Emergency And Acute Medicine – Facial Fractures
Overview And Definitions
Facial fractures result from blunt trauma most commonly caused by motor vehicle collisions, assaults, or falls. These injuries frequently involve multiple facial bones and are often associated with damage to adjacent structures including the eyes, teeth, mandible, cervical spine, and brain. Open fractures are common, and facial trauma may be the initial indicator of more severe systemic injury. In women and children, clinicians should maintain a high index of suspicion for physical assault or domestic violence.
Etiology And Mechanisms Of Injury
Facial fractures are categorized based on the anatomic structures involved. Le Fort fractures represent classic maxillary fracture patterns. Le Fort I fractures involve a horizontal separation of the maxilla above the teeth. Le Fort II fractures are pyramidal in shape, extending through the nasal bridge, maxilla, and infraorbital rims. Le Fort III fractures result in craniofacial disjunction with complete separation of the midface from the cranial base. Some patients may sustain asymmetric or mixed Le Fort patterns.
Other common fractures include zygomatic arch fractures, which may involve the orbit and maxilla, frontal sinus fractures that may be complicated by cerebrospinal fluid leaks, and orbital fractures, particularly blow-out fractures of the orbital floor that are frequently associated with ocular injury.
Special Populations
In older adults, facial fractures most commonly result from falls, with the zygoma being the most frequently fractured bone. These patients are at increased risk for concomitant cervical spine and intracranial injuries. In children, facial fractures are uncommon before the age of six; when present, nonaccidental trauma must be considered. Pediatric facial fractures are often associated with severe head injury, and orbital fractures are the most common non-nasal facial fracture in this population.
Clinical Presentation
Patients typically present with facial pain, swelling, ecchymosis, deformity, epistaxis, facial numbness, and malocclusion. Cerebrospinal fluid rhinorrhea, raccoon eyes, and facial anesthesia may indicate more severe injury. A septal hematoma appears as a bluish, fluctuant swelling of the nasal septum and represents a true emergency due to the risk of cartilage necrosis.
Physical Examination
Initial assessment must prioritize airway patency. A thorough facial examination includes palpation for tenderness, step-offs, crepitus, and deformity. Evaluation of dental occlusion, nasal inspection for septal hematoma or cerebrospinal fluid leak, and detailed sensory testing of the face are essential. A comprehensive eye examination including visual acuity, pupillary response, extraocular movements, and funduscopic evaluation is mandatory. Le Fort fractures can be assessed by stabilizing the nasal bridge while gently mobilizing the maxilla to detect midface instability.
Diagnostic Evaluation
After airway stabilization, radiologic evaluation is required for all suspected facial fractures. Computed tomography of the facial bones with multiplanar reconstruction is the imaging modality of choice and allows detailed assessment of fracture patterns and associated injuries. Plain radiographs are generally insufficient and should not be relied upon when CT imaging is available.
Differential Diagnosis
Conditions that may mimic or coexist with facial fractures include nasal fractures, isolated zygomatic fractures, mandibular fractures, frontal sinus injuries, skull base fractures, orbital soft tissue injuries, and facial contusions or lacerations without underlying bony injury.
Management Principles
Airway control takes precedence in all patients with facial trauma. Rapid-sequence intubation is preferred when airway protection is required, while nasotracheal intubation is contraindicated in most facial fractures. Surgical airway access may be necessary if standard intubation fails. Cervical spine immobilization must be maintained until injury is excluded.
Antibiotics are indicated for open fractures and cerebrospinal fluid leaks, and tetanus prophylaxis should be updated. Septal hematomas must be drained promptly in the emergency department. Pain control is achieved with parenteral analgesics. Consultation with otolaryngology, plastic surgery, oral surgery, or neurosurgery is required depending on fracture complexity.
Disposition And Follow Up
Patients with airway compromise, significant associated trauma, Le Fort II or III fractures, cerebrospinal fluid leaks, posterior table frontal sinus fractures, or most open fractures require admission. Stable patients with closed, nondisplaced fractures and no associated injuries may be discharged with close specialist follow-up within 24 to 36 hours. Septal hematomas require re-evaluation within 24 hours after drainage.
Clinical Pearls And Pitfalls
Facial fractures may appear dramatic but should never distract from airway management and evaluation for life-threatening injuries. Nasotracheal intubation should be avoided. Ocular injuries are common and must be actively sought. Always examine for a septal hematoma. Missing teeth must be accounted for, and aspiration should be excluded with chest imaging when indicated.
