Implants displaced into the maxillary sinus, an endoscopic approach - a report of two cases

Abstract

Accidental implant displacement into the maxillary sinuses and accompanying complications are well documented in the literature. Two surgical approaches have been suggested to remove the displaced implants and to handle the related complications: an intraoral approach and the nasal endoscopy. The intraoral approach is preferred in cases of absence of local infection, ostium obstruction, and oroantral communication needing to be closed.
 The nasal approach, besides retrieval of displaced implants, allows the treatment of any associated pathology and reestablishment of the mucociliary clearance as well as the natural ventilation through the ostium.
 This article reports two clinical cases of implant displacement in the maxillary sinus treated with a nasal endoscopy through the middle meatal meatotomy.

 Implants accidentally displaced can be avoided by a proper exploration of the preoperative x-ray, selecting an appropriate treatment plan, and esteeming the surgical skills. The most appropriate approach to handle these complications is close cooperation between oral surgeons and otolaryngologists.
