[Computerized axial tomography in ORL diseases. Indications and advantages (author's transl)]

Computerized axial tomography enables the accurate diagnosis of acoustic neuromas by non-invasive means, and it should therefore be used after conventional radiological methods. Small neuromas often only show non-specific signs and in these patients contrast cysternography is still necessary. Up to the present glomus jugulare tumours were diagnostically confirmed by angiography. Now the CT scan is recommended not only for diagnosis, but also for after-treatment follow-up and recognition of recurrent tumour growth. Tumours that infiltrate the skull base should be assessed by this method since the extent of the lesion can be exactly measured.
