Surgical management of a projectile within the temporomandibular joint

Endoscopy Assisted Removal of Post Traumatic Impacted Foreign Body in the Nose Extending into Opposite Parapharyngeal Space

The head and neck region is a complex anatomical area with vulnerable nervous and vascular structures, auditory and visual organs and upper aero-digestive tract. Penetrating foreign bodies of head and neck region are not uncommon and pertain mostly to wood, metal and glass (Levine et al. in Am J Emerg Med 26:918-922, 2008). This case report describes an airborne high velocity foreign body blown off from a lawn mower penetrating the left side of the face, penetrating deep into nasopharynx and opposite parapharyngeal space through paranasal sinuses. A multidisciplinary team managed this case successfully, avoiding injuries to adjacent vital skull base structures.

Surgical Management of Gunshot Injury to the Temporomandibular Joint

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.
