The outer corner of the eye although a small anatomic detail is in fact very important for eyelid and eye protection as well as for the overall face appearance. When the lower lid sags out or is in an abnormal position, we may turn to canthoplasty which is a solution to restore support. In some cases also this procedure may also play a role in changing the shape or position of the outer eye corner.
Canthoplasty surgery is a procedure that involves the reshaping or tightening of structures at the canthus which is the point where the upper and lower eyelids come together. Most often we see this done at the lateral canthus at the outer corner of the eye. What technique is used depends on the patient’s lid anatomy and the cause of the issue.
What Is Canthoplasty?
Canthoplasty is a procedure which reconstructs or tightens canthal structures. The surgeon may also work with the lateral canthal tendon to improve lower eyelid support and position. Research reports the procedure to be useful for issues such as eyelid laxity, ectropion, entropion, retraction, and abnormal lateral canthal position.
A lateral canthoplasty is what is used for the outer aspect of the eye. As per the diagnosis which we are dealing with the doctor may do a repositioning or reconstruction of the support structures and secure them in a better place.
People at times put Canthopexy and canthoplasty in the same category which is a mistake. Although both processes support the outer lid they are in fact different. Canthopexy usually tightens and supports present structures which is a less in depth approach.Canthoplasty surgery includes more in your face alteration of the lateral canthal tendon. Research reports that canthopexy does better for mild lid laxity, for more severe cases a more radical reconstructive approach is required.
| Procedure | General Purpose | Common Approach |
| Canthoplasty | Reshapes or reconstructs the outer eyelid support | May involve tendon division, repositioning and fixation |
| Canthopexy | Supports or tightens the existing lateral canthus | Usually involves less extensive alteration |
| Lateral canthoplasty | Corrects or changes the outer corner of the eye | Focuses on the lateral canthal structures |
Why Is Canthoplasty Surgery Performed?
Doctors will put forward canthoplasty as a treatment for a lower lid that does not have enough support or which is in an abnormal position. It helps with eyelid laxity, ectropion, entropion, lower lid retraction, or lateral canthal dystopia. Also at times Lateral canthoplasty will be used in reconstructive or cosmetic lid work.
Some people go for canthoplasty surgery which is a reason. Also into the mix comes eye shape, eyelid tension, tear film health, past history of surgery, and the structure of the bone which all play a role in what we see as suitability. Thus an ophthalmologist or canthoplasty surgeon will look at the eyelids before they put forth a recommendation.
How Is the Canthoplasty Procedure Performed?
Before performing canthoplasty the surgeon will evaluate eyelid laxity, canthal position, eye prominence and the surrounding anatomy. This assessment determines which of canthopexy, lateral canthoplasty, or some other eyelid procedure is the best option.
During canthoplasty surgery the surgeon accesses the outer aspect of the eyelid via a precise incision. As to which technique is used the surgeon may release, shorten, reposition or reconstruct the lateral canthal tendon. The tissue is then secured to achieve proper eyelid tension and alignment.
A careful plan is required for a lateral canthoplasty as even small changes in that area may impact eyelid appearance and function.
Recovery After Canthoplasty
Recovery from canthoplasty is variable based on the type of surgery and if another eyelid procedure was done at the same time. Swelling, bruising, tenderness and temporary tightness in the outer area of the eye present during early healing.
Patients should follow what the surgeon says in terms of post op care, medicine and follow up visits. Also they should avoid rubbing or putting extra pressure on the healing eyelid. The final outcome post canthoplasty surgery may only present itself once the swelling has gone down and the tissues have healed.
| Recovery Stage | What a Patient May Notice |
| Early recovery | Swelling, bruising, mild discomfort or tightness |
| Following days | Gradual reduction in swelling and tenderness |
| Later healing | Eyelid position continues to settle |
| Follow-up period | Surgeon checks healing, symmetry and eyelid function |
What Are the Possible Risks of Canthoplasty?
Like any surgical procedure, canthoplasty has to be considered. They include infection, bleeding, swelling, scarring, asymmetry, irritation, dry eye symptoms, altered eyelid position, or an unsatisfactory cosmetic result. Some patients may have a recurrence of eyelid malposition which in turn may require more treatment. Also reported in the published research on the lateral canthoplasty are issues of temporary conjunctival swelling and at times the need for revision surgery.
The variation in risks associated with canthoplasty surgery is patient dependent. Thus it is important to do a careful assessment and appropriate surgical planning.
Conclusion
Canthoplasty is a procedure which does repair support and also improves the position of the outer eyelid in right selected patients. For Lateral canthoplasty we see that it may correct functional issues related to the lid and in some cases also address aesthetic concerns. But also it is important that this canthoplasty surgery be done after a careful study as the eyelids play a very key role in protecting the eye and in the maintenance of a healthy ocular surface.
If you see lower lid sagging, out turning, persistent irritation or a change in the position of the lid, see an experienced ophthalmologist. At ASG Eye Hospital we will evaluate the issue and determine which procedure is right for you for canthopexy, canthoplasty, or another treatment.
FAQs About Canthoplasty
1. Is canthoplasty the same as canthopexy?
No. Canthoplasty is for more in depth reconstruction or repositioning of canthal structures. Canthopexy at most tightens or secures present tissues. The choice between canthopexy and canthoplasty is based on eyelid laxity and anatomy.
2. What is lateral canthoplasty?
Lateral canthoplasty is a type of canthoplasty which we perform at the corner of the eye which is the outer aspect. It may improve lid support, correct malposition, or change the lateral canthal position.
3. Is canthoplasty surgery cosmetic or medical?
Canthoplasty also has two uses. It is performed by doctors to correct functional issues with the eyelid or to include as an element in certain aesthetic eyelid procedures.
4. How long does recovery take?
Recovery is different for each patient and is based on the type of canthoplasty,, the degree of correction and also any other procedures. Swelling and bruising usually improve over time, while full tissue recovery may take longer.
5. How do I know whether I need canthoplasty or canthopexy?
An eye specialist should assess the position of your eyelids, their laxity, and the surrounding anatomy. In some cases, mild laxity can be treated with canthopexy; more pronounced problems may call for canthoplasty.
