Introduction to the Facial Artery
The facial artery is a key blood vessel in the face. It brings oxygen-rich blood to different parts of the face. Its complex path and many branches help ensure tissues get enough blood.
Starting from the external carotid artery, the facial artery travels through the face. It goes along the mandible, mouth, and nose. This path lets it supply blood to important facial structures.
| Facial Structure | Key Features |
|---|---|
| Lips and oral cavity | Supplied by labial arteries |
| Nose and nasal cavity | Perfused by lateral nasal and angular arteries |
| Muscles of facial expression | Receive blood supply via muscular branches |
The facial artery has many important branches. These include the submental, inferior and superior labial, lateral nasal, and angular arteries. These branches help the facial artery cover more of the face.
Doctors and surgeons need to know about the facial artery. It’s important for treating facial injuries, plastic surgery, and dental work. Its role in supplying blood to the face is vital for many medical and beauty treatments.
Anatomical Course of the Facial Artery
The facial artery is key in the blood flow to the face. It starts and ends in complex ways. Knowing its path is vital for doctors in plastic surgery, dermatology, and dentistry.
Origin and Proximal Segment
The facial artery begins from the external carotid artery, near the lingual artery. It goes deep to the submandibular gland. Then, it comes out from under the gland to the bottom of the jaw.
Tortuous Path along the Face
After reaching the jaw’s bottom, the artery winds its way up. It moves forward and up, crossing the jaw’s edge. It goes deep to muscles and near the mouth and nose.
| Segment | Location | Key Landmarks |
|---|---|---|
| Proximal | Origin to mandibular margin | External carotid artery, submandibular gland |
| Middle | Mandibular margin to angle of mouth | Platysma muscle, risorius |
| Distal | Angle of mouth to medial canthalus | Nose, medial canthalus |
Terminal Branches and Anastomoses
The facial artery ends as the angular artery near the eye’s corner. It connects with other arteries along the way. These connections help keep the face well supplied with blood, even if the main artery is blocked.
Branches of the Facial Artery
The facial artery runs through the maxillofacial vasculature. It gives off several key branches. These branches are vital for the blood supply of facial structures. Knowing about these branches helps us understand the face’s anatomy and its clinical importance.
Ascending Palatine Artery
The ascending palatine artery starts near the facial artery’s beginning. It goes up between the stylopharyngeus and styloglossus muscles. It supplies the soft palate, tonsils, and the pharyngeal wall.
Submental Artery
The submental artery branches off the facial artery at the submandibular gland. It moves forward under the jaw. It supplies the floor of the mouth, submandibular gland, and the skin above.
Inferior and Superior Labial Arteries
The inferior and superior labial arteries come from the facial artery. They run along the edges of the lower and upper lips. They supply the lips and the mucosa inside them, and they connect with their opposite sides.
| Artery | Location | Structures Supplied |
|---|---|---|
| Inferior Labial | Lower lip margin | Lower lip, labial mucosa |
| Superior Labial | Upper lip margin | Upper lip, labial mucosa |
Lateral Nasal Artery
The lateral nasal artery branches off the facial artery near the nose. It supplies the ala and dorsum of the nose. It also connects with the dorsal nasal branch of the ophthalmic artery.
Angular Artery
The angular artery is the facial artery’s last branch. It goes up alongside the nose to the eye’s medial corner. It supplies the lacrimal sac and connects with the dorsal nasal artery.
Understanding the facial artery’s branching is key to its blood supply to the maxillofacial vasculature. This knowledge is vital in managing facial trauma, plastic surgery, and other face-related clinical situations.
Facial Artery Variations and Anomalies
The facial artery usually follows a set path, but it can vary. These changes are important for doctors, like those in craniofacial surgery. They help make sure surgeries are safe and work well.
One common variation is when the left and right facial arteries are not the same. Their start, branching, or end can differ. Sometimes, the facial artery comes straight from the external carotid artery. Other times, it joins with the lingual artery at the start.
How the facial artery branches can also change its area of supply. For example, the submental artery might start from the lingual artery instead of the facial artery. The lateral nasal artery might not exist or might get its blood from other arteries.
Some facial artery issues can affect treatment. For instance, if the facial artery is too small or missing, other arteries might take over. This includes the transverse facial artery or the infraorbital artery.
Knowing about facial artery variations is key for surgery planning. Tests like angiography or Doppler ultrasonography can show these differences. This helps doctors make better choices for surgery.
Understanding facial artery variations helps doctors plan better treatments. This reduces risks and improves results for patients in craniofacial surgeries.
Blood Supply to Facial Structures
The facial artery is key in bringing blood to the face’s structures. It helps keep them nourished and working right. It’s part of the face’s blood network, reaching the lips, mouth, nose, and facial muscles.
The lips and mouth get their blood from the facial artery’s branches. These arteries connect with others, making sure the lips and mouth heal well.
The nose and nasal area get blood from the facial artery’s ends. This blood is vital for the nose’s health, helping in treating nosebleeds and surgery.
The facial muscles, which show our emotions, also rely on the facial artery. It feeds the muscles around the mouth and nose. Below is a list of facial parts and their blood sources:
| Facial Structure | Arterial Supply |
|---|---|
| Lips | Superior and inferior labial arteries |
| Oral cavity | Labial arteries, ascending palatine artery |
| Nose (external) | Lateral nasal artery, angular artery |
| Nasal cavity | Lateral nasal artery, branches of sphenopalatine artery |
| Muscles of facial expression | Labial arteries, angular artery |
Knowing how blood reaches the face is very important. It helps in plastic surgery and treating facial injuries. The face’s blood system, led by the facial artery, makes surgery more precise and successful.
Clinical Significance of the Facial Artery
The facial artery is very important because it supplies blood to the face. It’s a key part in many medical and surgical situations. This includes managing facial trauma and doing reconstructive surgery.

To lower the risk of injecting into the artery, doctors use special techniques. They check before injecting and use small amounts of filler in risky spots. They also prefer blunt-tipped cannulas over sharp needles to avoid hitting the artery.
In face lifts and fat grafting, the facial artery is a key landmark. Keeping it safe during surgery is important. It helps the skin and tissues get enough blood, which aids in healing and reduces risks.
Knowing the face’s blood vessels, like the facial artery, is critical for safe and effective beauty treatments. Doctors need to keep learning about the facial artery and use the latest safe methods. This ensures they can give their patients the best care.
Imaging and Evaluation of the Facial Artery
The facial artery is key for blood supply to the face. Advanced imaging like angiography and Doppler ultrasonography are used to study it. These methods help doctors see the artery’s details and plan treatments.
Angiography Techniques
Angiography uses contrast media to see blood vessels. For the facial artery, there are a few ways to do it:
| Technique | Description |
|---|---|
| Catheter Angiography | Invasive procedure involving catheter insertion and contrast injection |
| CT Angiography (CTA) | Non-invasive imaging using computed tomography and contrast media |
| MR Angiography (MRA) | Non-invasive imaging using magnetic resonance technology |
These methods give clear images of the facial artery. Doctors can see its shape, size, and any problems like blockages or aneurysms.
Doppler Ultrasonography
Doppler ultrasonography uses sound waves to check blood flow. It’s great for the facial artery because it’s:
- Non-invasive, so no need for surgery
- Can see blood flow in real-time
- Can spot problems like blockages
- Doesn’t use harmful radiation or dyes
Doppler ultrasonography is key for checking if the facial artery is working right. It helps find issues like blood clots or abnormal connections. It’s also good for checking how well treatments are working.
Using both angiography and Doppler ultrasonography gives a full view of the facial artery. These tools help doctors find and fix problems. They make sure patients get the best care for their facial artery issues.
Facial Artery Pathology and Disorders
The facial artery is a key blood vessel in the face. It can face various health issues and disorders. These problems can cause serious complications and need quick diagnosis and treatment.
Healthcare experts must know about common facial artery pathologies. This knowledge is vital for treating craniofacial disorders.
Aneurysms and Pseudoaneurysms
Aneurysms of the facial artery are rare but can happen due to injury, infection, or birth defects. These aneurysms feel like pulsating lumps and might hurt or press on nearby tissues. Pseudoaneurysms, caused by damage to the artery wall, can also occur, often after facial injuries or surgery.
Doctors use imaging like angiography or Doppler ultrasonography to find these issues. Treatment might include surgery, endovascular embolization, or injecting thrombin.
Arteriovenous Malformations
Arteriovenous malformations (AVMs) are birth defects of the facial artery. They have abnormal connections between arteries and veins, skipping the capillary bed. These malformations can lead to cosmetic issues, bleeding, or heart problems.
Angiography confirms the presence of AVMs by showing the abnormal connections. Treatment depends on the size and location of the malformation. It might include embolization, surgery, or a mix of both.
Thrombosis and Embolism
Thrombosis of the facial artery is rare but serious. It can cause facial structures to not get enough blood. It might be due to local issues like compression or inflammation, or systemic problems like blood clotting disorders.
Embolism to the facial artery can come from elsewhere, like the heart or carotid arteries. It can cause sudden facial pain and skin changes. Quick diagnosis and treatment with anticoagulation or thrombolysis are key to avoid tissue damage and long-term effects.
Understanding facial artery pathologies and disorders is critical. It requires knowledge of facial vascular anatomy and the risks of vascular problems. Teamwork between radiologists, vascular surgeons, and other specialists is essential for the best patient care in these complex cases.
Facial Artery in Dental and Oral Surgery
The facial artery is key in the blood supply of the mouth. It’s very important in dental and oral surgeries. It feeds the teeth, gums, and soft tissues around them. Dental and oral surgeons need to know a lot about it to do their jobs well.
When doing surgeries like tooth extractions or implant placements, the facial artery is very important. If it gets hurt, it can cause a lot of bleeding. To avoid this, surgeons use precise incisions and hemostatic agents.
| Procedure | Facial Artery Consideration |

The facial artery’s pulse is also useful for giving local anesthesia. By feeling the pulse, dental workers can find the right spot for the injection. This makes the procedure safer for the patient.
Comparison with Other Craniofacial Arteries
The facial artery is a key blood supplier to the face. But it’s not alone. The maxillary artery and the superficial temporal artery also play important roles. Knowing how these arteries differ and are similar helps us understand the face and head’s blood flow.
Maxillary Artery
The maxillary artery comes from the external carotid artery. It brings blood to the face’s deep areas, like teeth, gums, and the maxillary sinus. Its path is more complex than the facial artery’s, going through several spaces. It branches out to form a detailed network of blood vessels in the face.
Superficial Temporal Artery
The superficial temporal artery is also from the external carotid artery. It runs along the head’s side, supplying blood to the scalp, forehead, and temporal area. It’s easy to feel because it’s close to the skin. Unlike the facial artery, it mainly serves the head’s sides and top.
By looking at the facial artery alongside the maxillary and superficial temporal arteries, we get a better picture of face and head blood flow. Each artery has its own path and branches, making sure all parts of the face and head get enough blood. This is key for doctors working on facial injuries, surgeries, or other head and neck procedures.
