Fifty-four surfers and 38 surf life savers were examined and questioned in order to determine the prevalence of exostoses. Seventy-three per cent had evidence of body exostoses in the external auditory meatus. Forty per cent had their ear canals narrowed by 50% or more. The relationship between the number of years spent surfing or life saving and the extent of canal stenosis was highly significant (P < 0.00001). Left and right ears were affected equally in this series and the obstruction appears to begin after approximately 7 years and is further aggravated by continued surfing. Over 90% of subjects who had participated for longer than 10 years had some evidence of exostoses. There was no significant association between the number of days per year or the number of hours per day spent surfing and the development of surfer's ear in this sample. Those who participated in their water sport over winter had significantly more exostoses than those who did not (P < 0.0001). Those who lived in the South Island (colder water) had more surfer's ear than those in the North Island (warmer water).
为了确定外生骨疣的患病率，对54名冲浪者和38名冲浪救生员进行了检查和询问。73%的人在外耳道有身体外生骨疣的迹象。40%的人耳道狭窄50%或更多。冲浪或从事救生工作的年限与耳道狭窄程度之间的关系非常显著（P < 0.00001）。在这个系列中，左右耳受影响程度相同，阻塞似乎在大约7年后开始，并且持续冲浪会使其进一步加重。超过90%参与超过10年的受试者有外生骨疣的一些迹象。在这个样本中，每年冲浪的天数或每天冲浪的小时数与冲浪者耳病的发生之间没有显著关联。在冬季参与水上运动的人比不参与的人有明显更多的外生骨疣（P < 0.0001）。生活在南岛（水温较低）的人比北岛（水温较高）的人有更多的冲浪者耳病。
