Abstract

In this report, we present the results of our follow-up study of infants with hearing impairment who underwent consultation and subsequently received hearing aids at the Auditory and Cochlear Implant Center of Tokyo Medical University Hospital. The subjects were 24 infants who were diagnosed as having hearing loss at our center between January 2008 and June 2012. The average age at the first visit was 3.9 months. Newborn hearing screening was performed in 19 cases (79%). Detailed examinations of the distortion product otoacoustic emissions (DPOAE), auditory brainstem responses (ABR), and auditory steady state responses (ASSR) were used for the audiologic assessment. The average hearing levels were evaluated at the initial consultation and upon completion of the fitting process of the hearing aid. The period that elapsed between the initial use of the hearing aid and complete fitting of the hearing aid was recorded. The thresholds, gains and MOPs of the hearing aids were evaluated at the initial use and at completion of the fitting process. The average period that elapsed between the first use of the hearing aid and finalization of the fitting process was 6.5 months, and several problems occurred with the fitting of the hearing aids. The following issues were encountered in these patients: difficulty in evaluating the hearing levels (13 cases; 54%), ear mold (4 cases; 17%), howling noise (7 cases; 29%), fitting difficulties (20 cases; 83%), and difficulty in making the infant wear the hearing aid (9 cases; 38%). In the future, these issues should be addressed so that improvements can be made in these areas.
