Thermal radiofrequency of the sphenopalatine ganglion in persistent idiopathic facial pain using a suprazygomatic approach: Case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The sphenopalatine ganglion (SPG) is a key structure in the pathophysiology of various craniofacial pain syndromes with autonomic manifestations, integrating parasympathetic, sympathetic, and trigeminal fibers within the trigemino-autonomic reflex. Modulation of these pathways through nerve block or radiofrequency has shown effectiveness in managing pain and associated autonomic symptoms. However, no previous reports have described the use of a suprazygomatic approach for thermal radiofrequency of the SPG. Case report: We present the case of a 70-year-old man with a one-year history of left-sided persistent idiopathic facial pain (PFPS), characterized by paroxysmal exacerbations in the V1-V2 territories, epiphora, and nasal congestion, without evidence of structural lesions or classical neuropathy. After unsuccessful treatment with carbamazepine and a diagnostic Gasserian ganglion block, a suprazygomatic SPG block with 1 % lidocaine was performed, achieving 80 % pain relief lasting four weeks. Upon recurrence of pain, fluoroscopy-guided thermal radiofrequency (TRF) of the SPG (80 °C, 60 s) was conducted, resulting in sustained improvement (NRS 1/10) at six months, with no sensory deficits or adverse effects. This case demonstrated that the suprazygomatic approach provides a safe route to access the pterygopalatine fossa. Conclusion: Thermal radiofrequency of the SPG via the suprazygomatic approach may represent an effective and safe alternative for treating persistent idiopathic facial pain with autonomic features.
