The sphenopalatine artery travels within the pterygopalatine fossa and enters the nasal cavity through the sphenopalatine foramen within the posterior portion of the superior meatus.
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.
Which artery is known as artery of epistaxis?
Sphenopalatine arterySourcemaxillary arteryBranchesposterior lateral nasal branches posterior septal branchesSuppliesfrontal, maxillary, ethmoidal, and sphenoidal sinusesIdentifiers
Does the sphenopalatine artery supply the hard palate?
The blood vessel supplies the hard palate mucosa, gingival tissue, and palatine tonsils 5. The greater palatine artery also contributes to the Kiesselbach plexus of the nasal septum via anastomoses with the sphenopalatine artery 3,5.What artery passes through sphenopalatine foramen?
The sphenopalatine artery arises from the pterygopalatine segment of the maxillary artery. Within the pterygopalatine fossa, the artery passes through the sphenopalatine foramen to reach the upper nasal cavity behind and slightly above the middle nasal concha.
How do you Spgate the sphenopalatine artery?
An incision is made just posterior to the posterior attachment of the middle turbinate. The mucosal flap is then carefully elevated to reveal the sphenopalatine artery, which is then clipped and ligated.
How do you find the sphenopalatine artery?
The location of the sphenopalatine foramen (SPF) is identified within the superior meatus after elevation of a mucoperiosteal flap and identification of the crista ethmoidalis from the posterior aspect of the middle meatus. Opening the maxillary sinus may assist the surgeon if these landmarks are not quickly found.
Where is the maxillary artery located?
The maxillary artery is a branch of the external carotid artery and supplies many structures on the face. The maxillary artery arises posterior to the mandibular neck, traverses the parotid gland, and passes forward between the sphenomandibular ligament and ramus of the mandible.Where are your carotid arteries located in your neck?
There are two carotid arteries: one on the left and one on the right. In the neck, each of them branches off into an internal carotid artery and an external carotid artery. The position of the branched carotid arteries is where a person can feel the pulse in their neck, just under the jaw.
Where is posterior auricular artery?The posterior auricular artery is a smaller muscular artery that branches from the external carotid artery. This artery travels to the region posterior to the ear. The function of the posterior auricular artery is to perfuse the scalp and the ear.
Article first time published onWhat are the three types of epistaxis?
An anterior nosebleed occurs when the blood vessels in the front of the nose break and bleed. A posterior nosebleed occurs in the back or the deepest part of the nose. In this case, blood flows down the back of the throat. Posterior nosebleeds can be dangerous.
What is the ICD 10 code for epistaxis?
R04. 0 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
Where is Little's area?
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.
What is Sphenopalatine fossa?
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 is a sphenopalatine ganglion block?
Sphenopalatine ganglion block is a procedure in which a local anesthetic is delivered to the sphenopalatine ganglion (SPG)—a group of nerve cells located behind the nose—to relieve headache pain.
How do you remember maxillary arteries?
A mnemonic for remembering the branches of the maxillary artery is: DAM I AM Piss Drunk But Stupid Drunk I Prefer, Must Phone Alcoholics Anonymous.
What is a sphenopalatine artery ligation?
An endoscopic transnasal approach for ligation of the terminal branch of the internal maxillary artery, the sphenopalatine artery, provides an alternative to transantral ligation. We have used endoscopic ligation of the sphenopalatine artery to treat 38 patients requiring surgical therapy for epistaxis.
What is the main source of arterial blood to the nose?
The blood that perfuses the nose is mainly from branches of the facial artery. The branches of the facial artery and the superior labial artery perfuse the nose via the septal branches, the angular artery, the external nasal artery, the dorsal nasal artery, and the lateral nasal artery.
What are the branches of the maxillary artery?
- deep auricular artery (enters squamotympanic fissure)
- anterior tympanic artery (enters squamotympanic fissure)
- middle meningeal artery (enters foramen spinosum)
- accessory meningeal artery (enters foramen ovale)
- inferior alveolar artery (enters mandibular foramen) artery to mylohyoid.
Where is Ethmoidal artery?
The anterior ethmoidal artery, is a branch of the ophthalmic artery in the orbit. It exits the orbit through the anterior ethmoidal foramen. The posterior ethmoidal artery is posterior to it.
What is artery ligation?
With a blood vessel the surgeon will clamp the vessel perpendicular to the axis of the artery or vein with a hemostat, then secure it by ligating it; i.e. using a piece of suture around it before dividing the structure and releasing the hemostat.
Where does the anterior ethmoidal artery come from?
The posterior and anterior ethmoidal arteries typically arise from the third segment of the ophthalmic artery and course through the medial orbit before passing through the posterior and anterior ethmoidal canals, respectively, into the ethmoid air cells.
What are the symptoms of a blocked artery in the neck?
- Sudden numbness or weakness in the face or limbs, often on only one side of the body.
- Sudden trouble speaking and understanding.
- Sudden trouble seeing in one or both eyes.
- Sudden dizziness or loss of balance.

- Shortness of breath. If your heart can’t pump enough blood to meet your body’s needs, you may develop shortness of breath or extreme fatigue with activity.
- Heart attack.
Can you feel a blocked artery in your neck?
Carotid artery disease often does not cause symptoms until the blockage or narrowing is severe. One sign may be a bruit (whooshing sound) that your doctor hears when listening to your artery with a stethoscope.
What does the sphenopalatine artery supply?
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 temporal artery located?
The superficial temporal artery is a terminal branch of the external carotid artery. It originates at the level of the neck of the mandible. After traversing the parotid gland, it runs superficially to the zygomatic process of the temporal bone.
Which artery is a branch of the third part of the maxillary artery?
The third maxillary artery segment branches into the posterior superior dental (alveolar) artery, infraorbital artery, descending palatine artery, sphenopalatine artery, pharyngeal artery, artery of the foramen rotundum, and artery of the pterygoid canal (Vidian artery) (Fig 3).
Where are posterior auricular lymph nodes?
The mastoid lymph nodes (retroauricular lymph nodes or posterior auricular glands) are a small group of lymph nodes, usually two in number, located just beneath the ear, on the mastoid insertion of the sternocleidomastoideus muscle, beneath the posterior auricular muscle.
What causes posterior auricular lymph nodes to swell?
An ear infection can cause lymph nodes in front of or behind the ears to swell. You might also have ear pain and fever. Ears can become infected when fluid builds up in them. This can happen when you have allergies, a sinus infection, or the common cold.
