Personal bones Forecasts PA occipital-mental view provides an excellent demonstration of the upper and middle third of the face including the orbital field, the frontal sinuses, Zygomatic arch and maxilla Chicago:
With 30 degrees caudal angles of the orbits showed worse. However, Zygomatic arch and the wall of the maxillary Chicago clearly visible:
Line 1: Line 2: Comparison of the injured party with an intact side. In the facial skeleton, there are relative strengths, which are usually devoid of fracture lines. These include:
The most common of the orbit to support the weaker sex change, and this injury, if occurring in isolation, could lead break fracture. Hitting the world leads to an increase intraorbitalnoho pressure. This leads to the destruction of a thin plate of bone formation sex inclination (ie the roof of the maxillary sinuses). Some of the orbital contents such as fat and muscle hernia down in the maxillary sinus by radiography in soft tissue tear or polipovidnyh mass in the roof of the maxillary sinus:
hernia through the medial wall may also occur. Air from the maxillary sinus lattice or can get into orbit, causing orbital emphysema. It is widely known as a black mark eyebrow:
Zygomatic bone has three different limbs; orbital process leading to zygomatico-frontal suture, Zygomatic arch and maxilla process around the top and side edges of the upper jaw Chicago. Injury to the facial skeleton wants to rid areas of relative strength and body Zygomatic bone is one such area. It follows that the fractures may be resistant to these three limbs and such injury is called a tripod fracture. Radiologically it is a common injury seen in the form:
Extensions zygomatico-frontal suture. Zygomatic arch fracture. Fracture of lower orbital edge, passing through the anterior and lateral walls of maxillary sinuses.
And OM and OM 30 views identify these fractures, together with the swelling of soft tissues Zygomatic for recovery and turbidity or air-fluid level in the maxillary sinus. Often only direct PA to determine diastase on zygomatico-frontal suture. They usually consist of three lines of fracture of the medial and inferior displacement of the fragments. Often, however, apparently isolated fracture Zygomatic arch is actually part of a complex fracture tripod. Classification of fractures of the upper jaw again should the concept of areas of relative strength within the facial skeleton. There are three main lines of fracture, corresponding to the relative weakness, and they called LeFort fractures. By definition, these fractures should be flogged alar process of sphenoid bone. This transverse fracture through the lower Chicago maxilla, which separates from the alveolar process of maxilla. LeFort I demonstrated in the opinion of OM with fractures through medial and lateral wall of the maxillary Chicago and nasal septum. This is a pyramidal fracture, which separates the central part of the face. The film defines OM LeFort II fractures of the tear through bone, the medial orbital wall, infra-orbital region and the lateral wall of the maxillary Chicago. This fracture is characterized by division of all the facial skeleton with a skull. The back side of the fracture extends down the back wall of the sinus of the upper jaw. The destruction of lines will be visible in the view AM extends from the orbital and medial region of nasoethmoid ethmoids behind. Orbits appear elongated with large diastase of zygomatico-frontal sutures, or broken orbital bone Zygomatic process. In practice, this classification is more simplified, but in fact, cracks tend to be more difficult. There may be a combination of effects such as LeFort II on the one hand, and LeFort III, on the other. In addition, these injuries associated with serious injury in these patients usually ask a CT scan and a simple example of a classic movie LeFort fractures are rare. This is a great way to show almost all fractures of the mandible, including the coronary and myschelkovoho processes. Note, however, sometimes seam fractures Mantu can not be seen. RAM should be supplemented with nylon jaw set displacement of fractures. This will show the body and symphysis Mantu and provide tangential view of branches and neck condyle:In the absence of OPG, lateral oblique will show the body and branches on each side. Articulation in the temporomandibular joint can be evaluated:
mandibular fractures usually occur in more than one place, because only one was identified, another should be sought. The second injury may fracture or dislocation of the temporomandibular joint. The lower jaw consists of inner and outer bark protecting the brain cavity. The destruction of lines can be defined on the inner and outer bark, but it is a crack:
air in the throat can be identified by OPG overlying the knee joint and branches. This should not be mistaken for fracture. Fractures and coronal myschelkovoho processes often occur at their bases and can be difficult to imagine. PA jaw show medial (or, rarely lateral) knee joint angles in the alar muscles:
fractures are classified lasix 60 mg iv as favorable or unfavorable. Favorable fracture which runs into the application and alignment of natural draft attached muscles. Unfavorable fractures are those that are displaced by the gravity attached muscles. After the diagnosis of fractures, it is important to detect any abnormal condition of the teeth, which is destruction. This is best shown by the OCG. Fracture, which extends in periapical abscess can lead to slow healing and osteomyelitis. .
