The perforative and incisive wounds of orbita include injuries with metallic substances like bullet and shrapnel pieces, tiny glass pieces, and stone or wood pieces. Particularly the wounds localized inside the orbita can lead to serious clinical consequences, even the removal of the eye.
A 65-year-old male patient was admitted to our hospital with the complaints of pain, bruise, blurry sight and difficulty in looking. A bullet, shotted towards the air during a wedding ceremony, had entered his right orbita. A detailed radiological examination was performed to assess the localization of the bullet and the damage it caused to the orbita and periorbital tissues.
When lateral head graphy and contrasted spiral BT scans evaluated together, a 5-millimeter foreign substance from a bullet was detected. It was located in the right orbita, but there was no signification extent into the cranium. Due to streak artifact caused by the foreign substance, the damage to the adjacent tissues could not be evaluated effectively in spiral BT. By the establishment of MPR and 3D images through BT sectional images, the streak artifact was eliminated, and the localization of the bullet, the linear fracture it caused in the zygomatic area of the right frontal bone and the damage to the adjacent tissues were displayed in details. Since the bullet was metallic, MRG examining could not be performed.
In conclusion; in orbita wounds due to a metallic substance such as a bullet and shrapnel piece, the streak artifact which affects the evaluation negatively can be eliminated by the establishment of MPR and 3D images through spiral BT sectional images. Accordingly, the method contributes to obtain detailed information about the trauma caused by the foreign piece, and to determine the type of operation being performed.Keywords: Wounds, gunshot; orbital fractures; radiography; tomography, spiral computedTurkiye Klinikleri J Ophthalmol 2007, 16:141-144
