作者1981～1986年综合治疗头颈部癌42例,其中喉咽癌28例、喉癌9例、舌癌3例、甲状腺癌2例。在放疗-手术后、手术-放疗后、术前放疗后或术后放疗前做轴位 CT 扫描。结果:①放疗或手术后对颈部软组织的影响如急性期浮肿或慢性期纤维化可较长期间出现在 CT图象上,至少需观察6个月。了解这种过程变化,才能判断肿瘤有无复发;②重建的咽腔,其皮瓣含脂肪组织,显示为低密度。易于与周围组织区分。如低密度中出现高密度区,提示为肿瘤复发;⑧CT 偶可发现局部复发和颈部复
The author comprehensively treated 42 cases of head and neck cancer from 1981 to 1986, including 28 cases of hypopharyngeal carcinoma, 9 cases of laryngeal cancer, 3 cases of tongue cancer, and 2 cases of thyroid cancer. Axial CT scans were performed after radiotherapy - surgery, surgery - radiotherapy, preoperative radiotherapy, or postoperative radiotherapy. RESULTS: 1 The effects on soft tissue of the neck after radiotherapy or surgery, such as acute edema or chronic fibrosis, may appear on CT images for a long period of time. At least 6 months of observation are required. Only by understanding this process change can we judge whether or not the tumor has recurred. 2 In the reconstructed pharyngeal cavity, the flap contains fatty tissue and shows low density. Easy to distinguish from the surrounding organization. If high density areas appear in low density, suggesting tumor recurrence; 8 CT may find local recurrence and neck recurrence
