In order to determine the value of sonography (US), in staging cancer of the mobile tongue, 57 patients were studied prospectively. Real-time sector scanners (5 and 7.5 MHz) were used with a submental approach. The findings by US were compared with those obtained by inspection and palpation and in 13 operated patients with the surgical results. US failed to visualize the tumor in 3 of the 57 patients (5%); in 30 patients (53%), the tumor was considered to be of nearly the same size by US and by palpation, but in 17 cases (30%), to be larger by US than by palpation, and in the remaining 7 cases (12%), to be smaller by US. Extension across the midline (8/8), and depth of tumor penetration, or extension to adjacent structures (5/5) were more correctly evaluated by US. We conclude that US is useful for staging work-up of tumors of the mobile tongue.
为了确定超声检查（US）在活动期舌癌分期中的价值，我们对57例患者进行了前瞻性研究。采用颏下途径，使用实时扇形扫描仪（5兆赫和7.5兆赫）。将超声检查结果与视诊和触诊结果进行比较，并将13例接受手术的患者的超声检查结果与手术结果进行比较。57例患者中有3例（5%）超声未能显示肿瘤；30例患者（53%）超声检查显示的肿瘤大小与触诊结果相近，但17例（30%）超声显示的肿瘤大于触诊结果，其余7例（12%）超声显示的肿瘤小于触诊结果。超声更能准确评估肿瘤是否越过中线（8/8）、肿瘤浸润深度或是否侵犯相邻结构（5/5）。我们得出结论，超声有助于活动期舌癌的分期检查。
