This study investigated the presence of mast cells in inflammatory aural polyps
using light microscopy. The number of mast cells was increased in all examined
cases and varied from 2.33 to 41.54 per mm2• The cells were located most commonly
around small blood vessels. Occurrence of mast cells was not different in various
types of polyps, but their density was severely increased in active inflamed polypous
tissue. These findings suggest that mast cells may be a contributory factor in the
pathogenesis of middle ear inflammatory processes.
