What Works for Tinnitus and What’s New?
Tinnitus is the perception of sound in the absence of an external sound source. In the mid-20th century, Edmund Prince Fowler Snr (1872–1966) an American Otologist, developed a comprehensive clinical protocol for tinnitus practice. In the first half of this review, Fowler's practice will be compared to the clinical practice guidelines for tinnitus recently released by the American Academy of Otolaryngology, with a focus on “what works”. In the second half “what’s new” new innovative assessments (electrophysiological and blood biomarkers), personalised sound treatments, non-invasive brain stimulation and possible therapeutics (e.g. 3,4-Methylenedioxymethamphetamine) will be described with a particular focus on the work being undertaken in NZ. Fowler's progressive approach to tinnitus and focus on the individual will then be considered in light of recent developments in tinnitus.
