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

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.

The Added Value of Multislice Computerized Tomography in Evaluation of Maxillofacial Fractures.

Background: As Regard fracture morphology, The maxillofacial fractures are often complex, so the imaging findings should be familiar to the clinicians. To diagnose maxillofacial fractures, several radiographic approaches have been utilized. Recently, Multidetector computed tomography (MDCT) with three-dimensional (3D) and multiplanar reformation (MPR) become basic in fractures evaluation because of its higher sensitivity.Objective: The study purpose to 1- To study the number, extent, and degree of fractures displacement through the utilization of axial, coronal & 3D reformatted images. 2. Study the value of axial, coronal & 3D reformatted images in fractures recognition.Methodology: This study has been done through the collection of data from papers which has been searched upon PubMed from 2001 till 2017, the search is done including only the papers written in English language and collected data including maxillofacial region anatomy, a hint about the CT physics and injury presentation.Summary:The fracture is classified into orbital, facial and mandibular fractures and the facial fractures are sub-classified into upper, mid and lower face fractures. In complex midface fractured patients, it easy detects frontal and maxillary bones fractures and their displacement. In comparison with X-ray, Mandibular CT imaging, in particular, MDCT, It is highly sensitive in mandibular fracture detection, and provide excellent detail in detecting mandibular condyle fractures. and The coronal reconstruction has a superior role in the orbital and maxillary fractures detection.Conclusion: MDCT with (3D)and (MPR) images become a standard piece of fractures evaluation due to sensitivity of this imaging system for fracture.

The role of multi detector computerized tomography in evaluation of maxillofacial fractures

ObjectiveThe purpose of our study was to assess the role of multi-detector CT in the evaluation of maxillofacial fractures. Subjects and methodsThe study included 30 patients complaining from facial trauma with suspected facial fractures referred from the emergency unit of the El-Minia University Hospital. All patients subjected to non contrast MDCT in axial cuts and images are transferred to workstation then they underwent coronal, sagittal reconstructed images and 3-D volume rendering that are of benefit in final diagnosis. ResultsA total of 30 patients were included (their mean age 26years). It was found that the nasal bone is most common to be fractured (found in 19 cases), followed by maxillary bone (17 cases), zygomatic bone (10 cases), mandibular bone (8 cases) and the pterygoid plates are least frequent to be fractured (6 cases). Also, concerning the complex facial fractures; the orbital wall fractures are the most frequent (found in 22 cases), followed by zygomatico-maxillary complex fractures (8 cases), the naso-orbito-ethmoid fractures (6 cases), and lastly comes the Le Forte fractures (found in 4 cases). ConclusionThe use of MDCT is mandatory for the accurate classification of maxillo-facial fractures and so the management decision.

Applications of cone‐beam computed tomography in fractures of the maxillofacial complex

Imaging plays an essential role in the evaluation of maxillofacial fractures both pre- and postoperatively. Several studies support the use of conventional two-dimensional imaging for traumas involving mainly the mandible, but for more complex situations advanced imaging modalities such as computed tomography (CT) and magnetic resonance imaging have higher indication. Nowadays, besides CT, cone-beam computed tomography (CBCT) has appeared as a reasonable and reliable alternative considering radiation dosage, image quality and comfort for the patient. The purpose of this study was to review the fracture patterns involving the maxillofacial complex, provide a technical and practical comparison between CT and CBCT, and finally present the potential applications of CBCT illustrated with clinical examples.

Abnormal linear density. A useful x-ray sign in the evaluation of maxillofacial fractures.

ACCURATE x-ray assessment is invaluable in planning the treatment of maxillofacial fractures. The contemplated surgical approach is influenced by the preoperative physical examination and x-ray film findings. The task of making an accurate x-ray diagnosis prior to surgery is straightforward when fracture lines are visible, large bony fragments are displaced, suture lines are open, and sinus cavities are opaque. The situation occasionally arises where the physical findings and the x-ray film findings are equivocal or in disagreement. When this problem occurs, small points are sometimes the deciding factors. In the detailed review of over 300 cases of facial fractures, an interesting radiographic phenomenon has been observed. In the absence of gross radiographic deformity, a fragment of displaced bone can sometimes be seen on edge, producing an abnormal linear density, easily visible on the film. The shadow is produced by a displaced, fractured segment which lies tangential to the x-ray beam,
