Removal of an Unusual Neglected Foreign Body in Infratemporal Region Using Navigation.

A 19-year-old male presented with complaint of a bluish mass in the hard palate since 3 months. The patient had a history of trauma 8 years back in the left zygomatic area with a pen. It was lodged in the wound and removed at that time. Computed tomography scan was revealed a linear heterogenous dense structure extending from left infratemporal fossa to oral cavity, traversing through left maxillary sinus, with bone defect seen in lateral and medial wall of maxilla, and in the hard palate, most likely a neglected foreign body. The foreign body was removed by navigation-assisted endoscopic surgery and the palatal perforation repaired using local rotation flap. There were no intraoperative or postoperative complications. Navigation-guided removal of foreign body in proximity to vital structures, in the infratemporal region, is a valuable option with minimal morbidity.
