Mandibular fractures are the most common fractures of facial bones. If the fracture is detected and the occlusion is affected, surgery is the best option. Motor vehicle accidents and fall injuries are the most common reasons for combined injuries of maxillofacial and cervical spine (c-spine). The most common scenario is the cooccurrence of midfacial trauma and upper c-spine injuries. Despite the low incidence of the cooccurrence of spinal injuries and maxillofacial trauma, it is crucial to have guidelines that assess and manage this situation because of its severe outcomes.

| Introduction|| |
Combination of the cervical spine fractures with maxillofacial trauma have serious outcomes because of the high potential for mortality and neurologic morbidity. Therefore, the incidence of maxillofacial fractures complicated by spinal trauma, is of significant concern to the craniomaxillofacial surgeon. In this case report, authors describe the stages of diagnosis and treatment of such a patient.
| Case Report|| |
An 8-year-old male child was admitted to our emergency room with maxillofacial and spinal trauma after a car crash. He was conscious, oriented, and cooperative. His blood pressure was 106/62 mmHg (normal). His pulse was 120 bpm (high) and temperature was 36.6°C (normal). He had a jaw and neck pain. His jaw and lower face were swollen. A hard neck collar was placed immediately. Malocclusion was detected during his examination. He had a neck spasm and limited neck movement. After the patient was stabilized, his computed tomography (CT) scans were taken.
Through CT scans, he was diagnosed with a mandibular double-fracture pattern combined within body and the parasymphisis region complicated with an odontoid fracture. Since he had malocclusion, we decided that it would be best to perform early open reduction and fixation.
Neurosurgeons' decision was to treat him nonoperatively for the cervical fracture. This treatment required immobilization of the neck until the fracture was healed. Therefore, the mandible fixation had a very high risk of neurodamaging in case of a minimal displacement of the neck during the operation. He was meticulously entubated with a fiberoptic laryngoscope by a senior member of the anesthesiolgy staff. Patients neck collar was kept intact during this procedure [Figure 1]. Intubation is very risky for neck trauma patients; therefore, it is very important for the anesthesiology team to be as experienced, skilled, and careful as the plastic surgery team. While intubating, it was important not to move his head or neck at all. An arch bar was used to gain proper maxillary-mandibular occlusion before fixating a stable plate. Circummandibular wires were used to hold the arch bar in position. Nonabsorbable plates were preferred due to excessive prices of the absorbable plates. Rigid fixation was accomplished with two-to-four-hole 12.0-mm spaced, mini, straight plates (1.9 thickness) (Trimed® Ankara, Turkey) and eight screws (2.0 mm diameter/7 mm length) via intraoral approach [Figure 2]. The plates were positioned at the inferior lower border of the mandible not to harm the permanent tooth buds due to the patient's young age. The arch bar was left to keep the occlusion after the operation and was removed 1 month later. There were no early or late complications after the surgery.

| Discussion|| |
Mandibular fractures are the most common fractures of facial following nasal bone fractures. When a mandible is fractured, the occlusion of a patient is usually affected. If the fracture is detected and the occlusion is affected, surgery is the best option. The treatments of these fractures are important for the patient to restore proper speech, mastication, and swallowing. For the optimal timing of the surgery, concomitant injuries and their type and severity should be taken into account. Multidisciplinary modality should be considered. Early reduction and fixation reduce the risk of nonunion, malunion, osteomyelitis, and malocclusion.
Motor vehicle accidents and fall injuries are the most common reasons for combined injuries of maxillofacial and cervical spine (c-spine). The most common scenario is the cooccurrence of midfacial trauma and upper c-spine injuries. The most common c-spine that is involved is C2. One half of the neck's motion (flexion, extension, and especially rotation) is achieved by atlanto-axial junction. For this reason, C2 is the most common c-spine to be affected in a trauma patient. A strong ligament limits the rotation of the neck. This restriction is lost when the odontoid is fractured. The anterolisthesis or retrolisthesis of the C1–C2 complex in relation to C2 body may result in serious neurological complications. Odontoid fractures at the junction of dens and the body are the most common types (Type II) of axis fractures. It is important to note that up to 40% of the odontoid fractures are fatal at the time of the accident. Odontoid fractures are not necessarily treated operatively. Nonoperative immobilization methods are frequently used. The treatment options are considered and decided by a neurosurgeon for cervical fractures.
When the trauma is complicated and the airway is difficult to obtain, the examination and imaging of the patient can be challenging. Urgent recognition of a cervical injury is crucial. Careful intubation of the patient beforehand can be the only option for those cases. Therefore, it is very important for a plastic surgeon to be aware and cautious about a cervical injury when examining a patient with maxillofacial trauma. Furthermore, in case of an operation, neurological damage is usually underestimated and immobilization is not performed adequately as it should be. Cervical immobilization devices should not be removed until spine injury has been excluded. The mortality rate of maxillofacial injuries that are complicated with cervical injuries is relatively high (8%). 10%–25% of the patients with facial fractures are reported to have delayed diagnosis of spinal fractures. There are reported cases in which the spinal injury was detected only after the maxillofacial reduction. As a result, all patients with a facial trauma should be considered to have spinal injuries up front.
Despite the low incidence of the cooccurrence of spinal injuries and maxillofacial trauma, it is crucial to have guidelines that assess and manage this situation because of its severe outcomes. It is very important to know about and foresee the outcomes of a multitraumatic patient especially for maxillofacial surgeons because, in case of an operation, the neck is often mobilized for anesthesiology procedures and also during the reduction of the facial bones. If it is necessary to operate the patient because of her/his facial trauma, it is crucial to immobilize the neck with neurosurgeons and anesthesiologists and then despite its technical difficulties operate with caution without moving the neck at all.
