BACKGROUND: Postherpetic neuralgia (PHN) is the most common complication of shingles and can be a significant bur¬den to patients due to pain and disability. Currently, treatment options are limited. In refractory cases, neuromodulation using spinal cord stimulation (SCS) and peripheral nerve stimulation (PNS) have been used but is considered experimental due to limited evidence.
CASE REPORT: We report 2 cases who experienced successful treatment of refractory PHN. Patients underwent dorsal root ganglion (DRG) stimulation at the thoracic level for the treatment of refractory PHN.
CONCLUSION: Both patients showed significant improvement in pain at 24 and 36 months after a DRG stimulation trial and implantation. We report the successful use of DRG stimulation for the treatment of PHN.
