What does Vidian nerve innervate?
The postganglionic fibers form the petrosal nerve, which joins the greater superficial nerve to form the vidian nerve. The vidian nerve therefore contains both the parasympathetic and the sympathetic innervation to the nasal mucosa.
How is Vidian nerve formed?
It is formed by the confluence of two nerves: greater superfical petrosal nerve (from the geniculate ganglion of the facial nerve) carrying parasympathetic fibers from the superior salivary nucleus.
What passes through the Vidian canal?
The vidian canal (VC), a bony tunnel in which the vidian artery and nerve pass, has been widely known as an important landmark to identify the anterior genu of the petrous carotid artery (AGPCA) especially during lateral extended endoscopic endonasal approachs (LEEEAs).
What nerve passes through pterygoid canal?
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.
What does Vidian artery supply?
The vidian artery may become. a major source of blood supply to a variety of deep. facial and paracavernous. lesions.
What is a Vidian Neurectomy?
The vidian nerve is responsible for the production of mucous in the nose and tears in the eyes. A vidian neurectomy is a procedure to block the signals from the vidian nerve in order to provide relief from a chronic nasal drip that has not responded to other treatments.
What does vidian artery supply?
Where is the Vidian canal?
sphenoid bone
The pterygoid canal, also known as the Vidian canal, is a foramen in the base of skull, located in the pterygoid process of the sphenoid bone, superior to the pterygoid plates, and inferomedial to the foramen rotundum.
What passes through pterygopalatine fossa?
The pterygopalatine fossa is an important pathway for the spread of neoplastic and infectious processes: medially: communicates with the nasal cavity via the sphenopalatine foramen, which transmits the sphenopalatine artery, the nasopalatine nerve and the posterior superior nasal nerves.
What are the 4 main segments of ICA?
C1: cervical segment. C2: petrous (horizontal) segment. C3: lacerum segment. C4: cavernous segment.
Where is the Vidian Canal?
Is atrophic rhinitis curable?
There isn’t a cure for atrophic rhinitis, but treatments can reduce the foul-smelling crust and minimize symptoms. They include: Antibiotic ointments that you apply inside of your nose. Moisturizing nasal ointments.
What causes rhinitis Medicamentosa?
Rhinitis medicamentosa (RM), also known as; rebound congestion is inflammation of the nasal mucosa caused by the overuse of topical nasal decongestants.
Is the vidian canal the same as the pterygoid canal?
The pterygoid canal, also known as the Vidian canal, is a foramen in the base of skull, located in the pterygoid process of the sphenoid bone, superior to the pterygoid plates, and inferomedial to the foramen rotundum.
Which nerve is located in pterygopalatine fossa?
The pterygopalatine fossa also contains multiple important structures. This fossa contains the pterygopalatine ganglion. Nerve roots from the maxillary nerve suspend this ganglion. The PPF contains the terminal third segment of the maxillary artery.
What nerve runs through pterygopalatine fossa?
maxillary nerve
At the pterygopalatine fossa, the maxillary nerve (V2) gives rise to the zygomatic nerve, the posterior superior alveolar nerve, and two ganglionic branches, while its main trunk continues into the inferior orbital fissure as the infraorbital nerve.
What is Circle Willis?
Overview. The Circle of Willis is the joining area of several arteries at the bottom (inferior) side of the brain. At the Circle of Willis, the internal carotid arteries branch into smaller arteries that supply oxygenated blood to over 80% of the cerebrum.
How many ICA segments are there?
seven segments
The authors’ classification has the following seven segments: C1, cervical; C2, petrous; C3, lacerum; C4 cavernous; C5, clinoid; C6, ophthalmic; and C7, communicating. This classification is practical, accounts for new anatomic information and clinical interests, and clarifies all segments of the ICA.

What is Pterygomaxillary fossa?
Introduction. The pterygopalatine fossa (PPF) is a cone-shaped depression deep to the infratemporal fossa and posterior to the maxilla on both sides of the skull. The fossa is located between the pterygoid process and the maxillary tuberosity, close to the orbital apex.
