What surgical procedure is typically used to treat symptomatic trigeminal neuralgia?

• A. Craniotomy
• B. Mastoidectomy
• C. Microvascular decompression
• D. Transsphenoidal hypophysectomy

Answer: (C)

Microvascular decompression is the preferred surgical procedure for treating symptomatic trigeminal neuralgia. This condition is characterized by severe facial pain that results from irritation or compression of the trigeminal nerve. During microvascular decompression, a surgeon accesses the area around the trigeminal nerve and identifies blood vessels that may be pressing against it. The procedure involves the placement of a cushion, often made of muscle or Teflon, between the nerve and the offending blood vessels to provide relief from the compression. By alleviating this pressure, the surgery can effectively reduce or eliminate the pain experienced by patients. In contrast, the other options are not suitable for addressing trigeminal neuralgia. A craniotomy involves opening the skull but is too broad and often used for different types of infections or tumors. Mastoidectomy pertains to the removal of infected mastoid air cells and does not relate to neuralgia. Transsphenoidal hypophysectomy involves the removal of the pituitary gland and treats conditions related to hormonal imbalance rather than nerve pain. Thus, microvascular decompression is specifically tailored to address the underlying cause of trigeminal neuralgia, making it the correct choice for this type of surgery.
