CA0087-Facial Fracture Mandible

History

34-year-old male in the emergency room following an altercation with possible mandibular or other facial fractures due to craniofacial trauma. CT

Exam

Non contrast CT of the maxillofacial region was obtained with 0.5-1.0 mm thick sections in the axial plane and reformatted 3D and/or in the coronal and sagittal planes and viewed interactively in 3 dimensions at the computer work station.

Findings

Facial and Scalp Soft Tissues and Airway

There is extensive soft tissue swelling along the mandible and within the submandibular space on the left side with some edema within the adjacent masticator space. There is gas in the soft-tissues at the mandibular fracture site likely due to associated oral mucosal injury with there being no definite evidence of penetrating injury.

There is soft tissue swelling surrounding the submandibular gland but no findings to suggest rupture of the salivary gland.

The upper airway is not significantly narrowed or obstructed.

Mandible and Temporomandibular Joints

There is a slightly distracted vertical fracture of the posterior mandibular body on the left, running through the inferior alveolar canal. The fracture runs anteriorly and inferiorly to the roots of the third molar, without definite fracture of the tooth roots or other portions of the tooth. There is also a fracture of the middle portion of the zygomatic arch, with presence of a small bony fragment. The distance between the coronoid process and the zygomatic arch is decreased, suggestive of possible entrapment of the temporalis muscle.

The mandible and temporomandibular joint regions otherwise appear normal.

Dentition

There is no evidence of dental fractures and/or missing or displaced teeth; although fracture does extend close to the root of the 3^rd molar.

Midface Structures and Orbit

There is no bony injury to the midface or orbit.

Intracranial

There is no evidence of intracranial injury.

Cervical Spine

The visualized portions of the cervical spine are normal.

Impression

Slightly distracted fracture of the posterior mandibular body on the left, extent described above.

Possible entrapment of the temporalis muscle due to a combination of the mandibular and zygomatic arch fracture on the left.
