Retrospective chart review.
A retrospective chart review from 1990 to 2007 at a university tertiary referral center.
Surfers from the west coast of the United States were twice as likely to have severe exostoses in the right ear compared with the left. Evaporative cooling from a predominant northerly wind direction during the coldest water temperature months in this region may contribute to this lateral bias because surfers on this coast spend most of their time facing west. Few postoperative complications were identified. No cases of facial nerve injury or entry into the temporomandibular joint occurred. Differences in preoperative versus postoperative pure-tone hearing thresholds were not significant.
Exostosis severity seems to correspond to the ear that is more exposed to the predominant coastal wind. We propose that evaporative cooling in a cold water environment contributes to greater progression of exostoses in the ear with more exposure to the predominant wind. Exostosis removal using the postauricular approach carries a low complication rate.
回顾性图表审查。
这是一项在大学三级转诊中心进行的 1990 年至 2007 年的回顾性图表审查。
与左耳相比，来自美国西海岸的冲浪者右耳发生严重外生骨疣的可能性是左耳的两倍。在该地区水温最低的寒冷月份，盛行北风引起的蒸发冷却可能导致这种侧偏，因为在该海岸冲浪的人大部分时间都面向西方。术后并发症很少。未发生面神经损伤或进入颞下颌关节的情况。术前与术后纯音听阈的差异无统计学意义。
外生骨疣的严重程度似乎与更暴露于主要沿海风的耳朵相对应。我们提出，在寒冷的水环境中，蒸发冷却会导致更多暴露于主要风的耳朵中外生骨疣的进展更快。采用耳后入路切除外生骨疣的并发症发生率较低。
