abstra ct

background &\; objectives: vasomotor rhinitis (VMR) is a non-allergic chronic rhinitis characterized by vascular dysfunction within the nasal cavity and autonomic nervous system imbalance. In cases o f medically refractory and resistant VMR\, endoscopic transnasal vidian ne urectomy—an advanced autonomic denervation surgery—is performed to con trol hypersecretion and vasodilation. This video presentation aims to demo nstrate the vidian neurectomy surgical procedure guided by anatomi cal landmarks\, and to discuss the deep anatomical struct ures of the pterygopalatine fossa\, vidian nerve\, and paranasal region from a surgical perspective.

surgical technique &\; methods: the procedure is performed endoscopically under general anesthesia. F ollowing the identification of the lateral nasal wall landmarks\, a mucope riosteal flap is elevated to access the sphenopalatine foramen. Precise di ssection is required to expose the medial boundary of the pterygopalatine fossa. Upon localization of the vidian canal (canalis pterygoideus)\, the vidian nerve—comprising fibers from the nervus petrosus maj or and nervus petrosus profundus—is identified. Selective neurectomy is performed at this level\, followed by measures to ensure the stability of the surgical site and prevent neural regeneration. The proce dure concludes with the repositioning of the mucosal flap and appropriate stabilization.

conclusion &\; significance: this video presenta tion provides a comprehensive\, step-by-step demonstration of endoscopic t ransnasal vidian neurectomy. By highlighting the critical anatomical landm arks of the pterygopalatine fossa\, this work aims to contribute to the su rgical success and safety of autonomic denervation procedures. It serves a s a practical anatomical guide for clinicians managing refractory vasomoto r rhinitis.

Advances in minimally invasive surgery and a deeper understanding of turbinate physiology have l ed to a more conservative approach in manipulating these structures\, focu sing on preserving turbinate mucosa while reducing airway resistance and i mproving sinus fuction.
