The route of spread of tumours originating in the anterior skull base and paranasal sinuses is determined by the complex anatomy of the craniofacial compartments. These tumours may invade laterally to the orbit and middle fossa, inferiorly to the maxillary antrum and palate, posteriorly to the nasopharynx and pterygopalatine fossa (PPF), and superiorly to the cavernous sinus and brain. Recent improvements in endoscopic techniques now allow the resection of benign neoplasms or malignant tumours with minor dural involvement. For advanced-stage malignant tumours and benign tumours with frontal bone involvement, the classical transfacial approaches remain viable surgical techniques.
