Abstract

Background/Objectives. With a rapid palatal expander (RPE) is reported to be effective in increasing the volume of nasal cavities, with a restoration of physiological nasal airflow. The purpose of this retrospective clinical study was to evaluate, using Cone Beam Computed Tomography (CBCT), the volumetric changes and airflow velocity changes in the nasal cavities, retro-palatal and retro-glossal airways, resulting from the use of RPE with dental anchorage (group A), also comparing these data with patients non treated with RPE (group B). Methods. Sixteen subjects (aged 9.34 years) with transverse maxillary deficiency and unilateral posterior crossbite were treated with RPE with dental anchorage. Additionally, 8 patients (aged 11.11 years) with juvenile idiopathic arthritis, who did not undergo any orthodontic treatment, were selected as a control group. Expansion was performed until overcorrection was achieved, and the device was left in place for 6 months as fixed retention, followed by another 6 months of night-time removable retention. From the retrospective evaluation, all patients presented two CBCT scans at baseline (T0) and 1-year follow-up (T1). The 3D-Slicer software was used for each CBCT to measure the nasal (VN), retropalatal (VRP), and retroglossal (VRG) volumes, while an iterative Excel spreadsheet allowed for a pilot approximated modeling and calculation of airway flow-related data. Results. Regarding mean age, a statistically significant difference (p = 0.01 *) was found between groups, suggesting that group B is closer to the pubertal growth peak. Analysis between T0 and T1 revealed: (i) a statistically significant increase for volumes VN, VRP and VRG in group A; (ii) a statistically significant increase for VN in group B; (iii) a statistically significant decrease for all variables related to airflow velocity in both groups. Furthermore, comparison between group A and B, regarding variations between T0 and T1, found a statistically significant difference only for VN. Conclusions. Within the limitations of this pilot evaluation, the treatment with RPE revealed promising outcomes for retro-palatal, retro-glossal and nasal volumes, together with clinical changes in airflow velocities.

快速腭扩张器(RPE)治疗患者气道空间和流量的变化:一项与未治疗患者比较的观察性初步研究。
背景/目标。据报道,快速腭扩张器(RPE)可以有效地增加鼻腔体积,恢复生理鼻腔气流。本回顾性临床研究的目的是利用锥形束ct (Cone Beam Computed Tomography, CBCT)评估使用RPE联合牙支具(A组)后鼻腔、腭后和舌后气道的体积变化和气流速度变化,并将这些数据与未使用RPE的患者(B组)进行比较。方法。对16例上颌横向缺损伴单侧后牙合的患者(年龄9.34岁)进行牙支抗RPE治疗。另外,选取未接受任何正畸治疗的8例青少年特发性关节炎患者(年龄11.11岁)作为对照组。进行扩展直到矫直过度,然后将该装置固定固定6个月,然后再进行6个月的夜间可拆卸固定。从回顾性评估来看,所有患者在基线(T0)和1年随访(T1)时均进行了两次CBCT扫描。每个CBCT使用3d切片软件来测量鼻(VN)、腭后(VRP)和舌后(VRG)体积,而迭代Excel电子表格允许试点近似建模和气道血流相关数据的计算。结果。组间平均年龄差异有统计学意义(p = 0.01 *),说明B组更接近青春期生长高峰。T0与T1间的分析显示:(i) a组VN、VRP、VRG体积增加,具有统计学意义;(ii) B组VN有统计学意义的增加;(iii)两组中与气流速度相关的所有变量均有统计学上的显著下降。此外,比较A组和B组T0和T1的变化,发现只有VN有统计学差异。结论。在这项试点评估的局限性内,RPE治疗在腭后、舌后和鼻体积以及气流速度的临床变化方面显示出良好的结果。
