OBJECTIVES: Listening effort is the mental effort that increases in situations where listening is challenging. Objective indicators are needed to assess listening effort, but no established testing methods can be performed in a daily environment. We used a glasses-type wearable device (JINS MEME, JINS Inc., Tokyo, Japan) equipped with an electrooculography sensor and an acceleration/angular velocity sensor to measure the number of eye blinks and changes in head tilt angle during listening under noise and investigated its use as an objective indicator of listening effort. DESIGN: The study included 16 normal-hearing individuals (mean = 27.94 years, SD = 7.18 years). They wore a glasses-type wearable device and were asked to repeat a passage presented at a sound pressure level of 60 dB sound pressure level. Three conditions were performed with signal to noise ratios (SNRs) of 0, -5, and -10 dB SNR. The number of eye blinks and head tilt angle were measured during the time spent listening to the conversation (listening period) and the time spent repeating it after listening (response period). After each task, the effort and motivation required for that trial were evaluated subjectively on a scale. Friedman tests were performed on the percentage of correct words repeated as well as subjective scores for effort and motivation based on the SNR. A linear mixed model was used to evaluate the effects of SNR and interval (listening period and response period) on the number of eye blinks and head tilt angle. In addition, correlation analysis was performed on each indicator. RESULTS: As the SNR decreased, the correct answer rate and motivation score decreased, and the effort score increased. These changes were significantly greater at -10 dB SNR than in the other 2 conditions. The eye blink rate was significantly higher in the -5 dB SNR condition than at 0 dB SNR, and was significantly higher in the response period than in the listening period, regardless of SNR. The head tilt angle was tilted forward when the SNR decreased in the listening period and response period sections. No significant correlation was observed between the indicators. CONCLUSIONS: The number of eye blinks increased during listening in noise, but decreased with decreased subjective motivation. The head tilt angle tilted forward when the noise load increased, indicating that the participant tilted more toward the sound source. The changes in the number of eye blinks and head tilt angle during listening in noise may be objective indicators related to listening effort that can be detected quantitatively and simply using a glasses-type wearable device.

OBJECTIVES: Although several studies have reported the benefits of intratympanic steroid injection (ISI) in the treatment of idiopathic sudden sensorineural hearing loss (SSHL), its effectiveness remains controversial. The purpose of this study was to evaluate the efficacy of ISI as a salvage therapy for SSHL and identify factors associated with treatment outcomes. METHODS: We retrospectively reviewed the medical records of 119 patients who received systemic steroids for the treatment of SSHL at our hospital between 2014 and 2023. Of the 76 patients who were not complete recovery after systemic administration, 56 were treated using ISI as a salvage therapy. RESULTS: Among the 76 patients who were not complete recovery after systemic administration, a short period between onset and systemic steroid administration (<4 days) showed favorable treatment effects (p = 0.020). We focused on the 56 patients treated using salvage ISI therapy to evaluate the prognostic factors affecting the efficacy of ISI therapy. The mean hearing loss values were 84.1 dB at the initial visit, 70.7 dB on completion of systemic steroid administration, and 61.8 dB at the final evaluation after ISI. In the univariate analysis, patients who received ISI <23 days after SSHL onset, those who had a hearing loss of ≥60 dB at the initial visit, and those who presented with vertigo at the initial presentation had better hearing recovery with ISI than those who did not (p < 0.01, p = 0.021, and p = 0.052, respectively). Multivariate analysis revealed that a period of <23 days from onset to salvage therapy was independently associated with favorable ISI effects (p = 0.032). CONCLUSIONS: In patients with SSHL, the introduction of salvage ISI therapy <23 days after onset contributes to good hearing recovery. In addition, salvage ISI therapy might be an optional treatment for patients whose hearing loss is ≥60 dB at the initial visit or who present with vertigo at the initial examination.

OBJECTIVE: The hearing aid adoption rate among older adults in Japan is lower than that in other developed countries. Herein, a survey was conducted to identify this bottleneck and develop countermeasures. This study aimed to examine whether raising awareness of the relationship between hearing loss and dementia is significant for hearing tests and adopting hearing aids. METHODS: A questionnaire was administered to participants aged 65 or older who visited a general hospital to determine the background factors (1) for a recent history of hearing tests, (2) for the desire to visit an otolaryngologist and have a hearing test, (3) for recognizing the hearing loss-dementia relationship, and (4) for adopting hearing aids. RESULTS: A total of 517 patients (mean age, 78.06; SD 6.97), representing 2.4% of the region's older-adult population, participated in the survey. A history of hearing tests within five years was significantly associated with recognizing the hearing loss-dementia relationship (adjusted OR 2.36, 95% CI 1.49-3.72). The desire to visit an otolaryngologist or have a hearing test was significantly associated with recognizing the hearing loss-dementia relationship (adjusted OR 1.70, 95% CI 1.02-2.85). Moreover, 39.3% were aware of the hearing loss-dementia relationship. The significant associated factors were being female (OR 2.50, 95% CI 1.64-3.81) and having interpersonal hobbies (OR 1.66, 95% CI 1.11-2.49). The significant background factors for adopting hearing aids were older age (OR 6.95, 95% CI 1.90-25.40), self-reported severe hearing impairment (OR 5.49, 95% CI 2.55-11.80), and living alone (OR 2.63, 95% CI 1.18-5.89). Recognizing the hearing loss-dementia relationship was not a significant factor. CONCLUSION: Raising awareness of the hearing loss-dementia relationship was not associated with adopting hearing aids for self-reported hearing impairments. However, it may be associated with otolaryngology visits and hearing tests. Thus, steps like hearing screening for older adults are also essential.

Middle-Ear Salivary Gland Choristoma with Congenital, Single-Sided Hearing Loss. 査読

記述言語：英語掲載種別：研究論文（学術雑誌）

Middle-ear salivary gland choristoma (SGCh) is a rare, benign tumor that causes conductive hearing loss owing to middle-ear morphological abnormalities. Early diagnosis is challenging, and surgical resection is indispensable for a definitive diagnosis. We report the case of a 3-year-old boy diagnosed with middle-ear SGCh during the follow-up period for left-sided hearing loss discovered at newborn hearing screening (NHS). Long-term follow-up after the NHS result, subsequent computed tomography/magnetic resonance imaging, and surgical resection led to its relatively early diagnosis and treatment.

Choosing the optimal side for cochlear implantation (CI) remains a major challenge because of the lack of evidence. We investigated the choice of the surgery side for CI (i.e., the better- or poorer-hearing ear) in patients with asymmetric hearing. Audiological records of 74 adults with a unilateral hearing aid who had undergone surgery at Okayama University Hospital were reviewed. The definition of 'better-hearing ear' was the aided ear, and the unaided ear was considered the poorer-hearing ear. We performed a multiple regression analysis to identify potential predictors of speech recognition performance after unilateral CI in the patients. Fifty-two patients underwent CI in the poorer-hearing ear. The post-Ci bimodal hearing rate was far higher in the poorer-ear group (77.8% vs. 22.2%). A multivariate analysis revealed that prelingual hearing loss and the patient's age at CI significantly affected the speech recognition outcome (beta coefficients: 24.6 and -0.33, 95% confidence intervals [11.75-37.45] and [-0.58 to -0.09], respectively), but the CI surgery side did not (-6.76, [-14.92-1.39]). Unilateral CI in the poorer-hearing ear may therefore be a reasonable choice for adult patients with postlingual severe hearing loss, providing a greater opportunity for postoperative bimodal hearing.
