Introduction: Auditory symptoms in individuals with Autistic Spectrum Disorder (ASD) are well described within the neurodevelopmental literature, yet there is minimal mention of ASD in Otolaryngology literature. This is surprising considering the potential clinical and diagnostic implications of this link, and the potential for ASD to present to Otolaryngologists in the form of unexplained auditory symptoms. The aims of this literature review were to explore the intersection of auditory symptoms and ASD from the perspective of clinical Otolaryngology, and to outline a clinically focused research agenda based on emerging themes relevant to Otolaryngology.
Methods: We searched Pubmed, Embase, Ovid and Cochrane library for studies until November 2021. Four authors independently reviewed 227 publications identified. 39 were filtered into the final analysis. The PRISMA 2020 guidelines were followed. The heterogeneity of literature meant that a Systematic Review was not feasible. Included studies were therefore classified thematically, forming the basis of the scoping review.
Results: Diagnostic theories for auditory symptoms in ASD include the entire auditory pathway and brain. There is a growing body of literature on auditory symptoms in ASD, suggesting that a primary diagnosis of ASD should be considered in patients presenting with otherwise unexplained auditory symptoms, and indicating a learning need for Otolaryngologists and audiologists, to whom these patients may present.
Conclusion: We recommend a research agenda focusing on multidisciplinary collaboration, stakeholder engagement, responsible clinical screening, and clarification of pathophysiological mechanisms and terminology.
