Pterygopalatine ganglion

From WikiMD's Wellness Encyclopedia

(Redirected from Nasal ganglion)

Pterygopalatine ganglion (also known as the sphenopalatine ganglion) is one of the four parasympathetic ganglia of the head and neck. It is the largest of the ganglia and is associated with the maxillary nerve.

Anatomy[edit | edit source]

The pterygopalatine ganglion is located in the pterygopalatine fossa, posterior to the middle nasal turbinate and anterior to the pterygoid canal. It is triangular in shape and is suspended by two roots from the maxillary nerve and pterygoid canal.

Function[edit | edit source]

The pterygopalatine ganglion supplies parasympathetic fibers to the lacrimal gland and mucous glands of the nasal cavity, palate, and pharynx. It also carries sensory fibers from the nasal cavity, palate, and pharynx to the maxillary nerve.

Clinical significance[edit | edit source]

The pterygopalatine ganglion is involved in various clinical conditions such as cluster headache, trigeminal neuralgia, and sphenopalatine ganglion neuralgia. It can be targeted for sphenopalatine ganglion block or sphenopalatine ganglion stimulation in the treatment of these conditions.
