Wound opening after arm or thigh lift: why it happens, how it is prevented and how it is treated

By Dr Sanjay Parashar, plastic surgeon · Dubai London Hospital, Jumeirah · 23 October 2026

An arm lift (brachioplasty) or thigh lift (thighplasty) removes loose skin, often after major weight loss. The scars are long and sit in areas that move, rub and stay warm and moist. Most heal well. When part of the wound opens, there is usually a reason, and many of those reasons can be planned for before surgery. Here I explain the SafePlast fundamentals I apply in my own practice, and how an open arm or thigh lift wound is treated.

First: is this urgent?

Contact your surgeon the same day, or go to an emergency department, if you have any of these:

• Fever, shivering or feeling generally unwell
• Redness or swelling that is spreading
• Pain that is getting worse rather than better
• Grey, dark or blistering skin around the scar
• Sudden swelling or a tense, bruised area on one side
• Foul-smelling or increasing discharge

Severe pain, a fast heart rate or feeling very unwell in the first days after surgery can be signs of a serious infection. Do not wait for a routine appointment.

What wound opening looks like

Wound opening (dehiscence) can be a small gap of a few millimetres or a longer separation along the scar. In thigh lifts it is most often seen in the groin crease or where two scars meet (the T-junction). In arm lifts it usually appears near the armpit or along the inner arm. It often starts around day 6 or 7, when early swelling and movement put the most strain on the healing edges.

Six SafePlast fundamentals I apply to every arm and thigh lift

1. Choosing the right time

A thigh lift works best once weight loss is complete and stable. In my experience, a thin, deflated thigh gives a better and safer result than a large, fatty thigh. Heavy thighs put more weight and tension on the wound, and the result is less predictable. The same applies to the arm lift. If more weight loss is planned, I usually advise waiting.

2. Not removing too much skin

Removing too much skin, or lifting (undermining) the skin too widely, is the main cause of wound gaping. It also causes problems later: a tight, pulled look and a limb that is out of proportion. I plan the amount of skin to remove carefully and keep undermining to what the lift needs, so the wound closes without strain.

3. Avoiding or protecting the T-junction

The point where two scars meet, the T-junction, is always the weakest spot. Where I can, I avoid it, either with a vertical (longitudinal) lift alone or with an L-shaped technique. When a T-junction is needed, I modify the incision to reduce tension at that point and do not place suture knots in the junction itself.

4. SIS and SIT to control bleeding

I use a standard infiltration solution (SIS) placed with a stratified infiltration technique (SIT), layer by layer, before and during surgery. This limits bleeding, which helps prevent a haematoma (a collection of blood under the skin). A haematoma presses on the wound from inside and is a common start to wound breakdown.

5. Qualified surgeons in an accredited facility

Infection is one of the most serious causes of wound breakdown after body lifts. Surgery by a qualified plastic surgeon, in an accredited hospital with proper sterile standards and monitoring, reduces that risk and improves safety overall. Many of the open wounds we treat follow surgery done elsewhere, sometimes abroad, without these safeguards.

6. Rest after surgery

Rest matters, especially after a thigh lift. I recommend two weeks of rest at home, walking only for essentials. Wound gaping usually shows around day 6 or 7, so the first two weeks are when protecting the wound counts most. Sitting with legs wide apart, stretching, climbing and returning to the gym early all pull on the scars.

Your own risk factors

Smoking or vaping, diabetes, a high BMI, poor nutrition after weight-loss surgery and some medicines all slow healing. Tell your surgeon about each of these before surgery, so they can be addressed in advance.

If your arm or thigh lift wound has already opened

An open wound after a lift does not always mean months of dressings or a skin graft. My aim is to close it as soon as it is safely possible, in four steps.

1. Assess and treat the cause. We check for infection, a collection of blood or fluid, and dead tissue, and treat any infection first.
2. VAC therapy. Negative-pressure (VAC) dressings clean the wound, reduce swelling and draw the edges together.¹
3. Minimal debridement. We remove only tissue that is clearly dead, keeping as much healthy skin as possible for closure.
4. Close it early using skin creep. Healthy skin stretches slowly under steady tension.^2,3,4 By mobilising the surrounding skin with anchoring sutures and VAC, we advance it over the wound instead of taking a skin graft from somewhere else. “In reconstructive surgery we often rob Peter to pay Paul. Here we enrich Paul to pay for himself.”

Once the wound has closed, scar management begins: silicone, massage, sun protection and, where needed, further scar treatment.

Case example: a young patient developed necrotising fasciitis after arm and thigh lifts abroad. Her large open wounds were closed without skin grafts, with 2 days in hospital. Read the full case.

Frequently asked questions

When does a thigh lift wound usually open?

Most often around day 6 or 7, when swelling and movement put the most strain on the healing edges. This is why I advise two weeks of rest at home after a thigh lift.

Why is the groin or T-junction the usual weak spot?

It is where tension, movement and moisture meet, and where two scars join. I avoid a T-junction when I can and protect it when I cannot.

Will I need a skin graft?

Often not. Many open wounds can be closed with VAC therapy and anchoring sutures that stretch the surrounding skin, which avoids a new wound at a donor site. The right treatment is decided only after an examination.

Should I wait until I lose more weight before an arm or thigh lift?

Usually yes. A lift works best when weight is stable and the limb is deflated rather than full.

I had my lift abroad. Can you still help?

Yes. Bring your operation notes and medication list, or send photos on WhatsApp so we can advise on the next step.

What you can do now

• Do not ignore a wound that is opening, leaking or changing colour
• Keep it clean and covered, and avoid creams your surgeon has not advised
• Send us photos on WhatsApp or book an assessment at Dubai London Hospital
• If you had surgery abroad, bring your operation notes and medication list
