reported previously. Methods: Cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 were analyzed. Weighted multivariable logistic regression, weighted multivariable linear regression, and restricted cubic spline curve (RCS) regression were employed to explore the relationship between OBS and hearing loss at speech, low, and high frequencies, along with tinnitus. Subgroup analysis and sensitivity analysis were used to ascertain the consistency across subgroups and stability of the results. Results: We included 13,715 and 21,644 individuals to investigate the association between OBS and hearing loss, as well as between OBS and tinnitus, respectively. The second, third, and fourth quartiles of OBS were significantly associated with a lower risk of hearing loss at speech, low, and high frequencies, as well as tinnitus, compared to the lowest quartile. The RCS regression analysis indicated a negative linear association of OBS with hearing loss and tinnitus. Most associations were maintained in subgroup analysis and sensitivity analysis. Additionally, the dietary and lifestyle OBS independently contribute to the protection against hearing loss and tinnitus. Conclusion: OBS is negatively correlated with the risk of hearing loss and tinnitus. The findings suggest that combined antioxidant diet and lifestyle hold promise as potential strategies for reducing the prevalence of hearing loss and tinnitus.
RESUMEN
BACKGROUND: Audiological diagnosis and rehabilitation often involve the assessment of whether the maximum speech identification score (PBmax) is poorer than expected from the pure-tone average (PTA) threshold. This requires the estimation of the lower boundary of the PBmax values expected for a given PTA (one-tailed 95% confidence limit, CL). This study compares the accuracy and consistency of three methods for estimating the 95% CL. METHOD: The 95% CL values were estimated using a simulation method, the Harrell-Davis (HD) estimator, and non-linear quantile regression (nQR); the latter two are both distribution-free methods. The first two methods require the formation of sub-groups with different PTAs. Accuracy and consistency in the estimation of the 95% CL were assessed by applying each method to many random samples of 50% of the available data and using the fitted parameters to predict the data for the remaining 50%. STUDY SAMPLE: A total of 642 participants aged 17 to 84 years with sensorineural hearing loss were recruited from audiology clinics. Pure-tone audiograms were obtained and PBmax scores were measured using monosyllables at 40 dB above the speech recognition threshold or at the most comfortable level. RESULTS: For the simulation method, 6.7 to 8.2% of the PBmax values fell below the 95% CL for both ears, exceeding the target value of 5%. For the HD and nQR methods, the PBmax values fell below the estimated 95% CL for approximately 5% of the ears, indicating good accuracy. Consistency, estimated from the standard deviation of the deviations from the target value of 5%, was similar for all the methods. CONCLUSIONS: The nQR method is recommended because it has good accuracy and consistency, and it does not require the formation of arbitrary PTA sub-groups.
RESUMEN
OBJECTIVE: To investigate the predictive factors of long-term hearing threshold and temporal bone development in children with congenital microtia (CM). METHODS: 74 patients (92 ears) with CM enrolled, which all had auditory brainstem response (ABR) results during infancy or toddlerhood, pure tone audiometry (PTA) and high-resolution computed tomography (HRCT) results during childhood or adolescence, and had not undergone any surgery. We compared the relationship between ABR, auditory steady-state response (ASSR), the affected side, auricular morphology, presence of external auditory canal stenosis or atresia, PTA average, mastoid pneumatization, Jarhsdoerfer scores, and wether cholesteatoma exists. RESULTS: The average age of ABR in 92 ears was 2.72 ± 3.52 years old, PTA was 7.26 ± 2.51 and HRCT was 6.91 ± 2.76 years old. ABR-AC was related to PTA average, mastoid pneumatization, Jarhsdoerfer scores, and wether cholesteatoma exists in CM. While ABR-ABG was related to all of these factors except Jarhsdoerfer score, and ABR-BC had no relationship with any of them. ASSR only showed correlation with frequencies of 1, 2 kHz and was related to Jarhsdoerfer score, with no other correlations observed. The impaired ear side showed no relevance. However, auricular morphology was related to all of these factors except wether cholesteatoma exist. External auditory canal stenosis or atresia was related to PTA average, but unrelated to mastoid pneumatization. CONCLUSION: The ABR examination in the infant stage plays a crucial role in predicting the long-term hearing and temporal bone development in patients with CM.

OBJECTIVES: Social determinants of health (SDH) are nonmedical, societal factors that influence health. There is limited information on the current relationship between SDH and hearing loss (HL) in the United States. This study aims to compare the odds of HL among US adults by race/ethnicity, education level, income-to-poverty level ratio, health insurance coverage, and health care access. STUDY DESIGN: Cross-sectional study. METHODS: The 2015-2020 National Health and Nutrition Examination Survey data were analyzed to compare odds ratios (ORs) for HL, defined as pure tone average over 25 dB HL in at least one ear, by SDH categories using sample weights. Adjusted ORs were calculated using logistic regression models controlling for sex, age, race/ethnicity, education level, income-to-federal-poverty level, health care insurance coverage and access, and loud noise, pesticide, and cigarette exposure. RESULTS: A total of 6028 participants were included. Non-Hispanic Black participants had half the odds of HL as Non-Hispanic White participants (OR 0.52, p < 0.05). Lower education level correlated with higher odds of HL: those without a high school diploma had double the odds of HL compared with college graduates or above (OR 2.05, 1.91, p < 0.05). The income-to-federal-poverty level ratio of 1.3 to less than 2 had higher odds of HL than the 4+ group (OR 1.45, p < 0.05). Use of multiple health care locations was associated with nearly three times the odds of HL than the group using one location (OR 2.87, p < 0.05). CONCLUSION: SDH are associated with HL. Further investigation is needed into the mechanism of disparities for targeted prevention and treatment for hearing care equity. LEVEL OF EVIDENCE: IV Laryngoscope, 134:2848-2856, 2024.

Electric stimulation via a cochlear implant (CI) enables people with severe-to-profound sensorineural hearing loss to regain speech understanding and music appreciation and, thus, allow them to actively engage in social life. Three main manufacturers (CochlearTM, MED-ELTM, and Advanced BionicsTM "AB") have been offering CI systems, thus challenging CI recipients and otolaryngologists with a difficult decision as currently no comprehensive overview or meta-analysis on performance outcomes following CI implantation is available. The main goals of this scoping review were to (1) map the literature on speech and music performance outcomes and to (2) find whether studies have performed outcome comparisons between devices of different manufacturers. To this end, a literature search was conducted to find studies that address speech and music outcomes in CI recipients. From a total of 1592 papers, 188 paper abstracts were analyzed and 147 articles were found suitable for an examination of full text. From these, 42 studies were included for synthesis. A total of 16 studies used the consonant-nucleus-consonant (CNC) word recognition test in quiet at 60 db SPL. We found that aside from technical comparisons, very few publications compared speech outcomes across manufacturers of CI systems. However, evidence suggests that these data are available in large CI centers in Germany and the US. Future studies should therefore leverage large data cohorts to perform such comparisons, which could provide critical evaluation criteria and assist both CI recipients and otolaryngologists to make informed performance-based decisions.
RESUMEN
This article reviews the research of Pat Stelmachowicz on traditional and novel measures for quantifying speech audibility (i.e., pure-tone average [PTA], the articulation/audibility index [AI], the speech intelligibility index, and auditory dosage) as predictors of speech perception and language outcomes in children. We discuss the limitations of using audiometric PTA as a predictor of perceptual outcomes in children and how Pat's research shed light on the importance of measures that characterize high-frequency audibility. We also discuss the AI, Pat's work on the calculation of the AI as a hearing aid outcome measure, and how this work led to the application of the speech intelligibility index as a clinically utilized measure of unaided and aided audibility. Finally, we describe a novel measure of audibility-auditory dosage-that was developed based on Pat's work on audibility and hearing aid use for children who are hard of hearing.
RESUMEN
Introducción y objetivos: La sordera súbita idiopática se define habitualmente, como una pérdida auditiva superior o igual a 30 dB HL, en 3 o más frecuencias consecutivas, con un tiempo de instauración inferior a 72 horas, de causa desconocida. Siendo actualmente motivo de discusión el efecto de la terapia esteroidea en este síndrome, evaluaremos la eficacia del corticoide intratimpánico (CIT) como tratamiento de rescate. Como objetivo secundario, estudiaremos la influencia de determinados factores considerados de riesgo o pronóstico. Pacientes y métodos: Se comparan los resultados de dos grupos de población con edad y pérdida auditiva similar. El primero, de 99 pacientes, recibió exclusivamente tratamiento sistémico con corticoides. En el segundo de 70, con una sordera súbita idiopática refractaria al tratamiento general, instilamos corticoide intratimpánico. Comparamos las diferencias de umbral medio auditivo en el momento del diagnóstico y a los 3 meses, además del grado general de recuperación. Resultados: La aplicación intratimpánica de 3 dosis de dexametasona (8mg/ml) en la sordera súbita idiopática refractaria, no ha producido, en nuestra población, un cambio significativo respecto al tratamiento sistémico. Analizamos también la influencia de los factores pronósticos seleccionados. Discusión: Desconocemos la eficacia del tratamiento con corticoides en la sordera súbita idiopática. El tipo de lesión y las características del paciente podrían ser decisivos en el pronóstico final y en el resultado terapéutico. Conclusiones: El tratamiento de rescate con CIT, no ha aportado mejoría auditiva significativa en la población estudiada. Los factores con peor pronóstico son: la presencia de síntomas vestibulares, la hipoacusia de grado profundo, la caída audiométrica hacia tonos agudos, el inicio del tratamiento después de 2 semanas y fundamentalmente, la falta de mejoría de al menos 10 dB el 4º día de tratamiento.

Introduction and objectives: Idiopathic Sudden Sensorineural Hearing Loss (ISSNHL) is commonly defined as greater than 30 dB of hearing loss in at least 3 audiometric frequencies occurring over 3 days or less, of unknown cause. Since the effect of steroid therapy in this syndrome is currently under discussion, we will evaluate the efficacy of intratympanic corticosteroid (ITC) as rescue treatment. As a secondary objective, we will study the influence of certain factors considered risk or prognostic. Patients and methods: The results of two population groups with similar age and hearing loss are compared. The first of 99 patients received exclusively systemic treatment with corticosteroids. In the second group of 70, with ISSNHL refractory to general treatment, we instilled intratympanic corticosteroids. We compared the differences in mean hearing threshold at diagnosis and at 3 months, as well as the general degree of recovery. Results: Intratympanic application of 3 doses of dexamethasone (8mg/ml) in refractory ISSNHL did not produce, in our population, a significant change with respect to systemic treatment. We also analyzed the influence of selected prognostic factors. Discussion: We do not know the efficacy of corticosteroid treatment in idiopathic sudden deafness. The type of lesion and patient characteristics could be decisive in the final prognosis and therapeutic outcome. Conclusions: Rescue treatment with ITC has not provided significant hearing improvement in the population studied. The factors with the worst prognosis are the presence of vestibular symptoms, profound hearing loss, high-frequency hearing loss in audiometry, the beginning of treatment after 2 weeks and fundamentally, the lack of improvement of at least 10 dB on the 4th day of treatment.

Tinnitus is a phantom sound perceived in the absence of external acoustic stimulation. It is described in a variety of ways (e.g., buzzing, ringing, and roaring) and can be a single sound or a combination of different sounds. Our study evaluated associations between audiological parameters and the presence or severity of tinnitus, to improve tinnitus diagnosis, treatment, and prognosis. Our sample included 122 older participants (63 women and 59 men), aged 55-75 years from the Portuguese population, with or without sensory presbycusis and with or without tinnitus. All participants underwent a clinical evaluation through a structured interview, Ear, Nose, and Throat observation, and audiological evaluation (standard and extended audiometry, psychoacoustic tinnitus evaluation, auditory brainstem responses, and distortion product otoacoustic emissions). The Tinnitus Handicap Inventory was used to measure tinnitus symptom severity. Our data confirmed that the odds of developing tinnitus were significantly higher in the presence of noise exposure and hearing loss. Also, participants who had abrupt tinnitus onset and moderate or severe hyperacusis featured higher odds of at least moderate tinnitus. However, it was in the ABR that we obtained the most exciting and promising results, namely, in wave I, which was the common denominator in all findings. The increase in wave I amplitude is a protective factor to the odds of having tinnitus. Concerning the severity of tinnitus, the logistic regression model showed that for each unit of increase in the mean ratio V/I of ABR, the likelihood of having at least moderate tinnitus was 10% higher. Advancing knowledge concerning potential tinnitus audiological biomarkers can be crucial for the adequate diagnosis and treatment of tinnitus.
RESUMEN
To assess the incidence and severity of changes in hearing threshold in patients undergoing high-dose pencil-beam-scanning proton therapy (PBS-PT). This retrospective cohort study included fifty-one patients (median 50 years (range, 13-68)) treated with PBS-PT for skull base tumors. No chemotherapy was delivered. Pure tone averages (PTAs)were determined before (baseline) and after PBS-PT as the average hearing thresholds at frequencies of 0.5, 1, 2, and 4 kHz. Hearing changes were calculated as PTA differences between pre-and post-PBS-PT. A linear mixed-effects model was used to assess the relationship between the PTA at the follow-up and the baseline, the cochlea radiation dose intensity, the increased age, and the years after PBS-PT. Included patients were treated for chordoma (n = 24), chondrosarcoma (n = 9), head and neck tumors (n = 9), or meningioma (n = 3), with a mean tumor dose of 71.1 Gy (RBE) (range, 52.0-77.8), and a mean dose of 37 Gy (RBE) (range, 0.0-72.7) was delivered to the cochleas. The median time to the first follow-up was 11 months (IQR, 5.5-33.7). The PTA increased from a median of 15 dB (IQR 10.0-25) at the baseline to 23.8 (IQR 11.3-46.3) at the first follow-up. In the linear mixed-effect model, the baseline PTA (estimate 0.80, 95%CI 0.64 to 0.96, p ≤ 0.001), patient's age (0.30, 0.03 to 0.57, p = 0.029), follow-up time (2.07, 0.92 to 3.23, p ≤ 0.001), and mean cochlear dose in Gy (RBE) (0.34, 0.21 to 0.46, p ≤ 0.001) were all significantly associated with an increase in PTA at follow-up. The applied cochlear dose and baseline PTA, age, and time after treatment were significantly associated with hearing loss after proton therapy.
RESUMEN
Background: This study mainly focus on hearing loss pattern in CSOM patients undergoing tympanoplasty surgery or tympanomastoidectomy pre-operatively and analysis of the outcome of the surgery in terms of improvement in hearing (air-bone gap) after 3 months of the surgery. Methodology: All patients of age 15-65 years reporting to ENT OPD with ear discharge and decreased hearing were screened with detailed history, clinical examination and microscopic examination.110 cases of tympanic membrane perforation who were fit for surgery were advised tympanoplasty or tympanoplasty with mastoidectomy. Results: Our study shows that postoperative air-bone gap closure is maximum for cortical mastoidectomy type I tympanoplasty (14.03 dB), followed with cortical mastoidectomy with type II (12.2 dB), Type I tympanoplasty (11 dB), cortical mastoidectomy with type III (7.72 dB). Procedures combined with modified radical mastoidectomy showed a very poor mean improvement in our study. Conclusion: It is very difficult to predict the results preoperatively because outcome will depend on extent of involvement of middle ear cleft by the disease process which can only be assessed intraoperatively.
RESUMEN
OBJECTIVES: The current study aimed to investigate if there is a difference in the use of intratympanic steroid therapy (IST), compared to systemic steroid treatment (SST), as an initial treatment for patients with sudden sensorineural hearing loss (SSNHL) by a meta-analysis design performed on the mean pure-tone average (PTA) improvement and the complete recovery rate. METHODS: A systematic literature review was performed on randomized controlled trials published from 1990 to August 2020 in some databases including PubMed/MEDLINE, Scopus, Embase, Web of Science, Cochrane library/CENTRAL, Ovid, ProQuest, Google Scholar, and clinical trials.gov. The primary outcomes of interest were pure-tone average improvement and complete recovery rates. RESULTS: Six eligible studies with 496 patients (250 patients in the IST group and 246 subjects in the SST group) were included in this study. The pooled standardized mean difference of the PTAs was estimated as 0.07 (95% CI = -0.10 to 0.25; I2 = 0.0%, P = 0.668), and the pooled odds ratio of complete recovery rate was obtained as 1.00 (95% CI = 0.66 to 0.151; I2 = 31.6, P = 0.199). Moreover, the pooled standardized mean difference of pure-tone average for the intratympanic steroid treatment group compared to the patients with oral steroid treatment was 0.07 (95% CI = -0.12 to 0.26; I2 = 0.0%, P = 0.526). CONCLUSIONS: The current study demonstrated that the effect of intratympanic injection of corticosteroid, as a first-line treatment, is not statistically different from the systemic route in improving the hearing outcomes among patients with SSNHL.

Background: Fabry disease (FD) is a lysosomal storage disorder resulting in systemic accumulation of globotriaosylceramide (Gb3) causing multi-organ dysfunction. The audiologic involvement in FD has been neglected in previous studies; while not a lethal aspect of the disease, hearing loss can have a significantly negative impact on quality of life. Objective: To investigate hearing loss from baseline through 16 years follow-up of the Danish FD cohort and to compare audiometric data to other clinical variables. Methods: Data was collected prospectively and assessed retrospectively during a period of 16 years from 83 patients (age: 9-72 years; sex: 29 males and 54 females). 55 patients underwent treatment. Air conduction thresholds was assessed at six frequencies between 0.25 and 8 kHz bilaterally. Data was analyzed using multilinear models. Results: Mean follow-up period for patients undergoing a FD specific treatment was 7.8 years (0-12.8 years, SD 3.8 years, n = 55). Hearing thresholds for FD patients deviated from healthy individuals at all frequencies for both sexes (p < 0.001). Males had more profound hearing loss than females at high frequencies (4,8 kHz) (p = 0.025). There was no improvement in hearing with treatment (p = 0.343â, p = 0.256â). No associations between hearing loss and measured glomerular filtration rate, left ventricular wall thickness or cerebral white matter lesions were found. Lower plasma Gb3 concentration correlated with better hearing (p = 0.046) in males. Conclusion: Our findings demonstrated significant hearing loss in FD patients compared to audiologically healthy individuals at all frequencies, and no change in hearing during treatment. Lower plasma Gb3 concentrations correlated with better hearing in males.
RESUMEN
PURPOSE: Obstructive sleep apnea (OSA) is characterized by recurring hypoxic-apneic events during sleep, and labyrinthine vascular compromise is a pathophysiologic hallmark of idiopathic sudden sensorineural hearing loss (ISSNHL). Some reports have discussed the relationship between OSA and hearing impairment; however, few have examined hearing prognosis in OSA and patients without OSA with ISSNHL. We aimed to investigate clinical manifestations of ISSNHL in patients with OSA, including severity of hearing loss and response to treatment. PATIENTS AND METHODS: A case-control study was conducted by extracting data from the sleep center and cochlea center databases of the Chang Gung Memorial Hospital. A retrospective chart review was performed to include confirmed adult OSA patients diagnosed with unilateral ISSNHL. Age and sex-matched patients without OSA with ISSNHL were enrolled as controls. Pure-tone average (PTA) thresholds were measured at specific frequencies. Changes in PTA before and after standard treatment with oral prednisolone (1mg/kg/day for 5 days, then tapered) and between participants with OSA and without OSA were compared. Standard treatment was given to all ISSNHL patients. RESULTS: Twenty-eight out of 8500 (0.33%) OSA patients experienced subsequent ISSNHL in 9 years. Patients with OSA (n=28) had poorer high-frequency perception in the unaffected ear than the patients without OSA (n=120), although the difference was not significant. Hearing in the affected ear among patients with OSA was comparable to that patients without OSA at individual frequencies and average, suggesting no difference in hearing loss in the affected ear between the two groups. In terms of high-frequencies (4000 and 8000 Hz) perception, patients with OSA had significantly poorer responses to steroid treatment than patients without OSA. CONCLUSION: ISSNHL may be one of the auditory complications associated with OSA. Patients with OSA had poorer prednisolone related hearing improvement in high frequencies than patients without OSA. Despite study limitations, OSA-related hypoxia and snoring noise is hazardous to hearing and standard treatments with CPAP is suggested in OSA patients for both holistic and auditory health.
RESUMEN
Hearing loss is a modifiable risk factor for dementia and cognitive decline. However, the association between cognition and hearing acuity at different frequencies is unknown. We aimed to assess the relationships between hearing acuity at different frequencies with global cognitive function and five domains of cognition among a low-income elderly population in northern rural China. A population-based cross-sectional study was conducted to collect basic information from elderly residents aged 60 years and older in rural areas of Tianjin, China from April 2012 to November 2013. Pure tone averages (PTAs) at different frequencies in the ear with better hearing and Mini-Mental State Examination (MMSE) scores were measured, and the relationships between these variables were assessed. A total of 737 residents aged 60 years or more were enrolled in this study, and the prevalence of hearing impairment was 60.7%. After adjusting for sex, age, education, income, smoking, drinking, systolic blood pressure (SBP), total cholesterol (TC), and low-density lipoprotein cholesterol level (LDL-C), MMSE score and immediate recall score were negatively associated with overall PTA (OPTA) at four frequencies (0.5, 1, 2, and 4 kHz), PTA at low frequencies (LPTA; 0.5, 1, and 2 kHz), and PTA at high frequencies (HPTA; 3, 4, and 8 kHz) in the ear with better hearing. Moreover, orientation score was negatively associated with OPTA and LPTA, and the attention and calculation scores were negatively associated with OPTA and HPTA. Each 10-dB increase in OPTA was associated with a MMSE score decrease of 0.464. Each 10-dB increase in LPTA or HPTA was associated with a MMSE score decrease of 0.441 (95% CI: -0.795, -0.086) and 0.351 (95% CI: -0.592, -0.110), respectively. The present study demonstrated significant but weak relationships between OPTA, LPTA, and HPTA with global cognitive function, as defined using MMSE scores; these relationships were independent of age, education, lifestyle factors, and laboratory test values. These results indicated that hearing was associated with cognitive decline among older individuals, who should be screened routinely to identify risk for cognitive decline.
RESUMEN
INTRODUCTION: The present study evaluates whether hearing deterioration during observation reduces serviceable hearing preservation rates after stereotactic radiosurgery (SRS) in vestibular schwannoma (VS) patients with useful hearing. METHODS: We retrospectively analyzed 1447 VS patients who underwent SRS between 1992 and 2017. We identified 100 VS patients who had Grade I Gardner- Robertson (GR) hearing at initial diagnosis but were observed without surgery or SRS. We compared hearing after SRS in 67 patients who retained GR Grade I hearing from initial diagnosis to SRS (the hearing maintenance or HM group) to 33 patients whose hearing worsened from GR grade I to grade II (the hearing deterioration or HD group). We also investigated whether a decline in pure tone average (PTA) or speech discrimination score (SDS) before SRS affected hearing preservation after SRS. RESULTS: The serviceable hearing (GR I and II) preservation in HM patients was 80%s, 63%, and 51% at 3, 5, and 10 years, respectively. The serviceable hearing preservation in HD patients was 40%, 33%, and 20% at 3, 5, and 10 years, respectively. In multivariate analysis, younger age (< 55 years, p = 0.045) and HM during observation (p = 0.001) improved serviceable hearing preservation rates. Patients whose PTA increased ≥ 15 dB (p = 0.024) or whose SDS declined ≥ 10% (p = 0.019) had reduced serviceable hearing preservation rates. CONCLUSIONS: Hearing deterioration during observation before SRS reduced long term hearing preservation rate in VS patients with GR grade I hearing at initial diagnosis. SRS before hearing deterioration was recommended for hearing preservation.

The relation between degree of sensorineural hearing loss and maximum speech identification scores (PBmax) is commonly used in audiological diagnosis and rehabilitation. It is important to consider the relation between the degree of hearing loss and the lower boundary of PBmax, as the PBmax varies largely between subjects at a given degree of hearing loss. The present study determines the lower boundary by estimating the lower limit of the one-tailed 95% confidence limit (CL) for a Dantale I, word list, in a large group of young and older subjects with primarily sensorineural hearing loss. PBmax scores were measured using Dantale I, at 30 dB above the speech reception threshold or at the most comfortable level from 1,961 subjects with a wide range of pure-tone averages. A nonlinear quantile regression approach was applied to determine the lower boundary (95% CL) of PBmax scores. At a specific pure-tone average, if the measured PBmax is poorer than the lower boundary (95% CL) of PBmax, it may be considered disproportionately poor.

PURPOSE: To establish a standardized reporting system of cholesteatoma, the ChOLE classification has recently been introduced. We here aimed to systematically investigate the association between the ChOLE classification and (i) hearing, (ii) recidivism rate, and (iii) postoperative complications. These data may increase the utility of the ChOLE classification in clinical practice and research by stratifying patients according to expected outcomes or risks for complications. METHODS: In this prospective multicentric study, we included adult patients undergoing tympanomastoid surgery due to cholesteatoma. Main outcome measures included the association of the ChOLE classification system with (i) audiometric data including air conduction (AC) and bone conduction (BC) pure-tone average (PTA), and the air-bone gap (ABG), (ii) recidivism and complication. RESULTS: A total of 160 patients suffering from cholesteatoma were included. ChOLE stage distribution was stage I in 23 (14%), stage II in 128 (80%), and stage III in 9 (6%) patients. The ChOLE stage was associated with the postoperative AC PTA (p = 0.05) and the postoperative BC PTA (p = 0.02). Further, the status of the ossicular chain after surgery (ChOLE subdivision "O") was associated with both the postoperative ABG (p = 0.0001) and the postoperative AC PTA (p = 0.003). Moreover, we found an association between complications (ChOLE subdivision "L) and both the postoperative BC PTA (p = 0.04) and the postoperative ABG (p = 0.04). No association between the ChOLE stage was found to both cholesteatoma recidivism and surgical complications. CONCLUSION: The ChOLE classification is a new system to classify cholesteatomas. We provide evidence that hearing outcomes vary among different ChOLE stages. In particular, hearing outcomes are associated with the ChOLE subdivision "O" and "L". Thus, the ChOLE classification system has a predictive value regarding hearing outcomes.

Objective: To assess outcomes in autoimmune inner ear disease (AIED) after cochlear implantation (CI) through systematic review and meta-analysis. Databases Reviewed: PubMed, MedLine, Embase, and CINAHL. Methods: Databases were queried for inclusion of AIED patients who underwent CI with outcomes recorded ≥3 months postoperatively. We examined demographics, pure-tone average (PTA), speech perception, preoperative imaging, intraoperative management, and postoperative complications. Results: Twenty-six articles encompassing 124 patients met inclusion criteria. Mean implantation age was 26.2 years (range 4-65 years) with average length of follow-up at 28.2 months (range 3-120 months). Meta-analysis demonstrated significant improvement in speech perception following CI. There was a statistically significant improvement in speech recognition score (SRS) (standard mean difference [SMD] = 6.5, 95% confidence interval [CI], 4.8-8.0, P < 0.0001) as well as word recognition score (WRS) (SMD = 5.5, 95% CI, 4.2-6.8, P < 0.0001) after CI. Anomalous preoperative radiologic manifestations were reported by 57.7% (15/26) studies. Disease activity-related intraoperative adjustment was noted in 57.7% (15/26) studies; common consequences were cochlear drill-out (53.3%), difficult round window insertion (26.7%), and scala vestibuli insertion (26.7%). Frequent postoperative complications noted in 26.9% (7/26) studies included systemic AIED flares (71.4%) and wound healing delay (42.9%). Conclusion: Findings of this systematic review of AIED cochlear implant literature demonstrate a lack of consistent reporting standards for PTA and speech perception as well as a lack of long-term follow-up. Despite these findings, meta-analysis suggests that CI is a viable treatment for improving speech perception in AIED patients.
RESUMEN
INTRODUCTION: We aimed to retrospectively analyze the therapeutic outcomes of using glucocorticoid combined with a vasodilator, breviscapine, versus glucocorticoid alone in patients with sudden sensorineural hearing loss (SSNHL) and to explore the impact on different audiometric curves. METHODS: Data from 154 patients were collected between January 2017 and December 2018. Patients received treatments of either glucocorticoid combined with breviscapine (GC + Bre) or glucocorticoid alone (GC). These two groups were stratified into low frequencies SSNHL (LF-SSNHL), high frequencies SSNHL (HF-SSNHL), all frequencies SSNHL (AF-SSNHL), and total deafness SSNHL (TD-SSNHL) subgroups according to their corresponding audiograms. The hearing level was evaluated by pure tone audiometry, and hearing recovery was calculated by comparing the pure tone average (PTA) at pretreatment and 4 weeks after therapy. RESULTS: Hearing recovery was significantly greater for GC + Bre than GC-only treatment in the AF-SSNHL and TD-SSNHL subgroups (P < 0.05) and to a lesser extent in the LF-SSNHL and HF-SSNHL subgroups (P > 0.05). Logistic regression analysis also showed a favorable outcome for SSNHL in the GC + Bre group (odds ratio 2.848, P < 0.05). CONCLUSION: Treating SSNHL using glucocorticoid combined with breviscapine could be more beneficial than using glucocorticoid alone, especially for patients with AF-SSNHL and TD-SSNHL.
