“…15,16 Pain, trismus, difficulty in chewing, malocclusion, swelling and fractures are the common presentations of the mandibular trauma. 16 Any asymmetry in the occlusion is highly suggestive of mandibular fracture. 17 The incidence of cervical spine injuries with facial trauma accounts for 1 to 10% according to various studies that could be asymptomatic at the time of initial presentation.…”

“…[18][19][20] The sensitivity of multidetector computed tomography (MDCT) to detect mandibular fracture are 100% whereas orthopanoramic radiograph and conventional x-rays had only 86% sensitivity. 16 Multidetector computed tomography (MDCT) is the investigation of choice and is the most appropriate imaging modality to evaluate patients of maxillofacial trauma. While evaluating orbital fractures, it is necessary to assess the optic nerve, the globe and the intraorbital soft tissues including the extraocular muscles.…”

Introduction: Maxillofacial injuries are one of the most frequently encountered entities accounting for a large proportion of patients in emergency department. Present study was performed to assess the role of multidetector computed tomography (MDCT) in patients of maxillofacial trauma and to describe the spectrum of various patterns of injuries in maxillofacial region in this part of Nepal. Methods: The study was carried out on a prospective basis over a period of one year. All the patients referred for evaluation of maxillofacial trauma were included in the study. MDCT was done in patients of maxillofacial injury and the data was recorded and analyzed. Volumetric MDCT scan of the maxillofacial region was performed in axial plane with multiplanar reconstruction in coronal and sagittal planes were obtained wherever required. Results: Out of 60 patients of maxillofacial trauma 42 (70%) were males and 18 (30%) were females and age ranges from 12 to 70 years. The 11?30 years age group has the highest percentage (55%) of maxillofacial trauma, followed by 31?40 (20%). The common cause of injuries in our study was road traffic accidents (58.33%), fall from height (20%), physical assault (16.66%) and sport injuries (5%). Out of 60 patients there was total of 115 fractures. The frequency and types of fracture was as follows: orbital floor fracture in 21 (35%), maxillary sinus wall fracture in 18 (30%), nasal bone fracture in 17 (28.33%), jaw fracture in 15 (25%), zygomatic bone fracture in 13 (21.66%), orbital wall fracture in 11 (18.33%), naso?ethmoidal fractures in 9 (15%), frontal sinus fracture in 7 (11.66%), Lefort fracture in 1 (1.66%) and others 3 (5%). The highest percentage of fracture was of orbital floor (35%) followed by fracture of wall of maxillary sinus (30%) and nasal bone fracture (28.33%). Three cases had simultaneous injury of the globe and cervical spine; they underwent computed tomography/magnetic resonance imaging for the assessment of spine. Conclusion: Injuries to maxillofacial region is one of the most common emergency requiring accurate and early diagnosis for preventing unnecessary investigations and proper management. MDCT has high sensitivity and specificity and has high accuracy for detection of fracture. DOI: http://dx.doi.org/10.3126/ajms.v5i4.9561 Asian Journal of Medical Sciences 2014 Vol.5(4); 39-43

“…4 It is an important imaging modality in diagnosing the mandibular fractures. 5,6 The spatial resolution of MDCT is excellent, which enables Multiplanar Reformations (MPR) and 3-D reconstructions allowing better diagnostic accuracy and surgical planning and provides excellent information about fracture comminution and displacement. 7 Involvement multiple planes in complex fractures can be assessed which aids in the surgical management.…”

Background & Objectives:The maxillofacial r egion, a complex anatomical structure, can be evaluated by conventional (plain) films, Tomography, Multidetector Computed Tomography, Three-Dimensional Computed Tomography, Orthopantomogram and Magnetic Resonance Imaging. The study was conducted with objective of describing various forms of maxillofacial injuries, imaging features of different types of maxillofacial fractures and the advantage of using Three-Dimensional Computed Tomography reconstructed image. Materials & Methods: A hospital based cross-sectional study was conducted among 50 patients during April 2014 to September 2016 using Toshiba Aquilion Prime 160 slice Multi Detector Computed Tomography scanner. Results: The maxillofacial fractures were significantly higher in male population (88%) than female population (12 %). Road traffic accidents were the most common cause of injury others being physical assault and fall from height. It was most common in 31-40 years (26%) and 21-30 (24%) years age group. Maxillary sinus was the commonest fracture (36%) followed by nasal bone and zygomatic bone (30%), mandible and orbital bones (28%). Soft tissue swelling was the commonest associated finding. Three dimensional images (3 D) compared to the axial scans missed some fractures. However, the extension of the complex fracture lines and degree of displacement were more accurately assessed. Complex fractures found were Le fort (6%) and naso-orbito-ethmoid (4%) fractures. Conclusion: The proper evaluation of complex anatomy of the facial bones requires Multidetector Computed Tomography which offers excellent spatial resolution enabling multiplanar reformations and three dimensional reconstructions for enhanced diagnostic accuracy and surgical planning.
