[Trans-facial and cranio-facial approach and resection of the skull base tumors].

The paranasal sinus cancers comprise about 10% of all head and neck neoplasms. There are 80% of SCC among them. Paranasal sinus cancer is difficult to treat with surgery due to the anatomic integration of sinuses into the cranial base. Suborbital approach allows to simultaneous resection of the tumor from sinuses and anterior cranial fossa. The excision of the nasofrontal bone lamella gives a chance to orbital decompression and optic nerve decompression as well and opening the anterior cranial fossa through posterior wall of the frontal sinus. The goal of the study was to present cases showing advantages and effectiveness of this kind of surgical procedure.
