Canthopexy surgery, also known as canthal suspension, is a specialized type of facial plastic surgery that focuses on the outer corners of the eyes, known as the lateral canthi. This surgery may not be as well – known as some other facial procedures like facelifts or rhinoplasties, but it plays a crucial role in enhancing the appearance and functionality of the eyes. Understanding what canthopexy surgery entails is important for those considering this procedure to address various eye – related aesthetic or functional concerns.
The Basics of the Canthi
Anatomy of the Canthi
Before delving into canthopexy surgery, it’s essential to understand the anatomy of the canthi. The canthi are the corners where the upper and lower eyelids meet. The lateral canthus, which is the focus of canthopexy surgery, is the outer corner of the eye. This area is supported by a complex structure of ligaments, muscles, and connective tissues.
The lateral canthal tendon is a key component. It attaches the outer edges of the upper and lower eyelids to the lateral orbital rim, the bony structure around the eye socket. This tendon helps maintain the position and shape of the outer corner of the eye. As we age or due to certain medical conditions, the tissues in this area can weaken, leading to changes in the appearance and function of the lateral canthus.
Function of the Canthi
The canthi serve several important functions. They help in the proper drainage of tears from the eyes. The lacrimal drainage system starts near the inner corners of the eyes, but the position of the lateral canthi also influences the overall tear flow and drainage. If the canthi are not in the correct position, it can lead to problems such as epiphora, which is excessive tearing.
Aesthetically, the canthi play a significant role in the overall shape and appearance of the eyes. A well – positioned lateral canthus gives the eyes a more youthful, alert, and symmetric look. Changes in the canthal position can make the eyes appear droopy, tired, or asymmetrical.
Reasons for Canthopexy Surgery
Aesthetic Reasons
Anti – aging: One of the most common aesthetic reasons for canthopexy surgery is to combat the signs of aging. As we age, the skin loses its elasticity, and the tissues around the eyes, including the lateral canthal tendon, can weaken. This can cause the outer corners of the eyes to droop, creating a tired or sad appearance. Canthopexy can lift and reposition the lateral canthus, giving the eyes a more youthful and refreshed look.
Correcting Asymmetry: Some people are born with or develop an asymmetry in the position of their lateral canthi. This can be a source of self – consciousness. Canthopexy can be used to correct this asymmetry, creating a more balanced and harmonious appearance of the eyes.
Functional Reasons
Treating Ectropion or Entropion: Ectropion is a condition where the lower eyelid turns outward, while entropion is when the lower eyelid turns inward. These conditions can be caused by a variety of factors, including aging, trauma, or certain medical conditions. In some cases, canthopexy can be part of the treatment plan. By repositioning the lateral canthus, the tension on the eyelids can be adjusted, helping to correct the abnormal eyelid position.
Improving Tear Drainage: As mentioned earlier, the position of the canthi affects tear drainage. If the lateral canthus is not in the proper position, it can disrupt the normal flow of tears, leading to excessive tearing or dry eyes. Canthopexy can correct the canthal position, improving tear drainage and alleviating these symptoms.
The Canthopexy Surgery Procedure
Pre – operative Preparation
Before the canthopexy surgery, a thorough consultation with a qualified plastic surgeon is essential. The surgeon will discuss the patient’s goals, whether they are aesthetic or functional. A detailed medical history will be taken, including any previous eye surgeries, medical conditions, and medications the patient is taking.
The surgeon will also perform a physical examination of the eyes and the surrounding area. This may include assessing the position of the canthi, the strength of the lateral canthal tendon, and the overall condition of the eyelids. In some cases, additional tests such as a tear function test may be ordered to evaluate the patient’s tear production and drainage.
Anesthesia
Canthopexy surgery is typically performed under local anesthesia with sedation. Local anesthesia numbs the area around the eyes, while sedation helps the patient relax during the procedure. In some cases, general anesthesia may be used, especially if the patient has a high level of anxiety or if the surgery is more complex and combined with other procedures.
Surgical Steps
Incision: The surgeon makes a small incision in the outer corner of the eye, usually in the natural crease or along the hairline, depending on the approach. This incision allows access to the lateral canthal tendon and the surrounding tissues.
Tendon Adjustment: The lateral canthal tendon is then identified. If the goal is to lift the canthus, the tendon may be tightened or re – attached to a higher position on the lateral orbital rim. In some cases, a small piece of the tendon may be removed to adjust the tension.
Suspension: To ensure the long – term stability of the new canthal position, the surgeon may use sutures or other materials to suspend the canthus in its new position. These sutures are carefully placed to provide the right amount of support and lift.
Closure: Once the canthal position is adjusted and stabilized, the incision is closed with fine sutures. The sutures used are usually very small and dissolvable, which means they will gradually break down and be absorbed by the body over time, reducing the need for suture removal.
Post – operative Care
Immediate Post – operative Period
After the surgery, the patient will be monitored in a recovery area for a short time. The eyes will be covered with a dressing to protect the surgical site. The patient may experience some pain, swelling, and bruising around the eyes. Pain medications will be prescribed to manage the pain, and cold compresses may be recommended to reduce swelling.
Recovery at Home
Once discharged, the patient will need to follow specific post – operative instructions. This includes keeping the surgical area clean and dry. The doctor may provide a mild cleanser to gently clean the area around the eyes. Avoiding touching or rubbing the eyes is crucial to prevent infection and disruption of the healing process.
The patient may also be advised to sleep with the head elevated, usually on a few pillows. This helps reduce swelling by allowing gravity to assist in draining the excess fluids from the area.
Follow – up Appointments
Regular follow – up appointments with the surgeon are essential. These appointments usually start a few days after the surgery and continue over the next few weeks and months. During these appointments, the surgeon will check the healing progress of the incision, the position of the canthus, and the overall results of the surgery.
The surgeon may also provide advice on scar management, as the incision may leave a small scar. In most cases, the scar is well – hidden in the natural crease or hairline and fades over time. However, proper scar – care techniques, such as using silicone – based scar gels, can help minimize the appearance of the scar.
Potential Complications
Infection
Infection is a potential complication of any surgical procedure, including canthopexy. Signs of infection may include redness, swelling, pain, warmth at the surgical site, and discharge. If an infection occurs, it usually happens within the first few weeks after the surgery. Treatment typically involves antibiotics, and in severe cases, additional surgical intervention may be required.
Scarring
Although the incisions in canthopexy are small, there is still a risk of scarring. The appearance of the scar can be influenced by factors such as the patient’s skin type, the surgical technique used, and how well the incision is cared for during the healing process. In some cases, the scar may be more prominent than expected, and additional treatments such as laser therapy or scar – revision surgery may be considered.
Over – correction or Under – correction
There is a risk of over – correction or under – correction of the canthal position. Over – correction can result in an unnatural, “cat – eye” appearance, while under – correction may not achieve the desired aesthetic or functional results. A skilled surgeon will take great care to ensure the correct amount of lift and adjustment, but in some cases, a secondary procedure may be necessary to achieve the optimal outcome.
Results and Recovery Time
Immediate Results
Immediately after the surgery, the patient may notice a change in the position of the lateral canthus. However, the area will be swollen and bruised, which can affect the overall appearance. The full effect of the surgery may not be visible at this stage.
Long – term Results
As the swelling and bruising subside, usually within 1 – 2 weeks, the final results of the canthopexy surgery become more apparent. The eyes should appear more lifted, and any asymmetry or drooping should be improved. The results are generally long – lasting, but it’s important to note that the natural aging process will continue, and over time, some changes in the canthal position may still occur.
Recovery Time
The recovery time for canthopexy surgery is relatively short compared to some other facial plastic surgeries. Most patients can return to their normal daily activities, such as work and light social activities, within 1 – 2 weeks. However, more strenuous activities, such as exercise and heavy lifting, should be avoided for a few more weeks to allow the surgical site to fully heal.
Who is a Good Candidate for Canthopexy Surgery
Age and Health
Canthopexy surgery can be suitable for a wide range of ages. For younger patients, it may be used to correct congenital or acquired asymmetry. In older patients, it is often used as part of an anti – aging treatment plan. However, the patient should be in good overall health. Certain medical conditions, such as uncontrolled diabetes or high blood pressure, may increase the risk of complications and may need to be managed before considering the surgery.
Realistic Expectations
A good candidate for canthopexy surgery is someone who has realistic expectations. They should understand the goals and limitations of the surgery and be aware that it is not a one – size – fits – all solution. The surgery can improve the appearance and function of the eyes, but it cannot completely stop the aging process or create a completely different eye shape.
Conclusion
Canthopexy surgery is a specialized facial plastic surgery that can have a significant impact on the appearance and function of the eyes. Whether it’s for aesthetic reasons, such as achieving a more youthful look, or for functional purposes, like treating eyelid malpositions or improving tear drainage, canthopexy can offer effective solutions.
Understanding the procedure, the post – operative care, and the potential complications is crucial for anyone considering this surgery. By choosing a qualified and experienced plastic surgeon and having realistic expectations, patients can achieve satisfying results and enhance their overall quality of life. If you have concerns about the appearance or function of your lateral canthi, a consultation with a plastic surgeon can help you determine if canthopexy surgery is the right option for you.
