Computed Tomography (CT)

Medical imaging using X-rays.

CT Of The Facial Bones

 A CT of the Facial Bones is an exam that takes very thin slice (2-3.5mm) images of the facial bone structure, including the jaw, nose, eye sockets and cheek bones. These images are helpful in the diagnosis of facial trauma and malformations.

  1. Facial Trauma: After a traumatic injury to the face, such as fractures from falls, accidents, or assaults, a CT scan can provide detailed images to assess the extent and location of fractures in the facial bones.

  2. Assessment of Facial Fractures: CT is particularly useful for evaluating fractures in delicate facial structures, including the nose, orbits (eye sockets), jaw, and cheekbones.

  3. Sinus Problems: CT scans of the facial bones can help identify and evaluate issues in the paranasal sinuses, such as sinusitis, polyps, or other sinus-related conditions.

  4. Evaluation of Dental Issues: CT scans can be used to assess dental problems, including impacted teeth, dental infections, and abnormalities in the jaw.

  5. Temporomandibular Joint (TMJ) Disorders: For individuals experiencing symptoms related to TMJ disorders, such as jaw pain, clicking sounds, or difficulty in jaw movement.

  6. Pre-surgical Planning: Before facial reconstructive or orthognathic surgeries, a CT scan may be performed to help surgeons plan the procedure by providing detailed images of the facial bones and structures.

  7. Evaluation of Facial Masses or Tumors: CT scans can help detect and assess the characteristics of facial masses or tumors, aiding in diagnosis and treatment planning.

  8. Assessment of Nasal Obstruction: To identify the cause of nasal obstruction, such as deviated septum, nasal polyps, or other structural abnormalities.

  9. Evaluation of Congenital Abnormalities: CT scans can be used to evaluate congenital abnormalities or malformations of the facial bones, providing valuable information for diagnosis and treatment planning.

  10. Facial Infections: In cases of suspected facial infections or abscesses, a CT scan can provide detailed images to assess the extent of infection and guide treatment.
