摘要: 目的: 利用锥形束CT(cone beam computed tomography, CBCT)从三维方向上研究强支抗拔牙内收对双颌前突青少年上气道的影响。方法: 回顾分析本院50例予以强支抗拔牙治疗的双颌前突青少年治疗前、后的CBCT资料,测量治疗前、后上气道的变化。采用SPSS 17.0软件包对数据进行配对t检验和Pearson相关性分析。结果: 治疗后,口咽和咽下的体积、平均截面积、最小截面积显著减小(P<0.001);口咽、咽下的横截面形态更趋于椭圆形(P<0.001)。Pearson相关分析发现,下颌切牙内收、舌骨后移与咽下气道平均截面积减少有显著相关性(P<0.05);上、下颌切牙内收与舌骨后移有显著相关性(P<0.01)。结论: 对于青少年双颌前突患者,制订治疗计划时应兼顾上气道形态,避免造成上气道狭窄,影响患者正常发育。

Abstract: PURPOSE: To investigate the effect of maximum anchorage on upper airway in adolescent patients with bimaxillary protrusion and extraction from three-dimensional direction on cone-beam computed tomography(CBCT). METHODS: A retrospective evaluation was carried out on pre- and post-orthodontic treatment records of 50 adolescents with bimaxillary protrusion treated by maximum anchorage extraction. The changes on upper airway pre- and post-treatment were measured. The data were analyzed using SPSS 17.0 software package. RESULTS: It was found that the volume, mean cross-section area, minimum cross-section area of oropharyngeal and hypopharyngeal airway were significantly decreased after treatment (P<0.001). The cross-section morphology of oropharyngeal and hypopharyngeal airway showed more ellipsoid(P<0.001). Pearson's correlation analysis indicated that the lower incisor retraction and hyoid retraction was correlated with mean cross-section area of hypopharyngeal airway (P<0.05). There was significant correlation in the upper and lower incisor retraction and hyoid retraction(P<0.01). CONCLUSIONS: The upper airway dimension should be given serious consideration on the decision when closing the space with maximum anchorage in adolescent patients.
