Facial symmetry and eye shape play a crucial role in overall aesthetics. One key feature influencing eye appearance is the canthal tilt—the angle between the inner and outer corners of the eye. A negative canthal tilt occurs when the outer corner (lateral canthus) sits lower than the inner corner (medial canthus), which can create a tired or aged look. This article explores the causes, effects, and correction options for negative canthal tilt.
What is a Negative Canthal Tilt?
The canthal tilt refers to the upward or downward angle of the eyes. It is measured by drawing an imaginary line between the inner and outer corners of the eye:
- Positive Canthal Tilt: The outer corner is higher than the inner corner, contributing to a youthful, alert appearance.
- Neutral Canthal Tilt: Both corners are aligned, creating a balanced look.
- Negative Canthal Tilt: The outer corner is lower than the inner corner, potentially giving the face a tired or droopy look.
Causes of Negative Canthal Tilt
Several factors contribute to a negative canthal tilt, including:
1. Genetics
Some individuals are naturally born with a negative canthal tilt due to their unique facial structure and bone development.
2. Aging
As we age, collagen loss and skin laxity cause sagging around the eyes, potentially leading to a downward tilt.
3. Weak Ligaments and Soft Tissue
The lateral canthal tendon can weaken over time, causing the outer corner of the eye to descend.
4. Poor Orbital Bone Structure
A recessed or underdeveloped orbital rim may fail to provide adequate support for the surrounding tissues, leading to a downward tilt.
5. Trauma or Surgery Complications
Accidental injuries or poorly executed blepharoplasty (eyelid surgery) can alter the natural canthal positioning.
Aesthetic and Functional Impact
1. Aesthetic Concerns
- Can create a sad, tired, or aged look.
- May disrupt overall facial harmony and attractiveness.
- Can influence perceived masculinity or femininity (higher canthal tilt is often associated with youthful femininity).
2. Functional Issues
- May lead to dry eyes if the eyelids do not close properly.
- Can cause eye irritation or excessive tearing due to improper eyelid support.
- In severe cases, it can contribute to eyelid malposition, affecting vision.
How to Correct a Negative Canthal Tilt
1. Non-Surgical Approaches
Facial Exercises
While limited in effectiveness, certain exercises may help strengthen the muscles around the eyes to provide better support.
Dermal Fillers
Strategic placement of hyaluronic acid fillers around the cheeks and under-eye area can provide subtle lifting effects, though results are temporary.
Botox (Botulinum Toxin)
Botox injections around the orbicularis oculi muscle can subtly lift the outer corners of the eyes.
Thread Lifting
A minimally invasive procedure that uses dissolvable threads to lift sagging tissue, offering temporary results.
2. Surgical Options
Canthoplasty
- A canthoplasty is a surgical procedure that reconstructs the lateral canthus by tightening and repositioning the lateral canthal tendon.
- Results are permanent and provide a youthful, alert appearance.
- Requires downtime and healing but offers the most dramatic improvement.
Canthopexy
- A less invasive alternative to canthoplasty, where the lateral canthus is secured without major reconstruction.
- Offers subtle lifting and improved eye shape.
- Recommended for those with mild to moderate sagging.
Lower Eyelid Surgery (Lower Blepharoplasty)
- Removes excess skin and tightens the lower eyelid to enhance eye shape and support.
- Can be combined with canthoplasty or canthopexy for optimal results.

Conclusion
A negative canthal tilt can impact both aesthetics and function, but various treatments—from non-invasive fillers to permanent surgical corrections—offer effective solutions. If you’re considering correction, consult with an experienced facial plastic surgeon to determine the best approach for your needs.
FAQs
Q: Can a negative canthal tilt be fixed naturally? A: While facial exercises and skincare may improve the surrounding area, significant correction usually requires medical intervention.
Q: How long do surgical results last? A: Procedures like canthoplasty and canthopexy provide long-lasting, often permanent results.
Q: Does a negative canthal tilt affect vision? A: In severe cases, eyelid laxity may cause functional issues like dry eyes or eyelid malposition.
Q: How much does canthoplasty cost? A: The cost varies based on location and surgeon expertise but typically ranges from $3,000 to $7,000.
Q: Is there downtime after surgical correction? A: Yes. Most patients experience swelling and bruising for 1-2 weeks, with full healing taking several months.
