According to the literature, 60% of paranasal sinus FB are of iatrogenic origin, while 25% are of traumatic origin. This article aims to present an iatrogenic origin series of cases of FB displaced or projecting into the maxillary sinus.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>In this retrospective study, the presence of the foreign body was revealed with radiologic methods and confirmed during the operation with macroscopic or later with histopathologic examination.

Foreign body was displaced fragments of teeth in 11 patients (40.27%), complete teeth in four patients (14.81%), dental implants in five patients (18.51%), dental impression material in 2 cases (7,40%), gutta percha cone in two patients (7.40%), endodontic sealer associated with aspergillosis in two patients (7.40%), and dental burr in one patient (3.7%).
