Worldwide, the reconstruction of the posterior edentulous maxilla with dental implants has become a common practice in clinical settings. However, the poor bone condition in this area is sometimes accompanied by complications. Dental implant displacement into the maxillary sinus is viewed as a rare complication. A case of a 72-year-old man in whom an endoscopic technique was used to remove a dental implant that had been mistakenly planted into the maxillary sinus was reported in this study. The authors approached the sinus through the inferior nasal meatus, and the dental implant was removed through the widened ostium. The endoscopic surgical approach described in this study is reliable and minimally invasive for removing residual roots displaced into the maxillary sinus. Therefore, it has been concluded that this clinical procedure is worth using.
