Facial Bones

A facial bones CT scan is a non-invasive test that provides detailed 3D images of the facial skeleton to detect fractures, sinus issues, or abnormalities for accurate diagnosis and surgical planning.

What Is a Facial Bone CT Scan?

A facial bone CT scan is an advanced imaging procedure used to obtain detailed views of the facial skeleton, including the bones of the face and facial skeletal structure. This scan captures thin slices of the face and creates 3D reconstructions to assess bone integrity, detect trauma, or evaluate abnormal growths. The facial bone CT scan provides a more accurate assessment than traditional X-rays, making it a preferred tool for diagnosing complex facial conditions.

When Is a Facial Bone CT Scan Needed?

Doctors recommend a facial bone CT scan when patients suffer from facial trauma, suspected fractures, congenital bone anomalies, sinus infections affecting bone structure, or pre-surgical planning. For example, if someone presents with a fractured cheekbone, a CT scan can detect subtle or displaced facial bone fractures that are not visible in an X-ray of the facial bones.

Understanding Facial Bone Anatomy

The facial bone anatomy comprises structures such as the maxilla, zygomatic bones (also known as cheekbones), nasal bones, and mandible. These bones of the face form the facial skeleton, which supports facial muscles, protects sensory organs, and defines our appearance. The viscerocranium bones the front part of the skull play a major role in facial shape and function.

Facial Bones Captured in a CT Scan

A CT scan of the face typically includes:

• Bones of the cheek (zygomatic bones)
  
• Nasal bones
  
• Maxilla (upper jaw)
  
• Mandible (lower jaw)
  
• Orbits (eye sockets)
  
• Temporal bones
  

It evaluates both hard tissues (bone) and adjacent soft tissue structures. This is especially useful in diagnosing abnormalities in the bones in the face, detecting any asymmetry, or mapping the bones on the face before cosmetic or reconstructive procedures.

CT Scan vs. X-Ray for Facial Bones

While X-rays of facial bones are quick and accessible, they provide only 2D images and may miss subtle fractures. A CT scan of facial bones delivers highly detailed 3D views, making it superior for diagnosing:

• Bone on face fractures
  
• Internal facial bone structure disruptions
  
• Deep-seated sinus or orbital injuries
  

Thus, CT is often used in emergency rooms and surgical planning due to its accuracy.

How to Prepare for a Facial Bone CT Scan

Preparing for a facial bone CT scan is simple:

• Remove any metal jewellery or hairpins near the head and face
  
• Inform your technician if you're pregnant or have implants
  
• Stay still during the scan for accurate imaging
  

No fasting or special preparation is usually required unless contrast dye is used.

Common Facial Injuries Detected by CT Scans

CT scans can reveal:

• Facial fractures (e.g., fractured cheekbones)
  
• Sinus wall disruptions
  
• Orbital trauma
  
• Jaw fractures or dislocations
  
• Post-surgical healing assessment
  

In trauma cases, detailed scans of the facial bones and surrounding tissues help determine the severity and guide treatment.

Risks and Safety of Facial CT Scans

Facial CT scans are generally safe, but like all radiological tests, they involve low levels of ionising radiation. The benefits outweigh the risks, especially when precise visualisation of the facial skeletal system is needed. Pregnant women should inform their doctor beforehand.

Cost and Availability of Facial Bone CT Scans in the UK

The cost of a facial CT scan in the UK typically ranges between £250 and £500, depending on the clinic and whether contrast is used. Many private imaging centres across London, Manchester, and other cities offer same-day or next-day appointments. NHS referrals may be free but involve longer wait times.

The Procedure: What to Expect

• You will lie on a motorised table that moves into the CT scanner.
  
• The scan takes 5–10 minutes.
  
• The machine rotates around your head, capturing images of the facial bones, including the facial bones, bones of the face and jaw.
  

A radiologist will analyse the results to identify any abnormalities in your facial skeleton or facial bone anatomy.

Interpreting Facial Bone CT Scan Results

A radiologist reviews the images for:

• Bone alignment
  
• Fractures or deformities
  
• Signs of infection or tumour
  
• Congenital anomalies
  

You will receive a report that your GP or specialist will explain, detailing the state of your bones on the face and potential issues requiring treatment.
