A case is reported in which a Nucleus 22 channel cochlear implant was inserted into the basal turn of the cochlea of a patient with advanced otosclerosis. It then passed out of the anterior end of the basal turn into an otospongiotic cavity related to the cochlea. Seven electrodes were located in the basal turn and it was possible to map them sufficiently well for the patient to derive considerable benefit from the implant. The problem of implant induced facial nerve stimulation in otospongiosis is also discussed.
Within this study we have examined the particular hearing complaints of patients being considered for a cochlear implant and the specific benefits/shortcomings experienced by implanted patients using open-ended questionnaires. As we expected, the difficulty of hearing general conversation was the most common individual hearing complaint. However, 45% of complaints were concentrated in the 'psychosocial' category, which was significantly higher than that found among general audiological rehabilitation patients. The average number of benefits listed by patients having implants was significantly higher than that of the shortcomings. Moreover, the main benefits listed were focused on the acoustical and psychological factors, e.g. 'environmental sound awareness', 'general conversation easier' and 'feeling of self-confidence'. The main shortcomings were related to the acoustical and practical areas, e.g. hearing difficulty in noisy background, processor being cumbersome.
