A case of self-inflicted intraorbital injury: wooden foreign body introduced into the ethmoidal sinus.

A patient with an intraorbital wooden foreign body is presented. A 43-year-old schizophrenic male patient purposely introduced a twig through his left medial canthus and into the orbital cavity 6 months before presentation. Magnetic resonance imaging showed a well-delineated intraorbital object that partially penetrated the ethmoidal sinus through the medial orbital wall. Under general anesthesia, a 55-mm-long and 6-mm-diameter twig was removed through an incision along the sulcus palpebromalaris. Thick capsule formation around the foreign body, fibrosis of the adjacent tissues, and severe infection were observed. Diagnosis and management of intraorbital foreign bodies are discussed.
