Sutures for Dermatology — Skin Closure & Excision Repair Guide
Dermatologic surgery focuses on skin excision, Mohs micrographic surgery for skin cancer, and reconstructive closure using flaps and grafts. Because the surgical site is visible and cosmetic outcome is a primary concern, suture selection directly impacts patient satisfaction. Layered closure with buried deep dermal sutures followed by precise epidermal approximation is the foundation of dermatologic wound closure technique.
Key Suture Selection Considerations
Layered closure is fundamental — buried absorbable sutures in the deep dermis relieve tension on the wound edges before skin surface closure, reducing scar widening
Cosmetic outcome is the primary success metric — suture material, gauge, and technique all influence final scar appearance
Monofilament sutures minimize tissue reactivity and suture-track marks — this is critical for visible skin closures on the face, neck, and extremities
Suture removal timing varies by anatomic location — facial sutures are removed at 5-7 days, trunk at 10-14 days, extremities at 14-21 days to balance wound strength against suture marks
Absorbable subcuticular technique avoids suture marks entirely and eliminates the need for patient return for removal
Deep dermal (buried) suture strength duration should match the 60-90 day scar maturation period to prevent scar widening during collagen remodeling
Recommended Desmo Care Sutures
DesmoCryl
PGCL monofilament with 21-28 day support — the primary choice for subcuticular skin closure and buried deep dermal sutures in dermatologic surgery due to smooth tissue passage and minimal tissue reactivity
DesmoMid
Polypropylene monofilament — the standard for percutaneous (interrupted or running) skin closure where planned suture removal allows optimal timing based on anatomic location and wound tension
DesmoCryl Rapid
Fast-absorbing PGCL monofilament with 7-10 day support — ideal for epidermal approximation over buried dermal sutures, low-tension closures, and situations where patients cannot return for suture removal
DesmoPol
PDO monofilament with 180-day extended support — used for deep dermal buried sutures in high-tension closures (trunk, extremities) where prolonged support during the collagen remodeling phase prevents scar widening
Clinical Notes & Best Practices
The American Academy of Dermatology (AAD) and dermatologic surgery literature consistently support layered closure with buried absorbable sutures as the technique that produces the best cosmetic outcomes. Deep dermal sutures using absorbable monofilament (PGCL or PDO) should be placed with the knot buried to avoid palpable knots and suture extrusion. For Mohs micrographic surgery defect closure, flap and graft survival depends on precise tissue approximation without excessive tension — deep absorbable sutures offload tension from the surface closure. Percutaneous suture removal timing is location-dependent: face 5-7 days, scalp 7-10 days, trunk 10-14 days, extremities 14-21 days. Evidence supports that subcuticular absorbable closure produces equivalent cosmetic outcomes to percutaneous closure when combined with adequate buried dermal sutures, with the advantage of no suture removal visit.
Frequently Asked Questions
What suture is best for skin closure after Mohs surgery?
▼
Mohs surgery defect closure uses a layered approach: DesmoPol (PDO) or DesmoCryl (PGCL) in 4/0-5/0 for buried deep dermal sutures, followed by either DesmoCryl subcuticular closure or DesmoMid (polypropylene) percutaneous sutures in 5/0-6/0 for facial skin. The deep dermal sutures are the key to both wound strength and cosmetic outcome.
When should I use absorbable vs non-absorbable sutures for skin?
▼
Absorbable subcuticular sutures (DesmoCryl) are preferred when avoiding suture removal is important (pediatric patients, unreliable follow-up) or when cosmetic outcome is paramount. Non-absorbable percutaneous sutures (DesmoMid polypropylene) allow the surgeon to control removal timing for optimal results based on anatomic location.
What suture gauge should I use for facial skin closure?
▼
Facial skin closure typically uses 5/0-6/0 gauge sutures for surface closure and 4/0-5/0 for buried deep dermal sutures. Finer gauge sutures minimize tissue damage and produce less visible suture marks. DesmoCryl in 5/0 or DesmoMid in 5/0-6/0 are appropriate choices for facial skin.
How do buried dermal sutures improve cosmetic outcomes?
▼
Buried deep dermal sutures (DesmoCryl or DesmoPol) relieve tension on the wound edges before skin surface closure. This reduces scar widening during the 60-90 day collagen remodeling phase, eliminates dead space that could collect fluid, and allows surface sutures to be placed with minimal tension — producing a finer, less visible scar.
What is the role of fast-absorbing sutures in dermatology?
▼
DesmoCryl Rapid (fast-absorbing PGCL) with 7-10 day support is used for epidermal approximation over buried dermal sutures, low-tension facial closures, and patients who cannot return for suture removal. The rapid absorption eliminates suture track marks while the underlying buried dermal sutures provide the primary wound strength.
