目的:观察热塑性头颈肩膜开窗技术对喉癌急性放射性皮炎的保护作用。方法:将73例恶性肿瘤患者随机分为开窗组(38例)和对照组(35例)。开窗组将头颈肩膜中放射野相应区域剪去,射野中心使用激光延长线摆位放疗;对照组保留完整头颈肩膜,常规使用激光“十”字投射点摆位放疗。观察并比较两组放射性皮炎的发生率及照射野皮肤的疼痛程度。结果:开窗组放射性皮炎的发生率较对照组明显降低(P<0.05),且开窗组照射野皮肤的疼痛程度也较对照组明显减轻(P<0.05)。结论:热塑性头颈肩膜开窗技术能有效减轻喉癌放疗患者急性放射性皮炎的发生。
Objective: To observe the protective effect of thermoplastic head and neck fenestration technique on acute radiation dermatitis in laryngeal cancer. Methods: 73 patients with malignant tumor were randomly divided into fenestration group (38 cases) and control group (35 cases). In the fenestration group, the corresponding area of the radiation field in the head and neck shoulder membrane was cut away, and the radiotherapy center was extended with the laser extension line. The control group retained the complete head and neck shoulder and routinely used the laser “10” projection spot radiotherapy. Observe and compare the incidence of radiodermatitis and pain in the irradiated field skin. Results: The incidence of radiodermatitis in the fenestration group was significantly lower than that in the control group (P <0.05). The degree of pain in the fenestration group was also significantly reduced compared with the control group (P <0.05). Conclusion: Thermoplastic head and neck fenestration technique can effectively reduce the incidence of acute radiation dermatitis in radiotherapy of laryngeal cancer.
