Abstract

<p>　　We retrospectively examined the validity of our criteria for bilateral cochlear implantation in adults at our Hospital. The subjects were 11 patients who had undergone bilateral cochlear implantation and speech perception tests at least twice, before and at 3, 6, or 12 months after the operation. In this study, improvement in speech perception using the loudspeaker method, subjective evaluation and social participation were evaluated. The results were satisfactory in 10 of the 11 patients, suggesting that our criteria are generally appropriate. The remaining one patient was 70 years old and had lost hearing in the worse ear for about 28 years. Of the patients in their 70s who underwent cochlear implantation and showed good results of speech perception, the most prolonged period of hearing loss was 10 years. Therefore, we propose to add a new criterion for cochlear implantation in adults as a supplementary item and conduct further investigation: “Careful consideration should be given to those over 70 years of age with an over 10-year history of hearing loss.”</p>
