Abstract

<p>In recent years, cases of sinusitis associated with dental implants (DIs) have increased in number in Japan. In fact, in some patients, the DI need to be surgically extracted. A 52-year-old man with three right maxillary DIs presented to our hospital complaining of right cheek pain. Sinus CT revealed right maxillary sinusitis with severe periodontitis and peri-implantitis. We made a diagnosis of odontogenic sinusitis and proposed extraction of the teeth and DIs causing the inflammation. We extracted two teeth, while the patient refused to undergo extraction of the DIs. He visited the hospital again after 2 months complaining of cheek pain; we ruled out a successful outcome with endoscopic sinus surgery (ESS) alone, and repeatedly proposed extraction of the DIs. Finally, he consented to undergo extraction of one DI showing severe peri-implantitis and ESS, following which he recovered.</p><p>Local infection of peri-implant tissue is the most common complication of DIs, and in such cases, extensive resorption of the bone surrounding the implant may occur. Odontogenic maxillary sinusitis may be caused by peri-implantitis, DI displacement, or maxillary sinus augmentation surgery. Patients at risk of odontogenic sinusitis can be identified by consultation between a rhinologist and dentist before DI therapy.</p>
