A Case of Foreign Body Incidentally Found at the Maxilla and Maxillary Sinus

Foreign bodies in the maxillary sinus are rare and mostly of traumatic origin.These foreign bodies result in pain, bleeding and infection and are immediately removed in most cases.Sometimes the foreign body without serious symptoms can remain for several years without treatment.However, the prognosis of foreign bodies in the paranasal sinuses can be severe.Therefore, regardless of the symptoms present, it seems worthwhile to remove the foreign body from the paranasal sinuses in order to prevent any possibility of further complications.The authors report a case of foreign body occurring in maxilla and maxillary sinus without symptoms for 25 years with related literatures.
