摘要
[目的]探讨鼻咽癌患者放射治疗后分泌性中耳炎的发生,寻找有效的防治措施。[方法]观察104例（208只耳）鼻咽癌患者放疗前后分泌性中耳炎的发生。[结果]鼻咽癌患者放疗后分泌性中耳炎的发生率为44.1％（64/45只耳）。放疗后6个月,分泌性中耳炎的发生率达高峰,为 50.1％（33/64只耳）。放疗所致分泌性中耳炎与电离辐射对中耳的直接损伤和放疗前中耳负压升高有密切关系。[结论]改进放射治疗设野技术,使用有效药物,采取鼓膜置管和鼓膜切开等方法对防治分泌性中耳炎的发生有一定用处,但其耳瘘发生率很高。
[Purpose] To investigate the incidence and treatment of secretory otitis after radiotherapy in nasopharyngeal carcinoma . [Methods] Secretory otitis in 104 patients(208 ears) with nasopharyngeal carcinoma were observed before and after radiotherapy . [Results] Incidence rale of secretory otitis resulting from radiotherapy in nasopharyngeal carcinoma was 44. 1% (64/145 ears) .50. 1% (33/64 ears)of them occurred in 6 monthes after radiotherapy. Irradiation damage and increasing negative pressure in middle ear before radiotherapy may be closely associated with secretory otitis . [ Conclusion ] Secretory otitis is one of the causes which influence middle ear function after radiotherapy lor patients with nasopharyngeal carcinoma. Improvement of radiotherapy technique ,effective drug, ventilation tube insertion and myringotomy may be helpful in prevention of secretory otitis . But the incidence of otorrhea is very high.
