Why does pterygopalatine ganglion occur?

The pterygopalatine ganglion supplies the lacrimal gland, paranasal sinuses, glands of the mucosa of the nasal cavity and pharynx, the gingiva, and the mucous membrane and glands of the hard palate. It communicates anteriorly with the nasopalatine nerve.

What is Sluder’s Syndrome?

Also known as Sluder’s neuralgia, this facial pain disorder is characterized by unilateral headache behind the eyes with pain in the upper jaw or soft palate, with occasional aching in the back of the nose, the teeth, the temple, the occiput, or the neck.

Which affliction is known as sphenopalatine?

This is known as brain freeze although the correct medical term is sphenopalatine ganglioneuralgia. Brain freeze may be a more popular name, but it also goes by ice cream headache and this makes perfect sense as ice cream is a known culprit of this painful but harmless affliction.

What are the clinical effects of irritation of pterygopalatine ganglion?

Clinical Significance The pterygopalatine ganglion is theorized to be a component for a group of headache disorders classified as trigeminal autonomic cephalalgias (TACs) which present as unilateral headaches with ipsilateral autonomic features (lacrimation, rhinorrhea, nasal congestion, eyelid edema, and ptosis).

What nerves synapse at pterygopalatine ganglion?

the facial nerve
The parasympathetic root is derived from the greater petrosal nerve via the pterygoid canal and consists of preganglionic parasympathetic fibers from the facial nerve, which synapse within the ganglion.

Where is Pterygopalatine ganglion located?

pterygopalatine fossa
The sphenopalatine (pterygopalatine) ganglion resides in the pterygopalatine fossa, located posterior to the middle nasal concha and anterior to the pterygoid canal. It is adjacent to and inferior to the maxillary nerve, a branch of the trigeminal nerve, and connects with it via the pterygopalatine nerves.

Where is sphenopalatine ganglion located?

The sphenopalatine ganglion (SPG) is a collection of nerves (sympathetic, parasympathetic and some sensory). It lies in a bony cavity called the pterygopalatine fossa, which is deep in the midface.

What is the pterygopalatine ganglion?

The pterygopalatine (sphenopalatine) ganglion is one of four small parasympathetic ganglia found in the head. It resides in the pterygopalatine fossa, which is located in the superior pterygomaxillary fissure, in the anterosuperior part of the infratemporal fossa (medial to the zygomatic arch and the coronoid process of the mandible ).

What is the sphenopalatine ganglion?

The sphenopalatine ganglion (pterygopalatine, nasal, or Meckel’s ganglion) is a parasympathetic ganglion that is located in the pterygopalatine fossa ( Fig. 11-8A ), posterior to the middle turbinate. Its sensory root is derived from sphenopalatine branches of the maxillary nerve, cranial nerve (CN) V 2.

How do preganglionic axons reach the pterygopalatine ganglion?

Preganglionic axons reach the pterygopalatine ganglion from the facial nerve via the greater superficial petrosal nerve and the nerve of the pterygoid canal (Vidian nerve).

What is the parasympathetic ganglion?

It is one of four parasympathetic ganglia of the head and neck, the others being the submandibular ganglion, otic ganglion, and ciliary ganglion .
