In a CT reconstruction of a left subcondylar fracture, which condition is most likely to be observed?

• A. Reduced left excursion
• B. Left open bite
• C. Deviation to the right on opening
• D. Left V3 paresthesia

Answer: (D)

In the case of a left subcondylar fracture, the most likely condition to be observed is left V3 paresthesia. The subcondylar region of the mandible is closely associated with the mandibular nerve (V3), which is a branch of the trigeminal nerve (CN V). This nerve provides sensory function to the lower lip, chin, and the anterior two-thirds of the tongue, as well as motor function to the muscles of mastication. When a fracture occurs in the subcondylar area, it can lead to trauma or injury to the mandibular nerve. This may result in numbness or altered sensation in the areas innervated by this nerve, leading to paresthesia, which is a common clinical finding in patients with subcondylar fractures. While the other options describe potential effects of such an injury, they are not as consistently observed. Deviation to the right on opening could occur but is more variable and contingent on the specifics of the fracture and muscle function. A left open bite may not directly correlate with the fracture's immediate presentation, as this would depend more on the function of the residual mandible and dental occlusion. Reduced left excursion can be noted but is not as definitive as
