THE HIGH incidence of malignant tumors in the maxillary and paranasal sinuses is due to the complex embryology and to the peculiar anatomy of this region. The complex embryology gives rise to tumors as a result of developmental anomalies, e. g., paradental epithelial debris (Malassez and Galippe). The peculiar anatomy—bony cavities with minute orifices—offers a favorable soil for the growth of tumors (papilloma, carcinoma) on the basis of inflammatory processes (Ewing).
Benign tumors encountered in this region are the following:
1. Fibromas of the antrum and the ethmoidal sinus.
2. Osteomas, usually pedunculated, occurring as exostoses of the frontal sinus and of the articular head of the ramus of the mandible. Exostoses of the frontal sinus may cause pressure symptoms in the form of visual disturbances; those of the articular head of the ramus, difficulty of mastication.
3. Chondromas of the maxillary and pharyngeal vault.
4. Angiomas. Arterial racemose angioma
