Wound Separation After Plastic Surgery: Small Opening vs Emergency

What wound separation is

Wound separation, or dehiscence, means that part of a closed incision has come apart. It most often shows up at points of greatest tension, such as where two incision lines meet or where skin was pulled tight to close the wound. Some openings involve only the outer skin; others go deeper into the fat or, rarely, further.

It is a known risk rather than a freak event. The American Society of Plastic Surgeons lists poor wound healing, skin loss and fat necrosis (death of fatty tissue under the skin) among the risks of a tummy tuck, alongside infection and fluid accumulation, all of which can be involved when an incision opens.

Small opening or urgent problem: a triage table

Use this as a way to describe what you see to your surgeon, not as a way to diagnose yourself. Every column calls for contact; the right-hand column calls for in-person assessment without delay.

Go to an emergency department rather than waiting for a reply if there is heavy bleeding, if you feel faint or confused, or if you have trouble breathing.

Why incisions open

Usually several factors combine. Common ones include:

• Tension on the closure, especially when bending, lifting or straining too early.
• Blood supply to the skin edges, which can be reduced by the operation itself or by nicotine; see our article on nicotine testing before surgery.
• Fluid under the skin, such as a seroma, pushing on the wound from below.
• Infection weakening the healing tissue.
• Friction from a garment edge, foam pad or waistband rubbing the incision.
• General health, including diabetes control and nutrition.

You cannot control all of these, which is why an opening is not automatically anyone's fault. What you can control is how fast it is reported.

The first hour: what to do

1. Wash your hands before touching anything near the wound.
2. Do not press, probe or try to close the opening.
3. If your team has given you dressings, cover the area with a clean, dry dressing as they showed you.
4. Take photographs (see below).
5. Contact your surgeon, send the photos and describe what you see using the table above.
6. Write down when you first noticed it, and check again at the interval your surgeon gives you.

Photos that help remote triage

• Good natural light, with no filter or flash glare.
• One wide shot showing where the opening is on your body, and one close-up.
• Something for scale beside the wound, such as a ruler or coin.
• The same angle each time, so changes are easy to compare.
• Any dressing that came off, showing the amount and colour of drainage.

Photos help, but they have limits. A picture cannot show depth reliably, cannot be probed, and cannot be cultured. If your surgeon asks to see you, go.

What not to do

• Do not use superglue, household tape pulled tight, or butterfly strips you bought yourself to close the gap.
• Do not apply herbal remedies, powders, honey or creams that were not prescribed.
• Do not soak the wound in a bath, pool or the sea.
• Do not tighten your garment over the area to hold it together.
• Do not start silicone or scar products on an open wound; they are for healed skin. Our guide to scar care after plastic surgery explains when they start.
• Do not wait for your next scheduled appointment if the wound is changing.

Lowering the odds, before and after surgery

No plan removes the risk entirely, but some steps are in your hands:

Before surgery

• Tell the surgeon about any history of slow healing, wound problems after previous operations, diabetes or recent weight loss.
• Stop nicotine in all forms for as long as your surgeon asks, and be honest if you have not.
• Ask which parts of your incision will carry the most tension, so you know where to look.

During recovery

• Follow the position and activity limits you are given, even when you feel well.
• Check the incision once or twice a day at dressing changes, using the same light.
• Keep garment edges and foams off the incision line.
• Report swelling or a fluid sensation early, before pressure from below has a chance to stress the wound.
• Keep the dressings and supplies your team gave you, rather than improvising with household items.

How surgeons commonly manage it

Treatment depends entirely on what the surgeon finds. Options can include local wound care with dressings while the area heals from the bottom up, removing tissue that is not healing, taking a sample if infection is suspected, draining a fluid collection underneath, or, in some cases, closing the wound again. Healing from an opening can take time and may leave a wider scar, which can sometimes be addressed later once everything has matured. Signs of infection, such as fever and spreading redness, change the picture; see our article on post-op fever.

If it happens after you fly home

Openings can appear after you have left Medellín, when your surgeon is a video call away. The CDC Yellow Book (2025) advises medical travelers to discuss a plan for complications with both their home clinician and the clinician abroad, to arrange local follow-up before travel, and to be aware that some overseas providers charge substantial fees for follow-up care. Practically, that means:

• Before the trip, identify a local doctor, urgent care or wound clinic willing to see you after surgery abroad.
• Bring your operative report and discharge instructions in English, so a local clinician knows what was done.
• Ask your Medellín surgeon how they will co-manage with a local doctor, and whether any follow-up is included in your fee.
• Budget for local care, since a wound that needs regular dressing changes can take weeks.
