In patients with repeated exposure to cold water, such as cold water surfers and kayakers, the reactive exostoses can occur in the external auditory canal. The external auditory canal exostoses are multiple, benign bony growths. They can cause external auditory canal stenosis, leading to repeated otitis externa and potentially conductive hearing loss. It is vital to consider this entity in susceptible patients who report hearing loss, as timely intervention such as proper ear protection equipment can lower the risk of developing severe external auditory canal exostoses. We present a case of a 42-year-old male, cold water surfer with conductive hearing loss and bilateral external auditory canal (EAC) stenosis demonstrated on the computed tomography.
在反复接触冷水的患者中，如冷水冲浪者和皮划艇运动员，外耳道可出现反应性外生骨疣。外耳道外生骨疣是多发性良性骨质增生。它们可导致外耳道狭窄，进而引起反复的外耳道炎，并可能导致传导性听力损失。对于报告有听力损失的易感患者，考虑到这一情况至关重要，因为及时干预，如使用合适的耳部防护设备，可降低发生严重外耳道外生骨疣的风险。我们报告一例42岁男性冷水冲浪者的病例，其计算机断层扫描显示有传导性听力损失和双侧外耳道狭窄。
