Abstract
41 year old male, a case of foreign body in the right maxillary sinus was reported.
The material of foreign body was dental instrument, a broach. He was treated twice in his right maxillary carious teeth, first 28 years ago (1939), and secondly 15 years ago (1952). Without any symptom the broach had been left in the maxillary sinus as long as 15 years, and was fortuitously detected at hospital when he complained of headache.
Many cases of the maxillary sinus foreign body were reported, but few in which it was left for such a long time as in our case.
