目的观察比较70例双侧咽旁间隙侵犯的鼻咽癌患者采用两种不同照射方式治疗的疗效。方法 70例双侧咽旁间隙侵犯的鼻咽癌全部病例经病理和CT证实,随机分成两组:对照组和放疗组各35例。对照组采用面颈联合野放疗至36Gy,鼻咽改用双耳前野、耳后电子束野,颈部采用颈前分割野放疗。放疗组采用面颈联合野放疗至36Gy,自己设计的颈后分割野,并将颈后分割野提高扩大至外耳孔上缘,同时使用双外侧挡块保护双下颌支。结果治疗组咽旁肿物消退率明显高于对照组。结论对于双侧咽旁间隙受侵的鼻咽癌患者,我们设计改进的颈后分割野能明显提高疗效。

Objective To observe and compare the efficacy of two different irradiation methods in 70 patients with bilateral parapharyngeal space-borne nasopharyngeal carcinoma. Methods 70 cases of bilateral nasal pharyngeal parapharyngeal space all cases of nasopharyngeal carcinoma confirmed by pathology and CT, were randomly divided into two groups: the control group and the radiotherapy group of 35 cases. The control group was treated with face-neck joint field radiotherapy to 36Gy. The nasopharyngeal was switched to the anterior segment of the ears, the posterior eyelid of the ears, and the neck was divided by the anterior cervix. Radiotherapy group face-neck joint field radiotherapy to 36Gy, their own design of the posterior cervical spine field, and the back of the neck raised to expand the outer edge of the upper edge of the ear, while the use of double lateral occlusion double mandibular branch. Results The treatment group pharyngeal tumor regression rate was significantly higher than the control group. Conclusion For patients with nasopharyngeal carcinoma with bilateral parapharyngeal space involvement, we designed an improved posterior cervical spine segmentation to significantly improve the outcome.
