To examine how individual surfing behaviour affects the development of external auditory canal exostosis and to produce a model to predict exostosis severity. A standardised questionnaire was completed and each participant underwent an otoscopic examination. Surfers were recruited from August to October 2011 from surfing competitions and from colleges in the South West of England. 207 surfers were included, 53 % had evidence of external auditory canal; exostosis: grade 1, 23%; grade 2, 16%, grade 3, 16%. This risk of exostosis significantly increased with (1) surfing for 6 or more years, (2) surfing in the winter months, (3) surfing five or more times per month in the winter and (4) reported ear symptoms. Interestingly, participation in other water sports and wearing earplugs or a hood reduced the risk of developing exostosis. Surfers who surf in England are at significant risk of exostosis. A probability model was designed, incorporating different surfing behaviours and ear symptoms, the first of its kind in exostosis research. This model will be a useful tool for raising awareness of external ear canal exostosis in the surfing community and in assessing individual need for surgical intervention.
研究个体冲浪行为如何影响外耳道外生骨疣的发展，并建立一个预测外生骨疣严重程度的模型。完成了一份标准化问卷，每位参与者都接受了耳镜检查。2011年8月至10月期间，从冲浪比赛和英格兰西南部的学院招募冲浪者。共纳入207名冲浪者，53%有外耳道外生骨疣证据：1级占23%；2级占16%，3级占16%。外生骨疣的风险随着以下因素显著增加：（1）冲浪6年或更长时间；（2）在冬季冲浪；（3）冬季每月冲浪5次或更多次；（4）有耳部症状。有趣的是，参与其他水上运动以及佩戴耳塞或头罩可降低发生外生骨疣的风险。在英国冲浪的人有患外生骨疣的显著风险。设计了一个概率模型，纳入了不同的冲浪行为和耳部症状，这是外生骨疣研究中的首个此类模型。该模型将成为提高冲浪社区对外耳道外生骨疣认识以及评估个体手术干预需求的有用工具。
