Microvascular decompression for glossopharyngeal
neuralgia. A personal 118 cases serie
Miami, Florida, November 22th, 2022

2.
• Glossopharyngeal neuralgia (GPN) is a craniofacial pain
syndrome described as electrical discharges in the territory of
the IX cranial nerve.
• A very rare neurovascular compression syndrome/cranial
nerve HDS.
• Incidence 0.2–0.7/100,000 h/year.
• Misdiagnosis TN (V3).
• The MVD/MSD is a non-destructive technique focused on
nerve isolation. Information about short and long-term
efficacy of MVD for GPN is scarce.

As an effective and safe procedure, minimally invasive MSD should be the first
choice as a treatment for GPN, allowing good and excellent relief of
glossopharyngeal neuropathic pain in most cases.
