Abstract
The case is a 26-year-old female, who had a swelling in the left cheek late in March in 1985. On the first examination, a swelling was seen in the left cheek, but no abnormal findings in intranasal examination. Neither nasal obstruction nor rhihorrhea was seen. She had dull pain and ginvival swelling about the maxillary 5th tooth on the left. Sinus roentgenography revealed a difffuse shadow in the left maxillary sinus and the bone erosion in its lateral wall. Left maxillary sinusectomy was done under local anesthesia on May 23, 1985. Histopathologically, it was diagnosed a juvenile ossifying fibroma. She was discharged on June 1, and has been without recurrence.
