关于乳突气化,文献中争论激烈的有Wittmaack(1918)提出后经Tumarkin(1959)等命名的环境学说和Dimant(1940)的遗传学说(又称“正常变异”学说)。前者认为健康的中耳粘膜是乳突正常气化的前提,婴幼儿中耳疾病和咽鼓管功能障碍是阻止气化的原因。后者根据正常成人乳突气房大小的变异呈常态分布,认为这种差异是由遗传决定的正常变异;气化不良容易患中耳炎,而中耳炎是乳突气化不良的结果。作者认为Wittmaack学说所依据的组织病理学研究已经陈旧,而Dimant的遗传学说是在
On mastoid gasification, there are heated arguments in the literature about the environmental doctrine proposed by Wittmaack (1918) after Tumenin (1959) and the genetic theory of Dimant (1940) (also known as “normal variation”). The former that the healthy middle ear mucosa is the premise of normal mastoid gasification, infantile middle ear disease and Eustachian tube dysfunction is to prevent gasification reasons. The latter is normally distributed according to the size of normal adult mastoid atrial size variation, which is considered to be a normal variant of inheritance; otitis media is susceptible to otitis media, and otitis media is the result of mastoid gasification. The author believes that the histopathological study on which the Wittmaack doctrine is based is outdated, whereas Dimant’s theory of genetics is outdated
