PENETRATING KNIFE IN THE MAXILLARY SINUS: REPORT OF A RARE CASE.

Presence of foreign bodies in the paranasal sinuses are not common findings. Many cases have been reported so far with foreign bodies like dental amalgam, chopsticks, gutta percha pellets, tooth, glue and even bullets. However, presence of foreign bodies in the maxillary sinus as a result of penetrating trauma is uncommon. Most of them have been the results of trauma after vehicle accidents, gunshot injuries and assaults. There are two treatment options ? endoscopic and open surgical approach for the removal of sinus foreign bodies. We present a rare case of the transfacial penetrating injuries of maxillary sinus caused by a knife.
