Frontal bone fracture treatment is still an issue of research in craniofacial surgery and neurosurgery. The aims of the treatment are to reduce the complication risks and to keep the aesthetic of the face. Before the management of this fracture type, it is necessary to consider the permanence or not of the frontal sinus function. Rapid prototyping has been an aid tool on planning and simulation of the surgical procedure, improving the diagnostic quality and the implant manufacture, beyond reducing the operative time. Among the used materials on treatment of these fractures, titanium mesh shows large versatility and ease of handling. Poly(methyl methacrylate) has been used in defects of partial thickness or irregularities on cranial surface. The aim of this study is to report a case of a patient presenting sequelae of large fracture of anterior wall of frontal bone, treated by a titanium mesh associated with the customized poly(methyl methacrylate) implant from the rapid prototyping. It could be concluded that the use of this technique showed itself effective on patient treatment, and rapid prototyping demonstrated being a valuable tool showing predictable and satisfactory results.
Trauma is one of the leading causes of death worldwide. Due to its anatomy and position in the facial skeleton, the orbit becomes a region susceptible to trauma which may also involve the penetration of foreign bodies (FBs). These events can have serious repercussions depending on their extent due to the proximity of the orbit with other noble structures of the face and skull. Because of this, a system of prehospital management of traumas must be established, in order to promote a better prognosis for patients. The present study aims to report the case of a patient suffering from a motorcycle accident with multiple fragments of FBs in the region of orbit-zygomatic-maxillary complex. The emergency surgical removal of the fragments was performed by a multidisciplinary team, involving Ophthalmology and Oral and Maxillofacial Surgery and Traumatology (OMST). Wound cleansing and debridement were performed with subsequent removal of the foreign bodies by the OMST team, in addition to the reduction and fixation of related fractures. As for Ophthalmology, the evisceration of the affected eye was performed due to its anatomical and functional impairment. The patient is 12 months postoperatively, with no aesthetic or functional complaints regarding OMST. The anatomical knowledge of the traumatized region, besides the establishment of the conduct regarding the removal of possible associated foreign bodies are required so that the success of the treatment can be obtained, aiming to minimize the damages to the patient.
Poor proprioception, weakness, and impaired reflexes increase the incidence of facial fracture in the elderly. Mandibular fractures in these people range from 10.1% to 56%. Fragment reduction and fracture consolidation are difficult due to bone atrophy, decreased capacity for bone regeneration, and lack of anatomical landmarks to guide the alignment of the fragments. This study reports 2 patients with different conducts regarding the treatment of bilateral fractures in atrophic mandible. The first patient refers to the removal of plates of the 2.4 mm system with low profile, which failed during the mandibular function, being replaced by the 2.4 mm system with high profile. The 2nd clinical reports the use of the 2.0 mm system only to simplify the mandibular fracture, and then reconstructing that with a 2.4-mm system with high profile, using the load bearing principles. Regarding mandibular fractures, an important goal is to neutralize the muscle action aiming the bone stability. There are several methods to treat that the indication should consider the load bearing and load sharing concepts. The incorrect fixation choice in these patients can result in complications as bad union, material failure, infection, and consequent treatment failure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
