A novel nasal endoscopic approach for removing displaced dental implants from the maxillary sinus.

Introduction: Over the last 30 years, dental implants have become widespread all over the world. Though the implantation procedure is standardized and safe, the displacement of implants into the maxillary sinus can occur. The aim of the study has been to describe a novel combined nasal endoscopic approach through the middle and lower meatus for managing dental implants displaced into the maxillary sinus. Methods/Results: A 40-year-old man was examined for a titanium osteo-integrated implant displaced within the alveolar recess of the left maxillary sinus. The indications and procedure are reported in detail. The pros and cons of this approach are compared with those of other standard surgical methods. Conclusions: The main strength of the technique described here lies in the ample view and ideal control of the displaced dental implant achieved by fashioning a second window at the lower meatus that enables enlargement of the natural ostium to be minimized, thereby ensuring an anatomically and functionally better result.
