To reconcile conflicting reports concerning the incidence of otorrhea in children with tympanostomy tubes who swim without ear protection.
Articles were identified by MEDLINE search, Current Contents, and references from review articles, textbook chapters, and retrieved reports. Controlled trials of water precautions following tympanostomy tube placement were selected by independent observers and scored on 10 measures of study validity. Five English-language articles met all inclusion criteria.
Data were abstracted for an endpoint of otorrhea following swimming without ear protection with a minimum follow-up of 6 weeks.
Pooled analysis of 619 children revealed a rate difference of -5.04 (95% confidence interval [CI], -11.62 to 1.54). No significant difference in the incidence of otorrhea was noted between patients who swam without ear protection and nonswimmers.
There is no increase in incidence of otorrhea in children who swim without ear protection compared with children who do not swim following tympanostomy tube placement.
调和关于鼓膜置管儿童在未采取耳部保护措施的情况下游泳时耳漏发生率的相互矛盾的报告。
通过医学文献数据库（MEDLINE）检索、《现刊目次》以及综述文章、教科书章节和检索报告中的参考文献来识别文章。由独立观察员挑选鼓膜置管后采取防水措施的对照试验，并依据10项研究有效性指标进行评分。5篇英文文章符合所有纳入标准。
提取在未采取耳部保护措施的情况下游泳后耳漏这一终点的数据，最短随访时间为6周。
对619名儿童的汇总分析显示，率差为-5.04（95%置信区间[CI]，-11.62至1.54）。在未采取耳部保护措施游泳的患者与不游泳的患者之间，未观察到耳漏发生率有显著差异。
与鼓膜置管后不游泳的儿童相比，未采取耳部保护措施游泳的儿童耳漏发生率并未增加。
