  • Conventional or high resolution multidetector computed tomography (CT) is the gold standard for the radiographic evaluation of patients with facial trauma

  • Plain films are no longer a routine part of diagnostic imaging of patients with facial trauma

  • Imaging is not indicated for simple nasal fractures

  • Cone beam CT (CBCT) and ultrasonography (US) are emerging imaging modalities in assessing maxillofacial injuries

  • Ultrasonography (US) has shown high sensitivity and specificity in evaluating maxillofacial fractures. However, its use has been mainly limited to nasal and orbital traumas and is not recommended in acute and emergency settings

Status Of Recommendations Each pathway is designed to assist clinicians in situations when faced with a large array of possible diagnostic tests and examinations. However, it is recognised that diagnostic practice may differ from a particular pathway depending on local availability of equipment and expertise, as well as the experience of individual clinicians. Therefore each pathway is neither a rigid set of rules, nor a substitute for clinical assessment, and individual patient circumstances should always be considered.

Facial Trauma

Facial fractures are often classified by upper face fractures (including fracture of the frontal bone and orbital roof), midface fractures (including nasal, orbital, maxillary, zygomatic bones, and more complex Le Fort fractures), and mandible fractures

  • Facial fractures are often classified by upper face fractures involving the frontal bone and orbital roof; midface fractures involving nasal, orbital, maxillary, zygomatic bones, and more complex Le Fort fractures;  and lower face or mandible fractures

  • Nasal bone fractures are diagnosed through history and careful clinical examination. Routine imaging offers little clinical benefit

Classification of fractures:

  • Mid-face fractures:

Multidetector CT has provided increased detail of the complexity of some mid-facial fractures, leading to innovative classification systems. However, the Le Fort classification remains relevant and widely used in clinical practice .

These fractures are classified into three groups based on the direction of the fracture: horizontal, pyramidal or transverse. The pterygoid plate is involved in all types of Le Fort fractures. This may result in a pterygomaxillary separation. 

Le Fort Type 1 (Guerin fracture):

  • Horizontal fracture. Trans-maxillary horizontal maxillary fracture which separates the teeth from the upper face; the fracture line extends through walls of maxillary antra, through the nasal septum and the pterygoid plates and causes palate-facial separation.

Le Fort Type 2: 

  • Pyramidal fracture. The teeth are at the pyramid base and nasofrontal suture at the apex. A fracture passes through pterygoid plates, posterior and lateral walls of the maxillary sinus. A fracture line passes inferior to the body of zygoma and then crosses the inferior orbital rim, orbital floor and medial wall of orbit, crossing the midline near the nasofrontal suture.

Le Fort Type 3:

  • Transverse fracture causing craniofacial separation. A fracture line passes from the nasofrontal area/suture, maxillo-frontal suture across medial, posterior and lateral orbital walls, the zygomatic arch and through the pterygoid plates.

Le Fort fractures may be associated with other injuries such as dental or alveolar ridge fractures, cerebrospinal fluid leaks (most common with Type 3), and severe epistaxis.

  • Other facial injuries

These include mandibular fractures, paranasal sinus fractures, frontal sinus fractures and nasal fractures.

Computed Tomography (CT)

Computed tomography (CT) (conventional CT or high resolution multidetector CT) is considered the gold standard in facial trauma imaging; it can accurately detect and characterise fractures and their associated complications

  • Conventional or high resolution multidetector computed tomography (CT) is the gold standard for the radiographic evaluation of patients with facial trauma, especially in patients with orbital, maxillofacial and multiple facial injuries

  • CT is superior to other imaging modalities in detecting facial fractures and can accurately define the direction, extent, and displacement of facial fractures as well as assess for associated soft tissue injuries. CT can assist with clinical management and surgical planning

CT +/- OPG

Multidetector CT provides nearly 100% sensitivity in detecting both displaced and nondisplaced fractures, and orthopantomogram (OPG) helps elucidate the relationship of fractures at the mandibular angle to the surrounding teeth and evaluate dental root fractures

  • Orthopantomogram (OPG) was used as a routine and important imaging investigation in patients with mandibular fractures, but is now only recommended as an adjunct imaging test to CT, to help facilitate both diagnosis and surgical planning, when CT alone is insufficient

Plain radiograph + CBCT or OPG

Cone beam computed tomography (CBCT) can adequately recognise mandibular fractures at low radiation dose

  • Cone bean CT (CBCT) has been increasingly used to evaluate isolated mandibular fractures and dentoalveolar trauma, especially in outpatient clinics and ambulatory patients, owing to its low radiation dose, excellent spatial resolution and convenience

  • Plain films are no longer considered a routine part of diagnostic imaging of patients with facial trauma . However, in the absence of conventional CT, plain films are useful in the initial screening for mandibular fractures, but CBCT or OPG should be used to further evaluate and guide optimal management
