Investigation and treatment of tinnitus.

This review explores the evidence and international guidelines in the assessment and treatment of tinnitus. Tinnitus is defined as the experience of sound without any external source and is usually a benign symptom but is in some cases caused by an underlying medical condition, which may require further work up and treatment. Tinnitus is often associated with psychological and social issues. Despite the lack of a cure for most tinnitus, there are multiple strategies available that can help reduce symptoms, including education, counseling, sound therapy and cognitive behavioural therapy.
