Symptoms after mandibular fracture

summary

It can be said that every bone in the human body is likely to be fractured, and so is the mandible. If we encounter the mandible when we fall, the phenomenon of mandible fracture will also occur. Let's introduce the symptoms of mandible fracture.

Symptoms after mandibular fracture

Median chin fracture: the fracture line can be single, multiple fracture lines and comminuted fractures. The traction force on both sides of the fracture line is basically equal, and there is often no obvious dislocation; In the case of double bone broken line, the fracture piece of the median fracture segment can be displaced downward and backward due to the traction of genioglossus muscle and chin potential according to the skeletal muscle; In case of comminuted fracture or bone defect, the fracture segments of both sides were displaced to the midline due to the guidance of the mandibular hyoid muscle. Note that the latter two kinds of fractures can make the tongue fall back and cause dyspnea, even the risk of suffocation.

Mental foramen area fracture: but lateral mental foramen area fracture, fracture line is vertical, the mandible is divided into two different fracture segments, broken bone piece attached to the side of all the maxillary muscle (masseter muscle, pterygoid muscle, temporal muscle), the main pulling force makes the fracture segment upward, inward displacement. The long fracture segment was continuous with the uninjured mandible, with the traction of bilateral mandibular muscles, which shifted downward and backward and slightly deviated to the affected side. At the same time, the uninjured joint was used as the fulcrum, and the bone was slightly rotated inward to make the anterior teeth occlude.

Dysfunction: occlusal disorder, limited mouth opening, local bleeding, hematoma, edema, pain, etc., resulting in chewing, breathing, swallowing, language and other dysfunction. Severe comminuted chin fracture may cause respiratory distress and obstruction, which should be paid enough attention to.

matters needing attention

It can be seen that the symptoms of mandibular fracture are still relatively obvious, at least the external manifestations of mandibular fracture can be seen by ordinary people. Therefore, if you have the above symptoms in your mandible, you should not bear the pain, and you'd better go to the hospital for examination.
