Foreign bodies in the paranasal sinuses are rare and mostly related to maxillo-facial trauma. We treated a 47-year-old man with a late complication arising from a foreign body in the nasoethmoid sinus present for 16 years after a road traffic accident. Patients presenting with maxillo-facial injuries, especially those with lacerations due to glass or car wind-screen trauma should have thorough examination and appropriate imaging of the injury.
