The case study explores COVID-19 vaccination connection to tinnitus and hyperacusis, considering its onset and exacerbation post vaccination. The subject is a 47-year-old woman with a history of bilateral tinnitus, and her hearing history was tracked from 2014 to 2023. An intense episode of tinnitus occurred in 2021, distinct from previous experiences post COVID-19 vaccination, second dose. Symptoms manifested as sudden onset of hyperacusis, pronounced \"roar\" type tinnitus, and a sudden decline in hearing. Audiometric results showed reduce thresholds in low frequencies and lower speech scores in the left ear. This escalation significantly affects speech understanding in group conditions and noisy environments. There was a gradual improvement in tinnitus and hyperacusis severity, but the subject has a greater problem with speech understanding. The subject\'s journey involved visits to specialists, multiple testing including neuroimaging, naturopath consultations, and anxiety medication. It emphasizes the importance of healthcare practitioners recognizing and documenting these issues and need for timely multidisciplinary intervention and support. Further research is necessary to better understand the relationship between COVID-19, vaccination, and auditory symptoms.

As two line trends - aging disability and disability aging - continue to emerge, hearing disability is becoming increasingly prevalent among older adults in china. This study aimed to investigate the incidence of hearing disability among older adults and identify the various factors contributing to its development.
In this matched nested case-control study, data from the China Health and Retirement Longitudinal Study from 2011 to 2018 were analyzed. A total of 4,523 older adults were recruited from a national sample database, of which 1,094 individuals were eligible for inclusion in the hearing disability cohort, while 3,429 older adults who had not been diagnosed with hearing disability were considered non-hearing disability controls. Hearing disability was assessed by a self-reported question. These controls were matched to hearing disability cases in a 1:1 ratio based on age and sex. The logistic regression models were used to find out various factors of hearing disability in the target population.
Totally 1,094 individuals (24.14%) developed hearing disability during the follow-up period. After 1:1 matching, 2,182 subjects were included in the study, with 1,091 cases in the case group. Factors that influenced the incidence of hearing disability in older adults included annual per capita household income (OR = 0.985, p = 0.003), cognitive function (OR = 0.982, p = 0.015), depression level (OR = 1.027, p < 0.001), somatic mobility (OR = 0.946, p = 0.007), history of kidney disease (OR = 1.659, p < 0.001), history of asthma (OR = 1.527, p = 0.008), history of accidental injuries (OR = 1.348, p = 0.015), whether there is a place for recreational and fitness activities in the community (OR = 0.672, p < 0.001), and whether there is a health service center/health center in the community (OR = 0.882, p = 0.006).
The incidence of hearing disabilities among older adults in China is high. The protective and risk factors that contribute to the incidence of disability should be fully considered in the care of older adults.

OBJECTIVE: To investigate the hypothesis that day-case cochlear implantation is associated with equal quality of life, hearing benefits and complications rates, compared to inpatient cochlear implantation.
METHODS: A single-center, non-blinded, randomized controlled, equivalence trial in a tertiary referral center.
METHODS: Thirty adult patients with post-lingual bilateral sensorineural hearing loss eligible for unilateral cochlear implantation surgery were randomly assigned to either the day-case or inpatient treatment group. The effect on general quality of life, patient satisfaction, (subjective) hearing improvement, postoperative complications and causes of crossover and/or readmission were assessed using questionnaires, auditory evaluations and patients\' charts over a follow-up period of 1 year.
RESULTS: Overall quality of life measured by the HUI3 was equal between the day-case (n = 14) and inpatient group (n = 14). The overall patients\' satisfaction showed a slight favor towards an inpatient approach. There was no significant difference in the subjective and objective hearing improvement between both treatment groups. During the 1-year follow-up period no major complications occurred. Minor complications occurred intraoperatively in three day-case patients resulting in three out of nine admissions of day-case patients. Other causes of admission of day-case patients were nausea and vomiting (n = 1), drowsiness (n = 1), late scheduled surgery (n = 2), social reasons (n = 1), or due to an unclear reason (n = 1). No patients required readmission.
CONCLUSIONS: We found equal outcomes of QoL, patient satisfaction, objective, and subjective hearing outcomes between day-case and inpatient unilateral cochlear implantation. Nine out of 14 day-case patients were admitted for at least one night postoperatively (crossover). No major complications occurred in both groups. A day-case approach seems feasible when using specific patient selection, surgical planning and the preoperative provision of patient information into account. Besides this, the familiarity with a day-case approach of both patient and the surgical team can increase the feasibility of day-case surgery.
METHODS:

Cerebellopontine angle (CPA) meningiomas commonly involve the internal auditory canal (IAC). We report a case of a 68-year-old lady with idiopathic profound bilateral deafness with a meningioma which was discovered on workup for cochlear implantation. We performed simultaneous excision of her CPA and IAC meningioma with insertion of a cochlear implant (CI). She regained functional hearing with marked improvement in quality of life. Intraoperative electrophysiological testing can be used to confirm preservation of the cochlear nerve enabling simultaneous implantation which is preferable for clinical and logistical reasons. This creates an option for hearing rehabilitation at the time of IAC/CPA tumour surgery in appropriate patients.

OBJECTIVE: To describe the characteristics, management, and outcomes of pediatric patients with sporadic vestibular schwannoma (sVS).
METHODS: This was a case series at a tertiary care center. Patients were identified through a research repository and chart review. Interventions were microsurgery, stereotactic radiosurgery (SRS), and observation. Outcome measures were tumor control, facial nerve function, and hearing.
RESULTS: Eight patients over 2006-2022 fulfilled inclusion criteria (unilateral VS without genetic or clinical evidence of neurofibromatosis type 2 (NF2); age ≤ 21) with a mean age of 17 years (14-20). Average greatest tumor length in the internal auditory canal was 9.7 mm (4.0-16.1). Average greatest tumor dimension (4/8 tumors) in the cerebellopontine angle was 19.1 mm (11.3-26.8). Primary treatment was microsurgery in five (62.5%) patients, observation in two (25%), and SRS in one (12.5%). Four (80%) surgical patients had gross total resections, and one (20%) had regrowth post-near total resection and underwent SRS. One observed patient and the primary SRS patient have remained radiographically stable for 3.5 and 7 years, respectively. The other observed patient required surgery for tumor growth after 12 months of observation. Two surgical patients had poor facial nerve outcomes. All post-procedural patients developed anacusis. Mean follow-up was 3 years (0.5-7).
CONCLUSIONS: We describe one of the largest reported cohorts of pediatric sVS in the USA. Diligent exclusion of NF2 is critical. Given the high likelihood of eventually requiring intervention and known adverse effects of SRS, microsurgery remains the preferred treatment. However, observation can be considered in select situations.

Surgery for vestibular schwannoma can be divided into hearing-preserving and nonhearing-preserving surgeries. Hearing-preserving surgery is usually not considered in patients with deafness due to vestibular schwannoma, because hearing is unlikely to improve, and surgery aims to maximize the tumor resection at the expense of hearing. We report an extremely rare case of a 46-year-old man with unilateral profound hearing loss due to a vestibular schwannoma with marked cystic degeneration in the left cistern, which significantly recovered to near-normal hearing levels after hearing-preserving surgery. Hearing loss gradually worsened, and preoperative pure-tone evaluation showed complete hearing loss in the left ear. However, the response to the distortion product otoacoustic emission was preserved, and hearing loss was considered to be retrocochlear. Tumor resection was performed using the retrolabyrinthine approach with continuous monitoring using dorsal cochlear nucleus action potential, auditory brainstem response, and facial nerve function muscle action potential. The cistern portion of the tumor was almost completely resected along with the wall. Postoperatively, the pure-tone threshold on the left side markedly improved. The present case clearly demonstrates the possibility of hearing recovery in patients with retrocochlear hearing loss. We should consider expanding the indications for hearing-preserving surgery.

Bilateral vestibulopathy (BV) is a chronic vestibular disorder, characterized by bilaterally absent or significantly impaired vestibular function. Symptoms typically include, but are not limited to, unsteadiness and movement-induced blurred vision (oscillopsia). This prospective case-control study aimed to elucidate the impact of BV on cognitive and motor performance and on cognitive-motor interference. Cognitive and motor performance, as well as cognitive-motor interference were measured in persons with BV and normal hearing using the 2BALANCE dual-task protocol. The experimental group was matched to a healthy control group based on age, sex, and educational level. The 2BALANCE protocol comprises cognitive tests assessing visuospatial memory, mental rotation, visual and auditory response inhibition, visual and auditory working memory, and processing speed. The cognitive tests were performed in single-task condition (while seated), and in dual-task condition (during a static and a dynamic motor task). The static motor task consisted of balancing on a force platform with foam pad. The dynamic motor task consisted of walking at a self-selected speed. These motor tasks were also performed in single-task condition. A generalized estimating equations model was used to investigate group differences for all cognitive and motor outcome measures. The estimated marginal means, as well as the odds ratios (OR), and their 95% confidence intervals (CI) were calculated. For the backward digit recall test, a baseline measurement was performed and analyzed using a student-t test. A total of 22 patients with BV and normal hearing and 22 healthy control subjects were assessed [mean age (SD), BV = 53.66 (13.35) and HC = 53.21 (13.35), 68% male]. The BV group had poorer mental rotation skills in single-task condition, compared to the control group [odds ratio (OR) = 2.30, confidence interval (CI) = 1.12-4.73, P  =  0.024]. Similarly, auditory and visual working memory were also poorer in the BV group in single-task condition (P = 0.028 and P = 0.003, respectively). The BV group also performed poorer on the mental rotation task and the visual response inhibition task in dual-task condition (OR = 2.96, CI = 1.57-5.59, P  <  0.001 and OR = 1.08, CI = 1.01-1.16, P  =  0.032, respectively). Additionally, an interaction effect, indicating increased cognitive-motor interference in the BV group, was observed for mental rotation, response inhibition, and auditory working memory (P  =  0.003 to 0.028). All static motor outcome parameters indicated more postural sway in the BV group compared to the control group for all test conditions (P  <  0.001 to 0.026). No group differences were noted for the dynamic motor task. These findings suggest a link between vestibular function and cognitive performance, as well as a greater interference between cognitive and motor performance in BV, compared to healthy controls.

BACKGROUND: Cogan\'s syndrome is a rare form of vasculitis mainly affecting young subjects of whatever gender, associating cochleovestibular and ophthalmological damage. Despite medical treatment, auditory prognosis is uncertain, with 50-60% of patients showing irreversible severe to profound hearing loss, thus being candidates for cochlear implantation. Following CARE guidelines, we report 10 cases of cochlear implantation in Cogan\'s syndrome, with assessment of speech reception threshold and maximum intelligibility after a minimum 1 year\'s experience with the implant.
METHODS: Ten patients from 4 centers received cochlear implants (14 implants) for Cogan\'s syndrome between 2005 and 2020. After 1 year\'s experience, there was significant improvement in speech reception threshold (P=0.0002) and maximum intelligibility (P=0.0002).
CONCLUSIONS: Audiovestibular signs associated with ophthalmological manifestations should suggest Cogan\'s syndrome. Hearing impairment is usually irreversible. Cochlear implantation may be necessary and improves hearing performance.

BACKGROUND: There have been no papers reporting improvement in language function and changes in cerebral blood flow following repeated use of repetitive transcranial magnetic stimulation in combination with intensive speech-language-hearing therapy. This case report concerns the efficacy of repeated use of repetitive transcranial magnetic stimulation and intensive speech-language-hearing therapy for a certain patient suffering from aphasia following stroke, plus the findings of the cerebral blood flow measurements.
METHODS: The patient was a 71-year-old right-handed Japanese male who developed fluent aphasia following a left middle cerebral artery stroke. He underwent repetitive transcranial magnetic stimulation and intensive speech-language-hearing therapy five times in total. The repetitive transcranial magnetic stimulation was applied to right inferior frontal gyrus at the frequency of 1 Hz plus 2 hours per day of intensive speech-language-hearing therapy. The patient\'s language function was evaluated in the short term and long term. Cerebral blood flow was measured with single photon emission computed tomography scan. As a result, in the short term, the patient\'s language function improved especially during the initial hospitalization. In the long term, it improved gradually and stabilized.Cerebral blood flow was increased in the right hemisphere.
CONCLUSIONS: The findings of the study indicate that the repeated use of repetitive transcranial magnetic stimulation and intensive speech-language-hearing therapy may be effective in improving and preserving language function and increasing cerebral blood flow for aphasia following stroke.

In the new revised National Institute for Health & Care Excellence (NICE, TA566, 2019) guidelines for cochlear implantation (CI) have clearly stipulated that the hearing loss must be bilateral. Prior to this revision, children and young people (CYP) with asymmetrical thresholds have been considered for unilateral CI when one ear was in audiological criteria. Children with asymmetrical hearing loss represent an important cohort of potential CI candidates, who will continue to be prevented from benefiting from CI unless evidence is produced to support implantation and maximise subsequent benefit.The aim of this study is to evaluate the \'real-life\' hearing performance in a group of children who have received a unilateral CI and who have hearing thresholds in the contralateral ear that are outside the current UK NICE 2019 audiological criteria for CI. The contralateral ear will be aided using a conventional hearing aid (HA). The outcomes from this \'bimodal\' group will be compared with a group of children who have received bilateral CI, and a group of children using bilateral HA, to extend the current knowledge about the different performance levels between bilateral CI, bilateral HA and bimodal hearing in CYP.
Thirty CYP aged 6-17 years old, 10 bimodal users, 10 bilateral HA users and 10 bilateral cochlear implant users will be subjected to a test battery consisting of: (1) spatial release from masking, (2) complex pitch direction discrimination, (3) melodic identification, (4) perception of prosodic features in speech and (5) TEN test. Subjects will be tested in their optimal device modality. Standard demographic and hearing health information will be collected. In the absence of comparable published data to power the study, sample size was determined on pragmatic grounds. Tests are exploratory and for hypothesis generating purposes. Therefore, the standard criterion of p<0.05 will be used.
This has been approved by the Health Research Authority and NHS REC within the UK (22/EM/0104). Industry funding was secured via a competitive researcher-led grant application process. Trial results will be subject to publication according to the definition of the outcome presented in this protocol.
