Maxillary fractures are one of the most common emergencies presenting in the acute setting.[1] Due to the complex anatomy within this region and the proximity to vital structures, including the brain, early diagnosis, and precise treatment planning are of paramount importance. Numerous treatment methods are well-practiced globally, and these aim to restore the patient’s quality of life.
Types of facial fractures. The most common facial fractures include: Nasal fractures (broken nose). Forehead fractures (broken frontal bone). Orbital fractures (eye sockets). Zygomatic fractures (cheekbones). Tripod facial fracture (involving your eye socket, cheekbone and upper jaw). Maxillary or mandibular fracture (broken jaw).
A maxillary fracture is a type of facial fracture that involves a break or fracture in the maxilla, which is the upper jawbone. This comprehensive article aims to provide insights into the causes, symptoms, diagnosis, and treatment options for maxillary fractures.
Maxillary sinus fractures (MSFs) are most commonly caused by blunt force trauma to the face. Depending on the magnitude and location of the direct injury, MSFs can vary in appearance and symptomatology. Trauma etiologies include motor vehicle accidents, domestic disputes, falls, industrial accidents, or assaults with or without a weapon.
The term jaw fracture often refers to a break of the lower jaw (mandible). Fractures of the upper jaw (part of the bone called the maxilla) are sometimes called jaw fractures but are usually considered facial fractures. The mandible is most often broken as a result of blunt trauma, such as being punched or hit with a baseball bat or other object.
A maxilla fracture happens when the maxilla becomes cracked or broken. This often happens due to injuries to the face, such as from falling, a car accident, getting punched, or running into an object.
In isolated maxillary fractures, the stable cranium above and occlusal plate below provide sources of stable fixation. One goal of treatment is to restore proper anatomic relationships. In particular, attempt to normalize the integrity of the support bolsters of the facial skeleton, the midfacial height and projection, and dental occlusion and ...
Maxillary fractures account for approximately 6-25% of all facial fractures. In a retrospective study of pediatric midface fractures, Kao et al found that maxillary fractures were the most common. Out of 410 total pediatric midface fractures (218 patients), 125 (30.5%) were maxillary, with 34 of the maxillary fractures being of the nasal ...
Abstract. CT scanning and titanium bone plate and screws have become common place in the treatment of most all bone trauma, and this is certainly true in the facial skeleton. This chapter on maxillary fractures highlights the history of maxillary fracture management, as well as the complexity of repair that exists because anatomic variations of ...
Maxillary fractures are one of the most common emergencies presenting in the acute setting. Due to the complex anatomy within this region and the proximity to vital structures, including the brain, early diagnosis, and precise treatment planning are of paramount importance. Numerous treatment methods are well-practiced globally, and these aim ...
Superiorly, the fractures extend causally, sectioning through the nasal septum. This fracture dissociates the nasal bones, septum, and maxilla from the cranial skull and the lateral midface. LeFort III fractures extend from the nasofrontal suture down through the medial wall and orbital floor to the inferior orbital fissure.
The maxilla is arguably the most anatomically intricate structure of the face and blunt trauma due to interpersonal violence, motor vehicle accidents, gunshot wounds, industrial accidents and falls contribute to etiology of maxillary fractures. Fractures of the midface are often challenging to the maxillofacial surgeon, due to wide variety of ...
As the maxilla is the central bone of the midface it can fracture through various accidents, most commonly the Le Fort fractures which are subclassified into three types: Le Fort I fracture: detachment of the alveolar process from the maxilla in a rectangular form, with the center being at the inferior border of the bony nasal cavity. This ...
A maxillary sinus fracture denotes a distinct category of facial injury that implicates a fracture involving the maxillary sinuses—air-filled cavities within the facial bones. Grasping the precise definition of this injury and comprehending the associated anatomy is imperative for ensuring accurate diagnosis and effective treatment.
Maxillary fractures. Maxillary trauma has been reported to be associated with 14% to 17% of facial injuries. 3 Frequently, the maxilla is fractured in the setting of other facial fractures, most notably the nasal bones and the orbitozygomatic complex. In addition, fractures of the maxilla are associated with a high incidence of concomitant ...
The damage caused by a maxillary fracture can take several weeks or months to heal. During this time, most patients can expect to experience significant swelling and bruising. After the appropriate treatment has been performed, healing can begin to take place. Patients may be asked to adhere to a soft or liquid diet and refrain from strenuous ...
The horizontal fracture line generally passes through the alveolar ridge which is the bony socket that holds the teeth, the lateral nose, and the inferior part of the maxillary sinus, one of the four nasal sinuses that resides near the nose.
Maxillary fractures are linked to alcohol use and illicit drugs, which require higher alcohol tax, greater policing of illicit drugs, and an effective public health message to change these behaviors. Enhancing Healthcare Team Outcomes. The management of a patient suffering from a maxillary fracture will require an interprofessional team approach.
The anterior facial skeleton is composed of the frontal bone, nasal bones, zygomas, maxillary bones, and mandible (figure 1 and figure 2). The sphenoid, ethmoid, lacrimal, vomer, and temporal bones lie deeper within the facial structure, providing support and sites for muscular attachments, including the muscles used for chewing, speaking, and ...
In maxillary fractures occlusion and midface mobility should be checked. Frontal bone fractures. Some individuals have well pneumatised facial sinuses predisposing them to these types of injuries. The drainage of the frontal sinus is extremely poor and assessment always involves the frontonasal ostea.
