3D CT FACE AND CRANIUM

3D CT Face and Cranium Overview

Introduction 

3D CT (Computed Tomography) of the face and cranium is an advanced diagnostic imaging test that captures high-resolution, three-dimensional images of the facial skeleton, skull, and surrounding soft tissues. It offers anatomical details invaluable in a trauma workup, evaluation of congenital anomalies, infections, tumours, and pre-surgical imaging. 

What is a 3D CT Face and Cranium? 

3D CT imaging employs X-ray technology and sophisticated computers to produce volumetric reconstructions of the facial skeleton and skull. This offers the clinician a thorough and spatial appreciation of the bony structures and abnormalities that may be present. The images undergo rotation and can be viewed from various angles for extensive analysis. 

Parameters Considered

• Bone continuity and continuity  
• Fracture displacement or comminution  
• Erosive or mass lesions 
• Structures of the sinuses and the orbital walls 
• Symmetry of the cranial vault and base 

Reasons for the Test

• Assess maxillofacial trauma. 
• Diagnose craniosynostosis and other skull malformations. 
• Determine the extent of a tumour for surgical excision. 
• Evaluate complex facial pain and sinus pathology. 
• Provide guidance to implant or prosthesis placement. 

When and Who Needs a 3D CT Face and Cranium? 

Indications 

• Facial trauma or fractures  
• Presurgical planning for maxillofacial or neurosurgery. 
• Tumours or lesions in the facial and cranial bones. 
• Congenital skull abnormalities (e.g., craniosynostosis). 
• Orbital fractures or malformations. 

Patient Demography 

• Trauma patients 
• Paediatric patients with craniofacial deformities. 
• Patients undergoing cosmetic or reconstructive surgery. 
• Oncology patients with suspected malignancy of the skull or facial bones. 

Benefits of Taking the Test

• Enables accurate diagnosis using advanced 3D imaging technology.  
• Quick, non-invasive.  
• Assists in the surgical procedure diagnosis and helps navigate the procedure.  
• Aids in identifying minute fractures and lesions which are hard to detect.  

Conditions Diagnosed

• Fractures of the facial bones.  
• Deformities of the skull.  
• Tumours of the skull base and facial bones.  
• Bony chronic sinusitis.  
• Fractures or infections of the orbit. 

Preparation

• Wear clothes that are loose fitting.  
• Remove jewellery, hearing aids, and glasses.  
• Notify hospital staff about medical history and any implants.  
• Arrive beforehand to decide for consent and setup.  

Pre-requisites 

• Appointment with a healthcare professional.  
• Previous images and reports (if available).  

Best Time to Take the Scan 

• Anytime, dependent on the clinical prioritization.  
• Early for same-day reporting.  

Eligibility 

• Most individuals are eligible.  
• Must exercise caution when prescribing to pregnant women.  

Procedure 

• The face and head are aligned for best imaging.  
• The scan takes under 10 minutes.  
• If required, an IV line is established for contrast injections.  
• A 3D reconstruction is done after the scan.  

Caution: 

• Must not move during the procedure.  
• Must tell the radiologist if pregnant or allergic to contrast.
