Surgery of the larynx not only allows reshaping the tumor but also to preserve maximally the laryngeal function. This is why the imaging gives an exact definition of the extent as well as the volume of the tumor. This is a retrospective study involving 58 patients performed at the ENT-head and neck surgery specialties hospital of CHU Rabat from January 2019 to December 2019.All patients with epidermoid carcinoma received cervical CT with axial and coronal slices and endoscopic (direct laryngoscopy) assessment. The realization of a computed tomography is used nowadays in common practice to review the loco regional extension of laryngeal cancers. It is an integral part of the staging with a crucial role in the mostly conservative therapeutic decision and monitoring [1, 2]. The exam should be performed remotely from biopsies, especially for small tumors. Indeed, the post-biopsy inflammatory reaction could falsely increase the tumor description. The decision of a suitable therapeutic attitude for each case of laryngeal cancer depends indeed on the sensitivity of endoscopic and scannographic examinations.
