Eighty-one children undergoing tonsillectomies and adenoidectomies (T and A) were compared with a control group of 88 hospital patients. A significantly higher incidence of prior T and A was found to have been performed on the siblings and parents of the T and A group than the controls. Environmental, genetic or attitudinal factors could be responsible for this familial clustering.
81名接受扁桃体切除和腺样体切除手术(T&A)的儿童与88名住院患者组成的对照组进行了比较。结果发现,T&A组儿童的兄弟姐妹和父母接受过T&A手术的发生率显著高于对照组。环境、遗传或态度因素可能是造成这种家族聚集现象的原因。
