Jaw Fracture

Fractures Jaw

Jaw fractures are one of the most common maxillofacial injuries encountered in medical practice, with pain, numbness, bleeding, restricted mobility and in rare cases dyspnea presenting as main symptoms. Panoramic radiography and helical computed tomography are the imaging techniques used to make the diagnosis.


Fractures of the mandibular bone, or the lower jaw, are considered as the most common types of maxillofacial fracture encountered in clinical practice [1]. It is much more frequently encountered in males, with an established male-to-female ratio between 3:1 across various reports [2] [3]. In the majority of cases, patients likely suffer from jaw fractures after road traffic accidents, falls, during sports activities or intentionally inflicted injuries (domestic violence, assaults, and child abuse are notable examples) [3], but low-velocity blunt force injuries are described as the predominant mechanism of fracture [4]. Specifically, sports-related injuries are most commonly encountered in younger individuals (boxing and other contact sports), whereas falls (usually on the face) are the main cause of fracture in the elderly population [3]. Fractures of the mandible may occur at the angle, the mandibular symphysis, condyle, and sub condyle, whereas the body may also be a site of the fracture. Common symptoms are the pain, numbness, malocclusion due to the trauma of the teeth that may be displaced or missing, impaired occlusion, bleeding, and limited opening of the mouth due to temporomandibular joint instability and consequent trismus [5]. Preauricular pain is a specific sign of a condylar fracture and unilateral injury to this part of the bone results in deviation of the jaw [5]. Mental nerve paresthesias may be encountered as well [3]. Due to its anatomical characteristics, the mandible is often fractured on more than one site, illustrating the importance of a thorough workup and a detailed assessment. In the setting of more severe trauma, respiratory difficulties, including dyspnea and crepitus, may be observed.

Weight Loss
  • In mandible fractures, patients receiving MMF will have more weight loss and it takes a longer time for them to regain their mouth opening; whereas, higher infection rates are associated with patients receiving rigid internal fixation (RIF).[epainassist.com]
  • This type of injury occurs when the athlete goes over the handlebars and falls directly onto the lower jaw or chin hitting a hard surface.[sportsmd.com]
  • "Given his jaw is stable and not displaced, we will assess him further over the coming days to determine whether he will be available to play this Sunday against the Bombers."[afl.com.au]
  • Commonly, pain, swelling, and bruising can be observed over the fracture area. Stiffness of the affected area is also a common complaint. Opening and closing the mouth during eating or speaking can also be difficult and painful.[ohniww.org]
  • However, because the jawbone is mobile, one of the first symptoms can be severe pain over the site of the fracture with opening and closing of the mouth.[facialtraumamd.com]
Chest Pain
  • You have chest pain when you take a deep breath or cough. You may cough up blood. Your arm or leg feels warm, tender, and painful. It may look swollen and red. When should I contact my healthcare provider? You have a fever. You have a bad headache.[drugs.com]
Jaw Pain

A thorough patient history is the first step in the diagnostic workup of mandibular fractures, in order to assess the mode of injury and determine the presence of other accompanying fractures, for eg. those of the cervical spine, as well as airway damage that may require immediate care [6]. A detailed and complete examination of the head and neck should follow, during which the physician must exclude other accompanying injuries and make the initial diagnosis. Inspection and palpation of the mandible, together with an assessment of teeth for possible injury and jaw mobility can confirm mandibular and other associated fractures, while confirmation can be obtained through imaging studies. Panoramic radiography is considered to be a good initial method for isolated mandibular fractures [5] and is even considered as a superior method to more advanced imaging studies, such as computed tomography (CT) [6]. However, a helical CT scanning has shown to be of significant benefit when evaluating patients for maxillofacial fractures, especially when radiography is not conclusive, and should be performed when possible [5] [6]. Although magnetic resonance imaging is an even more sophisticated method compared to CT and radiography, its use is restricted to assessment of soft tissues in the setting of maxillofacial injuries, and rarely in the examination of bony structures.

Excessive Drooling
  • It may also be painful and difficult to close the mouth, and excess drooling may occur.[fitnesshealth101.com]
