During a follow-up period varying from 6 months to 6 years, the authors followed 1685 transtympanal ventilating tubes (VT). The mean age of the patients was 4 years 11 months. The mean duration of the VT in the tympanic membrane is 14 months. In 10.4% of the cases otorrhea was noticed. The otorrhea forms a serious problem in 30% of the VT that show drainage; it is more frequent in younger children and in those with a history of recurrent otitis media, especially if they were associated with otorrhea. Perforations persisted in 1.3% of the ears.
在6个月至6年不等的随访期内，作者对1685根鼓膜置管（VT）进行了跟踪。患者的平均年龄为4岁11个月。鼓膜置管的平均时长为14个月。在10.4%的病例中发现有耳漏。在出现引流的鼓膜置管病例中，30%存在耳漏这一严重问题；在年幼儿童以及有复发性中耳炎病史的儿童中更常见，尤其是伴有耳漏的情况。1.3%的耳朵存在穿孔持续未愈的情况。
