The radiological service for otorhinolaryngology in a British subregional centre has been altered by the availability of a general purpose C.T. scanner. Two years' experience with the scanner is reviewed with an attempt to assess how aspects of the improved imaging affected management of patients. The greatest benefit has been in the demonstration of lesions in the perinasal region and C.T. is now the next investigation of choice after plain sinus films, virtually replacing conventional tomography. Computed tomography seems to have little to offer at present for the management of laryngeal lesions, and multidirectional tomography is still the most important means of investigating the temporal bone, despite the difficulty in interpreting the thin low-contrast sections. A simple protocol for the investigation of acoustic neuromas, and a means of certainly excluding the presence of one by demonstrating the structures within the internal auditory meatus, is described.
英国一个次区域中心的耳鼻喉科放射服务因一台通用计算机断层扫描（CT）扫描仪的投入使用而发生了改变。回顾了使用该扫描仪两年的经验，试图评估改进后的成像在哪些方面影响了患者的治疗。最大的益处在于能够显示鼻周区域的病变，如今CT已成为继鼻窦平片之后的首选检查手段，几乎取代了传统体层摄影。目前，计算机断层扫描在喉部病变的治疗方面似乎作用不大，尽管难以解读薄层低对比度图像，但多向体层摄影仍是颞骨检查的最重要手段。本文描述了一种听神经瘤检查的简单方案，以及通过显示内耳道内的结构来确定排除听神经瘤存在的方法。
