CBCT对上气道形态的研究进展

上气道为人体重要的组成部分,随着多种影像学手段的应用,对其认识逐步深入。以往研究有其局限性或不可靠性,目前锥形束CT(CBCT)已成为研究气道形态大小的主要手段。总结应用CBCT研究气道的多种气道划分标准、多种分析测量软件及方法,主要通过测量气道容积、长度、不同截面矢状径、横径和面积等项目,研究不同骨面型患者的气道特点,得出差异所在,用以指导气道疾病的治疗及错颌畸形的正畸正颌手术等。

Research Progress of CBCT on Airway Morphology

Upper airway is an important component of the human body. With the application of various imaging methods, it has been known deeply. Previous research has its limitation and unreliability, and now CBCT is becoming an useful method to study airway morphology and size. The present research progress at home and abroad are summarized. A variety of airway division standards, a variety of analysis and measurement software method are introduced. they investigated the difference of the upper airway morphology between different skeletal patterns mainly by measuring projects such as the airway volume, length, area, anteroposterior and lateral dimensions of cross-section, so as to guide the treatment of micromaxillary deformity and airway disease.
