Nasal Polyps and Their Relation to Polyps/Hypertrophic Polypoid Mucosa in the Paranasal Sinuses: A Macro-, Endo-, and Microscopic Study of Autopsy Materials

Abstract

The present study comprised macro- and endoscopic screening of the nasosinusal complex in 56 autopsies, 24 with nasal polyps and 32 without. Seven had nasal polyposis (bilaterally more than two). Hypertrophic polypoid mucosa in the paranasal sinuses was not found in the cases with nasal polyposis and in only 2 (4%) of the total number (24) of cases with polyps. Microscopic examination of nine small polyps, the mucosa from which they originated, and control specimens showed accumulation of eosinophils in the mucosa from which the polyps originated, indicating localized inflammation.
