PurposeHead-injured patients admitted to a trauma center may or may not have associated facial fractures. Most head-injured patients undergo head computed tomography (CT) scan early in their evaluation. The question of adding a facial CT at the time of the head CT can be unclear. The aims of our study are 1) to analyze how the facial CT is used in conjunction with the head CT in facial fracture trauma patients, 2) to recognize unique identifiers that would aid the surgeon's decision-making process to order a facial CT in continuity with a head CT, and 3) to examine what is characteristic of head trauma patients who receive a facial CT separately, at some point after the head CT. Materials and methods Data were retrospectively reviewed for a 5-year period at a level I trauma center in which all patients who present with craniomaxillofacial trauma are managed by the oral and maxillofacial surgery (OMFS) service. Included patients must have obtained a head CT during initial resuscitation and be diagnosed with a facial fracture during the same hospital stay. These patients were divided into 3 groups: those who had a 1) head CT only, 2) head CT and facial CT at the same time, and 3) head CT with the facial CT performed at a later time.ResultsA total of 9,871 patients were admitted to the trauma service during a 5-year period and 4,926 patients (49.9%) had head CT performed. Of this group, 12% had facial fractures, and the most common associated injury in this group was facial lacerations and concussions. The nasal fracture followed by the orbital fracture was the most common fracture type. Eighty-four percent of the time, the facial CT was used to help diagnose facial fractures in this patient population. The 3 different groups showed unique trends.ConclusionSix points were identified in our study that can augment the physical examination in patients who require head CT. The following points can help prompt the clinician to order a combination head and facial CT: 1) 12% of trauma patients who require a head CT will have a facial fracture, whereas half of these patients will have multiple facial fractures. 2) Orbital fractures are commonly missed in this group and often require a secondary scan such as coronal views for accurate diagnosis. 3) Facial lacerations correlate with ordering a combination head and facial CT. 4) The most common facial fracture identified among patients receiving a trauma head CT is the nasal fracture. 5) The use of the facial CT in more severely injured patients tended to be delayed and was related to increased hospital and intensive care unit days. 6) Only 16% of facial fracture patients who had received an initial trauma head CT did not require further facial CT scanning.
