Case Reports
Maxillary sinusitis caused by dental implants extending into the maxillary sinus and the nasal cavities.
This report describes the case of a patient who underwent osseointegrated dental implant placement. The implants were misplaced inside the nasal fossae and in the right maxillary sinus, causing chronic purulent sinusitis. ⋯ The patient underwent functional endoscopic sinus surgery with complete symptom remission at the long-term follow-up. We propose that sinusitis caused by protrusion of implants and by sinus floor lift procedures could share common physiopathological patterns and predisposing factors.
