    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.

    Bone conduction implants (BCIs) and middle ear implants (MEIs) are promising options for individuals with persistent chronic inflammation of the middle or outer ear. However, the structure of the middle ear is often altered in patients who undergo mastoidectomy or posterior wall removal for refractory otitis media, leaving uncertainty regarding the efficacy of hearing devices. Only a few studies have examined auditory outcomes based on the etiology of hearing impairment. We investigated hearing outcomes, including speech audiometry, in patients who underwent implantation after surgery for refractory otitis media. Our findings indicated that patients who received BCIs or MEIs achieved favorable hearing outcomes. Furthermore, a correlation was observed between the preoperative bone-conduction threshold at 1 kHz in the better ear and the sound-field threshold at 1 kHz with BCIs, whereas no correlation was observed between the preoperative bone-conduction threshold and the sound-field threshold with MEIs. This study highlights the positive impact of BCIs and MEIs in patients who undergo implantation after surgery for refractory otitis media. Additionally, our study identified parameters that predict postoperative efficacy.

    Eosinophilic otitis media (EOM) is characterized by the presence of highly viscous middle ear effusion containing eosinophils, and is usually associated with bronchial asthma. Intratympanic corticosteroid administration and/or systemic steroid administration are effective treatments. However, the middle ear effusion and progressive hearing loss are difficult to control, significantly affecting the patient’s quality of life. Therefore, appropriate care is important not only for controlling the middle ear effusion and otorrhea, but also for preventing the progression of hearing loss. A 46-year-old woman was referred to our hospital with suspected eosinophilic otitis media. She had a history of asthma and aspirin sensitivity. In addition, she had recurrent nasal polyps despite having undergone nasal polypectomy on two occasions. She was diagnosed as having bilateral EOM according to the diagnostic criteria. She was started on steroid treatment, but after showing initial response, the middle ear effusion recurred immediately after withdrawal of steroid treatment. Although the patient also had difficulty in communication because of bilateral hearing loss, she could not wear hearing aids because of the middle ear effusion. Hearing aids sometimes aggravate middle ear infection by blocking aeration, increasing the risk of sensorineural hearing loss. Therefore, we implanted a bone-anchored hearing aid (Baha®) in her right ear. Average hearing threshold of 500, 1000 and 2000 was 35 dB using Baha®. Although audiometry revealed deterioration of the bone-conduction threshold in the right ear at five years after the Baha® implantation, she still had sufficient bone conduction hearing using Baha® because of the preserved bone-conduction in the contralateral ear. The Baha® hearing system is a clinically effective and good hearing rehabilitative device for patients with EOM.

    Objective: An intact cochlear nerve is necessary for successful cochlear implantation (CI). Although the promontory stimulation test (PST) using a promontory stimulator (PS) and a transtympanic needle electrode is invasive, it is still commonly used to verify cochlear nerve function. PSs are currently unavailable because they are no longer manufactured; however, considering that PST continues to be beneficial in certain situations, alternative equipment is needed. The PNS-7000® (PNS) was developed as a neurologic instrument for stimulating the peripheral nerves. This study investigated the usefulness of the ear canal stimulation test (ECST) using PNS with a silver ball ear canal electrode, which is a new noninvasive alternative technique to the PST. Methods: ECST was performed from November 2013 to December 2018 using PS and PNS for patients with severe to profound sensorineural hearing loss. The electrical threshold, most comfortable loudness level, uncomfortable loudness level, dynamic range, and gap detection were measured in the ECST. The results of these measured PNS items were compared with PS. Results: ECST was performed in 61 ears of 35 patients (age, 59.9 ± 20.1 years) using PS and PNS. The sound sensation was elicited in 51 (83.6%) and 52 (85.2%) ears with PS and PNS, respectively. All items excluding GAP were measured in 46 (75%) and 43 (70%) ears at 50 and 100 Hz, respectively. GAP was measured in 33 ears by the ascending and descending methods using PS and PNS. Spearman's rank-order correlation coefficient revealed a significant positive linear correlation between the PS and PNS results in all measurements. No significant difference was found between the PS and PNS thresholds in all measured items. Conclusions: PNS is a useful instrument for performing ECST as a new alternative to PS. ECST using a silver ball electrode is a less invasive and easier test than PST.
