The incidence of middle ear disease among black American children is lower than among white children. Many factors may contribute to this difference. The possibility of an anatomical variation regarding the cellularity of the mastoid process was investigated. The size of the mastoid air cell system was measured in black and white children with and without middle ear effusion. A significantly smaller mastoid air cell system was found in the groups with middle ear disease compared to those without disease. No difference between white and black children in diseased as well as non-diseased ears could be demonstrated.
美国黑人儿童中耳疾病的发病率低于白人儿童。许多因素可能导致这种差异。研究了关于乳突细胞构成的解剖变异的可能性。测量了有和没有中耳积液的黑人和白人儿童的乳突气房系统大小。与无中耳疾病的组相比，中耳疾病组的乳突气房系统明显更小。患病耳和未患病耳的白人儿童与黑人儿童之间未显示出差异。
