Endoscopy permits visualization of the endolaryngeal spread of laryngeal tumors, yet the depth of tumor infiltration often remains unclear. The authors used high-resolution sonography in 37 patients with advanced laryngeal cancer to assess the tumors and the cervical lymph nodes. Sonographic findings were compared to operative and histologic reports. Sonography demonstrated histologically confirmed infiltration into the thyroid (n = 8) and cricoid cartilages (n = 1), preepiglottic space (n = 12), base of the tongue (n = 4), hypopharynx (n = 8), subglottic space (n = 3), and thyroid gland (n = 2). Except for the retrolaryngeal portion of the tumor, sonography was valuable in assessing extralaryngeal spread of advanced cancers. It enabled detection of subclinical lymph node metastases in four patients. Furthermore, invasion of the wall of the carotid artery was found in two patients. For evaluating the endolaryngeal and hypopharyngeal portions of the tumor, endoscopy remains mandatory.
内镜检查可观察喉肿瘤的喉内扩散情况，但肿瘤浸润深度往往仍不明确。作者对37例晚期喉癌患者使用高分辨率超声检查来评估肿瘤及颈部淋巴结。将超声检查结果与手术及组织学报告进行比较。超声检查显示组织学证实肿瘤浸润至甲状腺（n = 8）、环状软骨（n = 1）、会厌前间隙（n = 12）、舌根（n = 4）、下咽（n = 8）、声门下间隙（n = 3）及甲状腺（n = 2）。除肿瘤的喉后部分外，超声检查在评估晚期癌症的喉外扩散方面很有价值。它能够检测出4例患者的亚临床淋巴结转移。此外，发现2例患者的颈动脉壁受侵。对于评估肿瘤的喉内及下咽部分，内镜检查仍然是必不可少的。
