A Case of Retained Wooden Sino-orbital Foreign Body
Myun Ku, Dong Heun Nam, Mi Jung Chi
To report an experience of retained wooden foreign bodies after primary surgery of penetrating eye injury. Methods: We found retained wooden intraorbital foreign bodies at the orbital inferior wall reconstruction surgery of a 33-year-old man complaining of persistent periorbital swelling, ocular pain and restricted eyeball movement after primary operation of ocular penetrating injury. Preoperative CT scan showed inferior orbital wall fracture and hypodense area in maxillary sinus. Results: In approaching to inferior wall, hard wooden mass and surrounding inflammatory tissue were found at the fractured site and maxillary sinus. The mass was grasped and withdrawn through inferior fornix. The residual conjunctival chemosis and pain subsequently resolved and limitation of movement of the right eye improved postoperatively. Conclusions: Retained orbital foreign bodies can cause serious complications including extraocular muscle restriction, diplopia, strabismus, orbital cellulitis, and abscess. Wood has a density similar to air and fat and can be difficult to distinguish from soft tissue in orbital computed tomography. Therefore, in cases where a inflammatory reaction sustained after primary surgery, the possibility of retained wooden orbital foreign body should be suspected.
