The aim of this study was to assess the effect of RME on upper airway structure and its relationship to improvements in sleep disordered breathing.
The study was carried out in 23 children with malocclusion and OSA. Clinical assessment visits, daytime sleepiness questionnaire, polysomnography and orthognatodontic examination were performed before (T0) and 4 (T1) and 12 (T2) months after RME. CB CT scans with 2D and 3D reconstructions were performed before (T0) and 12 after months (T2) RME. The relationship between airway changes and improvements in sleep disordered breathing were evaluated.
In all cases, opening of the mid-palatal suture was successfully achieved. Volume of the total upper airways, nasal cavity, nasopharynx and oropharynx increased significantly as well as the nasal osseous width. The increase in posterior suture, pterygoid process, maxillary, nasal cross-sectional width were significantly correlated with total upper airway volume, nasal cavity volume, nasopharyngeal airway volume, and oropharyngeal airway volume. The improvement in AHI was correlated with the increase in total upper airway volume at 12 months.
The study provides important details about the effect of RME on upper airway structure, including an enlarged posterior suture, pterygoid process, maxillary width and nasal cross-sectional width and enlarged airway volume.
本研究旨在评估快速上颌扩弓（RME）对上气道结构的影响及其与睡眠呼吸障碍改善情况的关系。
对23名患有错牙合畸形和阻塞性睡眠呼吸暂停（OSA）的儿童进行了研究。在RME治疗前（T0）、治疗后4个月（T1）和12个月（T2）进行了临床评估、日间嗜睡问卷调查、多导睡眠图检查和正颌正畸检查。在RME治疗前（T0）和治疗后12个月（T2）进行了带有二维和三维重建的锥形束计算机断层扫描（CB CT）。评估了气道变化与睡眠呼吸障碍改善之间的关系。
在所有病例中，均成功实现了腭中缝的打开。总上气道、鼻腔、鼻咽和口咽的容积以及鼻骨宽度均显著增加。后缝、翼突、上颌骨、鼻横断面宽度的增加与总上气道容积、鼻腔容积、鼻咽气道容积和口咽气道容积显著相关。12个月时，呼吸暂停低通气指数（AHI）的改善与总上气道容积的增加相关。
该研究提供了关于RME对上气道结构影响的重要细节，包括后缝、翼突、上颌骨宽度和鼻横断面宽度增大以及气道容积增大。
