What are cosmetic canthoplasty and canthopexy?
Cosmetic canthoplasty and canthopexy are surgical procedures that modify the outer corner of the eye, known as the lateral canthus, to improve its shape, definition, and position. These procedures can lift a downward-slanting outer corner, tighten a lax or loose lower eyelid, or create a more almond-shaped eye contour for patients seeking a refined, aesthetically balanced appearance.
The lateral canthus plays a significant role in the overall shape and expressiveness of the eye. When this area loses tone with age or when the natural anatomy of the outer corner does not align with a patient's aesthetic goals, canthoplasty and canthopexy offer precise, targeted correction.
While these same techniques are used in functional eyelid surgery to treat structural eyelid conditions such as ectropion or entropion, cosmetic canthoplasty and canthopexy are performed solely to enhance appearance and are not typically covered by insurance.
What is the difference between cosmetic canthoplasty and canthopexy?
Both procedures address the lateral canthal tendon, the tissue that anchors the outer corner of the eyelid to the orbital rim, but they differ in their extent and approach:
- Canthopexy is a less invasive procedure that tightens and reinforces the existing canthal tendon without detaching it. It is best suited for patients with mild laxity or those seeking subtle repositioning and refinement of the outer corner.
- Canthoplasty is a more involved procedure in which the canthal tendon is detached, reshaped, and reattached to the orbital rim at a new position. It is used when more significant reshaping or lifting of the outer corner is desired, or when canthopexy alone would not achieve the patient's goals.
Your surgeon will determine which approach is most appropriate based on your anatomy and the outcome you are looking to achieve.
Who is a candidate for cosmetic canthoplasty or canthopexy?
Cosmetic canthoplasty or canthopexy may be appropriate for patients who:
- Have a downward-slanting outer corner of the eye they would like lifted or repositioned
- Have laxity or looseness at the outer corner of the eyelid that affects the overall shape of the eye
- Are seeking a more defined, almond-shaped eye contour
- Have asymmetry between the two outer corners of the eyes
A thorough consultation with your surgeon will determine which procedure is best suited to your anatomy and goals.
What should I expect during cosmetic canthoplasty or canthopexy?
Prior to surgery, you will meet with your oculofacial plastic surgeon for a detailed consultation. During this appointment, your surgeon will:
- Evaluate the position, shape, and laxity of the outer corner of the eye
- Assess overall eyelid anatomy and symmetry
- Review your medical history, current medications, and any supplements that may need to be paused before surgery
- Discuss your aesthetic goals and the surgical approach best suited to your anatomy
- Take photographs for surgical planning and records
- Answer any questions you have about the procedure and recovery
Cosmetic canthoplasty and canthopexy are performed as outpatient procedures under local anesthesia, and patients go home the same day.
Canthopexy is performed through a small incision at the outer corner of the eye. The existing canthal tendon is identified and secured in a tightened position using sutures, reinforcing the support of the outer corner without altering its fundamental structure.
Canthoplasty involves a similar incision at the outer corner of the eye, through which the canthal tendon is carefully detached from the orbital rim. The tendon is then trimmed, reshaped, and reattached at a new position that achieves the desired contour and lift. Fine sutures are used to close the incision at the conclusion of the procedure.
Both procedures typically take between 30 and 60 minutes to complete. When performed in combination with other eyelid procedures such as blepharoplasty or ptosis repair, the total operative time will be longer.
What should I expect after cosmetic canthoplasty or canthopexy?
Recovery from cosmetic canthoplasty and canthopexy is generally well tolerated. Most patients are able to return to light daily activities within a few days, with full healing taking several weeks.
In the first several days following surgery, it is normal to experience:
- Swelling and bruising at the outer corner of the eye
- Mild discomfort or tightness in the treated area
- Temporary changes in tear drainage or watery eyes as the eyelid heals
- Sensitivity to light
Sutures are typically removed within one week of surgery. Initial swelling at the outer corner of the eye resolves within the first one to two weeks, with final shape and position continuing to refine over the following weeks as healing progresses.
What are the risks of cosmetic canthoplasty or canthopexy?
Cosmetic canthoplasty and canthopexy are well-established procedures with a high rate of patient satisfaction. As with any surgical procedure, there are potential risks to be aware of:
- Bleeding or hematoma
- Infection
- Scarring at the outer corner of the eye
- Asymmetry between the two sides
- Overcorrection resulting in an unnaturally tight or elevated outer corner
- Undercorrection requiring revision surgery
- Temporary or permanent changes in sensation around the outer corner of the eye
- Changes in tear drainage or dry eye symptoms
- Recurrence of laxity over time as tissue continues to age
The shape of the outer corner of the eye has a significant impact on the overall appearance and expressiveness of the face. Whether the goal is to lift a downward-slanting corner, tighten lax tissue, or refine the contour of the eye, cosmetic canthoplasty and canthopexy offer precise, lasting results.
