Abstract
Tumours in the nasal cavity and paranasal sinuses were recognized during the time of Hippocrates. Whillis (1948) defined tumours as “an abnormal mass of tissue, the growth of which exceeds and is coordinated with that of the normal tissues and persists in the same excessive manner after cessation of the stimuli which evoked the Change. From the table I it is evident that only 5 cases of malignant and 3 cases of fungal Granuloma, there was bony erosion. In 19 cases of antro chonal polyp and antrum and ethmoid sinus is found to be hazy. From the table I, on radiological study, sinuses are found to be hazy in 86.4% cases of antro choanal polyp and 89.4% cases of ethmoidal polyp. This finding is in accordance with that of miles (1971) who started that usually there is some degree of opacity of sinuses either due to thickening of mucosa or superadded infection. erosion of bone is found in 70% cases of malignancy and the 3 case of fungal granuloma.
