Endoscopic Medial Maxillectomy Approach for Removal of Ectopic Tooth in the Maxillary Sinus

Abstract

Objective: The occurrence of ectopic teeth involving the maxillary sinus reported in the literature remains relatively low. Instances of complications related to ectopic teeth in the maxillary sinus include associated dentigerous cysts, maxillary sinus mucoceles, chronic sinusitis, pain/pressure, and occasionally osteomeatal complex obstruction and nasolacrimal duct obstruction. Although the standard of care historically has involved a Caldwell-Luc approach, advances in endoscopic surgical approaches have led to use and report in the literature of both endoscopic and combined endoscopic and open approaches. In this study, we describe the specific use of the endoscopic medial maxillectomy to approach ectopic teeth within the maxillary sinuses of two different patients.
