A Case of Eosinophilic Otitis Media Implanted with Bone-Anchored Hearing Aid Reviewed

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<sup>®</sup>) in her right ear. Average hearing threshold of 500, 1000 and 2000 was 35 dB using Baha<sup>®</sup>. Although audiometry revealed deterioration of the bone-conduction threshold in the right ear at five years after the Baha<sup>®</sup> implantation, she still had sufficient bone conduction hearing using Baha<sup>®</sup> because of the preserved bone-conduction in the contralateral ear. The Baha<sup>®</sup> hearing system is a clinically effective and good hearing rehabilitative device for patients with EOM.

We examined the data of 148 cases of tympanoplasty performed for adhesive otitis media from 1995 through 2018. The number of mild cases increased. We mainly performed mucous membrane transplantation as a preventive measure against adhesion from 1978 through 1994; after 2006, mainly cartilage tympanoplasty was performed. We compared the results between the two procedures. The ratio of cases with postoperative eardrum normalcy improved from 60% to 83%, and the success rate of hearing gain improved from 55% to 69% (former period vs. latter period). In the cases treated after 2006, we compared the hearing gain between the group that showed good pneumatization to a epitympanum or a mastoid cavity (84%) and the group which showed poor pneumatization only to a tympanic cavity on preoperative CT (46%); the former group showed a significantly high success rate of hearing gain (P=0.002). The mean age of the patients was 51.8 years old in the poor preoperative pneumatization group as compared to 31.1 years old in the group with good pneumatization in the preoperative CT. The patients in the good preoperative pneumatization group were significantly younger (P<0.001). The patients who showed good postoperative hearing were significantly younger (P<0.001). Young age and good pneumatization on the preoperative CT were shown to be predictors of good results of hearing, in case of considering the surgical indication and time. On the other hand, the hearing gain was poor in the patients with poor preoperative pneumatization who were of advanced age, even if planned staged tympanoplasty was performed. In such case, we should adopt the surgical procedure aimed at an ear canal or the eardrum form that was hard to cause otorrhea assuming the wearing of the hearing aid, otherwise examine the treatment policy that we took an option of the artificial hearing device into consideration.

Middle ear implants, which are granted a breakthrough device designation, are useful for patients with moderate-to-severe hearing loss, not only in those with inflammatory conditions unresponsive to conventional procedures but also in those with malformations such as congenital aural atresia. Sound waves can be transmitted directly into the inner ear in the form of vibration energy; therefore, it is possible to provide sound with lesser frequency distortion and higher clarity than a hearing aid. We investigated 19 patients with conductive or mixed hearing loss, who underwent middle ear implant (Vibrant Soundbridge) placement between 2012 and 2019. The mean difference between preoperative and unaided postoperative bone conduction thresholds was <5 dB at all frequencies (250–4000 Hz), 20 weeks postoperatively. Compared with unaided preoperative thresholds, the aided postoperative thresholds were significantly improved at all frequencies >250 Hz, 20 weeks postoperatively and at all frequencies >500 Hz even 5 years postoperatively. The word recognition score in the quiet condition was comparable to that observed with use of a hearing aid preoperatively. Postoperative complications included deterioration of bone conduction threshold (4 cases), infection that was controlled by antibiotics (2 cases), dysgeusia (1 case), and cable exposure in the ear canal, necessitating implant removal (1 case).
