What is a CBCT Sinus Scan?
Cone Beam Computed Tomography (CBCT) is a specialist X-ray technique that produces detailed three-dimensional images of the nasal cavity, paranasal sinuses, and surrounding bony anatomy. Unlike a standard hospital CT, CBCT delivers a lower radiation dose while achieving higher resolution of the bony structures most relevant to ENT diagnosis and surgical planning.
At 3Beam, all sinus CBCT scans are performed on the Planmeca ProMax, with a 20 × 17 cm field of view covering the full sinonasal anatomy in a single acquisition, and reported by UK consultant radiologists, ensuring your ENT specialist receives a clinically actionable report, not just raw images.
Conditions We Image
Our CBCT sinus scans are used by ENT surgeons, rhinologists, and maxillofacial surgeons to assess a wide range of conditions, including:
- Chronic rhinosinusitis (CRS)
- Acute sinusitis unresponsive to treatment
- Nasal polyps
- Deviated nasal septum
- Concha bullosa and other anatomical variants
- Mucosal thickening and bony erosion
- Suspected fungal sinusitis
- Sinonasal tumour workup (initial assessment)
- Pre-operative planning for FESS
- Pre-operative planning for balloon sinuplasty
- Post-surgical follow-up and monitoring
- Skull base and orbital assessment
Why Choose CBCT Over Conventional CT for Sinus Imaging?
Higher resolution of bony anatomy
CBCT produces exceptional detail of the ethmoid air cells, ostiomeatal complex, and skull base — the structures most critical for FESS planning — with less scatter and artefact than conventional CT.
Lower radiation dose
CBCT exposes patients to significantly less radiation than standard multislice CT, making it appropriate for serial imaging in patients with chronic conditions requiring monitoring over time.
Speed and patient comfort
The scan itself takes under 60 seconds, reducing motion artefact and making the process more comfortable for patients who are unwell or have difficulty remaining still.
No hospital visit required
3Beam is an independent imaging centre. Patients attend our Harley Street clinic directly — no A&E, no hospital radiology department, no unnecessary wait.
Rapid consultant reporting
Our reports are produced by experienced UK consultant Head & Neck radiologist (Dr Mandy Williams) and returned to your team within 1 week. DICOM images are available for review on the same day.
