There are few reports of the treatment for severe hearing loss due to otitis media with antineutrophil cytoplasmic antibody-associated vasculitis (OMAAV) achieved by cochlear implantation (CI). Here, we have reported the case of a patient with severe bilateral sensorineural hearing loss with low-frequency residual hearing by OMAAV. CI was performed in her right ear based on the results of contrast-enhanced magnetic resonance imaging (CE-MRI) and promontory stimulation test (PST). The residual hearing in her right ear was preserved after CI and utilized for combined electric acoustic stimulation (EAS). The combined EAS was used for 3 years until the residual hearing became stabilized. However, the usable hearing in low frequency worsened gradually, and the fitting strategy of cochlear implant was changed from combined EAS to CI alone 4 years after CI. Even when the speech discrimination score with CI no longer exceeds 50 %, the patient continued using CI because of its advantages in maintaining the quality of life of the patient. The combined EAS was found to be a feasible option even in an OMAAV patient with residual hearing. CE-MRI and PST may thus be helpful in deciding the side of CI surgery in a patient with OMAAV.

The MYO7A gene is known to be responsible for both syndromic hearing loss (Usher syndrome type1B:USH1B) and non-syndromic hearing loss including autosomal dominant and autosomal recessive inheritance (DFNA11, DFNB2). However, the prevalence and detailed clinical features of MYO7A-associated hearing loss across a large population remain unclear. In this study, we conducted next-generation sequencing analysis for a large cohort of 10,042 Japanese hearing loss patients. As a result, 137 patients were identified with MYO7A-associated hearing loss so that the prevalence among Japanese hearing loss patients was 1.36%. We identified 70 disease-causing candidate variants in this study, with 36 of them being novel variants. All variants identified in autosomal dominant cases were missense or in-frame deletion variants. Among the autosomal recessive cases, all patients had at least one missense variant. On the other hand, in patients with Usher syndrome, almost half of the patients carried biallelic null variants (nonsense, splicing, and frameshift variants). Most of the autosomal dominant cases showed late-onset progressive hearing loss. On the other hand, cases with autosomal recessive inheritance or Usher syndrome showed congenital or early-onset hearing loss. The visual symptoms in the Usher syndrome cases developed between age 5–15, and the condition was diagnosed at about 6–15 years of age.

Background: Wideband tympanometry (WBT) has the potential to distinguish various mechanical middle ear and inner ear pathologies noninvasively. This study investigated the diagnostic value of WBT in the diagnosis of enlarged vestibular aqueduct (EVA). Methods: The absorbance and resonance frequency (RF) of patients with EVA (40 ears, 25 patients) and matched population controls (39 ears, 28 subjects) were compared, alongside receiver operating characteristic (ROC) analysis. Correlations between VA width and RF were also examined. Results: Patients with EVA had higher absorbance at low frequencies (226–917 Hz) and lower absorbance at high frequencies (2520–4896 Hz) compared to controls. The RF of the EVA group was significantly lower versus controls (751 [391–1165] vs. 933 [628–1346] Hz). The ROC analysis revealed area under the curve values of 0.771 and 0.801, respectively, for absorbance and RF. RF had a sensitivity, specificity, positive predictive value, and negative predictive value of 74.4%, 82.5%, 76.7%, and 80.6%, respectively, for diagnosing EVA. In the EVA group, the VA midpoint width (r = −0.334) and VA petrous width (r = −0.402) both significantly correlated with RF. Conclusions: Our findings support the utility of WBT for diagnosing EVA, with RF as the optimal index used.
