A 62-year-old man suffered a penetrating injury to his left periorbital region with a wooden foreign body. He consulted an ophthalmologist and plastic surgeon. He was diagnosed with a conjunctival laceration and blowout fracture. His conjunctiva was consequently sutured. One month after injury, he consulted our clinic for diplopia. Severly limited trading in the upper and lower directions were observed.
Computed tomography (CT) and Magnetic resonance imaging (MRI) revealed an orbital floor fracture. When we performed an anterior orbitotomy, a 50 mm long, 10 mm wide wooden foreign body covered with granulation tissue in the orbit was found which had penetrated the maxillary sinus. It was removed from the orbit. In this case, wooden foreign body could not be identified preoperatively.
Key words : wooden foreign body, orbit, maxillary sinus
