The purpose of this study was to evaluate nasal airway resistance (NAR) during rapid maxillary expansion (RME) using acoustic rhinometry (AR). The sample comprised 22 children (13 girls and nine boys) with maxillary constriction. The mean age was 12.9 +/- 1.54 years and all patients were found to have normal nasal cavities following anterior rhinoscopic examination. A modified bonded splint type RME appliance was used for expansion. AR was used to measure NAR before (T1), during (T2) and after (T3) expansion, and at the end of retention (T4). Each AR recording was performed, for each patient, with and without the use of a decongestant. Subjective evaluation of reported changes in nasal breathing were also undertaken at T3. The results showed that NAR was significantly reduced with the use of RME, with the main decrease observed during expansion (P < 0.05). The use of a decongestant was not found to have any effect on the results. Subjective evaluation showed that 59 per cent of patients considered that their nasal breathing had improved following RME.
本研究的目的是使用鼻声反射（AR）评估快速上颌扩弓（RME）过程中的鼻气道阻力（NAR）。样本包括22名上颌缩窄的儿童（13名女孩和9名男孩）。平均年龄为12.9±1.54岁，所有患者在前鼻镜检查后均被发现鼻腔正常。使用改良的粘结夹板式RME矫治器进行扩弓。在扩弓前（T1）、扩弓期间（T2）、扩弓后（T3）以及保持期末（T4），使用AR测量NAR。对每位患者，在使用和不使用减充血剂的情况下进行每次AR记录。在T3时还对报告的鼻呼吸变化进行了主观评估。结果表明，使用RME后NAR显著降低，主要降低发生在扩弓期间（P<0.05）。未发现使用减充血剂对结果有任何影响。主观评估显示，59%的患者认为RME后鼻呼吸有所改善。
