| 目的 应用高频超声观察正常成人声门旁间隙（PGS）并测量其正常厚度值。方法 选取正常成人共240例，其中男女各120 例，共480侧PGS。入组者又再分为18～44岁、45～59岁和≥60岁3组。根据甲状软骨板的骨化程度，将声像图上软骨板骨化灶长度“小于软骨板1/3全长”、“介于1/3与1/2全长”、“大于1/2全长”，分别对应于PGS“优”、“良”、“差”的显示情况。对PGS显示为“优”和“良”者进行厚度测量。结果 各组室带平面PGS显示优于声带平面（75.0%～98.1% vs 38.5%～95.4%），且不因年龄、性别而异；随着年龄增加，PGS超声显示质量逐渐降低（83.3%～98.1% vs. 38.5%～91.9%）。室带平面测量男性PGS厚度为（2.24±0.25）mm，女性为（2.10±0.31）mm，声带平面测量男性PGS厚度为（1.69±0.21）mm，女性为（1.61±0.26）mm，差异均有统计学意义（均P＜0.01）；且年龄增加，PGS厚度也随之增长。结论 高频超声在室带和声带平面能显示大部分正常成人的PGS并可测量厚度值，在室带平面、中青年女性显示和测量PGS尤佳。 |

| Abstract: |
| Objective: To investigate the visualization capability of ultrasonography in adult paraglottic space (PGS) and measure the depth of PGS at the planes of ventricular band and vocal cord.
Methods: 240 adults were enrolled with diseases in the larynx and hypopharynx area excluded, including 120 men and 120 women, and divided into 18～44 years, 45～59 years, and ≥60 years group. The visualization capability of the PGS was evaluated at the planes of ventricular band and vocal cord, by grading criteria of “excellent”, “good”, and “poor” according to the degree of thyroid cartilage calcifications. The depth of PGS was measured in the adults with visualization capability categorized as “excellent” and “good”.
Results: The visualization capability of the PGS was better in the plane of ventricular band than that of vocal cord (75.0％～98.1％ vs 38.5％～95.4％). Also that was better in female adults compared with the male (61.4%～98.1% vs 38.5%～91.2%). The visualization capability of the PGS was degraded with age increased (83.3%～98.1% vs 38.5%～91.9%). PGS was thicker in the planes of ventricular band than that of vocal cord (male adults, 2.24±0.25mm vs 1.69±0.21mm; female adults, 2.10±0.31mm vs1.61±0.26mm, both P＜0.001). Male adults, the group aged 45～59 years, and ≥60 years tend to have thicker PGS when compared with their counterparts.
Conclusions: The PGS can be well visualized in most normal adults by using high-frequency sonography. At the plane of ventricular band, the female, and the young and middle-aged group have better visualization quality of PGS. Normal depth values of the PGS are obtained. PGS is thicker at the plane of ventricular band, especially in male adults and in the middle-aged and old people. |
