摘　　要：目的探讨超声检查鼻咽癌的可行性。方法以CT作为参照,对25例已确诊鼻咽癌的住院患者进行鼻咽部的超声检查:采用仰卧位,检查时头略向对侧倾斜,以腮腺及咽旁间隙作为透声窗,取下颌角和乳突间的耳垂下斜横断面和下颌骨升支旁的斜冠状切面显示鼻咽部,测量病理情况下鼻咽部软组织的厚度或范围,观察其形态、边界、内部回声及与周围组织的关系。然后用高频探头检查左右侧颈部,并对肿大的淋巴结测量记录。结果25例患者显示35个病灶,其中单侧病灶15例,双侧病灶10例。病灶显示低回声28个,中等回声6个,高回声1个;实质性回声32个,夹杂有无回声区3个;声像图表现鼻咽部软组织增厚20个,鼻咽部肿块15个;超声提示颈部淋巴结肿大16例,咽旁间隙浸润24例,骨质破坏2例。结论经颈超声可观察到鼻咽癌时鼻咽部软组织增厚或肿块声像表现,且超声对鼻咽癌侵犯咽旁间隙和淋巴结亦有较好的敏感性。Objective To study the feasibility of ultrasonic examination in nasopharyngeal caner. Methods CT being as contrast reference 25 cases of patients with nasopharyngeal cancer were examined with ultrasound at nasopharyngeal parts. Patients lied on their backs and turned their heads slightly to the side. The parotid and pharynx clearance served as sound penetrating window to show the nasopharyngeal part through the transect between lower law and lower earlobe, as well as coronary section near the uprising bone of the lower jaw. This could measure the thickness and scope of soft nasopharyngeal tissue under the condition of pathology. Operators could observe the shape, border, inner echo and connection with the surrounding tissue. Then high-frequency detecting sensor was applied to examine the left and right neck, and record the measurement of tumescence of the lymph node. Results The 25 patients showed 35 focuses, among which there were 15 cases developing with unilateral focuses, and 10 cases with double-sided focuses. Among the focuses, there were 28 focuses with medium and low echoes, 6 with medium echoes, 1 high echo. There were 32 cases with substantial echoes, and 3 cases developed with no echo section. Ultrasono graphics showed that 20 cases developed with nasopharyngeal soft tissue thickness increasing, 15 cases were found with nasopharyngeal tumour, and 16 cases with lymph tumescence on the neck prompted by the ultrasonic. Twenty-four cases developed with soakage in pharynx clearance, and 2 cases with osseous damage. Conclusions When applying ultrasound to examine nasopharyngeal cancer via the neck, the presentation of the thickness increasing of the soft nasopharyngeal tissue and the tumour image would be observed. It is very sensible to examine the offense of nasopharyngeal cancer to the pharynx clearance and lymph node.
