Most of the foreign bodies are associated with maxillofacial trauma. Foreign body in the frontal sinus is even a rarer condition. Foreign bodies usually present with chronic symptoms and complications due to the delayed diagnosis. In this article, we report an unusual case of mucocele resulting from silicone nasolacrimal duct tube in right frontal sinus which was left or forgotten in nasal cavity after external dacryocystorhinostomy operation. The patient was treated surgically and her symptoms resolved after surgery.}, number={6}, publisher={Istanbul University}
