AIMS AND OBJECTIVES:

To determine diagnostic accuracy of Multi Planar Reconstruction (MPR) and 3D Reconstruction in Maxillo–facial

trauma.

MATERIALS AND METHODS:

We conducted a prospective study of 235 patients with history of maxillofacial trauma referred to the Department of radio diagnosis, who

underwent plain CT scans with facial bones protocol during January 2015 to June 2016. e imaging was performed using GE Bright Speed

Elite 16 Slice CT Scanner. Post processing multi planar reconstruction in thin bone window and 3D CT reconstruction were obtained.

RESULTS:

Out of 235 patients with maxillofacial trauma 160 are males and 75 are females. e 21–30 years age group has highest percentage of

maxillofacial trauma. It was found that nasal bone (67.2%) is most common to be fractured followed by zygomatic bone (51%), maxillary bone

(43.4%), mandibular bone (28.9%) and pterygoid plate (16.1%). All maxillary bone and pterygoid plate fractures are detected in thin bone

MPR. While 89.8% of nasal bone fractures and 91.6% of zygomatic bone fractures are detected by MPR. 3D reconstruction was able to detect

only 75.9% of nasal bone fractures, 75% of zygomatic bone fractures, 73.5% of maxillary bone fractures, 86.7% of mandibular fractures and

26.3% of pterygoid plate fractures. MPR technique was found to be more detective for fractures when compared to 3D reconstruction.

CONCLUSION:

MDCT with MPR technique allowed better visualisation of maxillofacial fractures. MDCT is the preferred modality for diagnosing maxillofacial

fractures due to its higher sensitivity and specificity and plays a useful role in pre–operative planning and treat the patient in golden

hour.
