Understanding Sutures in Cosmetic Eyelid Surgery: Materials, Techniques, and Best Practices

Introduction

Cosmetic eyelid surgery (blepharoplasty) requires meticulous attention to detail to achieve excellent aesthetic and functional outcomes. While much attention is given to surgical planning, incision placement, and tissue handling, one often overlooked aspect is the choice of suture material and technique. The eyelid is a unique structure—thin, mobile, and vascular—so selecting the appropriate suture plays a pivotal role in healing, scarring, patient comfort, and long-term aesthetic success.

This article explores the types of sutures used in cosmetic blepharoplasty, including absorbable vs. non-absorbable options, various closure techniques, and when one method is preferred over another.

1. The Role of Sutures in Eyelid Surgery

Sutures are used to:

• Approximate skin and deeper tissues precisely.

• Minimize tension to reduce scar formation.

• Promote proper healing of incisions.

• Prevent complications such as wound dehiscence or asymmetry.

Because the eyelid skin is the thinnest on the body (0.3–0.5 mm), it demands fine suture materials that allow for precise closure without causing track marks, inflammation, or unnecessary tissue reaction.

2. Suture Classification: Absorbable vs. Non-Absorbable

A. Absorbable Sutures

These sutures break down naturally over time through enzymatic degradation or hydrolysis, eliminating the need for removal.

Common absorbable sutures in eyelid surgery:

• Fast-absorbing gut: Natural, monofilament; absorbed in 5–7 days.

• Plain gut: Natural, monofilament; absorbed in 7–10 days.

• Vicryl (polyglactin 910): Synthetic, braided; absorbed in 2–3 weeks.

• Monocryl (poliglecaprone 25): Synthetic, monofilament; absorbed in 7–10 days.

Advantages:

• No need for suture removal (especially beneficial in anxious or pediatric patients).

• Less risk of suture-related inflammation over time.

• Useful for deeper layer closure (e.g., orbicularis or septum).

Disadvantages:

• May incite more local inflammation in some individuals.

• Timing of absorption can be unpredictable depending on tissue environment.

B. Non-Absorbable Sutures

These sutures remain in place until manually removed, typically within 5–7 days after surgery.

Common non-absorbable sutures in eyelid surgery:

• Nylon (Ethilon): Synthetic, monofilament.

• Prolene (polypropylene): Synthetic, monofilament.

• Silk: Natural, braided (rarely used in cosmetic eyelid surgery due to inflammation risk).

Advantages:

• Very low tissue reactivity, especially nylon and polypropylene.

• Provide excellent wound support and clean incision lines.

• Easier to remove without leaving residue or fragments.

Disadvantages:

• Require a follow-up visit for removal.

• Can cause “railroad track” marks if tied too tightly or left too long.

3. Suture Size and Handling

Sutures for eyelid skin are extremely fine, generally ranging from:

• 6-0 to 7-0 for skin closure

• 5-0 or 6-0 for deeper tissues like orbicularis or septum

Smaller suture diameters minimize trauma and reduce the risk of visible marks but require excellent technique and instruments for proper handling.

4. Techniques of Eyelid Closure

The method of closure can be as important as the material. Common eyelid suture techniques include:

A. Interrupted Sutures

• Each stitch is tied off individually.

• Offers precise tension control at each point.

• Commonly used in upper eyelid blepharoplasty.

• Easy to remove selectively if needed (e.g., if irritation occurs).

Suture example: 6-0 nylon or fast-absorbing gut in interrupted fashion.

B. Running Sutures

• One continuous stitch along the length of the incision.

• Faster placement and potentially more even tension distribution.

• May be harder to remove if embedded or if swelling occurs.

Suture example: 6-0 or 7-0 nylon in continuous fashion; sometimes used with Prolene for minimal reactivity.

C. Subcuticular or Buried Sutures

• Suture is placed beneath the skin surface, often absorbable.

• No visible suture on the skin (aesthetic advantage).

• Reduces risk of track marks or stitch-related pigmentation.

Suture example: 6-0 or 7-0 Monocryl or Vicryl for subcuticular closure.

Note: Risk of cyst formation or mild inflammation exists if knots are placed too superficially.

5. Specific Applications in Upper vs. Lower Eyelid Surgery

Upper Eyelid Blepharoplasty

• Incisions are placed in the natural eyelid crease.

• Skin is very thin but relatively forgiving.

• Both interrupted nylon and running fast-absorbing gut are commonly used.

• Some surgeons prefer Prolene for long incisions to reduce inflammation.

Lower Eyelid Blepharoplasty

Can be performed via:

• Transconjunctival approach (no skin incision)

• Subciliary (skin) approach

For skin incisions (e.g., in skin-muscle flap):

• 6-0 or 7-0 nylon in running or interrupted fashion is common.

• For subcuticular closure, Monocryl or Vicryl Rapide may be used.

• Deep sutures in orbicularis or canthal tendon may use 5-0 Vicryl.

Transconjunctival incisions typically require:

• 6-0 or 7-0 plain gut for mucosal closure (if any closure at all is done).

6. New and Emerging Trends

A. Barbed Sutures

Rarely used in eyelid surgery due to risk of irritation, but being explored in brow lifts and deeper facial work.

B. Fibrin Glue

In some advanced techniques, tissue adhesives are used to supplement or replace sutures in internal fixation or skin closure. Their use in cosmetic blepharoplasty is limited but growing in niche scenarios.

C. Knotless Techniques

Newer monofilament absorbable sutures can be placed with buried, knotless endings, reducing the chance of granulomas or stitch extrusion.

7. Surgeon Preferences and Customization

No single suture is ideal for every patient or every technique. Surgeons often develop strong preferences based on:

• Skin type (thick vs. thin, oily vs. dry)

• Tendency for hypertrophic scarring or pigmentation

• Patient age and healing potential

• History of allergic or inflammatory response

• Desired aesthetic outcome (e.g., scarless closure)

Some typical choices might include:

Situation	Preferred Suture	Technique
Upper lid skin	6-0 prolene or plain	Interrupted or running or subcuticular
Lower lid skin	6-0 prolene or fast-absorbing gut	Subcuticular or interrupted
Conjunctival closure	6-0 plain gut	Running
Deep orbicularis	5-0 Vicryl	Interrupted buried
Patient with anxiety over removal	Fast-absorbing gut	Interrupted

8. Suture Removal and Aftercare

Timing of suture removal:

• 5–7 days for most skin sutures.

• Earlier removal (e.g., day 4) if signs of irritation appear or to reduce track marks.

• Use of antibiotic ointment during the healing period helps keep sutures soft and reduce infection risk.

Instructions for patients:

• Avoid pulling or rubbing sutures.

• Keep the area clean and lubricated.

• Watch for signs of inflammation or granuloma formation.

9. Complications Related to Sutures

While rare, complications can include:

• Suture track marks: Caused by too-tight sutures or delayed removal.

• Stitch abscess or granuloma: More common with absorbable sutures placed too superficially.

• Suture cysts: Can develop months later; may require excision.

• Allergic reaction: Particularly with silk or braided materials (rare in modern practice).

Proper technique and patient education are key to minimizing these issues.

Conclusion

Suture selection in cosmetic eyelid surgery is both an art and a science. The right combination of material, size, and technique enhances healing, maintains eyelid contour, and minimizes scarring. Whether using non-absorbable nylon for precise control or fast-absorbing gut for convenience, the goal is always the same: a nearly invisible scar with a naturally rejuvenated eyelid.

Surgeons must tailor their choices to the patient’s anatomy, healing tendencies, and procedure type. When done thoughtfully, proper suture technique is a quiet but essential contributor to excellent aesthetic outcomes in blepharoplasty.
