Long-term outcomes after microvascular decompression for glossopharyngeal neuralgia

Area of Science:

• Neurosurgery
• Neurology
• Pain Management

Background:

• Glossopharyngeal neuralgia (GPN) is a debilitating condition characterized by severe facial pain.
• Microvascular decompression (MVD) is a surgical option for GPN, but long-term outcome data, especially concerning pain location and redo procedures, are limited.

Purpose of the Study:

• To evaluate the long-term efficacy and safety of MVD without neurectomy for classical GPN.
• To specifically analyze the impact of pain location and the role of redo MVD on treatment outcomes.

Main Methods:

• Retrospective cohort study of 29 consecutive patients undergoing MVD for GPN between 2013 and 2021.
• Inclusion of patients who had previously undergone unsuccessful procedures.
• Assessment of outcomes through medical record review and clinical/telemedicine follow-up.

Main Results:

• 86% of patients achieved complete pain relief at a mean follow-up of 65.3 months.
• Redo MVD provided complete pain relief in 3 of 4 patients.
• Complications were low, occurring in 10% immediately and 11% long-term.

Conclusions:

• MVD without neurectomy is a safe and effective long-term treatment for classical GPN.
• Redo MVD is a viable option for patients with persistent neurovascular compression.
• Symptom radiation patterns did not correlate with pain relief outcomes.
