Perceived disability in children and adults with single sided deafness at two tertiary institutions
Background: Single-sided deafness is defined as a severe-to-profound hearing loss in one ear and normal or near-normal hearing in the other ear. The handicap experienced by patients with bilateral sensorineural hearing loss is well known, but the consequences of single-sided deafness are often …

Cochlear Implantation as a Treatment Option for Adults with Post-lingual Single Sided Deafness: A Systematic Review of the Literature
<p>Adults with post lingual single sided deafness experience a myriad of issues as a result of their condition. Speech perception in noise and localization are well documented as being compromised in this population due to the loss of binaural auditory input. Cochlear implantation was introduced in …
