The subjects of this study were 45 persons less than 19 years old who had undergone cochlear implant surgery at Ehime University hospital. In addition, a questionnaire survey was carried out of the mothers. Mothers of 25 of the subjects responded to the questionnaire. The questionnaire survey was intended to determine the operation to the idea and the indication for cochlear implant surgery for the contralateral ear. Also, in the case bilateral cochlear implants, data were collected about both the ear operations. The questionnaire contained items designed to determine the indication for the operation, the perceived advantages of cochlear implant surgery, the unfavorable aspects of the surgery, the future expectations for the child, the support needed by the child, and the indications for operation of the contralateral ear. Among the reasons for deciding on bilateral cochlear implant surgery was the hope of binaural hearing, and the point which wasn't good, it made add being anxious about bilateral cochlear implants. The results revealed that the reason why mothers chose cochlear implant surgery was the hope that the child can live and assimilate in the world of the spoken language. After operation, aural communication became possible. However, limitations of cochlear implant surgery were also revealed. Information compensation and high-quality social involvement were still problematic.
For this study, we analyzed the data of nine Alzheimer's disease (AD) patients who underwent a hearing aid fitting trial during their stay at the hospital. Five of them met the criteria for hearing aid fitting and evaluation, and succeeded in continuing to wear a hearing aid even after they left the hospital. The rest failed to meet the requirements and could not continue using a hearing aid after discharge from the hospital. There were no significant differences in the age, average hearing level, duration of hearing aid trial, ability to carry out activities of daily living (Barthel Index), dementia mental scale, duration of AD, awareness of hearing impairment, or results of the speech discrimination test between the two groups. However, significant differences in improvement of communication as evaluated by others and as assessed by self-evaluation by the clients themselves were found between the two groups, which suggested that these two factors might be useful as markers of the possible outcome of hearing aid fitting in AD patients.
We analyzed the data of 121 patients (121 ears) who were diagnosed as having Grade 3 or Grade 4 severe idiopathic sensorineural hearing loss. All patients were hospitalized between 2009 and 2013 at our hospital. Seventy patients had Grade 3 (60dB-89dB) hearing loss, while 51 had Grade 4 (≥90dB) hearing loss at the initial examination. The patients were divided into 3 groups according to the course of hearing improvement with treatment. The first group was the early improvement group, in which improvement of the hearing level by more than 20dB, with an average level of 5 frequencies, was observed within 7 days after the start of therapy. The second group was the later improvement group, in which improvement by more than 20dB was observed between 8 and 14 days after the start of therapy. The third group was the no improvement group, in which the improvement in hearing level did not exceed 20dB within 14 days after the start of treatment. The percentage of cured patients in the early improvement group was 68.0%, while that in the no improvement group was 8.2%, with a significant difference between the two groups.
An internet survey was conducted of company employees with hearing impairment aged 35 years or younger, with the objective of examining factors associated with work satisfaction in young people with hearing impairment. The hearing level was 100dB or more in 67% of the respondents, and the last school attended was a university or graduate school in the majority (60%). Of all the respondents, 74% were regular employees. Although 92% of the respondents understood the sign language, the auditory oral approach was primarily used for communication at the workplace. Information and communication support was mostly provided by means of printed materials and writing, and rarely using sign language. In regard to work satisfaction, 60% of the respondents indicated being “generally satisfied.” A factor analysis of the responses revealed that the work satisfaction consisted of three factors: a sense of belonging to the company, professional fulfillment, and supportive relationships. In addition, the age and hearing level were also identified as relevant factors. The survey revealed that the majority of young people with hearing impairment tended to have a high level of work satisfaction, despite insufficient information and communication support. The results suggest the need for establishment of long-term support to ensure job permanence for hearing-impaired employees, by focusing on their sense of belonging to the company and professional fulfillment.
