为了术前准确地确定肿瘤侵犯的范围,以选择正确的治疗方法和手术方案、现代影像学技术对喉癌的术前评价就显得至关重要。本文结合近年来国内外文献,就CT和MR在喉癌外科治疗中的作用予以介绍。 1 喉癌的临床与影像学诊断技术 随着部分喉切除术的开展,术前准确勾画肿瘤的范围和侵犯的深度就显得尤为重要,几乎所有喉的恶性肿瘤都发生在粘膜表面,易直接显示和活检。喉内窥镜和活组织检查为诊断喉癌的重要手段。喉镜显示粘膜表面肿瘤的位置、形态及大小并能推测癌侵犯的范围,结合活检,为喉癌定性诊断可靠
In order to accurately determine the scope of tumor invasion before surgery to select the correct treatment and surgical options, modern imaging techniques for the evaluation of laryngeal cancer is crucial. This article combines the domestic and foreign literature in recent years, CT and MR in the surgical treatment of laryngeal cancer to be introduced. 1 laryngeal cancer clinical and imaging diagnostic techniques With the partial laryngectomy carried out preoperative accurate outline of the scope of the tumor and the depth of invasion is particularly important, almost all of the laryngeal malignancies occur in the mucosal surface, easy to directly display And biopsy. Throat endoscopy and biopsy are important ways to diagnose laryngeal cancer. Laryngoscope shows the location, shape and size of mucosal surface tumor and can infer the scope of cancer invasion, combined with biopsy, for the qualitative diagnosis of laryngeal cancer is reliable
