The airway complex is modified by palatine expansion. Computer tomography has been used in the past to determine the change in volume, but there was a lack of a specific, reproducible method for this purpose. The present study sought to determine the accuracy, reproducibility, and repeatability of an innovative digital measurement technique for analyzing the volume of maxillary and nasal sinus airways following suture palatine expansion performed with the Hyrax disyuntor appliance.
Patients underwent preoperative and postoperative cone-beam computed tomography (CBCT) scans. The datasets were subsequently uploaded into a digital treatment planning software to record the volume of the right and left maxillary sinus, as well as the nasal and maxillary sinus airway complex. The Gage Repeatability & Reproducibility statistical analysis methodology was used to evaluate the repeatability and reproducibility of this measurement technique when measuring the volume of maxillary and nasal sinus airways following suture palatine expansion with the Hyrax disyuntor appliance. Additionally, comparative analysis between preoperative and postoperative measures was performed using Student's t-test for statistical analysis.
In 5 patients, paired t-tests found statistically significant differences before and after treatment in the volumes of the left maxillary sinus (p = 0.002), right maxillary sinus (p = 0.001), and nasal and maxillary sinus airway complex (p = 0.005) after suture palatine expansion with the Hyrax disyuntor appliance.
The proposed digital technique is an accurate, repeatable, and reproducible measurement technique for analyzing the volume of maxillary and nasal sinus airways following suture palatine expansion using the Hyrax disyuntor.
腭扩张会改变气道复合体。过去曾使用计算机断层扫描来确定体积变化，但缺乏用于此目的的特定、可重复的方法。本研究旨在确定使用 Hyrax 分离器进行腭缝合扩张后分析上颌窦和鼻气道复合体体积的创新数字测量技术的准确性、可重复性和可重复性。
患者接受术前和术后锥形束计算机断层扫描（CBCT）扫描。随后将数据集上传到数字治疗计划软件中，以记录右侧和左侧上颌窦以及鼻和上颌窦气道复合体的体积。使用 Gage 可重复性和再现性统计分析方法评估在使用 Hyrax 分离器进行腭缝合扩张后测量上颌窦和鼻气道复合体体积时该测量技术的可重复性和再现性。此外，使用学生 t 检验进行统计学分析，比较术前和术后测量值。
在 5 名患者中，配对 t 检验发现使用 Hyrax 分离器进行腭缝合扩张后，左上颌窦（p=0.002）、右上颌窦（p=0.001）和鼻上颌窦气道复合体的体积（p=0.005）在治疗前后存在统计学上的显著差异。
提出的数字技术是一种准确、可重复和可重现的测量技术，可用于分析使用 Hyrax 分离器进行腭缝合扩张后上颌窦和鼻气道复合体的体积。
