Applications of Augmented Reality in Otolaryngology: A Systematic Review:

ObjectiveAugmented reality (AR) is a rapidly developing technology. The aim of this systematic review was to (1) identify and evaluate applications of AR in otolaryngology and (2) examine trends in publication over time.Data SourcesPubMed and EMBASE.Review MethodsA systematic review was performed according to PRISMA guidelines without temporal limits. Studies were included if they reported otolaryngology-related applications of AR. Exclusion criteria included non-English articles, abstracts, letters/commentaries, and reviews. A linear regression model was used to compare publication trends over time.ResultsTwenty-three articles representing 18 AR platforms were included. Publications increased between 1997 and 2018 (P < .05). Twelve studies were level 5 evidence; 9 studies, level 4; 1 study, level 2; and 1 study, level 1. There was no trend toward increased level of evidence over time. The most common subspecialties represented were rhinology (52.2%), head and neck (30.4%), and neurotology (26%). The most...
