Fractures Of The Mandible And The Midface

Blunt facial trauma can lead to fracture of the jaw and other facial bones means. Symptoms depend on the location of the fracture. A dental X-ray or CT imaging is diagnostic. Treatment may include surgery and / or external fixation.

A fracture of the lower jaw (mandibula) can be present if the patient has post-traumatic malocclusion or a focal swelling and sensitivity over a Mandibularsegment. For more information, defects of dental chewing surface, divisions of the alveolar ridge and anesthesia in the area of ??the lower alveolar nerve or mental. Some fractures lead to a palpable instability. Fractures of the mandibular condylar process usually produce preauricular pain, swelling and limited mouth opening (trismus). In a unilateral condylar fracture of the jaw differs in mouth opening the affected side.

In a unilateral condylar fracture of the jaw differs in mouth opening the affected side. Midface fractures involve the range from the upper orbital rim up to the maxillary teeth. They may appear as irregularities of the soft cheeks contours of eminence orbital, the zygomatic arch or Orbitarrandes. With the Le Fort classification, the midface fractures easily be classified (Le Fort classification of midface fractures.). Traumatic malocclusion and fractures of the upper alveolar ridge can be a maxillary fracture, including the chewing surfaces, suggest. An orbital floor (eye lid bruises and tear injuries: Blow-out fracture) is assumed in anesthesia of the infra-orbital nerve, enophthalmos or diplopia. An injury near the orbit requires an eye exam that includes an assessment of visual acuity, the pupils and the extraocular movements. Cheekbone fracture is suspected in trismus and a defect on palpation of the zygomatic arch. If the trauma was severe enough to break the bones of the face, including brain damage and spinal fractures are possible. In severe impact injuries caused by the trauma hemorrhage and edema can affect the respiratory system. Le Fort classification of midface fractures. I: only the lower maxilla; II: the infraorbital rim; III: complete detachment of the midface from the skull (kranofaziale dissociation). Diagnostic x-ray and / or CT A panoramic image of the teeth is the appropriate procedure in an isolated mandibular fractures. A fine-cut CT (1 mm slices) in the axial and coronal plane are made to diagnose facial fractures. Treatment fracture treatment if necessary Endotracheal intubation, antibiotics to maintain the airway patency, in patients with hemorrhage, edema, or extensive tissue destruction be a orotracheal intubation required. The actual treatment of a facial fracture is very complicated and may include an internal fixation. Fractures of the tooth socket fractures that go through a dental specialist, are among the most open fractures. They require antibiotic prophylaxis (typically with a broad-spectrum antibiotic that against anaerobes, is particularly effective for. Example, penicillin) either orally as a liquid or parenteral.Unterkieferfrakturen In a broken lower jaw, the treatment of a soft diet for a maxillomandibular fixation (wiring ranges to jaw closure) to open up a rigid fixation, or both. When a fixation in the first hours after the trauma is possible the closure of the lips or oral injury should be postponed until the fracture has been supplied. In the fixing maxillomandibularen be after the correct occlusion is restored, mounted archwire plastic rails at the upper and lower molars and wired together. Patients with maxillomandibularer fixation should always lead wire cutters with him in case they need to vomit. The fixing can take several weeks. Food intake is to liquids, passed foods and supplements limited. Since only a portion of the tooth surfaces can be brushed, plaque formation, infections and bad breath is a 60-second rinse with 30 mL of 0.12% chlorhexidine every morning and evening prevented. After solution of fixing a jaw workout is usually installed to restore the function. Tips and risks It is important that patients always carry with maxillomandibulärer fixing wire cutters with him. Condylar fractures may require only 2-3 weeks of maxillomandibular fixation, followed by a soft diet. In severe dislocation and bilateral condylar fracture but open reduction and fixation may be necessary. In children, the condylar fracture should not be immobilized rigid as ankylosis and abnormal facial development may result. Normally an elastic fixation about 5-10 days is ausreichend.Frakturen midface fractures midface be treated surgically if they cause malocclusion, enophthalmos, diplopia, infraorbital anesthesia or inakzeptabele cosmetic deformation. Surgical treatment usually consists of an internal fine stabilization with plates and screws. The surgical procedure is often delayed until the swelling has subsided, especially if one indication for surgery is not unique. If surgery is necessary, it is best to carry it out within 14 days after the injury, because the bone hardening makes it difficult to reduce after this time.
