ABSTRACT

OBJECTIVE@#To explore the indications of cochlear implantation in postlingually deaf adults.@*METHOD@#Five postlingually deaf adults participated in our investigation, surgery age 19-58 (median age 26 years). All patients received 24R (Cochlear,Australia). Four weeks after operation, all the patients have started the program. Through one year follow-up, we used the categories of auditory performance (CAP) and speech intelligibility rating criteria (SIR) to assess their hearing ability and speech intelligibility.@*RESULT@#Through testing for five patients who used cochlear implant continuously more than one year by Pure-tone audiometry, CAP and SIR, we assessed and found that the five patients hearing threshold raise to 25-45 dB in 0.5 kHz, 1.0 kHz, 2.0 kHz, 4.0 kHz, CAP average of 3.4, SIR average of 2.4. Two patients' ability of speech recognition and emotional communication were not improved almost, while these ability in other three were improved in varying degrees.@*CONCLUSION@#For postlingual deaf adults caused by different reasons, how to make patients benefit from cochlear implantation and increase their capacity for independent living and self-confidence due to select surgical indications correctly.
