1Department of Epidemiology and Public Health, Foch Hospital, Suresnes, France. al.vallee@hopital-foch.com.
Summary
Surfer's ear (external auditory exostosis) affects over 67% of surfers due to cold water and wind exposure. Ear protection is crucial for preventing this condition.
Area of Science:
- Otolaryngology
- Environmental Health
Background:
- External auditory exostosis (EAE), or surfer's ear, is a common condition in surfers.
- It is characterized by bony growths in the ear canal due to cold water and wind exposure.
Approach:
- A systematic review of PubMed was conducted, analyzing original investigations on EAE prevalence in surfers.
- Data were collected from database inception to December 2022.
- Study quality was assessed using the AHRQ methodology checklist.
Key Points:
- 19 articles comprising 2997 surfers were analyzed.
- EAE prevalence ranged from 53% to 90%, with a mean of 67.8%.
- Studies were conducted across the USA, UK, Ireland, Australia, New Zealand, Japan, and Europe.
Conclusions:
- Prolonged surfing in cold, windy conditions significantly contributes to EAE development.
- Symptoms vary from mild discomfort to hearing loss and infections.
- Awareness and ear protection are vital preventive measures; further research is needed.
