Objective: To report a successful case of cochlear implantation and auditory training for the improvement of sound localization in a patient with single-sided deafness.
Study Design: Case report and literature review.
Setting: Tertiary referral otology practice.
Patient: Fifty-seven-year-old man receiving cochlear implantation after 8 years of unilateral sensorineural hearing loss.
Intervention: Initially, CROS hearing aid, then osseointegrated bone conduction system and finally cochlear implantation and auditory training.
Main Outcome Measures: Sound localization tests.
Result: Sound localization tests after CI and auditory training showed improvement when compared with testing performed after fitting of an osseointegrated bone conduction system.
Conclusion: Cochlear implantation followed by 3 months of auditory training may have improved sound localization in this patient with single-sided deafness. Further case-controlled studies need to be undertaken to ascertain whether CI alone without formal auditory training will promote the same results.
