Tomography of the sinuses

CBCT (Cone Beam Computed Tomography) of the sinuses is a specialized X-ray imaging procedure that provides detailed 3D images of the sinus anatomy and any existing pathologies. The sinuses are air-filled spaces located within the bones of the skull and face, which include the frontal, maxillary, ethmoid, and sphenoid sinuses.

CBCT of the sinuses offers unparalleled detail for a range of scenarios related to the sinus cavities, which is particularly useful for surgical treatment planning and diagnostics.

Use Cases:

  1. Sinusitis Evaluation: For chronic or recurrent sinusitis cases where standard treatments are ineffective or to identify potential anatomical issues leading to blockage or poor drainage.
  2. Pre-surgical Planning: Before sinus surgery or procedures such as Functional Endoscopic Sinus Surgery (FESS).
  3. Assessment of Sinus Tumors: To determine the size, extent, and precise location of benign or malignant growths within the sinuses.
  4. Evaluation of Traumatic Injuries: To assess fractures or other traumatic injuries to the sinus regions.
  5. Dental Implant Planning: Especially for implants in the upper jaw, where there's a risk of penetrating the maxillary sinuses.
  6. Assessment of Anatomical Variations: Like a deviated septum, concha bullosa, or Haller cells that might impact sinus function or surgical approaches.


  1. High-Resolution 3D Imaging: Offers a detailed view of the sinuses, providing insights not possible with traditional 2D radiographs.
  2. Accurate Measurements: Useful for surgical planning, ensuring procedures are both safe and effective.
  3. Lower Radiation: Compared to traditional CT scans, CBCT exposes the patient to less radiation, making it a safer alternative.
  4. Quicker Scans: The duration of a CBCT scan is shorter than that of a conventional CT scan.


When should it be performed?

CBCT (Cone Beam Computed Tomography) of the sinuses should be performed when detailed 3D visualization of the sinus cavities is crucial for diagnosis, treatment planning, or evaluation. Here are scenarios when a CBCT scan of the sinuses might be recommended:

  1. Chronic or Recurrent Sinusitis: In cases where patients have persistent or recurring sinus infections and standard treatments or medications prove ineffective. CBCT can help identify anatomical abnormalities or obstructions causing these chronic issues.
  2. Pre-surgical Planning: Prior to surgical interventions, such as Functional Endoscopic Sinus Surgery (FESS), to obtain detailed information about the anatomy and potential obstructions.
  3. Dental Implant Considerations: Before dental implant placements in the upper jaw (maxilla) to ensure there's enough bone and to prevent inadvertent penetration into the maxillary sinuses.
  4. Sinus Tumors or Growths: To evaluate the presence, size, location, and extent of benign or malignant growths or masses within the sinus cavities.
  5. Traumatic Injuries: Following facial trauma to assess any fractures, injuries, or obstructions in the sinus regions.
  6. Evaluation of Anatomical Variations: In cases where anomalies such as a deviated septum, concha bullosa, Haller cells, or other structural variations might be causing sinus issues or need to be accounted for in surgical planning.
  7. Bone Grafting and Sinus Lift Procedures: Before procedures intended to increase the bone volume in the upper jaw, especially when it's close to the sinuses.
  8. Unexplained Facial Pain: When patients present with facial pain or pressure not attributed to other known causes, a CBCT scan can help in diagnosing potential sinus-related issues.
  9. Post-surgical Evaluation: After surgical interventions involving the sinus region to assess the outcome, ensure proper healing, and identify potential complications.

How does the procedure look like?

The procedure is non-invasive and painless:

  • The patient is asked to remove anything that may interfere with the imaging, including metal objects, such as jewelry, eyeglasses or hearing aids.
  • The patient either sits or stands in the CBCT machine.
  • The patient must remain still during the scan to ensure image clarity. As the scanner rotates around the patient's head, it captures multiple images from various angles, which are then reconstructed into a 3D model.

Do I need to prepare for the procedure?
No special preparation is required. However, you'll be asked to remove any metal objects like glasses, earrings, and necklaces. If you have dental appliances or dentures, you might need to remove them as well.

When will I get my results?
Shortly after each examination we will send the results via email to you and/or to your doctor's email address listed on the referral. Additionally we can provide the results on a CD or Pendrive.

Is it safe to have a Computed Tomography during pregnancy?
Always inform your dentist or technician if you're pregnant or suspect you might be. While the radiation dose is low, it's a general practice to avoid any unnecessary exposure to it during pregnancy.

Is there an age limit for Computed Tomography?

No, there isn't an age-specific limit. Computed Tomography can be beneficial for both children and adults, depending on the medical concern.

Always consult with your doctor for specific details and any further queries related to Tomography of the sinuses or any other medical procedure.

Duration of the examination

until 30 second



Radiation intensity


3-20 hours flight
The radiation dose during the examination is minimal (20-150 µSv). To put it in perspective, it is equivalent to a 3-20 hours flight.
