What do patients ask about dog-ears after a tummy tuck?

Q: What are the key takeaways about dog-ears after a tummy tuck?

A dog-ear is a geometry problem : a straight excision on a curved body leaves unequal skin edges. A straight incision also concentrates tension at its two ends, which widens the scar there over time. Prevention starts with a standing assessment and a curved excision that sweeps up at the ends. A layered closure carries the load in the deep layers, so the skin and the ends of the scar sit without tension; a drain is always placed. A boxy flank is a separate planning failure , answered by the lateral extension or, where fat is the cause, by liposuction. Preventing a dog-ear is far simpler than revising one once it has healed.

Question 2

What is a dog-ear, and why does it form?

Accepted Answer

A dog-ear is a cone-shaped bunching of skin and the fat beneath it at the lateral end of a surgical incision, and it forms because a straight excision taken from a curved surface leaves the two edges of the wound at unequal lengths. Understanding that precisely is the whole of the solution, because once the cause is geometric, the prevention is geometric too.

Question 3

Why does a straight incision leave unequal edges?

Accepted Answer

A straight incision leaves unequal edges because the abdomen is not flat: when an ellipse of tissue is removed along a straight line and the wound is closed, the upper edge at each end is longer than the lower one, and the surplus has nowhere to go except upward into a fold. The longer and flatter the incision, the greater the discrepancy and the more pronounced the dog-ear.

Question 4

Why does tension gather at the ends of the scar?

Accepted Answer

Tension gathers at the ends of a straight scar because the forces of closure converge on its two poles, which places them under the highest tension anywhere in the wound. High tension there widens and thickens the scar, and it is also what turns a minor dog-ear at the end of the operation into a more pronounced one at six months, because tension stretches tissue. A dog-ear is therefore both a surplus problem and a tension problem, and a plan has to solve both.

Question 5

How is the excision designed so that no dog-ear forms?

Accepted Answer

The excision is designed so that no dog-ear forms by marking it standing and drawing it as a curve that sweeps gently upward at its lateral ends, extending slightly higher and further toward the hips than a straight mark, so that the surplus that would otherwise bunch at the ends is taken inside the excision and the two edges meet at equal length when the midline is closed. Dog-ear prevention therefore begins in the consultation room, with the patient standing in the body's natural position: I read the distribution of skin laxity not only across the central abdomen but across the flanks, hips and lower back, to understand how the tissue will behave when the midline is tightened, and I follow the curves of the hip and waist with the line rather than crossing them. What I observe standing I plan standing, because the result the patient will live in is a standing result, and the marked curve is then followed precisely in the operating room; any shortcut back toward a straight line reintroduces the problem the design removed. Changing the line and angle of the incision in this way has been tested directly: a 2017 open-label randomized trial in 70 abdominoplasty patients compared the classic high-lateral-tension technique with a method built on exactly such a modification and found the resulting scar significantly shorter, a mean of 41.7 cm against 53.7 cm. Its authors describe the method as newly introduced and call for longer follow-up, so it establishes a measured advantage in scar length rather than a settled standard.

Question 6

How does the closure keep the ends of the scar free of tension?

Accepted Answer

The closure keeps the ends of the scar free of tension because the design has already removed the surplus that would have gathered there, and because the closure is layered: the deep layers of the wound are brought together first and carry the load, so that the skin edge, and the two ends in particular, only has to meet. I do not use progressive tension sutures between the flap and the fascia; the tension at the poles is prevented by the shape of the excision rather than managed afterward by extra suturing. A drain is always placed beneath the flap to prevent fluid collecting while the tissues heal together. The full layered closure, from the muscle repair up to the skin, and how it is adjusted to the quality of the patient's tissue, is the subject of my article on tissue elasticity, incision length and closure strategy.

Question 7

Why does a tight front sometimes meet a boxy flank?

Accepted Answer

A tight front sometimes meets a boxy flank because the abdomen was treated as a flat panel rather than as one face of a three-dimensional torso: the midline was tightened and the sides, which carry their own fat and their own skin laxity, were left as they were, so the operation reads as local rather than whole and is visible from every angle except the front. The transition is planned at the same standing assessment as the excision, and the answer depends on what is causing the step. Where it is skin, the lateral extension of the curved excision takes it in. Where it is fat, liposuction of the flanks is added to the plan, with conservative suction that restores the natural curve from front to side to back; it is added when the assessment calls for it, not as a routine part of every tummy tuck. Why the front alone leaves a boxy torso, and what the blood supply allows in one operation, is the subject of my article on combined tummy tuck and liposuction; how the skin itself is redraped to shape the waist is in my article on strategic skin redraping.

Question 8

How does a straight excision compare with a designed one?

Accepted Answer

A straight excision and a designed one differ at every step from the marking to the flank, and the table sets them side by side.

Question 9

What happens if a dog-ear still appears?

Accepted Answer

If a small dog-ear still appears, it is revised with a short lateral excision under local anesthesia once the swelling has resolved and the scar has settled, at about three to six months; because the incision line is designed in advance so that it will not produce one, this is uncommon. Fullness at the ends of the wound in the first weeks is usually swelling and settles with it; what remains, in the rare case, is a minor procedure. That is categorically different from the major correction a significant dog-ear from a poorly planned primary operation requires, which means dissecting through scar, addressing tension in a field that has already healed and accepting compromised elasticity and blood supply. The contrast is the argument of this article: engineering the result correctly at the outset is always the better strategy.

Question 10

Which questions tell you whether a surgeon prevents dog-ears?

Accepted Answer

Four questions tell you whether a surgeon prevents dog-ears: how the lateral ends of the excision are designed, how the closing force is distributed, how the transition to the flank is planned, and what happens if a dog-ear appears anyway. A surgeon who discusses only the central incision, the belly button and the muscle repair is describing an operation that addresses the front and leaves the sides to chance; one who can answer these questions specifically has met the problem technically rather than only aesthetically. That is the standard I hold for every tummy tuck I perform, and it runs through all of my plastic surgery practice in Dubai.

Question 12

What exactly is a dog-ear after a tummy tuck?

Accepted Answer

A cone of bunched skin and fat at one or both ends of the scar. It forms when a straight excision leaves the two edges of the wound at unequal lengths, so the surplus has nowhere to go but upward into a fold. It is not a healing complication; it is the consequence of how the excision was drawn, which is why it is prevented by drawing the excision as a curve that takes the surplus inside it.

Question 13

Can a dog-ear go away on its own?

Accepted Answer

Swelling at the ends of the wound in the first weeks can look like a dog-ear and usually settles within about three months. A true dog-ear, where there is real surplus skin, does not resolve on its own; it is corrected with a short lateral excision under local anesthesia at about three to six months, once the swelling has gone and the scar has settled. Prevention by design is always preferable to that correction.

Question 14

Why does a straight tummy tuck incision cause dog-ears?

Accepted Answer

Because the body is curved and the line is not. When an ellipse is removed along a straight line from a curved surface, the upper edge at each end is longer than the lower one, and sewing them together bunches the difference into a cone. A curved excision that follows the body produces edges of equal length and removes the problem at its source.

Question 15

Does a curved incision mean a longer scar?

Accepted Answer

Sometimes slightly, and it is a good trade. A scar that lies under no tension heals finer and fades better than a shorter one that is pulled at its ends, and in the one randomized trial that measured it, a modified lateral design produced a shorter scar than the classic technique. The correct length is set by your skin's elasticity rather than by a target number, and the curve is placed so that the whole scar sits low, beneath the bikini line.

Question 16

Is flank liposuction part of every tummy tuck?

Accepted Answer

No. It is added when the standing assessment shows that fat at the flanks would leave a step between the tightened front and the sides; where the step is skin rather than fat, the lateral extension of the excision deals with it without liposuction. The transition is always planned; the method depends on what is causing it.

Question 17

How do I know if my surgeon's approach will prevent dog-ears?

Accepted Answer

Ask how the lateral ends of the excision are designed, how the closing force is kept off the skin, how the transition to the flank is planned, and what is done if a dog-ear appears anyway. A surgeon who answers in specifics, a curved design marked standing, a layered closure, a planned flank, has met the problem technically. A generic answer, or no mention of the ends of the scar at all, suggests a plan that treats the front and leaves the sides to chance.

Step	Straight-line excision	Designed excision
Marking	A midline mark, often lying down	A standing assessment of the whole torso
Shape of the excision	Straight	Curved, sweeping upward at the ends
The lateral ends	Left to chance; surplus bunches	Surplus taken inside the excision; edges meet at equal length
Where the closing force is carried	By the skin edge, most of all at the poles	By the deep layers of a layered closure, with the surplus already removed by the design
Space beneath the flap	Drain	Drain, always
Transition to the flank	Not planned	Planned: by the lateral extension, or by liposuction where fat is the cause
Dog-ear	A recognized risk	Designed out before the first incision
