目的 利用三维影像扫描和重建技术、三维头影测量技术,比较骨型Ⅰ类和Ⅱ类正畸患者口咽气道的三维结构差异.方法 根据研究对象的骨面型分为骨型Ⅰ类组和骨型Ⅱ类组,年龄、性别严格匹配、均角研究对象共22对.将所有研究对象正畸初诊时拍摄的全头颅CBCT影像导入Dolphin Imaging 3D软件进行三维重建并分别测量其口咽气道、腭咽气道、舌咽气道的气道容积、气道长度、最小横截面积、最小横截面矢状径、横径及其比例关系,对两组间的气道指标进行统计学分析比较.结果 骨型Ⅱ类患者的舌咽气道最小横截面积[(144.27±68.30) mm2]及口咽气道最小横截面矢状径[(8.28±2.58) mm]较骨型Ⅰ类患者[(193.93±71.54) mm2,(9.76±2.22) mm]小(P≤0.05).结论 骨型Ⅰ类和Ⅱ类患者口咽气道三维结构具有一定差异,矢状骨型对口咽气道结构具有一定影响.
目的 利用三維影像掃描和重建技術、三維頭影測量技術,比較骨型Ⅰ類和Ⅱ類正畸患者口嚥氣道的三維結構差異.方法 根據研究對象的骨麵型分為骨型Ⅰ類組和骨型Ⅱ類組,年齡、性彆嚴格匹配、均角研究對象共22對.將所有研究對象正畸初診時拍攝的全頭顱CBCT影像導入Dolphin Imaging 3D軟件進行三維重建併分彆測量其口嚥氣道、腭嚥氣道、舌嚥氣道的氣道容積、氣道長度、最小橫截麵積、最小橫截麵矢狀徑、橫徑及其比例關繫,對兩組間的氣道指標進行統計學分析比較.結果 骨型Ⅱ類患者的舌嚥氣道最小橫截麵積[(144.27±68.30) mm2]及口嚥氣道最小橫截麵矢狀徑[(8.28±2.58) mm]較骨型Ⅰ類患者[(193.93±71.54) mm2,(9.76±2.22) mm]小(P≤0.05).結論 骨型Ⅰ類和Ⅱ類患者口嚥氣道三維結構具有一定差異,矢狀骨型對口嚥氣道結構具有一定影響.

Objective To study and compare the 3D structural differences of oropharyngeal airway between sagittal skeletal class Ⅰ and Ⅱ patients by 3-dimensional imaging,reconstruction and measurement.Methods 22 paired patients who were of vertical skeletal class Ⅰ and strictly matched according to age,gender,were divided into sagittal skeletal class Ⅰ and Ⅱ groups.Patients' CBCT image data at first visit were reconstructed by Dolphin Imaging 3D software.Then airway volume,minimum axial area and airway length of oropharyngeal,velopharyngeal and glossopharyngeal airway,anteroposterior and lateral length of the minimum axial area were measured and compared.Results The minimum axial area of glossopharyngeal airway in skeletal class Ⅱ patients [(144.27 ± 68.30) mm2] and anteroposterior of length minimum axial area [(8.28±2.58) mm] were significantly smaller than that of skeletal class Ⅰ patients [(193.93±71.54) mm2,(9.76±2.22) mm](P≤0.05).Conclusions Skeletal class Ⅰ and Ⅱ patients present different oropharyngeal airway structures.Skeletal patterns influence on oropharyngeal airway structure.
