摘要： 目的:研究减数治疗对骨性Ⅰ类高角正畸患者上气道的影响。方法:依据颈椎分期,选取生长发育结束的骨性Ⅰ类高角患者26例,分为非拔牙组13例,男4例,女9例,年龄(17.62±3.45)岁;拔牙组13例,男3例,女10例,年龄(16.85±3.51)岁。测量分析颅面硬组织和上气道形态。结果:(1)治疗后,非拔牙组U1-NA(mm)、L1-NB(mm)增大;拔牙组U1-SN(°)、U1-NA(mm)、U1-NA(°)、L1-MP(°)、L1-NB(mm)、L1-NB(°)、MP-FH(°)减小,且差异均有统计学意义(P<0.05)。上气道、软腭、舌及舌骨在治疗前后比较无显著差异(P>0.05)。(2)非拔牙组与拔牙组治疗前后比较发现ΔU1-SN(°)、ΔU1-NA(mm)、ΔU1-NA(°)、ΔL1-MP(°)、ΔL1-NB(mm)、ΔL1-NB(°)差异有统计学意义(P<0.05)。两组间上气道、软腭、舌及舌骨治疗前后改变量无统计学差异(P>0.05)。结论:拔牙矫治对骨性Ⅰ类高角患者上气道形态无显著影响。

Abstract: Objective: To evaluate the morphology changes in the upper airway after premolars extraction in patients with ClassⅠhyperdivergent. Methods: 26 patients were selected,whose cervical morphology showed that growth was finished. 4 boys and 9 girls were included in the non-extraction group [average age: (17.62±3.45) years], 3 boys and 10 girls were included in the extraction group [average age:(16.85±3.51)years]. The hard tissues and upper airway were measured by the cephalometrics before and after treatment. The data were analyzed with statistical software. Results: After treatment, U1-NA(mm) and L1-NB(mm) increased significantly in the non-extraction group (P<0.05). The U1-SN(°), U1-NA (mm), U1-NA(°), L1-MP(°), L1-NB(mm), L1-NB(°), and MP-FH(°) decreased significantly in the extraction group (P<0.05). There were no significant differences in both groups for hard tissues, upper airway, tongue, and hyoid between pretreatment and posttreatment (P>0.05). ΔU1-SN(°), ΔU1-NA (mm), ΔU1-NA (°), ΔL1-MP(°), ΔL1-NB (mm), ΔL1-NB(°) changed significantly(P<0.05). There was no significant difference between the non-extraction and extraction groups in the changes of hard tissues, upper airway, tongue, and hyoid (P>0.05). Conclusion: The effects of premolars extractionon in upper airway morphology in patients with ClassⅠhyperdivergent was limited.
