Repeated tympanometric screening of a regionally defined population of 3-year-old children defined a group of 42 children with middle ear disease which had persisted for at least 6 months. These children were treated by either myringotomy with adenoidectomy or myringotomy without adenoidectomy decided by random allocation. Postoperative observation during 6 months failed to disclose any difference in middle ear status between the two groups.
对一个地区界定的3岁儿童群体进行反复鼓室导抗图筛查,确定了42名患有中耳疾病且病程至少持续6个月的儿童。这些儿童通过随机分配,分别接受鼓膜切开术加腺样体切除术或单纯鼓膜切开术治疗。术后6个月的观察未发现两组中耳状况有任何差异。
