There have been suggestions that maxillary expansion may be justified on the basis of airway considerations alone. The present study assessed the effects of rapid maxillary expansion and surgical expansion on nasal airway size to determine how useful these techniques are for breathing purposes. The results demonstrate that both procedures generally improve the nasal airway. However, approximately one third of the subjects in both groups did not achieve enough improvement to eliminate the probability of obligatory mouth breathing. These findings suggest that maxillary expansion for airway purposes alone is not justified.
有人提出仅基于气道考虑上颌扩弓可能是合理的。本研究评估了快速上颌扩弓和外科扩弓对鼻气道大小的影响，以确定这些技术对呼吸目的的有用程度。结果表明，两种方法通常都能改善鼻气道。然而，两组中约三分之一的受试者没有获得足够的改善以消除必须经口呼吸的可能性。这些发现表明，仅为气道目的进行上颌扩弓是不合理的。
