Abstract
Twenty cases of papilloma of the nasal cavity and paranasal sinuses treated at our facility for 13 years from 1977 to 1989 were studied. For each of these cases, clinical signs, macroscopic tumor appearance, treatment modality, operative findings, pathological features and prognosis were examined. As a result of this study, the following observations were made; 1. No characteristic clinical signs were noted for nasal and paranasal papilloma. Macroscopic tumor appearance at the time of initial examination was most useful for diagnosis, the following features being highly suggestive of papilloma;(a) tumors with an irregular surface and variable sized granular appearance;(b) poorly transparent salmon-pink tumors tinged with white,(c) tumors with a friable surface and ready tendency to bleed, but lacking crusts and ulceration. When suspected to be papilloma by macroscopic findings, a biopsy is requisite. 2. Total excision of the tumor by lateral rhinotomy is a method of choice. 3. There were broad-based and pedunculated tumors. 2 cases originating in the nasal septum demonstrated broad-based tumors. 8 cases demonstrating pedunculated tumors. 6 originated in the middle turbimate 1 each originated in the maxillary sinus and ethmoid sinus. 4. On light microscopy, both inverted papilloma and exophytic papilloma was combined in the same case. No correlation existed between macroscopic growth pattern and histopathological findings.
