Abstract
Most diseases of the nose and paranasal sinuses are of inflammatory origin and do not require sophisticated diagnostic or therapeutic management. In some cases, however, there are complications of paranasal sinus infections involving the orbit (complicated ethmoid or frontal sinusitis) or the meninges (pyocele of the frontal sinus). These complications require immediate surgical intervention. A large number of benign and malignant tumors of the nose and paranasal sinuses have been reported. Malignant tumors of these sites account for 0.2%–0.8% of all malignancies in human beings: that means, for instance, that one new case of maxillary sinus carcinoma is diagnosed per 200 000 persons per annum. The majority of the malignomas (75%) are squamous cell carcinomas and adenocarcinomas. Malignant tumors of mesenchymal origin make up 15%.
