INTRODUCTION External auditory exostosis (EAE) is a benign, irreversible bony outgrowth that arises from the temporal bone. EAE projects into the external ear canal, potentially causing recurrent otitis externa and conductive hearing loss. AIM To determine lifetime prevalence of EAE in New Zealand (NZ) surfers. METHODS This study used an online national survey. RESULTS Respondents were 1376 NZ surfers (recreational = 868, competitive = 508). Mean surfing experience was 16.2 years. Most self-classified as advanced surfers (36.5%), followed by intermediate (30.2%), expert (20.1%) and beginner (13.2%). Surfers reported an average of 214.2 h surfing (28.6% during winter) for the previous year. Overall lifetime prevalence of EAE was 28.9% (32.1% male, 14.6% female; P < 0.001), with the highest proportion of EAE was observed bilaterally (21.3%). Competitive surfers reported a significantly (P < 0.001) higher lifetime prevalence of EAE than recreational surfers (45.3% vs. 19.2%). A significantly higher (P < 0.001) lifetime prevalence of EAE was identified as skill level increased (7.1% in beginners to 55.6% in experts) and a two-fold increase (P < 0.001) of EAE in the highest (vs. lowest) quartile of surfing exposure. Neither winter surfing exposure nor which Island surfed were associated with EAE prevalence. DISCUSSION Although not as prevalent as in previous NZ research using otologic examinations, this study indicated that almost one-third of NZ surfers reported having had a diagnosis of EAE. Regular general practitioner otologic assessment and advice on appropriate prevention strategies for patients who surf may help prevent large lesions, recurrent ear infections and progressive hearing loss.
引言 外耳道外生骨疣（EAE）是一种起源于颞骨的良性、不可逆的骨质增生。EAE突入外耳道，可能导致复发性外耳道炎和传导性听力损失。目的 确定新西兰冲浪者中外耳道外生骨疣的终生患病率。方法 本研究采用在线全国性调查。结果 受访者为1376名新西兰冲浪者（休闲冲浪者 = 868名，竞技冲浪者 = 508名）。平均冲浪经验为16.2年。大多数人将自己归类为高级冲浪者（36.5%），其次是中级冲浪者（30.2%）、专家级冲浪者（20.1%）和初学者（13.2%）。冲浪者报告前一年平均冲浪214.2小时（28.6%在冬季）。外耳道外生骨疣的总体终生患病率为28.9%（男性为32.1%，女性为14.6%；P < 0.001），双侧外耳道外生骨疣的比例最高（21.3%）。竞技冲浪者报告的外耳道外生骨疣终生患病率显著高于休闲冲浪者（P < 0.001）（45.3%对19.2%）。随着技能水平的提高，外耳道外生骨疣的终生患病率显著升高（P < 0.001）（初学者为7.1%，专家级为55.6%），冲浪暴露量最高四分位数（与最低四分位数相比）的外耳道外生骨疣患病率增加了两倍（P < 0.001）。冬季冲浪暴露和在哪个岛屿冲浪均与外耳道外生骨疣患病率无关。讨论 尽管本研究中该疾病的患病率不如新西兰先前使用耳科检查的研究中那么高，但本研究表明，近三分之一的新西兰冲浪者报告曾被诊断为外耳道外生骨疣。定期由全科医生进行耳科评估，并为冲浪患者提供适当的预防策略建议，可能有助于预防大的病变、复发性耳部感染和渐进性听力损失。
