Surgical repair of a nerve injury typically aims to restore function to the affected area and alleviate symptoms such as pain or sensory loss. The presence of anesthesia, which indicates a complete loss of sensory function in the affected area, serves as a contraindication for surgical intervention. This is because if there is no sensory function, the potential for recovery of normal nerve function post-surgery is significantly diminished.

In cases where anesthesia is present, the likelihood of successful neural regeneration is reduced since the nerve may have suffered extensive damage. Surgical intervention in this scenario may not provide any benefit, and the risks associated with surgery may outweigh the potential for recovery.

On the other hand, paresthesia, hyperpathia, and allodynia suggest altered sensory responses, which can still indicate some preserved nerve integrity. These symptoms are often seen in cases where there is potential for recovery, making surgery more plausible as a treatment option in those contexts. This suggests that the patient's ability to sense stimuli, even if altered, can lead to a surgical decision depending on the overall clinical picture and nerve function.
