Reconstructive surgery for complex midface trauma using titanium miniplates: Le Fort I fracture of the maxilla, zygomatico-maxillary complex fracture and nasomaxillary complex fracture, resulting from a motor vehicle accident.maxillofacial injuries resulting from trauma can be a challenge to the Maxillo-Facial Surgeon. Frequent causes of these injuries are attributed to automobile accidents, physical altercations, gunshot wounds, home accidents, athletic injuries, work injuries and other injuries. Motor vehicle accidents tend to be the primary cause of most midface fractures and lacerations due to the face hitting the dashboard, windshield and steering wheel or the back of the front seat for passengers in the rear. Seatbelts have been shown to drastically reduce the incidence and severity of these injuries. In the united states seatbelt laws have been enacted in several states thus markedly impacting on the reduction of such trauma. In the philippines rare is the individual who wears seat belts. Metro city traffic, however, has played a major role in reducing daytime MVA related trauma, as usually there is insufficient speed in traffic areas to cause severe impact damage, the same however cannot be said for night driving, or for driving outside of the city proper where it is not uncommon for drivers to zip into the lane of on-coming traffic in order to overtake the car in front ... often at high speeds. Thus, the potential for severe maxillofacial injuries and other trauma related injuries increases in these circumstances. It is however unfortunate that outside of Metro Manila or other major cities there is no ready access to trauma or tertiary care centers, thus these injuries can be catastrophic if not addressed adequately. With the exception of Le Fort II and III craniofacial fractures, most maxillofacial injuries are not life threatening by themselves, and therefore treatment can be delayed until more serious cerebral or visceral, potentially life threatening injuries are addressed first. Our patient was involved in an MVA in Zambales, seen and stabilized in a provincial primary care center initially, then referred to a provincial secondary care center for further stabilization before his transfer to Manila and then ultimately to our Maxillo-Facial Unit. There was a two week-plus delay in the definitive management because of this. As a result of the delay, fibrous tissue and bone callus formation occurred between the various fracture lines, thus once definitive fracture management was attempted, it took on a more reconstructive nature. Hospital based Oral and Maxillo-Facial Surgeons are uniquely trained to manage all aspects of the maxillo-facial trauma, and their dental background uniquely qualifies them in functional restoration of lower and midface fractures where occlusion plays a most important role. Likewise, their training in clinical medicine which is usually integrated into their residency education (12 months or more) puts them in a unique position to comfortably manage the basic medical needs of these patients. In instances where trauma may affect other regions of the body, an inter-multi-disciplinary approach may be taken or consults called for. In this instance, an opthalmology consult was important. In fresh trauma, often seen in major trauma centers (i.e. overseas), a "Trauma Team" is on standby 24 hours a day, and is prepared to assess and manage trauma patients almost immediately upon their arrival in the ER. The trauma team is usually composed of a Trauma Surgeon who is a general surgeon with subspecialty training in traumatology who assesses and manages the visceral injuries, an Orthopedic Surgeon who manages fractures of the extremities, a Neurosurgeon for cerebral injuries and an Oral and Maxillo-Facial Surgeon for facial injuries. In some institutions, facial trauma call is alternated between the "three major head and neck specialty services", namely Oral and Maxillo-facial Surgery, otolaryngology-Head & neck Surgery and Plastic & Reconstructive Surgery.

2/10. Selective laser sintering: application of a rapid prototyping method in craniomaxillofacial reconstructive surgery.Advances in technology have benefited the medical world in many ways and a new generation of computed tomography (CT) scanners and three-dimensional (3-D) model making rapid prototyping systems (RPS) have taken craniofacial surgical planning and management to new heights. With the development of new rapid prototyping systems and the improvements in CT scan technology, such as the helical scanner, biomedical modelling has improved considerably and accurate 3-D models can now be fabricated to allow surgeons to visualise and physically handle a 3-D model on which simulation surgery can be performed. The principle behind this technology is to first acquire digital data (CT scan data) which is then imported to the RPS to fabricate fine layers or cuts of the model which are gradually built up to form the 3-D models. Either liquid resin or nylon powder or special paper may be used to make these models using the various RPS available today. Selective laser sintering (SLS), which employs a CO2 laser beam to solidify special nylon powder and build up the model in layers is described in this case report, where a 23-year old Chinese female with panfacial fracture and a skull defect benefited from SLS biomodelling in the preoperative workup.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
3/10. Craniofacial impalement injury: a rake in the face.Impalement injuries describe unusual objects and circumstances in which a body part is either partially embedded (one end sticking out) or transected (through-and-through) by a foreign material. In either case, the object remains as part of the wound and is highly conspicuous. These injuries are much more common on the trunk and extremities because of their larger surface areas and the relative ease in which the object may penetrate them without lethal consequences. In the face, however, such injuries are more rare because of protective reflexes that either move the face away from the coming object or permit it only to be deflected away without being embedded. In addition, the face presents a much smaller target than the rest of the body and, therefore, is more infrequently impaled. This paper presents a case that illustrates many of the classic features of the craniofacial impalement-type injury.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
4/10. The use of osseointegrated implants in craniofacial trauma.The objective in treating patients with injuries sustained in craniofacial trauma is to reinstate preinjury facial projection and function. The capability of providing spatially related facial reconstruction is predicated on basic craniofacial surgical principles, generally accepted as the standard of care. These principles include early surgical intervention, immediate bone grafting, and the use of internal rigid fixation. The introduction of osseointegrated dental implants has significantly improved the overall reconstruction of patients with cranio-maxillofacial injuries, including soft tissue repair and cosmetic surgery. The purpose of this article is to review the utilization of dental implants in the context of maxillofacial trauma, using three cases to document the clinical procedure.- - - - - - - - - - ranking = 6keywords = craniofacial (Clic here for more details about this article) |
5/10. Complex-type penetrating injuries of craniomaxillofacial region.Craniofacial traumas are one of the most common clinical events of the 21st century. The possibility of associated injuries of the head and neck may also determine functional and cosmetic problems in these patients. The most frequent pathologic conditions observed are contusions, lacerations, abrasions, avulsions, and the inclusion of foreign bodies. In particular, penetrating injuries represent a rare but complex variety of craniofacial trauma. Generally, the penetrating material is stiff enough to cross through different anatomic structures during a particularly violent collision caused by a road or work accident or during an attack. The therapeutic strategy adopted for this type of patient depends mainly on diagnostic procedures such as skull radiograms in different projections, computerized tomography, magnetic resonance imaging, and, occasionally, echotomography. However, on arrival at the emergency department, the clinical conditions of the patient will determine the type of investigation to be carried out. Last, to prevent any postoperative infections, wide spectrum antibiotic therapy is advisable. Ideally, imaging should be repeated postoperatively to confirm resolution of the initial clinical condition. In this article, the authors describe three unusual clinical cases of patients with penetrating injuries of the head and face together with the protocol adopted for treatment of such complex craniofacial injuries. The three cases described demonstrate that, despite the initial appearance of penetrating wounds, a correct diagnostic assessment followed by a suitable therapeutic protocol can reduce cosmetic and functional defects to a minimum.- - - - - - - - - - ranking = 2keywords = craniofacial (Clic here for more details about this article) |
6/10. Profilocephalometric analysis: a combination of the cephalophotometric and the architectural-structural craniofacial analyses.A number of cephalometric analyses are presently being used in the assessment of dentofacial deformities. These cephalometrics are mostly based on hard tissue assessment alone, although a few methods using soft tissue only or partially hard and partially soft tissues exist. Most of the analyses use angular and linear measurements, although some are based mainly on measurements of relationships. When the various cephalometric analyses are compared, considerable inconsistency comes to light; so much so, that cephalometrics sometimes cannot be considered as a primary diagnostic tool. A combination of two relationship analyses, one based on soft tissue assessment and one based on hard tissue assessment, incorporating the craniofacial complex, is presented to provide a higher degree of diagnostic accuracy. This combination analysis is based on only a few critical hard tissue landmarks of the cranial base that are used for the total assessment of the facial hard, dental, and soft tissues. This has eliminated inappropriate landmarks and lines that existed in each of the original analyses. The cephalophotometric and architectural-structural craniofacial analyses have been adjusted accordingly and renamed the profilocephalometric analysis.- - - - - - - - - - ranking = 6keywords = craniofacial (Clic here for more details about this article) |
7/10. The effects of nasomaxillary injury on future facial growth.The appearance of results of injury to the columella, the nasal septum, and the nasal bones, in particular, has been well described. Anomalies of the maxilla and global facial balance secondary to nasomaxillary injury are less well known. Three cases involving children, aged 11, 14, and 17 years, who had suffered nasomaxillary injury at least 8 years earlier as a result of physical beating, were studied with the use of photographs and architectural craniofacial lateral cephalometric radiographic analysis. The architectural craniofacial analysis of Delaire produced a graphic representation of the resultant maxillofacial deformities rather than a description of the deformities in terms of deviation from a statistical mean. Traumatic injury to the nasomaxillary complex provides an experimental model that implicates the role of the cartilaginous nasal septum and local functional conditions in the growth of the nasomaxillary complex. The importance of the functional premaxillary skeletal unit in balanced facial growth allows better understanding of the pathophysiology of malformation of this region.- - - - - - - - - - ranking = 2keywords = craniofacial (Clic here for more details about this article) |
8/10. The role of primary bone grafting in complex craniomaxillofacial trauma.The role of craniofacial surgical techniques and immediate bone grafting in the management of complex craniofacial trauma has been reviewed. Four hundred and one patients with complex facial injuries have been treated. Two hundred and forty-one primary bone and cartilage grafts have been performed in 66 patients. Complex facial injuries should be managed by direct exposure, reduction, and fixation of all fractures utilizing interfragmentary wiring. Very comminuted or absent bone is replaced by immediate bone grafting, producing a stable skeleton without the need for external fixation devices. Associated mandibular fractures are managed with rigid internal fixation utilizing A-O technique. Results of immediate bone grafting have been excellent, and complications are rare. All deformities should be corrected, whenever possible, during the initial operation. This one-stage reconstruction of even the most complex facial injuries will prevent severe postoperative traumatic deformity and disability that may be extremely difficult or impossible to correct secondarily.- - - - - - - - - - ranking = 2keywords = craniofacial (Clic here for more details about this article) |
9/10. Massive craniofacial injury: initial treatment and methods of reconstruction.A patient with a massive craniofacial injury is presented to illustrate useful flaps that may be used in the reconstruction of this type of injury. Initial management, consisting of basic life support, is indicated, because many patients who appear to be unsalvageable may be successfully restored to an active, productive life. Reconstruction of soft-tissue deficits was accomplished using the forehead and deltopectoral flaps. Although other methods of reconstruction may be used, the forehead and deltopectoral flaps remain among the more reliable flaps to restore thin lining to mucosal and external skin surfaces where bulky tissues are not desired.- - - - - - - - - - ranking = 5keywords = craniofacial (Clic here for more details about this article) |
