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.
What passes through nasal foramen?
The sphenopalatine foramen connects the nasal cavity and the pterygopalatine fossa, transmitting the nasopalatine nerve, posterior superior nasal nerves, and sphenopalatine artery and vein.
Where is the Sphenopalatine fossa?
The sphenopalatine foramen is a foramen in the skull that connects the nasal cavity with the pterygopalatine fossa….

Is Sphenopalatine fossa and pterygopalatine fossa same?
The pterygopalatine fossa (PPF), less commonly known as the sphenopalatine fossa, is a small but complex space of the deep face in the shape of an inverted pyramid located between the maxillary bone anteriorly, the pterygoid process posteriorly, and orbital apex superiorly.
What passes through the foramen rotundum?
The maxillary nerve
The maxillary nerve (V2) passes through the foramen rotundum and into the infraorbital canal, where, at the pterygopalatine fossa, it branches into the pterygopalatine ganglion, with parasympathetic and sensory branches to the paranasal sinuses.
What 2 foramina are present in the infratemporal fossa?
The roof of the infratemporal fossa contains the foramen spinosum and foramen ovale.
What is infratemporal fossa?
The infratemporal fossa is an irregularly shaped cavity that is a part of the skull. It is situated below and medial to the zygomatic arch. It is not fully enclosed by bone in all directions.
What structure passes through foramen spinosum?
The foramen spinosum permits the passage of the middle meningeal artery, middle meningeal vein, and the meningeal branch of the mandibular nerve.
Which artery is ligated in epistaxis?
Abstract. Epistaxis which is not controlled by anterior and posterior nasal packing is usually treated by ligation or embolization of the arterial supply to the nose. Transantral ligation of the maxillary artery, or embolization of its branches, have recently been considered the treatments of choice.
Where is the most common site of epistaxis?
Most nosebleeds occur in the anterior part of the nose (Kiesselbach’s plexus), and an etiologic vessel can usually be found on careful nasal examination.
What passes through the foramen rotundum and foramen ovale?
The important structures which pass through it are the mandibular nerve, the accessory meningeal artery, the lesser superficial petrosal nerve and the emmissary vein [1].
What are Conchae?
The conchae are structures made of bone inside of your nose. They help control the airflow into your nose. They also clean and warm air that you’ve inhaled so that it’s ready to go to your lungs for respiration.
What is sphenopalatine artery?
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.
What is the Little’s area?
Little’s area (also known as Kiesselbach’s plexus) is found on the anterior nasal septum (Fig. 1) and is an anastomosis of 5 arteries: anterior ethmoidal artery, posterior ethmoidal artery, sphenopalatine artery, greater palatine artery, and the septal branch of the superior labial artery.
