Management of Iatrogenically Exposed Maxillary Sinus with a Broken Periosteal Elevator Trapped Inside

Abstract

Foreign bodies may be ingested after being inserted into an oral cavity or deposited in the body by traumatic or iatrogenic injury. Accidentally left out foreign materials are common complications of dental procedures including apical deposition of endodontic materials, sub‑mucosal amalgam pieces, graphite tattoos and traumatically introduced dental materials and instruments. Once a foreign material is left behind within a soft and/or hard tissue, it promotes local inflammation and infection that may cause pain and/or destruction within the surrounding tissues. This article presents a case of retrieval of iatrogenically broken periosteal elevator trapped in the maxillary sinus.
