Maxillary fungus ball caused by retained foreign bodies for 25 years.

We present a case of a maxillary fungus ball caused by retained foreign bodies for 25 years. The patient sustained a stab wound in the left face 25 years ago. The patient had no symptoms and complications of a foreign body, until the patient went to the hospital. The fungus ball and foreign bodies were removed via an endoscopic and Caldwell-Luc approach. We suggest the need for careful inspection and radiologic studies to localize occult foreign bodies in the sinonasal cavity or facial soft tissues after facial trauma.
