the aim of this study was to evaluate cephalometrically the upper respiratory airway dimensions before and after rapid maxillary expansion.
rapid palatal expansion was performed on 24 5-9 year old children with adenotonsillar hypertrophy determined radiographically by means of lateral cephalographs. Also, the subjects were questioned concerning their ability to breath through their noses.
there was an increase in upper respiratory width that often coincided with a reported improvement in nasal respiration. Adenoid volume was not reduced.
the increase in pharyngeal space and improvement in nasal breathing resulted from an increase in pharyngeal lumen enlargement rather than a reduction in the volume of the adenoid tissue.
本研究旨在通过头影测量法评估快速上颌扩弓前后上呼吸道的尺寸。
对24名5至9岁经X线侧位头影测量片确定患有腺样体扁桃体肥大的儿童进行快速腭扩弓。此外，还询问了受试者经鼻呼吸的能力。
上呼吸道宽度增加，这通常与报告的鼻呼吸改善情况相符。腺样体体积未减小。
咽腔空间的增加和鼻呼吸的改善是由于咽腔扩大，而非腺样体组织体积减小所致。
