Abstract
The author reported two cases of unilateral chronic sinusitis which were induced by unusual conditions.
The first case was a 59-year-old female who seeked medical aid because of nasal obstruction and bleeding from the right nasal cavity which lasted for seven years.
A rhinological examination revealed an embedded molor tooth obstructing the right middle nasal meatus where bleeding persisted from.
X-rays revealed an under-developed right maxillary sinus with marked clouding. This case was surgically treated and the postoperative course was uneventful.
The second case was a 54-year-old male who had a bleeding mass in the right middle nasal meatus, which was found to be a fungus ball (aspergillus).
Irrigation of the right maxillary sinus which had marked clouding roentogenologically produced profuse caseous substance.
An X-ray examination seven months later revealed a clear maxillary sinus without evidence of antral contents.
