The objective of this study was to evaluate volumetric changes in the upper airway using Cone Beam Computed Tomography (CBCT) in orthodontic patients with maxillary transversal hypoplasia undergoing maxillary disjunction. The influence of factors such as sex, age, and growth pattern on airway volumetric changes was also assessed. The sample consisted of 50 growing patients from the dental clinic of Cardenal Herrera CEU University of Valencia. Airway volume was measured in mm3 before treatment (T0) and after palatal disjunction (T1). The final sample included 37 subjects in the treatment group and 13 in the control group. The volume gained exclusively from the disjunction treatment was determined to differentiate it from natural growth. The control group showed a mean volume increase from 10,911.3 ± 1,249.6 mm3 to 13,168.9 ± 1,789.7 mm3, representing a mean increase of 2,257.6 mm3 or + 20.9%. The treatment group exhibited an increase from 14,126.3 ± 4,399.8 mm3 at T0 to 18,064.1 ± 4,565.9 mm3 at T1, corresponding to a gain of 3,937.8 mm3 or + 31.8%. Significant differences in airway volume were observed after palatal disjunction compared to the control group. The expansion of the maxilla led to a significant increase in airway volume in the treated patients, estimated at 5,183 mm3 (+ 41.5%).
本研究旨在通过锥形束 CT（CBCT）评估上颌横向发育不足的正畸患者行上颌骨离断术后上气道的容积变化，并评估性别、年龄和生长模式等因素对上气道容积变化的影响。该研究样本包括来自瓦伦西亚 Cardenal Herrera CEU 大学牙科诊所的 50 名生长发育期患者。在治疗前（T0）和行腭离断术后（T1）分别测量气道容积（以 mm3 为单位）。最终治疗组纳入 37 例患者，对照组纳入 13 例患者。为了区分单纯因离断治疗而获得的气道容积变化与自然生长，确定了仅因离断治疗而获得的容积。对照组的气道容积从 T0 的 10911.3±1249.6 mm3 增加到 T1 的 13168.9±1789.7 mm3，平均增加 2257.6 mm3，增加了 20.9%。治疗组的气道容积从 T0 的 14126.3±4399.8 mm3 增加到 T1 的 18064.1±4565.9 mm3，增加了 3937.8 mm3，增加了 31.8%。与对照组相比，腭离断术后气道容积差异有统计学意义。上颌骨的扩张导致治疗组患者的气道容积显著增加，估计为 5183 mm3（增加了 41.5%）。
