摘　　要：目的 研究骨性上颌发育不足青少年上气道形态及周围结构的特征.方法 64例9～13岁恒牙早期青少年经头影测量分析,其中诊断为骨性上颌发育不足的患者32例,矢状和垂直骨面型均正常的青少年32例.所有研究对象均拍摄X线头颅定位侧位片行头影测量及上气道间隙分析.应用SPSS 10.0统计软件包,行独立样本t检验比较骨性上颌发育不足青少年与正常骨面型青少年的上气道形态及其周围结构的差异.结果 骨性上颌发育不足青少年的鼻咽气道、腭咽气道间隙以及口咽腔面积明显小于正常骨面型青少年（P＜0.05）.结论 骨性上颌发育不足青少年与正常骨面型青少年相比,上气道形态及周围结构存在差异.Objective To determine the influence of chin on extraction in borderline cases.Methods Pre-treatment lateral cephalograms of 50 treated patients （25 first premolar extraction cases, 25 non-extraction cases） were collected and digitized. The average pre-treatment age was 16.5 years （15～18 years）. 19 cephalometric parameters were used for assessment. Comparison was made between extraction and non-extraction orthodontic treatment in borderline cases. The correlation analysis, t-test and Logistic regression analysis were used. Results Significant hard tissue changes were found between extraction and non-extraction cases. Extraction cases had smaller chin prominence. Logistic regression analysis showed that the probability of orthodontic extraction was significantly correlated with Pog-NB. Conclusions The important factor in determining extraction in borderline cases was the prominence of the chin. The probability of orthodontic extraction decreased with the increasing chin prominence.
