TOMODENSITOMETRIE DU LARYNX: ASPECT NORMAL ET PATHOLOGIQUE TUMORAL; EVALUATION DE L'APPORT SPECIFIQUE DE LA METHODE

Computed tomography has proved itself as the radiological examination of choice with regard to the evaluation of the extent of a laryngeal tumour and the possibilities for surgery. A comparative study carried out in 16 patients has analysed the contributions of three diagnostic methods: indirect laryngoscopy, conventional radiology, and computed tomography. Indirect laryngoscopy, together with computed tomography is the optimal diagnostic procedure; the former to study the mucosal lesions, the latter to ascertain the spread into surrounding subglottal tissue.
