External auditory exostosis (EAE) has previously only been shown to occur in cold water surfers. We assessed young surfers living and surfing in Queensland, Australia, for EAE in water temp ranges from 20.6 °C (69.1 °F, Winter) to 28.2 °C (82.8 °F, Summer). All participants underwent a bilateral otoscopic examination to assess the presence and severity of EAE. A total of 23 surfers participated with a mean age of 35.4 years (8.3 years) and a mean surfing experience of 20.0 years (9.9 years). Nearly two-thirds of participants (n = 14, 60.9%) had regular otological symptoms, most commonly water trapping (n = 13, 56.5%), pain (n = 8, 34.8%), and hearing loss (n = 6, 26.1%). Only 8.7% (n = 2) of all surfers reported regular use of protective equipment (e.g., earplugs) on a regular basis. The overall prevalence of exostosis was 69.6% (n = 16), and the majority (n = 12, 80.0%) demonstrated bilateral lesions of a mild grade (<33% obstruction of the external auditory canal). This is the first study assessing EAE in young surfers exposed to only warm waters (above 20.6 °C). The prevalence of EAE in this study highlights that EAE is not restricted to cold water conditions, as previously believed. Warm water surfing enthusiasts should be screened on a regular basis by their general medical practitioner and utilize prevention strategies such as earplugs to minimize exposure to EAE development.
外耳道外生骨疣（EAE）此前仅在冷水冲浪者中被发现。我们对生活在澳大利亚昆士兰州并在当地冲浪的年轻冲浪者进行了评估，这些冲浪者所处水温范围为20.6℃（69.1℉，冬季）至28.2℃（82.8℉，夏季）。所有参与者均接受了双侧耳镜检查，以评估EAE的存在情况及严重程度。共有23名冲浪者参与，平均年龄为35.4岁（±8.3岁），平均冲浪经验为20.0年（±9.9年）。近三分之二的参与者（n = 14，60.9%）有常见的耳科症状，最常见的是耳内积水（n = 13，56.5%）、疼痛（n = 8，34.8%）和听力损失（n = 6，26.1%）。在所有冲浪者中，只有8.7%（n = 2）的人报告经常定期使用防护装备（如耳塞）。外生骨疣的总体患病率为69.6%（n = 16），大多数（n = 12，80.0%）表现为双侧轻度病变（外耳道阻塞<33%）。这是第一项评估仅接触温水（高于20.6℃）的年轻冲浪者中EAE的研究。本研究中EAE的患病率表明，EAE并不像之前认为的那样仅限于冷水环境。温水冲浪爱好者应由其全科医生定期进行筛查，并采用如耳塞等预防策略，以尽量减少患EAE的风险。
