本文就９例喉癌术前以纤维喉镜为主的临床检查、ＭＲＩ检查与全喉切除后连续全器官病理切片检查的结果进行了前瞻性对比研究。主要从声门下区、声带、室带、声门上区等四个平面比较，发现术前进行ＭＲＩ可清晰而较准确地显示肿瘤向会厌前间隙、声带旁间隙、喉软骨支架等部位的侵犯范围，其与术后全器官病理切片在判断病变范围方面的符合率（８８．９％）远高于纤维喉镜检查与病理的符合率（４４％）。 In this paper, nine cases of preoperative laryngeal cancer with fiber laryngoscope-based clinical examination, MRI examination and total laryngectomy after continuous organ biopsy results were prospective comparative study. Mainly from the subglottic area, vocal cords, ventricular zone, supraglottic area and other four planes, found that preoperative MRI can clearly and accurately show the tumor to epiglottic anterior gap, vocal fold space, throat cartilage and other parts of the site of violations The coincidence rate (88.9%) with total pathological sections in determining the extent of lesions was much higher than that of fibrolaryngoscopy (44%).
