Mandibular ramus fractures can be managed with either rigid fixation or functionally stable fixation. As the bone that stretches from the underside of either ear and gives rise to the bottom teeth, the mandible consists of the body, which is the horizontal portion crossing the chin, and the ramus, the vertical section beneath each ear.

When performed bilaterally they divide the mandible into two smaller condyle bearing segments and a large segment consisting of the anterior ramus and … Ask the patient to open the mouth and leave it slightly ajar. In the case of concurrent fractures of the ascending ramus, a combined submandibular and preauricular approach may be warranted. Thus, the nerve is inaccessible once it has entered the bony cavity, and blockade must be performed at either the mandibular foramen or the mental foramen. The parotid gland is the largest major salivary gland and secretes a serous saliva. Figure 20. Once the needle is completely inserted, 1 to 3 mL of local anesthetic should be injected. This point of divergence is marked by the mandibular foramen. The mandible (or lower jaw bone, latin: mandibula) is the only movable cranial bone.
