Endoscopic removal of a dental implant displaced into the maxillary sinus: Technical note

The management of complications following displacement of oral implants in the paranasal sinuses: a multicenter clinical report and proposed treatment protocols

“…Implant migration in the sinuses may not be followed by relevant signs and symptoms of infection, but it can be associated with oro-antral communication and/or infection that may involve the maxillary sinus and the ethmoidal, frontal and sphenoid sinus. These displaced foreign bodies should be removed as soon as possible to prevent such complications 10,12,13,15,18,19,20,27 . Two main treatment modalities have been proposed for the removal of displaced implants in the sinuses and to treat the associated infectious complications: an intraoral approach with the creation of a bony window in the anterior-lateral wall of the maxillary sinus 2,11,18,19,20 ; and a transnasal approach with functional endoscopic sinus surgery (FESS) 12,13,15,28,27 .…”

Surgical Alternative in Sinus Lift Reoperation

“…On the other hand, it may cause damage to infra-orbital nerve, retraction of cheek soft tissue, buccal-sinus fistula, and extensive damage in the sinus lateral wall and Schneiderian membrane [23,24].…”

Endoscopic transnasal removal of migrated dental implants

“…[1][2][3][4][5][6][7] Similarly, the ENT literature has sparse data and mentions a single study referring to endoscopic removal of dental implants. 8 The use of the trans nasal, trans-antral approach as the sole intervention has only been mentioned on four occasions.…”

“…1,4,6,10 More commonly, the trans-oral endoscopic approach was used. 2,3,7,8,11 A combined approach, trans nasal and trans-oral was also described. 9 Various other studies refer to the use of endoscopy for removal of other foreign bodies including amalgam and teeth roots amongst others.…”
