Ohngren's line is seen in
A theoretic plane passing between the medial canthus of the eye and the angle of the mandible; used as an arbitrary dividing line in classifying localized tumours of the maxillary sinus; tumours above the line invade vital structures early and have a poorer prognosis, whereas those below the line have a more ourable prognosis. Growths of the maxillary sinus(carcinoma of maxillary sinus) situated above this plane(suprastructural) have a poorer prognosis than those below it(intrastructural).
