Although radiofrequency thermoablation (RFA) of the gasserian ganglion is established, peripheral nerve RFA remains underutilized, particularly in anatomically complex cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>A 62-year-old man developed severe left maxillary (V2) facial pain following sinus surgery, refractory to multiple pharmacological therapies and prior gasserian balloon rhizotomy. A diagnostic infraorbital nerve block produced significant temporary relief, supporting a peripheral pain generator and RFA consideration. An initial infraorbital nerve RFA performed with fluoroscopic guidance failed to provide durable benefit. A subsequent CT-guided infraorbital nerve RFA resulted in marked pain reduction. The patient later developed localized recurrent dysesthesia, prompting a third CT-guided, navigation-assisted RFA with sustained improvement. At the last follow-up (8, 6, and 3 months after the first, second, and third RFAs, respectively), his visual analog scale pain score improved from 10 to 2, with approximately 80% reduction in pain flares and significant quality of life improvement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>CT-guided infraorbital nerve RFA is a minimally invasive and effective option for refractory PTTN.
