[Tumors of the facial sinuses].

Nasal cavity and paranasal sinus carcinomas represent a small number of head and neck tumors (3 to 4%). Their management has been improved by modern imaging techniques to define operative procedures and deliver high-precision radiotherapy. Surgery is one of the most important components of treatment. Postoperative radiotherapy is indicated in all circumstances. A large proportion of patients with unresectable disease must be treated exclusively with radiotherapy. Definition of target volumes should be performed according to the knowledge of the natural outcome of the disease and modern 3D imaging. This is mandatory for treatment planning. Conformal radiotherapy significantly reduces the rate of complications, mainly eye toxicity.
