One of the indications of the surgical approach of the temporomandibular joint is the presence of foreign body in its interior. However, joint handling offers risks, especially bleeding. In these cases, angiography and embolization of the arteries involved with the projectile play an important role in the prevention of complications. In this report, the authors describe a case of a 23-year-old male victim of firearm attack with comminuted fracture of the right mandibular condyle. The patient underwent angiography and prophylactic embolization of the arteries adjacent to the foreign body. A surgical procedure was performed to remove the projectile and bone fragments with the aid of the X-ray image intensifier, which resulted in the restoration of mandibular function, absence of joint pain, and satisfactory dental occlusion. This case shows the importance of auxiliary imaging methods for performing a safe surgical procedure for removal of ballistic and bony fragments from the interior of the temporomandibular joint.
