The anatomy of the tongue and floor of the mouth is readily discernible by computed tomography (CT) because of low-density fascial planes that outline the extrinsic musculature, lingual arteries, and hypoglossal nerves. Although the tongue is accessible to the examining finger, few patients can tolerate a detailed palpation. In planning for a partial glossectomy, CT scanning aids the surgeon who must be sure that the tumor is unilateral or that at least one lingual artery and one hypoglossal nerve can be preserved. The CT scans of 30 patients were reviewed for background anatomy. Pathologic changes are summarized for 16 extrinsic lesions and 11 intrinsic tumors. The status of the midline could be confirmed in 28 of the 30 patients. The fascial plane distortions by malignant intrinsic and extrinsic lesions are discussed.
由于低密度筋膜平面勾勒出舌外肌、舌动脉和舌下神经，通过计算机断层扫描（CT）很容易辨别舌及口腔底部的解剖结构。尽管用手指可以触及舌头，但很少有患者能耐受详细的触诊。在计划进行部分舌切除术时，CT扫描有助于外科医生确定肿瘤是单侧的，或者至少可以保留一条舌动脉和一条舌下神经。回顾了30例患者的CT扫描以了解其背景解剖结构。总结了16例舌外病变和11例舌内肿瘤的病理变化。30例患者中有28例可以确认中线的情况。讨论了恶性舌内和舌外病变引起的筋膜平面扭曲。
