    AbstractGunshot wounds of the viscerocranium are a rare occurrence during times of peace in Europe. The removal of projectiles is recommended; in some cases, however, this is controversial. The material properties of projectiles and destruction of anatomical landmarks make it difficult to determine their precise location. Therefore, navigation systems and cone-beam computed tomography (CT) provide the surgeon with continuous intraoperative orientation in real-time. The aim of this study was to report our experiences for image-guided removal of projectiles, the use of cone-beam computed tomography and the resulting intra- and postoperative complications. We investigated 50 patients with gunshot wounds of the facial skeleton retrospectively, 32 had image-guided surgical removal of projectiles in the oral and maxillofacial region, 18 had surgical removal of projectiles without navigation assistance and in 28 cases we used cone-beam CT in the case of dislocated projectiles and fractured bones. There was a significant correlation (p = 0.0136) between the navigated versus not navigated surgery and complication rate (8 vs. 32%, p = 0.0132) including major bleeding, soft tissue infections and nerve damage. Furthermore, we could reduce operating time while using a navigation system and cone-beam CT (p = 0.038). A high tendency between operating time and navigated surgery (p = 0.1103) was found. In conclusion, there is a significant correlation between reduced intra- and postoperative complications including wound infections, nerve damage and major bleeding and the appropriate use of a navigation system. In all these cases we were able to present reduced operating time. Cone-beam CT plays a key role as a useful diagnostic tool in detecting projectiles or metallic foreign bodies intraoperatively.
