What passes through the sphenopalatine foramen?
What passes through the sphenopalatine foramen?
Nasopalatine Nerve It travels through the sphenopalatine foramen to enter the nasal cavity and crosses its roof to reach the nasal septum. It descends in an oblique direction anteroinferiorly between the periosteum and mucous membrane of the nasal septum within a groove on the vomer bone.
Where does the sphenopalatine artery come from?
The sphenopalatine artery is a terminal branch of the internal maxillary artery originating from the external carotid artery system. [4] The SPA is the major blood vessel to the nasal cavity mucosa: supplying the superior, middle, and inferior turbinate; lateral nasal wall; and nasal septum.
Where is the sphenopalatine artery located?
Anatomy of the Sphenopalatine Artery The sphenopalatine foramen is located on the lateral nasal wall at the superior aspect of the vertical plate of the palatine bone. It can be found where the inferior portion of the middle turbinate basal lamella meets the medial orbital wall.
What are the 3 parts of the maxillary artery?
Pterygopalatine (3 part) of the maxillary artery[4]:
- Pharyngeal artery: enters the palatovaginal canal.
- Greater palatine artery: enters the greater palatine foramen.
- Artery of the pterygoid canal.
- Sphenopalatine artery: enters the sphenopalatine foramen.
- Posterior superior alveolar artery.

What is sphenopalatine artery ligation?
Objective: Sphenopalatine artery ligation is a commonly employed surgical intervention for control of posterior epistaxis unresponsive to nasal packing.
Why is sphenopalatine artery called artery of epistaxis?
The sphenopalatine artery, formerly known as the nasopalatine artery, is the terminal branch of the maxillary artery that is the main supply to the nasal cavity. It is colloquially know as the artery of epistaxis given its common involvement in cases of nose bleeds.
What are the 5 branches of the maxillary artery?
Five branches, each of which enters a bony foramen:
- deep auricular artery (enters squamotympanic fissure)
- anterior tympanic artery (enters petrotympanic fissure)
- middle meningeal artery (enters foramen spinosum)
- accessory meningeal artery (enters foramen ovale)
- inferior alveolar artery (enters mandibular foramen)
Which structure passes from foramen spinosum?
The foramen spinosum permits the passage of the middle meningeal artery, middle meningeal vein, and the meningeal branch of the mandibular nerve.
