Flap Surgery

Published with the inputs from Dr Krishna Kumar K S, Senior Consultant & Chief, Plastic, Aesthetic And Reconstructive Surgery, Baby Memorial Hospitals- Kozhikode

Flap surgery is a reconstructive surgical technique where tissue (skin, muscle, fat, or bone) is moved from one part of the body to another to repair defects caused by trauma, cancer removal, burns, or chronic wounds. Unlike skin grafts, flaps carry their own blood supply, ensuring better healing, function, and durability.

What is flap surgery?

Flap surgery involves transferring tissue from a healthy part of the body (donor site) to an area that needs reconstruction (recipient site). The flap may include skin, fat, muscle, or even bone, depending on the type of defect.

When is flap surgery needed?

It is usually recommended for:

• Cancer reconstruction (head & neck, breast, limb)
• Trauma repair (accidents, crush injuries, amputations)
• Burns and chronic wounds (pressure sores, diabetic ulcers)
• Congenital defects (such as cleft lip/palate reconstruction)
• Orthopedic reconstruction after bone loss or fractures

What are the types of flap surgery?

• Local flap: Tissue moved from an area close to the wound
• Regional flap: Tissue transferred from a nearby region
• Free flap (microvascular flap): Tissue completely detached and reattached using microsurgery to connect blood vessels
• Muscle, skin, or bone flaps: Depending on tissue needed

Is flap surgery safe?

Yes. Flap surgery has high success rates, especially in specialized centers. Risks include infection, flap failure (rare), or delayed healing, but outcomes are excellent when performed by experienced reconstructive surgeons.

How is flap surgery different from skin grafting?

• Skin grafts only transfer the top skin layer and rely on the new site for blood supply.
• Flaps carry their own blood supply, making them stronger, more durable, and suitable for deeper or complex defects.

What is recovery like after flap surgery?

• Hospital stay: 5–10 days, depending on the surgery type
• The flap is closely monitored for proper blood flow
• Light activities: 2–3 weeks
• Full recovery: 6–12 weeks

Physiotherapy may be needed if muscles or limbs are involved

What are the benefits of flap surgery?

• Provides durable coverage for complex wounds
• Restores both appearance and function
• Helps save limbs or body parts that might otherwise need amputation
• Improves quality of life after cancer or trauma surgery
