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

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 structu
