Endoscopic removal of a maxillary third molar displaced into the maxillary sinus via the socket

Removal of a maxillary third molar is a common dental procedure, and oral surgeons rarely experience accidental displacement of a maxillary impacted third molar into the maxillary sinus as a complication of this procedure. In the case in which such displacement occurs, the molar is removed via a transantral (Caldwell-Luc) approach through bone removal or window osteotomy of the anterior wall of the maxillary sinus. However, this approach is highly invasive because 2 surgical fields are required at the socket and the anterior wall of the maxillary sinus. Here, we report as a minimally invasive approach endoscopic removal of a maxillary third molar displaced into the maxillary sinus via the socket.
