Abstract
We examined 34 patients with nasal and paranasal papilloma between April, 1984 and May, 1992. The results obtained are as follows ; 1) The average age of the patients was 58. 1 years. Men were affected more frequently than women, in a ratio of 4:1. 2) One-sided nasal obstruction was the most common symptom, although expansive growth of the papilloma caused exophthalmos or blurred vision. 3) Histopathologically, 5 cases were exophytic type and 29 cases were inverted type. Six cases showed malignant change. 4) Six out of thirty cases showed recurrence. And three cases out of them showed malignant change to carcinoma.
