Tooth or implant may be displaced into the maxillary sinus in various reasons. Aim of this study is analyzing the foreign body into the maxillary sinus including the problems, appropriate treatments and describing some representative case reports.A 13-year retrospective analysis was performed in the Department of Oral and Maxillofacial Surgery, Seoul National University Bundang Hospital presenting with displacement of foreign body into the maxillary sinus. For each patient, medical records and radiographs were reviewed. In the three representative cases, signs and symptoms, treatment details, and pre post-operative radiographic evaluations were presented.Total 19 patients presenting with displacement of foreign bodies into the maxillary sinus. Sixteen cases (84%) were implant displacement while three cases (16%) were tooth. Half of the implants displacement occurred during the implant surgery and rest of them occurred after the surgery. Eleven cases (57.9%) were asymptomatic while eight cases (42.1%) showed symptoms. Psychological stress and nasal obstruction were the most common signs and symptoms. Attempts at removal of the displaced material were made 14 out of 19(74%) cases, 5 patients (26%) were observed with using antibiotics. For removal, majority of patients underwent the surgery with Caldwell-Luc approach under general anesthesia. All symptoms disappeared after removing the displaced material.Tooth and implants can be displaced accidentally, during or after the surgery. Once it occurs, patients showing symptoms treated by removal of the foreign body. Even asymptomatic patients, monitoring and regular check-up must be done whether it develops symptoms.
