Unprotected water exposure as a cause of otorrhea in patients with tympanostomy tubes remains controversial. Although most otolaryngologists continue to recommend either the avoidance of swimming or the use of water precautions during swimming, evidence indicates that the infection rate may not be affected by this practice. This study prospectively evaluates the possible role of unprotected water exposure in the occurrence of post-tympanostomy-tube otorrhea.
Two hundred twelve consecutive patients undergoing tympanostomy tube placement were randomized into swimming and nonswimming groups. No special precautions (eg, ear plugs, canal occlusion, antibiotic drugs) were used in either group. This incidence of otorrhea was then compared between these groups.
One-year follow-up was obtained in 107 patients. There was no significant difference in the incidence of otorrhea or the number of otorrhea episodes between the two groups.
Swimming is not contraindicated in patients with tympanostomy tubes, and water precautions do not decrease the incidence of otorrhea.
鼓膜置管患者中，未受保护的耳部接触水作为耳漏的一个原因仍存在争议。尽管大多数耳鼻喉科医生继续建议避免游泳或在游泳时采取防水措施，但有证据表明这种做法可能不会影响感染率。本研究前瞻性评估了未受保护的耳部接触水在鼓膜置管后耳漏发生中的可能作用。
212例连续接受鼓膜置管的患者被随机分为游泳组和非游泳组。两组均未采取特殊预防措施（如耳塞、耳道堵塞、抗生素药物）。然后比较两组中耳漏的发生率。
107例患者获得了一年的随访。两组中耳漏的发生率或耳漏发作次数没有显著差异。
鼓膜置管患者游泳并非禁忌，防水措施也不会降低耳漏的发生率。
