In the excision of a schwanoma, what is the preferred approach regarding the nerve?

• A. Completely remove the nerve
• B. Cut the stalk and spare the nerve
• C. Remove the nerve with surrounding tissue
• D. Leave the neurofibroma intact

Answer: (B)

In the excision of a schwannoma, the preferred approach involves cutting the stalk and sparing the nerve, which aligns with preserving the nerve's function and minimizing morbidity. Schwannomas, or neuromas, are typically benign tumors that arise from Schwann cells, which are responsible for myelinating peripheral nerves. When excising these tumors, the goal is to remove the tumor while maintaining as much nerve function as possible. By cutting the stalk while sparing the nerve, the surgeon can effectively remove the schwannoma with a reduced risk of complications, such as neuropraxia or chronic pain from nerve damage. This approach helps to maintain the integrity of the nerve itself, allowing for better functional outcomes for the patient after the surgery. In contrast, completely removing the nerve or its surrounding tissue can lead to significant sensory or motor deficits, making it an undesirable choice. Leaving the neurofibroma intact does not provide therapeutic intervention and would not address the issues associated with the tumor, while removing the nerve with surrounding tissue increases the risk of poor functional outcomes. Thus, the correct approach prioritizes cutting the stalk while preserving the integrity of the nerve.
