# Comparative Study of Computerized Tomography Imaging of Facial Trauma Using 2D and 3D Reconstruction Scans

## TL;DR

This study compares 2D and 3D CT scans for detecting facial bone fractures and finds that 3D scans provide clearer images for treatment planning.

## Contribution

The study empirically demonstrates the superior diagnostic value of 3DCT over 2DCT in facial trauma assessment.

## Key findings

- 3DCT better delineated maxilla, mandibular, and orbital fractures compared to 2DCT.
- Zygomatic arch fractures showed similar detection rates in both 2D and 3D scans.
- 3DCT provides a real-time view of fractures, aiding in surgical or conservative treatment decisions.

## Abstract

Background

The article intends to compare the efficacy of detecting fractures of facial bones in terms of the number of fractures detected, single or multiple involvement, displaced or undisplaced, segmental involvement, and comminuted or non-comminuted using 2D computerized tomography (CT) versus 3DCT for planning optimum treatment.

Methodology

One hundred patients with suspected facial bone fractures sustained either by assault, road traffic accident, or self-fall on arrival to casualty were examined clinically. Subsequently, palpation was done to detect facial bone fractures. On suspicion, they were subjected to a CT scan of the face in both coronal and axial views. The results were interpreted in the form of bones involved and detection of fractures of the same on both 2D and 3D scans. The acquired images of fractures obtained by 2D scan were reconstructed using software to obtain virtual images of the same by 3D scan to help further delineate which fractures or combination of them are better appreciated on both scans.

Result

Out of 100 patients, 52 had maxilla fractures, which were better delineated by 3D scans. The detection of zygomatic arch fractures was almost equal on both scans. Mandibular and orbital fractures were better delineated by 3D scans.

Conclusion

To conclude, we believe that in maxillofacial trauma, 3DCT provides better information than 2DCT, especially with regard to the delineation of fractures and the involvement of single or multiple bones, as it gives a real-time picture of the same. This helps in planning the management of patients, whether surgical intervention is required or can be managed conservatively.
