Modified endoscopic‐assisted approach for removal of ectopic third molar in the maxillary sinus

Abstract

This case series describes an alternative approach for removing ectopically erupted tooth in the maxillary sinus using an improved endoscopic approach known as modified endoscopicassisted sinus surgery (MESS). We reviewed medical charts and radiographs of patients who underwent surgical removal of an ectopic tooth in the maxillary sinus using MESS. The surgical technique consisted of creating a bony window in the maxillary sinus wall with a pre‐adapted microplate, which was repositioned after the tooth was removed. For all the patients included in this study, there were no postoperative complications clinically and radiographically. At the time of microplate removal, satisfactory bone regeneration was observed around the bony window margins of the maxillary sinus wall. MESS is an effective technique that modifies and integrates the techniques of the conventional Caldwell‐Luc procedure (CLP) and functional endoscopic sinus surgery (FESS) and can be used to remove ectopic tooth in the maxillary sinus by avoiding the risk of postoperative sinus‐related complications.
