Each year in the UK over 30,000 patients undergo insertion of grommets. The grommet insertion may cause many problems like persistent otorrhoea, scarred drum, retraction pockets and retention. The grommets may be extruded from the middle ears by the normal epithelial migration mechanism once they have served their purpose. These may become infected and require removal. We have analysed the Department of Health Hospital Episode Statistics relating to the insertion and removal of grommets (ventilation tubes). We have shown that 7.6 per cent of patients who have grommets inserted will have grommets removed.
在英国，每年有超过30000名患者接受鼓膜通气管植入手术。鼓膜通气管植入可能会引发诸多问题，如持续性耳漏、鼓膜瘢痕形成、内陷袋和存留等。一旦鼓膜通气管完成其使命，它们可能会通过正常的上皮迁移机制从中耳挤出。这些挤出的通气管可能会感染，需要取出。我们分析了卫生部关于鼓膜通气管（通气管）植入和取出的医院病历统计数据。我们发现，植入鼓膜通气管的患者中有7.6%将会取出通气管。
