Posterior fossa microvascular decompression effectively treated intractable trigeminal neuralgia. This surgical procedure offered significant pain relief for most patients, demonstrating a safe and viable treatment option.

Area of Science:

  • Neurosurgery
  • Neurology
  • Pain Management

Background:

  • Trigeminal neuralgia (TN) is a chronic pain condition affecting the trigeminal nerve.
  • Intractable TN often requires surgical intervention when conservative treatments fail.
  • Microvascular decompression (MVD) is a surgical technique to alleviate nerve compression.

Purpose of the Study:

  • To evaluate the efficacy and safety of posterior fossa microvascular decompression for intractable trigeminal neuralgia.

Main Methods:

  • Eleven patients with medically refractory trigeminal neuralgia underwent posterior fossa microvascular decompression.
  • Outcomes including pain relief, operative complications, and neurological deficits were assessed.

Main Results:

Related Experiment Videos

  • Complete pain relief was achieved in 7 patients (63.3%).
  • Partial symptom relief was observed in 3 patients (27%).
  • No operative mortality occurred; complications included transient lower cranial nerve palsies (2 patients) and one CSF leak requiring a lumbar drain.

Conclusions:

  • Posterior fossa microvascular decompression is an effective and safe treatment for intractable trigeminal neuralgia.
  • MVD offers superior outcomes compared to ablative neurosurgical procedures for TN.
