Understanding the Tear Trough Anatomy

Facial Structure & Underlying Vessels

Understanding the anatomy of the tear trough, facial structure, and underlying vessels is crucial for safe and effective filler injections in this delicate area.

The tear trough is the hollowed-out area beneath the eye, between the lower eyelid and the inner corner of the eyebrow. It’s formed by a combination of factors:

  • Facial fat loss: As we age, the natural fat pads under the eyes can descend, causing the tear trough to become more prominent.

  • Thinning skin: The skin around the eyes is naturally thinner than other areas, making the underlying structure more visible.

  • Bone anatomy: The shape and prominence of the orbital bone can also influence the appearance of the tear trough.

Underlying Vessels:

What is the danger zone for tear trough fillers?

Several significant blood vessels run through the tear trough area, making it crucial to be aware of their location during injections. These include:

  • Superficial Temporal Artery (STA): This artery supplies blood to the forehead and temples and runs along the temporal ridge.

  • Facial Vein: A major vein that drains blood from the face and passes through the tear trough area. It lies closer to the skin surface than the artery.

  • Infraorbital Artery: Located beneath the orbit bone, this artery supplies blood to the lower eyelids and surrounding tissues.

Danger Zone:

The danger zone for tear trough fillers is a specific region within the tear trough where injecting filler too deeply can risk arterial occlusion (blockage) due to its proximity to major blood vessels. This area typically lies between the medial canthal tendon and the orbital bone, extending slightly inferiorly.

Injecting filler into this danger zone can cause complications like:

  • Arterial occlusion: This is a serious complication where blood flow to an artery is blocked, potentially leading to tissue death (necrosis) if not immediately treated.

  • Filler migration: Filler may spread beyond the intended area, causing asymmetry or other aesthetic issues.

Experience and Knowledge Are Crucial:

Performing tear trough filler injections safely requires extensive knowledge of facial anatomy, proper injection techniques, and careful patient selection. Choosing a qualified and experienced injector is essential to minimize risks and achieve natural-looking results.

Blood Supply to the Area

The tear trough, also known as the “under-eye hollow,” is a depression located between the inner corner of the eye (medial canthus) and the cheekbone. Understanding the anatomy and blood supply of this delicate area is crucial for safe and effective tear trough filler injections.

The tear trough is formed by several structures, including:

  • Orbital septum: A thin sheet of tissue that separates the orbital contents from the surrounding soft tissues.

  • Orbicularis oculi muscle: The muscle responsible for closing the eyelids. Its lower fibers contribute to the contour of the tear trough.

  • Infraorbital fat pad: A collection of fatty tissue located below the eye socket. This pad contributes to the volume and fullness of the under-eye area.

  • Skin:** The skin in this region is thin and delicate, making it susceptible to bruising and complications from injections.


The tear trough receives its blood supply primarily from:

  • Facial artery: The main artery supplying the face. It branches into smaller vessels that reach the lower eyelid and surrounding tissues.

  • Inferior ophthalmic artery: A branch of the ophthalmic artery, which provides blood to the eye and surrounding structures.

These vessels are particularly concentrated in the danger zone**, a region located just below the orbital rim and above the cheekbone. This area is at higher risk for complications, such as bleeding, hematomas (blood clots under the skin), and vascular occlusion (blockage of blood flow) during injections.

Understanding the complex anatomy and blood supply of the tear trough is crucial for practitioners to safely and effectively administer tear trough fillers. Careful consideration of injection depth, volume, and technique is essential to minimize the risk of complications in this delicate area.

Risks Associated with Improper Injections

Blind Injection Technique Dangers

Improper injections, particularly those using a technique known as “blind injection,” pose significant risks when it comes to aesthetic procedures like tear trough filler treatment.

Blind injection refers to injecting dermal fillers without proper visualization of the target area. This means the injector relies solely on estimated anatomical landmarks rather than direct visual confirmation of needle placement.

The dangers associated with this technique are manifold and can lead to a range of undesirable outcomes:

**1. Vascular Occlusion (Arterial/Venous):** A major risk is injecting filler into or near blood vessels. This can obstruct blood flow, leading to tissue ischemia (lack of oxygen) and necrosis (tissue death). In severe cases, this can result in permanent damage or even loss of vision.

2. Filler Migration:** Injecting without proper visualization increases the risk of filler migrating from its intended location. This can create lumps, bumps, or an unnatural appearance.

3. Nerve Injury: The tear trough area is densely populated with nerves. Blind injections can inadvertently damage these nerves, leading to numbness, tingling, pain, or weakness in the eyelid and surrounding areas.

4. Infection: Any injection carries a risk of infection, but improper technique increases this likelihood. Using unsterile equipment or not following proper hygiene protocols can introduce bacteria into the bloodstream, potentially causing serious complications.

**5. Overfilling/Asymmetry:** Blind injections make it difficult to accurately assess the amount of filler needed and achieve balanced results on both sides. Overfilling can lead to an unnatural, bulging appearance, while asymmetry can create an unbalanced facial profile.

To mitigate these risks, it is crucial to choose a qualified and experienced injector who utilizes imaging techniques (like ultrasound) to visualize the injection site and ensure accurate placement. This minimizes the chances of complications and maximizes the safety and effectiveness of tear trough filler treatment.

Potential Complications: Vascular Occlusion

Improper injections, particularly in delicate areas like the tear troughs, carry significant risks due to the proximity of vital structures.

A major concern is vascular occlusion, which occurs when a blood vessel becomes blocked by a foreign substance. In the context of tear trough fillers, this can happen if the filler material enters an artery, leading to a potentially life-threatening complication known as an arterial thrombosis or stroke.

Here’s a breakdown of the risks and complications associated with vascular occlusion:

Risk Factors:

Improper Injection Technique:** Injecting too deeply, at an incorrect angle, or using excessive force increases the risk of hitting a blood vessel.

• **Filler Type:** Certain filler types may be more likely to cause vascular occlusion than others. Hyaluronic acid fillers are generally considered safer than collagen-based fillers.

Patient Factors: Individuals with pre-existing conditions like hypertension, diabetes, or clotting disorders are at higher risk for complications.

Complications of Vascular Occlusion:**

• **Ischemia:** A blockage in a blood vessel can restrict blood flow to surrounding tissues. This leads to ischemia, which can cause tissue damage and necrosis (death).

Arterial Thrombosis:** A clot forms within an artery, potentially leading to stroke or other serious cardiovascular events.

• **Blindness: If a blood vessel in the eye is affected, it can lead to vision loss or blindness.

Recognizing and Managing Vascular Occlusion:**

Prompt recognition and management are crucial for minimizing damage. Signs and symptoms can include:

• Pain at the injection site

• Swelling

• Redness

• Blurred vision

• Numbness or tingling in the face

Immediate medical attention is necessary if any of these symptoms develop.

Treatment for vascular occlusion may include medication to dissolve blood clots, surgery to remove a clot, or tissue reconstruction if necrosis has occurred.

To minimize risks associated with tear trough fillers and other injections, it’s essential to choose a qualified and experienced injector. Ask questions about their technique, experience with vascular complications, and the type of filler they use.

Be sure to disclose any medical conditions or medications you are taking, and carefully review the potential risks and benefits of the procedure before agreeing to treatment.

Minimizing Risks and Ensuring Safe Treatment

Choosing a Qualified Injector

Minimizing risks and ensuring safe treatment when considering tear trough fillers begins with meticulous research and careful selection of a qualified injector.

Choosing an experienced and reputable professional is paramount to achieving desired results while mitigating potential complications.

Here’s what to consider:

1. **Board Certification:** Opt for a physician board-certified in a relevant specialty, such as dermatology, plastic surgery, or otolaryngology (ENT). This certification signifies rigorous training and adherence to ethical standards.

2. **Experience with Tear Trough Fillers:** Inquire about the injector’s experience specifically with tear trough injections. A skilled injector will have a deep understanding of facial anatomy, product characteristics, and the nuances of this delicate area.

3. **Before & After Photos:** Request to see before-and-after photos of patients who have undergone similar procedures. This allows you to assess the injector’s aesthetic judgment and technical proficiency.

4. **Consultation Thoroughness:** A comprehensive consultation is essential. The injector should take the time to understand your concerns, medical history, and desired outcome. They should also discuss potential risks and complications openly and honestly.

5. **Facility Standards:** Ensure the injection facility meets appropriate hygiene and safety standards. Look for a clean, well-maintained environment with sterilized equipment.

Remember, choosing the right injector is a crucial step in minimizing risks and ensuring safe treatment when considering tear trough fillers.

Pre-Treatment Consultation and Evaluation

Minimizing risks and ensuring safe treatment starts long before any filler is injected. A thorough pre-treatment consultation and evaluation are crucial steps in determining if a patient is a suitable candidate for tear trough filler, identifying potential complications, and setting realistic expectations.

A comprehensive medical history review should be conducted, including questions about allergies, previous cosmetic procedures, medications (including supplements), bleeding disorders, and any history of skin or vascular conditions. This information helps identify potential contraindications or risks specific to the patient.

A detailed physical examination is equally important. The practitioner should carefully assess the patient’s anatomy, including the tear trough area, surrounding tissues, and facial symmetry. They should look for signs of vascular compromise, such as visible blood vessels close to the surface, which can increase the risk of complications if injected.

Open communication is key during this consultation. The practitioner should thoroughly explain the procedure, potential risks and benefits, expected outcomes, and realistic expectations. They should also address any patient concerns or questions in a clear and understandable manner.

The chosen filler should be carefully selected based on the patient’s individual needs and goals, as well as their skin type and anatomy. It is crucial to use hyaluronic acid-based fillers specifically designed for tear trough treatment, as these are less likely to cause complications. The practitioner should have extensive experience in using these fillers for this specific purpose.

Pre-treatment instructions, such as avoiding aspirin or blood thinners for a few days prior to the procedure, should be provided to minimize bleeding risk. Patients should also be advised on post-procedure care, including cold compresses and avoiding strenuous activity, to optimize healing and reduce swelling.
