【 摘 要 】

Introduction: Although 16% of the adult population have impaired hearing, only about 1% have a severe or profound impairment (pure-tone average over 0.5, 1, 2 and 4 kHz of 70 dB HL or worse in the better hearing ear). With the advent of cochlear implants attention has been focused on the minority with total impairments. Those with lesser impairments within this group have been studied infrequently, their characteristics seldom reported and their most appropriate management remains undetermined. The purpose of this thesis is to provide a clinically useful characterization of a hospital population of severely and profoundly impaired patients. Four principal aims were defined. Firstly to determine the aetiology of the impairment. Secondly to describe the major clinical and audiological features of the group. Thirdly to highlight practical testing and management difficulties. Fourthly to estimate aided disability and residual handicap.
