Abstract

Three cases of iatrogenic foreign bodies in the maxillary sinus caused by dental treatment are reported. The patients comprised one man and two woman 34 to 66 years old. All patients were referred to us by the department of otorhinolaryngology of our hospital. Their primary dentists had not informed the patients about the foreign bodies. The foreign bodies were dental implants, a fractured instrument (reamer), and root canal filling materials. Maxillary sinusitis at the sites of the foreign bodies was seen in all patients at the initial examination. Each foreign body was surgically removed with the patient under general anesthesia. Recovery was uneventful after the operation.
