Among the patients whose first visit with nasal complaints to the Tokyo Women's Medical College Daini Hospital occurred between January 1993 and December 1995, cysts were detected by CT in the postoperative paranasal sinuses of 95 patients.
These patients were compared to 42 patients without cysts in postoperative paranasal sinuses.
1) The presence of nasal discharge and ocular symptoms was of diagnostic value in cases of postoperative paranasal sinus cyst.
2) Nasal discharge was related primary to the presence of postoperative paranasal sinus cysts.
3) The presence of nasal polyps was not related to postoperative paranasal sinus cysts.
4) The presence of nasal polyps alone was of no diagnostic value in detecting postoperative paranasal sinus cyst, with the excepting of cysts located in the maxillary sinus.
