Abstract

<p>Iatrogenic foreign bodies can cause maxillary sinusitis. Herein, we report two cases of patients in whom gutta-percha, a filling material used in root canal treatment, was identified as a foreign body in the right maxillary sinus. Gutta-percha is commonly used in dentistry, and occasionally it penetrates the root apex to stray into the maxillary sinus. CT is commonly used for the diagnosis, but caution is required, as it could be missed, depending on the site at which it is lodged. Treatment is surgical removal, which may be difficult depending on the location. In both the cases reported herein, we performed endoscopic resection, with good outcomes. Gutta-percha points can cause maxillary sinusitis, and it is important to diagnose and treat these patients without leaving any residual foreign body or residual postoperative symptoms.</p>
