Rhino-sinusitis related to endosseous implants extending into the nasal cavity. A case report

Rhino-sinusitis may develop as a result of an altered airflow in the nasal cavity causing irritation of the nasal mucosa. A patient is presented who developed recurrent rhino-sinusitis complaints following placement of endosseous implants in the maxilla. Inspection of the nasal floor revealed that two implants had perforated the floor of the nasal cavity. The part of the implants protruding in the nasal cavity was surgically resected via an endonasal approach whereupon the rhino-sinusitis complaints disappeared.
