Abstract
We present a case in which a misplaced implant fixture in the maxillary sinus was removed by means of endoscopic sinus surgery.
A 57-year-old man was referred to Azabu Kitami Triology Hospital because of misplacement of his implant fixture. At the first visit, there was an oro-antral fistula in the right upper molar region,without surrounding inflammation. Radiographical examinations, including CT, revealed the misplaced fixture in the right maxillary sinus, and thickening of mucosa of the sinus.
Under general anesthesia, endoscopic sinus surgery was performed.
Endoscopic examination showed that the fixture was embedded in edematous mucosa. The fixture was successfully removed, along with the surrounding edematous mucosa, by means of endoscopic sinus surgery.
Operation time was only 20 minutes, and blood loss was little, and also there was no marked postoperative inflammatory reaction.
The healing was uneventful, and there was no evidence of sinuitis at 12 months after the surgery.
Endoscopic sinus surgery seems to be a very useful procedure for removal of a foreign body in the maxillary sinus.
