What is complex wound closure?
Complex wound closure is the reconstructive surgery that repairs defects of skin and soft tissue that cannot be closed with a simple suture. It is used when tissue is missing, when the edges cannot meet without excessive tension, when deep structures —bone, tendon, cartilage, an implant— are left exposed, or when a wound has failed to heal on its own within a reasonable time.
A wound is considered complex because of its size, its location or the ground on which it appears. This category includes chronic ulcers (pressure, venous or diabetic-foot), dehiscence of a previous surgery that has reopened, defects after trauma or after removal of a skin tumour, wounds on previously irradiated tissue, and wounds that have become infected or chronic. In all these cases stitching the edges is not enough: healthy, well-vascularised tissue must be brought in.
The goal is not to cover the wound any way possible, but to achieve coverage that holds, heals and does not reopen. That is why an important part of the work happens before closing: preparing the bed, controlling infection and choosing the right tissue for each defect.
Techniques used by Dr. Arístides Arellano
Reconstruction follows an ordered principle —the reconstructive ladder— moving from the simplest option to the most complex, choosing the simplest one capable of solving the problem durably. No rung is climbed without need, and no simple closure is forced where tissue is actually missing:
- Debridement. Almost always the first step. Devitalised, infected or fibrotic tissue is removed until a clean, bleeding bed remains, one able to accept a graft or support a flap. Without good debridement, any closure fails.
- Delayed primary closure and edge advancement. When, after preparing the wound, the tissues allow approximation without tension, it is closed directly or with small advancements. It is the simplest option and the preferred one when viable.
- Skin grafts (split- or full-thickness). A sheet of skin taken from another body area covers a clean, well-vascularised bed with no deep structures exposed. It resolves broad surfaces, at the cost of a donor site.
- Local flaps. Tissue next to the wound is mobilised while keeping its own blood supply to cover the defect. Because it carries its own circulation, a flap can cover exposed bone, tendon or hardware, where a graft would not take.
- Regional or pedicled flaps. When neighbouring tissue is not enough, tissue from a nearby region is transferred on its vascular pedicle. These are reserved for larger defects or for areas that are hard to cover.
- Negative-pressure therapy as an adjunct. A vacuum wound-care system that reduces oedema, controls exudate and stimulates granulation tissue. It does not close the wound by itself: it prepares the bed for the definitive graft or flap.
- Tissue expansion in staged reconstructions, when additional healthy skin must be grown before definitive closure.
How is it performed?
The procedure is planned according to the size, location and condition of the wound, and so there is no single type of operation. A small, clean defect may be resolved under local anaesthesia in one stage; an extensive reconstruction, over infected or irradiated tissue, may require regional or general anaesthesia, an initial debridement and a definitive closure in a second operation days later, once the bed is ready.
The usual sequence is: assess and debride, control infection and bleeding, decide in the operating room itself —based on what is found— which rung of the reconstructive ladder applies, and cover the defect with the chosen tissue. When there is a donor site (graft or flap), its closure is also addressed. Staged reconstruction is the rule, not the exception, in the most difficult wounds: trying to close too soon is one of the most frequent reasons a wound reopens.
All surgery carries risk and requires a prior medical assessment. Results may vary according to each patient, their anatomy and their individual healing process.
Who is a good candidate?
- People with a wound that will not close by conventional means: chronic ulcers, dehiscence, defects after trauma or after removal of a skin tumour.
- Defects with deep structures exposed (bone, tendon, cartilage, an implant) that need vascularised coverage.
- Patients whose general state and local conditions allow healing: it is essential to control the underlying disease first —diabetes, venous insufficiency, smoking— because much of the result depends on it.
- Willingness to accept an additional donor site when the case requires a graft or flap, and to follow wound care to the letter.
- Realistic expectations. The goal is stable, functional coverage; the resulting scar is made as discreet as possible, but a reconstruction leaves a mark and does not return the skin to its previous state.
Recommended post-surgical treatments
Healing of a complex wound depends as much on technique as on aftercare and on the blood supply of the reconstructed tissue. Depending on the case, Dr. Arístides may recommend hyperbaric-chamber oxygenation to support the viability of grafts and flaps, and lymphatic drainage to control oedema. See the full guide: Post-surgical recovery and care.
Before and after
Most patients want to see before-and-after photographs before deciding. Out of respect for each person’s privacy, Dr. Arístides Arellano shows real cases —always with documented consent— during your in-person consultation, where you can review results from patients with a starting point similar to yours. Results may vary from patient to patient.
Approximate price
Complex wound closure has no catalogue price, and publishing one would be misleading: no two wounds are alike. The cost depends on the size and location of the defect, on the reconstructive technique required (graft, local or regional flap), on whether several operations are needed, on the type of anaesthesia and on hospital fees. It is defined at the consultation, after examining the wound, with clear written information. Approximate price — the definitive cost is set at your private consultation with Dr. Arístides Arellano.

About Dr. Arístides Arellano
Dr. Arístides Arellano is a plastic surgeon holding a specialty licence: he practises under a Mexican medical licence (D.G.P. 1125959) and a specialty licence in Plastic & Reconstructive Surgery (0002008), both issued by the Directorate General of Professions (DGP), which reissued his certificate of professional standing in 2025. His career began before Mexico’s present-day specialty-board system existed: he belongs to the founding generation of plastic surgery in Puebla, the second generation of a surgical tradition started in 1971 by Dr. Francisco Arellano Ocampo. Trust is verified, not promised: both licences are public and anyone can look them up in the DGP’s National Registry of Professionals.

Recovery · step by step
- Days 0–3Rest, elevation of the area and dressings. The colour and viability of the reconstructed tissue and of the donor site are monitored.
- Days 4–10Regular dressings. For grafts this is the critical take-in period; any friction or pressure on the area is avoided.
- Weeks 2–4Sutures removed depending on the area. The wound gains strength; activity is reintroduced gradually and under control.
- Months 1–3Scar maturation. Sun protection is maintained and, if indicated, massage or measures to improve the final appearance.
- Months 3–12The scar flattens and lightens gradually. The definitive result takes months to settle.
Frequently asked questions
What is a complex wound?
It is a wound that cannot be closed with a simple suture. It may be so because of its size, because skin is missing, because the edges will not meet without tension, because it leaves bone or tendon exposed, or because it has not healed on its own. This includes chronic ulcers, dehiscence of a previous surgery, and defects after trauma or after removal of a skin tumour.
What does complex wound closure involve?
It involves reconstructive surgery that brings in healthy, well-vascularised tissue to cover the defect durably. It follows the reconstructive ladder: first the wound is debrided and the bed prepared, then it is closed with the simplest option that works, whether edge advancement, skin graft or flap. The goal is coverage that does not reopen.
How many surgeries do I need?
It depends on the wound. A small, clean defect may be resolved in a single stage; a large, infected or irradiated wound usually needs an initial debridement and a definitive closure days later, once the bed is ready. Staged reconstruction is the rule in the most difficult cases, because closing too soon makes the wound more likely to reopen.
What is the difference between a graft and a flap?
A graft is a sheet of skin with no blood supply of its own, placed on a clean, well-vascularised bed from which it draws its circulation; it does not work where bone or tendon is exposed. A flap carries its own blood supply, so it can cover exposed deep structures or areas of poor circulation. The choice depends on the defect.
Will I be left with a scar?
Yes. Every reconstruction leaves a scar, both on the repaired area and on the donor site when a graft or flap is used. The goal is stable, functional coverage and making the scar as discreet as possible; it is not to return the skin to its previous state. Aftercare and sun protection strongly influence the final appearance.
Why is it important to control diabetes or smoking first?
Because healing depends on blood supply and general condition. Poorly controlled diabetes, venous insufficiency and smoking reduce blood flow to the tissue and greatly raise the risk that a graft or flap will not take. Controlling the underlying disease before surgery is part of the treatment, not a formality.
How much does complex wound closure cost in Puebla?
It has no catalogue price because no two wounds are alike. The cost depends on the size and location of the defect, on the technique required, on whether several operations are needed, on anaesthesia and on hospital fees. It is defined at the consultation, after examining the wound and with clear written information. Results may vary.
