All are true about mandible fracture except:
Answer- C. Anterior superior alveolar nerve is most commonly injuredThe condylar neck is the weakest pa of the mandible and, is the most frequent site of fracture.Trauma to the inferior alveolar nerve leads to permanent numbness of the lower lip and teeth on the affected side.Fractures of the coronoid process of the mandible can result in trismusIn fracture of condyle,displaced fragments leads to malocclusion of teeth & detion of jaw to the opposite side on opening the mouth.X-rays useful in mandibular fractures are PA view of the skull (for condyle), right & left oblique view of mandible & panorexview.Condylar and subcondylar mandible fractures are most often treated by IMF alone.Delayed union and nonunion occur in approximately 3% of fractures.
Condylar neck is most common site
Malocclusion of teeth may occur
Anterior superior alveolar nerve is most commonly injured
Panorex radiographs are useful for diagnosis
