摘要
目的研究生理状态下环杓关节的影像学特点。方法回顾性研究175例喉镜正常人群的上气道CT检查图像,根据年龄分组对杓状软骨钙化、杓状软骨骨质增生及环杓关节狭窄程度定性评估,探索其随年龄的变化趋势。评估声带长度、肌突旁间隙距离、环杓关节夹角等空间位置结构。结果杓状软骨钙化、杓状软骨骨质增生及环杓关节间隙狭窄程度在不同年龄组间存在差异。杓状软骨钙化(r=0.36,P<0.001)、杓状软骨骨质增生(r=0.49,P<0.001)及环杓关节间隙狭窄程度(r=0.54,P<0.001)均与年龄呈正相关。双侧声带长度和环杓关节夹角对称(P均>0.05)。结论正常人群环杓关节形态对称,随年龄增长逐渐钙化、增生及关节狭窄,上气道CT检查能够评估环杓关节的形态及空间位置,为临床提供解剖参考。
OBJECTIVE To study the imaging characteristics of the normal cricoarytenoid joint.METHODS A retrospective study was conducted on the upper airway CT images of 175 subjects with normal laryngoscopic findings.According to age groups,a qualitative evaluation was made of the calcification of the arytenoid cartilage(AC),the hyperplasia of the AC,and the degree of stenosis of the cricoarytenoid joint(CAJ).The study aimed to explore the changing trends of these factors with age.We evaluated the spatial position structures such as the length of the vocal cords(l-VC),the distance between the muscle process of the arytenoid cartilage and the thyroid cartilage(d-MPCC),and the angle of the cricoarytenoid joint(a-CAJ).RESULTS There were differences in calcification of AC,hyperplasia of AC and stenosis of CAJ among different age groups.The calcification of AC(r=0.36,P<0.001),hyperplasia of AC(r=0.49,P<0.001)and stenosis of CAJ(r=0.54,P<0.001)the were positively correlated with age.Bilateral l-VC and a-CAJ were symmetry(all P>0.05).CONCLUSION The morphology of the CAJ was symmetrical in the normal population.It gradually underwent calcification,hyperplasia,and stenosis with age.Upper airway CT examination could evaluate the morphology and spatial position of the CAJ,providing an anatomical reference for clinical practice.
