Abstract
A case of an inverted tooth in the maxillary sinus was reported. The patient was a 56-year-old man who presented with cheek pain of the left side. Computed tomography showed a tooth-like mass in the left maxillary sinus. Thereafter, the patient underwent endoscopic endonasal surgery. The mass was located posteriorly in the antrum. A small hole was made at the lateral wall of the inferior meatus and the mass was directly removed with forceps through the hole. The mass was diagnosed as an inverted tooth and the patient's complaint of cheek pain immediately disappeared. We considered that this approach was less invasive than the conventional approach. In this paper, the relation of the surgical approach to the site of the inverted tooth are discussed.
