Ciliary activity of mucosal cells of nasal polyps and the maxillary sinus mucosa in chronic sinusitis cultured in vitro were measured by a photoelectric method. The findings were compared with those of normal maxillary sinus and inferior turbinate mucosae. The ciliary beating of edematous type of nasal polyp, 955 ± 130 beats/min (mean ± SD), did not differ significantly from the normal control, whereas both the duration and rate of ciliary beating were significantly decreased with cystic and fibrous type polyps. Ciliary activity in chronic sinusitis was significantly inhibited in the order of fibrous, purulent, and edematous types. The total area of ciliated mucosa also was decreased and varied with the type of chronic sinusitis, showing the most marked decrease with fibrous type. The ciliary activity in chronic sinusitis showed impairment with respect to both decreased ciliary rate of beating and reduced ciliated area.

ABSTRACT Introduction Nasal polyps are pedunculated, edematous, prolapsed mucosa of the paranasal sinuses. These polyps commonly arise around the ostia of the paranasal sinuses in the middle meatus. Discussion The commonest sites of polyp formation are the ethmoid sinuses and maxillary sinus. Rarely polyps may also arise from the other paranasal sinuses. Sites in the nasal mucosa other than the paranasal sinuses are very rare, though polyps arising from the septum have also been reported. The etiology of nasal polyposis is believed to be due to an inflammatory reaction of the nasal and paranasal sinus mucosa. Conclusion In addition to the theory of altered airway dynamics in the middle meatus, there also appears to be a link between polyp formation and preceding chronic inflammation. This is the most likely explanation for the origin of polyps in unusual sites. We present here a case of a nasal polyp arising from the floor of the nasal cavity. There are no previous records or reports in literature of this unusual site of origin of a nasal polyp.
