The temporal bone often falls within the field of radiation for head and neck tumors. Whereas osteoradionecrosis is well recognized as the end-stage complication of radiation to the temporal bone, serious non-osteitic complications can also occur, and these are important because the ear is an organ of special sense. Radiation causes changes in the specialized tissues of the ear that can impair function and influence therapeutic decisions. The purpose of this article is to review the non-osteitic effects of radiation on the ear. A series of cases is presented that illustrate the spectrum of non-osteitic complications of radiation therapy. External canal stenosis, otitis media with effusion, chronic suppurative otitis media with or without cholesteatoma, sensorineural hearing loss, vestibular impairment, and facial nerve paralysis are described. Management should be guided by an understanding of the pathogenesis of these complications. The authors believe that non-osteitic complications of therapeutic radiation to the temporal bone are relatively common and warrant increased recognition.
颞骨常处于头颈部肿瘤的放射野内。虽然骨放射性坏死是颞骨放疗的终末期并发症已广为人知,但严重的非骨炎并发症也可能发生,而这些并发症很重要,因为耳是特殊感觉器官。放疗会引起耳部特殊组织的变化,这可能损害功能并影响治疗决策。本文的目的是综述放疗对耳部的非骨炎影响。文中呈现了一系列病例,以说明放射治疗非骨炎并发症的范围。描述了外耳道狭窄、渗出性中耳炎、伴或不伴胆脂瘤的慢性化脓性中耳炎、感音神经性听力损失、前庭功能损害及面神经麻痹。应基于对这些并发症发病机制的理解来进行处理。作者认为,颞骨治疗性放疗的非骨炎并发症相对常见,值得更多关注。
