In cases of unilateral mandibular fractures, the deviation of the mandible upon movement can provide insight into the location of the fracture. When there is a unilateral fracture with deviation to one side, it typically indicates that the opposing side is not able to function properly, hence causing the mandible to deviate toward the fractured side when force is applied.

In this scenario, with a leftward deviation of the mandible, it is suggestive that the fracture is likely located on the left side. Specifically, fractures of the neck of the mandible, including the area around the condyle, often lead to significant restrictions in movement and can cause the mandible to shift toward the injured side. This is due to the fact that the muscles restraining the movement, such as the lateral pterygoid, may not be able to pull effectively on the fractured side.

A fracture at the neck of the left condyle would typically present with limited movement and the resultant leftward deviation when the patient attempts to open their mouth. The condyles play a critical role in the stability and mobility of the mandible, and damage to the neck would lead to significant consequences in the function of the jaw.

By contrast, fractures at positions on the right side or at different
