Abstract
The frequency of midface and frontobasal fractures has increased over the past 40 years despite the improvement and stringent regulation implemented on modern safety equipment (belts, helmets…). This observation might be correlated with the progress of radiodiagnosis tools. Literature was reviewed according to Prisma guidelines. We searched for reviewed articles, published between January 2000 and December 2017, through Medline (Pubmed) online databases and ScienceDirect, using the following MeSH Keywords: "Le Fort classification", "Le Fort fracture", "Frontobasal fracture", "skull base fracture", "Midface Fractures". Among 652 patients with frontobasal fractures, 125 (19.1%) were associated with a Le Fort fracture. 59 (9%) were associated with Le Fort III fracture, 51 (7.8%) with Le Fort II fracture and 15 (2.3%) with Le Fort I fracture. When frontobasal fractures were associated with midfacial fractures, we found 18 cerebrospinal fluid leaks (11.8 %) and 19 cases of meningitis (12.5 %). When only the frontobasal area was involved, there were 6 cerebrospinal fluid leaks (4.3 %) and 6 meningitis (4.3 %). Our results highlight a regular association between Le Fort fractures and frontobasal fractures for stages II and stage III of Le Fort fractures and also found a higher rate of neuro-septic complication. Further research shall investigate treatment and monitoring recommendations fitting modern epidemiology of craniofacial traumatology.

Abstract
Study Design This article was a technical note. Objective To demonstrate the utilization of virtual surgical planning for surgical splint (VSPSS) fabrication. The VSPSS was used as an intraoperative assisting and guiding tool for reduction and/or fixation of treatment of comminuted maxillomandibular fractures. Methods The presented technical note showed the fabrication process that began with data acquisition and presurgical planning using virtual surgical planning (VSP). The VSPSS was designed and fabricated after the fractures were reduced digitally in VSP. In the operating room, the VSPSS was seated to guide reduction and/or allow satisfactory fixation in three different situations. Results Postoperative radiographs showed an acceptable reduction of the fractures. All patients had stable and repeatable occlusion postoperatively. Conclusions The VSPSS is a feasible tool for surgeons to assist in the comminuted maxillomandibular fracture management, decrease operating time, and improve fracture stability.

Abstract
Treatment of craniomaxillofacial (CMF) trauma in dogs requires a thorough understanding of the CMF skeletal structures involved. The human medical literature has several examples of CMF trauma and fracture classification, including the classically described Le Fort fractures. The recent classification schemes require large studies using computed tomography (CT). In the veterinary medical literature, such studies are lacking. The aims of part II of this retrospective study were to use a large number of CT studies of dogs evaluated for CMF trauma to determine whether specific fracture locations in the CMF region occur concurrently, and whether trauma etiology influences fracture morphology. This information may then be used to form a fracture classification scheme in the future. The medical records and CT studies of 165 dogs over a 10-year period were evaluated. The skeletal location of CMF fractures as well as the severity of displacement and fragmentation of each fracture was recorded. Dogs' demographic data and trauma etiology were also recorded. Fractured portions of the mandible tended to occur with fractures of adjacent bones, with the major exception of symphyseal separation, which occurred simultaneously with fractures of the cribriform plate. Fractures of the maxillary bone were accompanied by many concurrent fractures affecting the majority of the midface, skull base, and cranial vault. When the zygomatic bone was fractured, the other bones comprising the orbit also tended to fracture. Fractures of the relatively superficially located frontal and nasal bones were often accompanied by fractures of the skull base. Fracture etiology influenced fracture morphology such that vehicular trauma resulted in a relatively higher number of severely displaced and comminuted fractures than did other trauma etiologies. This study provides examples of fractures that, when found, should prompt veterinarians to look for additional injuries in specific locations. In addition, it further highlights the need for thorough CT evaluation of the entire CMF region, even when clinically apparent fractures appear relatively superficial.

Abstract
In patients with facial trauma, multidetector computed tomography is the first-choice imaging test because it can detect and characterize even small fractures and their associated complications quickly and accurately. It has helped clinical management and surgical planning, so radiologists must communicate their findings to surgeons effectively. In Le Fort fractures, there is a breach between the pterygoid plates and the posterior maxilla. These fractures are classified in three basic patterns that can be combined and associated with various complications. Conceptualized when low-speed trauma was predominant, the Le Fort classification system has become less relevant giving more importance on maxillary occlusion-bearing segments. The classification of naso-orbito-ethmoid depends on the extent of injury to the attachment of the medial canthal tendon, with possible complications like nasofrontal duct disruption. Displaced fractures of the zygomaticomaxillary complex often widen the angle of the lateral orbital wall, resulting in increased orbital volume and sometimes in enophthalmos. Severe comminution or angulation can lead to wide surgical exposure. In orbital fractures, entrapment of the inferior rectus muscles can lead to diplopia, so it is important to assess its positioning and morphology. Orbital fractures can also result in injuries to the globe or infraorbital nerve. Frontal sinus fractures that extend through the posterior sinus wall can create a communication with the anterior cranial fossa resulting in leakage of cerebrospinal fluid, intracranial bleeding. It is essential to categorize fracture patterns and highlight features that may affect fracture management in radiology reports of facial trauma.

Abstract
Trauma to the facial area accounts for a significant number of admissions to the emergency department. Diagnostic imaging is almost always required, and is critical in determining patient management. Multi‐detector computed tomography (MDCT) appears consistently in the literature as the gold‐standard imaging modality for facial bones, but results in a high radiation dose to the patient. This makes the application and advancement of dose reduction and dose optimisation methods vital. This narrative review presents a critical analysis of the literature concerning diagnostic imaging of facial bone trauma, with an emphasis on dose reduction methods for MDCT. Databases including Pubmed, Medline, Web of Science and Scopus were used to investigate this topic, with the key words: facial bone trauma, computed tomography (CT) imaging and dose reduction. Exclusion criteria included studies on nasal bone fracturing, dental imaging, elective surgeries and paediatric imaging. The literature shows overwhelming support for MDCT, given its accuracy, efficiency and ease of operation. Noise reducing reconstruction algorithms show promise as a successful method of dose reduction in facial bone imaging. Investigations of more innovative techniques also appear within the literature, including diagnostic cone‐beam CT (CBCT), intraoperative CBCT and dual‐source CT (DSCT), but further research is required to confirm their clinical value.

Abstract
This article aims to analyze the changing Le Fort fracture patterns using computed tomography (CT) scans with three-dimensional (3D) reconstruction. A prospective observational study was conducted on 60 patients with midface trauma, who had reported to MS Ramaiah Group of Hospitals, Bangalore, between January 2015 and October 2016. CT scans using 1.6 mm axial, sagittal, coronal sections were taken and their 3D reconstruction was made. The images were studied and compared with the standard Le Fort lines. The deviations from the classical Le Fort lines were analyzed and recorded. A note was also made of any additional fixation that was required for these deviations. Descriptive analysis was done and the results expressed in numbers and percentages. Study revealed that the most common cause for the midface fractures was found to be road traffic accidents (81.7%) with a male preponderance (88.3%) and peak incidence in 21 to 30 years of age (40%). Among the 60 patients, 18 (30%) patients had fracture patterns similar to the ideal Le Fort lines, 4 (6.6%) had a combination of Le Fort patterns, and 38 (66.3%) patients had deviations seen from the ideal Le Fort lines. Four types of deviations were recorded, namely, D1(60%), D2(5.4%), D3(10.9%), and D4(23.6%). It was observed that D1 and D3 required additional fixation. Majority of the cases presented as a deviation from ideal Le Fort fractures. CT was a valuable tool in the assessment of these fracture patterns. Deviations, if any, could be better analyzed using the 3D reconstruction images. Proper diagnosis and detection of these deviations make the planning for fixation easier. Repetition of these deviations could propose a newer or modified classification system for Le Fort fractures.
