THE ROLE OF MULTI DETECTOR COMPUTERIZED TOMOGRAPHY (MDCT) IN EVALUATION OF MAXILLOFACIAL FRACTURES.

Abstract

Objective: The purpose of our study was to assess the role of Multidetector Computerized tomography in the evaluation of maxillofacial fractures and to describe the frequency and types of fractures that underwent CT scans. Subjects And Methods: The study included 50 patients suspected of facial trauma referred from the emergency unit from PESIMSR ,Kuppam. All patients were subjected to non contrast MDCT in axial cuts and images are transferred to workstation then coronal and sagittal reconstruction obtained. Results: There were 37 male and 13 female patients. The maximum number of patients fall into 21-40 years followed by 41 to 60 years .50 patients had total 170 fractures. It was found that the maxillary sinus is the most common to be fractured (found in 24 cases) followed by nasal bone (18) , zygomatic arch (17), mandible (13) ,greater wing of sphenoid (9), sphenoid sinus (8), frontal sinus (7) ,pterygoid plates (7), bony nasal septum (6) ,ethmoid sinus (3).Among complex facial fractures orbital fractures are the most frequent (found in 47 cases), followed by zygomatico-maxillary junction fractures (4) ,Tripod fractures( 4) , and Naso-orbito-ethmoid region fractures (3). Conclusion: Maxillofacial trauma is one of the most common emergency requiring accurate and early diagnosis. MDCT is useful diagnostic tool for the identication and classication of maxillofacial region fractures and aiding in surgical planning.
