How is Vidian Neurectomy done?
Using a 70-degree endoscope, the vidian nerve is identified on the lateral aspect of the floor of the sphenoid sinus. If not easily visible, the canal is deroofed with a pricking probe, Kerrison’s rongeur, or drill. Using an angled probe, the nerve is transected, and a segment of the nerve is removed.
What does Vidian mean?
Medical Definition of Vidian nerve : a nerve formed by the union of the greater petrosal and the deep petrosal nerves that passes forward through the pterygoid canal in the sphenoid bone and joins the pterygopalatine ganglion.
What is Vidian nerve?
Vidian nerve, also known as the nerve of the pterygoid canal or nerve of the Vidian canal, is so named because of the canal in which it travels: the Vidian canal. It is formed by the confluence of two nerves: deep petrosal nerve (from the sympathetic plexus on the internal carotid artery) carrying sympathetic fibers.
What does the Vidian nerve do?
Vascular innervation Parasympathetic fibres that arise in the sphenopalatine ganglion to form the vidian nerve control vasodilatation and glandular secretion.
How is vidian nerve formed?
The vidian nerve is formed by the confluence of the greater superficial petrosal and deep petrosal nerves and travels in the pterygoid canal carrying the parasympathetic fibers, which synapse in the pterygopalatine ganglion, and the postganglionic fibers are distributed with the branches of the maxillary nerve.
Where does vidian nerve come from?
The nerve of the pterygoid canal (Vidian nerve) is formed by the junction of the greater petrosal nerve and deep petrosal nerve, which passes from the foramen lacerum to the pterygopalatine fossa through the pterygoid canal.

What can a vidian neurectomy be used for?
Background: Vidian neurectomy has in the past been advocated for the treatment of vasomotor rhinitis. With the recent better understanding of nasal and sinus anatomy, the surgical technique and outcomes of this procedure have been reassessed in this preliminary report.
Is the vidian neurectomy effective in treating rhinitis?
Vidian neurectomy has been reported as effective in treating rhinitis, although persistent dry eye symptoms have also been reported as a possible complication.
How many patients have had endoscopic vidian neurectomy?
Methods: A total of nine patients with symptoms of vasomotor rhinitis underwent 14 endoscopic vidian neurectomies between 1998 and 2001. All patients had negative screening for allergies on their serum or on skin-prick tests. The surgical technique for endoscopic vidian neurectomy is presented.
Where is the vidian nerve located in the body?
Vidian nerve is formed at the junction of greater petrosal and deep petrosal nerves. This area is located in the cartilagenous substance which fills the foramen lacerum. of pterygoid canal. It is here the ascending branch from the otic ganglion joins this nerve. pterygopalatine ganglion. It is through this canal the vidian nerve passes.
