This study compared the area and minimal section of the nasal cavity, nasopharynx, oropharynx, and hypopharynx in cases treated with different methods of microimplant-assisted expansion.
Based on a pilot study to calculate the sample size, 30 patients with transverse maxillary deficiency over 14 years of age were retrospectively selected. These patients had received two different types of microimplant-assisted maxillary expansion treatment (MARPE and BAME). The patient underwent Cone-Beam computed tomography (CBCT) before and after treatment (mean time 1.5 months) with MARPE or BAME and upper airway measurements (volume and minimum cross-sectional area) were taken to assess upper airways changes and compare changes between the groups. A paired sample t-test was performed to evaluate the T0-T1 change of airway measurements obtained with MARPE and BAME, and a student t-test to compare changes in airway measurements between MARPE and BAME.
This investigation shows a statistically significant increase in total nasopharyngeal airway volume (0.59 ± 1.42 cm3; p < 0.01), total oropharyngeal airway volume (3.83 ± 7.53 cm; p < 0.01) and minimum oropharyngeal cross-section (53.23 ± 126.46 mm; p < 0.05) in all cases treated with micro-screw assisted expansion. The minimal cross-sectional area of the oropharynx ((79.12 ± 142.28 mm2; p < 0.05) and hypopharynx (59.87 ± 89.79 mm; p < 0.05) showed significant changes for cases treated with BAME. As for the comparison between cases treated with MARPE and BAME, no differences in upper airway changes have been observed, except for the minimum cross-sectional area of the nasal cavity, which increases for MARPE (52.05 ± 132.91 mm2) and decreases for BAME (-34.10 ± 90.85 mm2).
A significant increase in total area and minimal section at the level of nasopharynx and oropharynx was observed in cases treated with BAME. Regarding the comparison of MARPE and BAME treatments, no differences were found in the total airway volume and minimal section in upper airway except for the minimum cross section of the nasal cavity that increases for MARPE and decreases for BAME.
本研究比较了经微种植体辅助扩展治疗的不同方法的鼻腔、鼻咽、口咽和下咽的面积和最小截面。
基于一项计算样本量的试点研究，回顾性选择了 30 名年龄超过 14 岁的横向上颌骨发育不全患者。这些患者接受了两种不同类型的微种植体辅助上颌骨扩展治疗（MARPE 和 BAME）。患者在接受 MARPE 或 BAME 治疗前后进行了锥形束计算机断层扫描（CBCT）（平均时间 1.5 个月），并测量了上呼吸道测量值（体积和最小横截面积），以评估上呼吸道的变化，并比较组间的变化。采用配对样本 t 检验评估 MARPE 和 BAME 获得的气道测量值的 T0-T1 变化，采用学生 t 检验比较 MARPE 和 BAME 之间气道测量值的变化。
本研究表明，所有接受微螺钉辅助扩展治疗的患者的总鼻咽气道容积（0.59±1.42cm3；p<0.01）、总口咽气道容积（3.83±7.53cm；p<0.01）和最小口咽横截面积（53.23±126.46mm；p<0.05）均有统计学显著增加。接受 BAME 治疗的患者，口咽和下咽的最小横截面积（79.12±142.28mm2；p<0.05）和（59.87±89.79mm；p<0.05）也有显著变化。对于 MARPE 和 BAME 治疗的病例比较，除了 MARPE 的最小鼻腔横截面积（52.05±132.91mm2）增加而 BAME 减少（-34.10±90.85mm2）外，上呼吸道的气道变化无差异。
接受 BAME 治疗的患者鼻咽和口咽的总面积和最小截面明显增加。关于 MARPE 和 BAME 治疗的比较，除了 MARPE 的最小鼻腔横截面积增加而 BAME 减少外，上呼吸道的总气道容积和最小截面无差异。
