Abstract
Sino-nasal cancers are a rare pathology, with an incidence of 0.2-0.8% of all cancers, and less than 5% of ENT cancers. The site that is most often affected is the maxillary sinus in 35% of cases, followed by ethmoid sinus (30%) and of the nasal cavity in (16%). Several histological variants are described, but squamous cell carcinoma remains the most frequent in the maxillary sinus. Its diagnosis is often late making local control very difficult. Multimodal treatment allows an improvement in the survival rate compared to single treatment. Due to the progress of endoscopic surgery, external surgery is neglected. With this work we want to highlight the value to the external approach, especially in advanced cases.
