Auditory exostosis in Australian warm water surfers: a cross-sectional study

Abstract Background Surfing is a popular sport in Australia, accounting for nearly 10% of the population. External auditory exostosis (EAE), also referred to as surfer’s ear, recognized potentially serious complication surfing. Cold water (water temperature below 19 °C) commonly cited risk factor, with prevalence EAE cold surfers ranging from 61 80%. However, there paucity studies reporting exposed temperatures above °C. With mean °C 28 °C, Gold Coast region Australia provides ideal environment assess main goal this study: and severity warm surfers. Methods Eligible participants were living surfing on (Queensland, Australia). Currently active over 18 years age, year-round, minimum five consecutive experience recruited participate. Included individuals asked complete questionnaire underwent bilateral otoscopy. Results A total 85 included, age 52.1 (standard deviation [SD] ±12.6 years) 35.5 (SD ±14.7 years). Nearly two-thirds (65.9%) had regular otological symptoms, most trapping (66%), hearing loss (48.2%), cerumen impaction (35.7%). Less than one-fifth (17.7%) reported use protective equipment EAE. The overall was 71.8%, having lesions (59%) mild grade (grade 1, 47.5%). There insufficient evidence any significant associations between outcomes (presence EAE) factors related experience, winter exposure, ability, equipment. Conclusion To best our knowledge, first study assessing waters (above °C). 71.8% highlights high condition population, regardless temperature. Future research should focus ways prevent
