The statement that is NOT true is ג: Ohngren's line concerns SINONASAL (maxillary sinus) malignancy, not salivary gland tumours. It runs from the medial canthus to the angle of the mandible, dividing the maxilla into a suprastructure and an infrastructure, and tumours above and behind the line - closer to the orbit, skull base and pterygoid region - carry a significantly worse prognosis because of early involvement of those structures.
