Displacement of maxillary third molar into the infratemporal fossa. A case report

Our study aims to present a new case of maxillary third molar dislodgement into the infratemporal fossa during the effort of extraction and the surgical approach performed to retrieve the tooth. Guidelines to prevent this complication are presented. We describe a new case of maxillary third molar displacement into the infratemporal fossa following an unsuccessful surgical procedure of tooth removal by a general dentist. The location of the displaced tooth was confirmed with computed tomography (CT) scanning with a 3D reconstruction. The tooth was removed under general anesthesia through an intraoral approach. It took less than 10 min for the whole procedure to be accomplished. CT examination is of paramount importance to precisely locate the dislodged tooth. Removal can be successfully accomplished via an intraoral approach with meticulous manipulations. An incision of adequate length and a long Langebeck retractor are valuable to ensure a wide surgical field.
