近期研究表明肿瘤厚度（侵犯深度）是影响口腔癌预后的重要因素，屹其叮作为区域淋巴结转移的一个预测指标，但迄今仅限于通过术后组织学初片进行测量。该作者首次试用口内超声显像术前检测舌癌的肿瘤范围和厚度，24例舌癌患者，男16例,女8例，年龄32～77岁，TNM分期为TNM～T4N Recent studies have shown that tumor thickness (invasion depth) is an important factor affecting the prognosis of oral cancer, Yi Ding as a regional lymph node metastasis of a predictor, but so far limited to the first postoperative histological measurement. The authors first used oral imaging to detect the extent and thickness of tongue cancer before operation. Twenty-four patients with tongue cancer, 16 males and 8 females, aged 32 to 77 years, had TNM stage of TNM to T4N
