[X-ray imaging in assessing the extent of laryngeal cancer].
Partiel surgery of the larynx for cancer should achieve the same carcinological control as total laryngectomy, while at the same time preserving the voice and swallowing. Establishing the extent of the tumour and its relationships with the anatomical structures of the larynx allows a treatment plan to be formulated. Decisions are taken in the light of investigation in which modern imaging plays a fundamental part. The authors have made a comparison of the relative value of CT scanning and MRI as a function of the area involved in the lesion. At present MRI is required only when there is uncertainly of the extent of the subglottic extension, or invasion of the cartilages. We give a prediction of the development of the technique of vitual endoscopy, which will yield a three-dimensional view of the relationships between the tumour and the cartilaginous structures.
