If a blow to the mandible causes deviation to the left during opening, where is the fracture likely located?

When a blow to the mandible results in deviation to the left during mouth opening, it is indicative of a fracture and its location. The mandible normally moves symmetrically; thus, deviation towards one side during opening suggests that there is an issue with the condyle of the opposite side.

In this case, if the jaw deviates to the left while opening, it suggests that there is a dysfunction occurring on the left side. A fracture at the neck of the left condyle would disrupt the normal movement of the left condyle, leading to increased movement or functioning of the right side, which results in the left deviation.

The neck of the left condyle would affect how the mandible operates as it opens, causing it to shift towards the left side where the fracture is located. Proper understanding of the biomechanics of the mandible is crucial here, as the condyle of the mandible plays a pivotal role in the symmetrical opening and closing motions of the jaw.

Fractures in other locations, such as the body of the left condyle or any fractures on the right side, would not typically lead to a left deviation, as they would either cause pain, limited motion, or potential deviation to the right instead. Thus, a fracture
