头颈恶性肿瘤病人的颈淋巴结分期,仍然是所有头颈外科医生主要关心的问题,已报道的淋巴结转移假阴性率在0％～77％(平均20％～40％)。本研究对临床触诊颈淋巴结阴性并行颈淋巴结清除术的病人,术前进行超声及超声引导下细针抽吸细胞学检查,以评价该技术在发现颈淋巴结隐性转移中的效用。对107例未经治疗的触诊颈淋巴结阴性的头颈鳞癌行超声检查,该107例病人共接受132 Cervical lymph node staging in patients with head and neck cancer is still a major concern for all head and neck surgeons, and the false negative rate of reported lymph node metastases ranges from 0% to 77% (mean, 20% to 40%). This study of patients with clinically palpable neck lymph node-negative cervical lymph node dissection, preoperative ultrasound and ultrasound-guided fine needle aspiration cytology to evaluate the technology in detecting cervical lymph node implicit metastasis in the utility. 107 cases of untreated palpation cervical lymph node-negative squamous cell carcinoma of the neck underwent ultrasound examination, the 107 patients received a total of 132
