摘要
目的进行尸体喉部超声影像表现与其解剖-组织学的对比研究,为喉部超声检查提供正常的"参照系"。方法对14例成人尸体颈部标本进行喉部超声扫查,并制作解剖组织学大切片。将超声图像所示"亚结构"的外形与对应的组织大切片进行比较。结果软骨组织构成的甲状软骨、会厌软骨、杓状软骨、环状软骨均呈低回声,软骨膜呈线样强回声。除会厌软骨无骨化外,其余三种软骨均有不同程度的骨化区,呈强回声。声带肌(甲杓内肌)和弹性组织(膜)构成的声带呈对称的三角形低回声结构,其黏膜表面构成的游离缘呈线状偏强回声。主要由疏松结缔组织组成的室带呈对称的类三角形强回声结构。疏松结缔组织构成的会厌前间隙和声门旁间隙表现为偏强回声。结论喉部结构的超声征象取决于它们的解剖组织学基础,通过与组织大切片的对比,明确超声表现与解剖组织学表现的"一对一"关系,从而获得了"正常参照系"。
OBJECTIVE To investigate the sonographic appearance of larynx in adult cadavers and compare it with their histoanatomy.METHODS Fourteen adult cadavers were scanned using sonography focusing on the region of larynx.The ultrasound features of each region were compared with those of the corresponding histoanatomy.RESULTS 1.Laryngeal cartilages,including thyroid,epiglottic,arytenoid and cricoid cartilages,were hypoechoic structures.These cartilages were delimited bilaterally by hyperechoic lines,corresponding to the perichondria.The elastic epiglottic cartilages rarely undergo calcification,whereas all of the other three cartilages sometimes had calcification areas which were hyperechoic.2.Vocal folds,corresponding to the internal layers of thyroarytenoid muscles,were hypoechoic with a symmetrical and triangular structure.The thin mucous membrane appeared to be hyperechoic lines on the surface.False vocal folds manifested as the paired hyperechoic and triangular structures.Their echogenicity was related to the glandular and fat contents.3.Fat-containing spaces like the pre-epiglottic and paraglottic spaces were hyperechoic.CONCLUSION By means of comparative study between the sonographic and the histoanatomic appearances,the ultrasound features of normal larynx structures are identified,which could be used as a reference system for the future clinical application.
