The purpose of this study was to assess the effects of rapid maxillary expansion on nasal airflow studies and mouth breathing habit. 15 children aged from 5 to 12 years underwent rapid palatal expansion for orthodontic abnormalities. Otolaryngologic evaluation, computerized active anterior rhinomanometric measurements and oral myo-functional disorder examination were obtained before treatment, 2 months after expansion and after a retention period of approximately 10/12 months. Based on this multidisciplinary judgment and confirmed by the rhinomanometric values two groups could be distinguished: a group of predominantly mouth breathers where the nasal airway resistance had an average decrease of 34% and a group of predominantly nasal breathers where the nasal airway resistance had an average decrease of less than 5%. From the initial 8 predominantly mouth breathers before treatment only 2 remained clinically unchanged. From these results it was concluded that for the 15 children involved in this study rapid maxillary expansion affected the nasal airway patency in a way tailored to the initial deficiency and had a significative effect on the respiratory mode.
本研究的目的是评估快速上颌扩弓对鼻气流研究和口呼吸习惯的影响。15名年龄在5至12岁的儿童因正畸异常接受了快速腭扩弓治疗。在治疗前、扩弓后2个月以及约10/12个月的保持期后，进行了耳鼻喉科评估、计算机化主动前鼻测压测量和口腔肌功能障碍检查。基于这种多学科判断并经鼻测压值证实，可区分出两组：一组主要为口呼吸者，其鼻气道阻力平均下降34%；另一组主要为鼻呼吸者，其鼻气道阻力平均下降不到5%。在治疗前最初的8名主要口呼吸者中，只有2名在临床上保持不变。从这些结果得出结论，对于参与本研究的15名儿童，快速上颌扩弓以一种与初始缺陷相适应的方式影响了鼻气道通畅性，并对呼吸模式有显著影响。
