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 endoscopic-assisted 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.
Highlights
The pathogenesis remains unclear, assumptions have been made about the process, such as tissue interactions during tooth development, which can be due to developmental disturbances, trauma, iatrogenic, pathology, and genetic factors [1]
According to a literature review of 51 ectopic teeth in the maxillary sinus by Lombroni et al [2], the majority of cases presented with symptoms including headache, facial pain, epistaxis, purulent rhinorrhea, swelling, and epiphorarelated nasolacrimal duct obstruction with 15 cases associated with pathology, mostly being a dentigerous cyst
This study presents various cases of an ectopic maxillary third molar, which was successfully removed using an innovative technique, modified endoscopic-assisted sinus surgery (MESS), and aims to emphasize the role of the endoscopic approach for removing ectopic teeth in the maxillary sinus
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. A tooth may exist in the maxillary sinus with or without symptoms. The treatment for an ectopic tooth with symptoms and/or pathology was surgical removal. Even though an asymptomatic ectopic tooth usually does not require surgical removal, it may develop into a cyst or tumor if left untreated [2]. The Caldwell-Luc procedure (CLP) has been used to remove teeth or foreign bodies from the maxillary sinus since this surgical approach provides good access through the canine fossa [4]. This study presents various cases of an ectopic maxillary third molar, which was successfully removed using an innovative technique, modified endoscopic-assisted sinus surgery (MESS), and aims to emphasize the role of the endoscopic approach for removing ectopic teeth in the maxillary sinus
