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 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.

Appropriate Implant Rehabilitation in Patients With Iatrogenic Oroantral Fistula and Odontogenic Maxillary Sinusitis

“…8 The main advantage of MESS is that the physiological functions of paranasal sinus are maintained while avoiding the formation of postoperative maxillary cysts or sinus scar tissues. 7 A previous study by Han et al 9 demonstrated the successful outcomes of MESS through histopathologic and ultrastructural findings indicating the regeneration of SM and complete bone healing with clinical restoration of maxillary sinus functions that were achieved optimally 6 months after the treatment. 9 Periodic radiographs and clinical follow-ups are important to ensure that the maxillary sinus is normalized before proceeding with implant treatment.…”

“…We used MESS before implant rehabilitation as the treatment of choice for our 9 cases with various entities including odontogenic maxillary sinusitis, OAF, mucous retention cyst (MRC), fungal maxillary sinusitis, and oronasal fistula. MESS versatile application has been reported in several articles for the intraoral reduction of blowout orbital fractures,5 management of MRC,6 removal of ectopic third molar in the maxillary sinus,7 and removal of implant beneath the optic canal 8. The main advantage of MESS is that the physiological functions of paranasal sinus are maintained while avoiding the formation of postoperative maxillary cysts or sinus scar tissues 7.…”

The Bone Lid Technique in Oral and Maxillofacial Surgery: A Scoping Review

“…After a first screening of the titles and abstracts, a total of porting results of clinical studies on patients that underwent oral surgery combination with the use of the bone lid technique were selected. After eva full-text of these articles, 21 of them were excluded [7,8,13,16,[23][24][25][32][33][34][35][36][37][38][39][40][41][42][43][44][45] for exclusion are listed in Table 2. A total of 20 studies published in the ye were included.…”

Functional rehabilitation of the maxillary sinus after modified endoscopic sinus surgery for displaced dental implants

“…Although these transnasal endoscopic approaches may appear to allow easy access to identify and remove the foreign body from the maxillary sinus, it can be difficult to remove or even identify displaced dental implants that are located in the anteroinferior part of the sinus [ 7 , 11 , 13 , 14 ]. In contrast, the MESS approach can overcome this complication and identify the migrated dental implant in any part of the sinus with endoscopic assistance through a bony window placed in the anterolateral wall [ 5 , 6 ].…”
