Tympanostomy tubes (TT) are frequently employed as treatment for otitis media (OM) although there is little-clinical or experimental evidence of their efficacy. Potential detriments of TT include cost, risk of inhalation anesthesia, intraoperative complications, and tympanic membrane (TM) damage. Potential benefits include elimination of the conductive hearing loss (CHL), reduction in the occurrence of acute purulent OM, and avoidance of sequelae. The cost/benefit ratio of TT has never been accurately determined and morbid complications of inhalation anesthesia and the surgical procedure appear to be rate. There is evidence that TT significantly reduce the CHL of OM as well as reduce the incidence of recurrent acute purulent OM and help avoid sequelae. It is therefore determined that the risk of TT insertion for middle ear effusion (occasional TM changes) can be justified, in properly selected patients, by the benefits (immediate improvement in hearing and reduction in the incidence of recurrent acute purulent OM).
鼓膜置管（TT）常被用于治疗中耳炎（OM），尽管几乎没有临床或实验证据证明其疗效。鼓膜置管的潜在危害包括成本、吸入麻醉风险、术中并发症以及鼓膜（TM）损伤。潜在益处包括消除传导性听力损失（CHL）、减少急性化脓性中耳炎的发生以及避免后遗症。鼓膜置管的成本效益比从未得到准确确定，吸入麻醉和手术操作的严重并发症似乎发生率较低。有证据表明，鼓膜置管能显著降低中耳炎的传导性听力损失，同时降低复发性急性化脓性中耳炎的发生率，并有助于避免后遗症。因此，对于中耳积液（偶尔有鼓膜变化）的患者，在适当选择的情况下，鼓膜置管的风险（偶尔的鼓膜变化）可通过其益处（听力立即改善以及复发性急性化脓性中耳炎发生率降低）来证明是合理的。
