Characteristics of Patients with Hearing Aids according to the Degree and Pattern of Hearing Loss

Background and Objectives: This study was designed to assess the characteristics of patients according to the degree and audiogram shape of hearing loss and the association of these characteristics with hearing aids (HA) choice, return rate, and cause of return. Subjects and Methods: This study included 460 individuals who received HAs from 2011 to 2015. The relationships between type of HA and age, primary and accompanying symptoms, HA choice and return and cause of return were evaluated according to the degree and pattern of hearing loss. Results: HA type did not differ significantly according to the degree and pattern of hearing loss. Intensity of hearing loss was greater in male than in female (p< 0.05). Open and completely-in-canal types of HA decreased with age (p< 0.05). As degree of hearing loss intensified, behind-the-ear and in-the-ear types increased and Open type decreased (p< 0.05). The HA return rate was 9.7%, but was not associated with degree or pattern of hearing loss. The main causes of HA return were costs, psychological fears and adaptive failure. Conclusions: Choice of HA is affected by age, sex, and degree and pattern of hearing loss. HA for hearing rehabilitation in patients with hearing loss can be personalized according to each patient's characteristics and tendencies.
