摘要

本研究的目的是评估使用微型辅助快速腭扩张器(MARPE)治疗上颌横向缺陷患者鼻咽气道体积的变化。本研究对20名接受MARPE矫治器治疗的患者进行了治疗前后的锥束计算机断层扫描。测量扩张前和扩张后鼻腔、鼻咽部和口咽部气道体积。采用鼻腔周围骨骼结构的线性测量来评估气道扩张的模式。配对t检验用于评价鼻咽气道体积随扩张的变化。采用Pearson相关检验评估鼻咽部容积变化的关系。20个样本中有17个成功地切开了中腭缝合线。扩张后鼻气道容积显著增加(12.0%)。此外,在鼻腔基底的正面宽度线性测量值显著增加(7.1%),在横向尺寸的前后宽度均显著增加(分别为9.4%和3.4%)。上颌扩张器宽度增加与气道容积呈正相关。使用MARPE矫治器进行上颌扩张的效果包括鼻腔体积的增加,但不包括鼻咽和口咽气道体积的增加。使用MARPE矫形器矫形扩张后,鼻腔在正面和横向尺寸上均呈三角形扩张。上颌扩张器宽度增加导致气道容积增加。

Changes in the nasal and pharyngeal airway volume with miniscrew-assisted rapid palatal expansion appliances
The purpose of this study was to assess the volumetric changes in the nasal and pharyngeal airway volume in patients with maxillary transverse deficiency treated with miniscrew-assisted rapid palatal expansion (MARPE) appliances. The pre- and post-treatment cone-beam computed tomography scans of 20 subjects who underwent treatment with the MARPE appliance as part of their orthodontic treatment were included in the study. Pre- and post-expansion airway volume measurements of the nasal cavity, nasopharynx, and oropharynx were measured. Linear measurements of the skeletal structures surrounding the nasal cavity were taken to assess the pattern of airway expansion. Paired t-tests were used to evaluate nasal and pharyngeal airway volume changes with expansion. Pearson correlation test was utilized to assess the relationship between nasal and pharyngeal volume changes. A total of 17 out of 20 samples had a successful split of the mid-palatal sutures. A significant increase in nasal airway volume (12.0%) was found post-expansion. In addition, a significant increase in linear measurements of the nasal cavity base width in the frontal plane (7.1%) and both the anterior and posterior widths in the transverse dimension (9.4% and 3.4%, respectively) were found. Significant positive correlations were found between airway volumes and increase in width of the maxillary expansion appliance. The effects of maxillary expansion with a MARPE appliance include an increase in nasal cavity volume, but not the nasopharyngeal and the oropharyngeal airway volume. The nasal cavity expands in a triangular pattern in both the frontal and transverse dimensions following orthopedic expansion with the MARPE appliance. Increase in airway volume is a result of the increase in width of the maxillary expansion appliance.
