Origin of Nasal Polyps: An Endoscopic Autopsy Study

The results seemed to indicate that the frequency of nasal polyps is high and that most of the polyps originate from the mucosa of the ostia, clefts, and recesses in the ostiomeatal complex where the initial stage of sinonasal polyposis seems to take place. Continuous postmortem studies in autopsy materials and systematic endoscopic examinations for "silent," asymptomatic nasal polyps in various groups of patients will lead to a better understanding of the natural history of nasal polyps.
