Reports on surgical treatment for postherpetic trigeminal neuralgia have not been encountered. Hence, we described a case of postherpetic trigeminal neuralgia treated with microvascular decompression and obtained positive outcomes. We also included a literature review of the surgical findings. We reported a case involving a 70-year-old man who had herpes zoster infection in the region of the third branch territory of the right trigeminal nerve for 24 years prior with persistent burning pain and numbness in the region without a trigger. His initial medical therapy provided by the family physician was no longer effective. Facial pain and numbness substantially reduced his quality of life. Therefore, he presented to our department for further treatment. His Barrow Neurological Institute pain intensity score was IV. Magnetic resonance imaging revealed trigeminal nerve compression by the superior cerebellar artery. Written informed consent was obtained, and microvascular decompression was performed using the right retrosigmoid approach. No substantial trigeminal nerve compression by the superior cerebellar artery was observed. However, the trigeminal nerve was atrophied. Subsequently, the superior cerebellar artery was moved to decompress the trigeminal nerve. Internal neurolysis was performed as an additional procedure because the degree of compression was less severe. Postoperative facial pain and numbness improved. Surgical treatment of postherpetic trigeminal neuralgia may be considered based on careful review, informed consent, and precise surgical techniques.
