Dog ears after breast reduction are small, puckered mounds of excess skin and tissue that form where incision lines meet or end, and they can usually be corrected through a relatively straightforward surgical revision, liposuction, or a combination of both. They are one of the more common contour complaints following breast surgery, but they are also among the most fixable. The fix depends on the size and location of the dog ear, how long ago your initial surgery was, and what technique your surgeon used the first time around.
What Dog Ears Actually Are
A dog ear is a small ridge or fold of skin that bunches up at one or both ends of a surgical incision. The name comes from the way the puckered tissue can resemble the floppy tip of a dog’s ear. After breast reduction, dog ears most often show up along the inframammary fold (the crease under the breast), at the outer edges of the horizontal scar in an anchor-pattern incision, or at the bottom end of the vertical scar in a lollipop-pattern incision. They can also appear along the lateral chest wall, closer to the armpit.
The underlying cause is a mismatch in length between the two sides of skin being brought together. When a surgeon closes an incision and one edge of the wound is longer than the other, the excess skin has nowhere to go except upward, creating a raised bump. This is a basic geometric problem in any surgery that removes tissue and then closes skin over a curved surface, and breasts, being three-dimensional and soft, make it especially likely. The inverted-T (anchor) technique commonly forms dog ears at the ends of the horizontal incision precisely because of this length discrepancy between the adjacent wound margins.1PubMed Central.

Will Dog Ears Go Away on Their Own?
This is the first thing most people want to know, and the honest answer is: sometimes, partially. In the weeks and months after surgery, swelling gradually resolves and tissues settle into their new shape. A small bump that looked alarming at six weeks can flatten out by six months as the skin redrapes. Your surgeon will likely tell you to wait at least six to twelve months before judging the final contour, because premature concern can lead to unnecessary revision.
That said, a true dog ear caused by excess tissue rather than by swelling is structural. No amount of healing will make extra skin disappear on its own. If you can pinch the bump and feel a definite fold of redundant skin or fatty tissue, and it persists beyond a year, it is unlikely to improve further without intervention. Compression garments, scar massage, and time can soften the area, but they cannot eliminate a geometric surplus of tissue.
Surgical Excision for Dog Ear Correction
The most common and reliable way to get rid of a dog ear is a minor surgical revision. In many cases, this can be done under local anesthesia in a procedure room rather than requiring a full trip to the operating room. The surgeon removes the puckered tissue and re-closes the incision so that both edges are the same length. The trade-off is a slightly longer scar, since correcting the mismatch typically means extending the incision line a small amount.
One well-studied approach is the 90-degree incision technique, which involves making a precise cut perpendicular to the original scar line to remove the dog ear. A study that applied this method in 32 patients found complete resolution of the deformity with scars placed along the skin’s natural tension lines, and no cases of skin breakdown, wound separation, or raised scarring over a year of follow-up.3PubMed Central. Aesthetic refinement of the dog ear correction: the 90° incision technique and review of the literature The appeal of this approach is that the resulting scar tends to hide well because it follows the lines where skin naturally creases.
Recovery from a dog ear excision is typically much shorter than from the original breast reduction. You are dealing with a smaller wound, less tissue disruption, and far less swelling. Most people can return to normal activities within a week or two, though your surgeon will advise you to avoid heavy lifting for several weeks while the new scar matures.
Liposuction as a Less Invasive Option
When the dog ear is composed more of fatty tissue than of redundant skin, liposuction can be a good alternative to cutting. A small cannula is inserted through a tiny incision and used to suction out the excess fat, smoothing the contour without adding a longer scar. This approach works best for soft, fatty dog ears rather than firm, skin-heavy ones.
Research supports this approach for breast contouring. A study comparing liposuction to direct tissue removal in vertical breast reductions found that liposuction accomplished effective contouring of the lower pole of the breast and reduced revision rates with a low complication rate, and was particularly helpful in large breasts with an ill-defined lateral border.4PubMed. Contouring the inferior pole of the breast in vertical mammaplasty: suction-assisted lipectomy versus direct defatting The same principle applies to post-surgical dog ears: in the right patient, liposuction can smooth the area without a scalpel. Studies on dog-ear deformities after breast reconstruction have likewise described liposuction as a simple method that avoids additional incisions.5Chinese Journal of Plastic Surgery. Refinement of dog-ear deformity following autologous flap breast reconstruction by liposuction
Liposuction for dog ears is usually a quick procedure done under local anesthesia with or without light sedation. Bruising and swelling are common for a couple of weeks. The final result takes a few months to settle as the skin contracts over the newly reduced area. The main limitation is that if the problem is primarily loose skin rather than excess fat, liposuction alone will not fully correct the issue and you may still need a small excision.
When to Seek Revision and What to Expect
Timing matters. Most plastic surgeons recommend waiting at least six months, and ideally a full year, after the original breast reduction before pursuing dog ear correction. There are two reasons for this. First, swelling and tissue remodeling are still ongoing for many months, and what looks like a dog ear at three months may settle into an acceptable contour by nine months. Second, scar tissue needs to mature before a revision can be performed safely and with the best cosmetic result. Operating on immature scars increases the risk of poor healing.
When you do consult your surgeon, expect them to assess the dog ear by looking at it, pinching it, and possibly asking you to stand in different positions. They will determine whether the bulk is mainly skin, fat, or both, which dictates the approach. In some cases, a combination of excision and liposuction gives the best result: the surgeon excises the redundant skin flap and then uses liposuction to feather the surrounding area smooth.
One practical detail worth knowing: dog ear revision after breast reduction is often covered by insurance if the original breast reduction was medically indicated and the dog ear is causing functional issues like irritation, chafing, or hygiene problems. If the correction is purely cosmetic, coverage varies. Ask your surgeon’s office to check with your insurer before scheduling.
Why Some People Get Dog Ears and Others Do Not
Dog ears are not a sign that your surgeon did something wrong. Some breast shapes and body types are more prone to them. Patients with a wide breast base, significant skin laxity, or a large difference in breast volume before surgery are at higher risk because the geometric mismatch during closure is harder to manage. The choice of surgical technique also plays a role. The vertical (lollipop) pattern has become increasingly popular because it produces a shorter scar, but it is more prone to dog-ear formation along the lower part of the incision compared to the anchor pattern.2PubMed Central. The 5 D’s to Dunk the Dog: A Retrospective Clinical Review to Prevent Dog-Ear Contour Abnormalities in Vertical Breast Reductions and Breast Lifts The anchor pattern, conversely, tends to produce dog ears at the lateral and medial ends of the horizontal incision.1PubMed Central. Dog-ear’s prevention during Inverted-T breast lift and reduction
Weight changes after surgery can also contribute. If you gain or lose a significant amount of weight after a breast reduction, the skin and fat redistribution can unmask or worsen a dog ear that was borderline at the time of surgery. This is another reason surgeons prefer to operate when a patient’s weight is relatively stable.
How Surgeons Prevent Dog Ears During the Initial Procedure
If you have not yet had your breast reduction, or are in the planning stages, it is worth understanding what your surgeon can do upfront to minimize the chance of dog ears forming at all. Prevention is easier than correction, and the surgical literature describes several reliable techniques.
For inverted-T (anchor) reductions, one approach involves curving the upper incision lines downward so they meet the inframammary fold line at a 90-degree angle at both corners. This distributes the excess skin length toward the center of the closure rather than bunching it at the ends. The technique creates a small “L” shape at each corner of the incision pattern, and combined with careful suturing that matches the distance from the corner equally on both flaps, it has been shown to prevent dog ear formation entirely.1PubMed Central. Dog-ear’s prevention during Inverted-T breast lift and reduction
For vertical reductions, a systematic five-step intraoperative technique was shown to nearly eliminate dog ears in a clinical review of 58 patients across 89 breasts over 13 years. Only one patient developed a dog ear, a rate under 2%, and that patient did not request revision, giving the technique a 0% revision rate over the entire study period.2PubMed Central. The 5 D’s to Dunk the Dog: A Retrospective Clinical Review to Prevent Dog-Ear Contour Abnormalities in Vertical Breast Reductions and Breast Lifts These numbers suggest that when surgeons are deliberate about addressing the geometry of the closure during the initial operation, dog ears are largely avoidable.
This does not mean you should blame your surgeon if you end up with one. Not every breast anatomy cooperates equally, and some degree of skin redundancy is an accepted trade-off to avoid making the scar excessively long during the first surgery. Many surgeons intentionally leave a small amount of excess rather than extend the incision further, knowing that a minor revision later is simpler than a long scar that tracks too far toward the back or sternum. If your surgeon mentioned this possibility before your procedure, that was good communication, not a warning sign.
Dog Ears Versus Other Contour Irregularities
Not every bump along a breast reduction scar is a dog ear. In the early months after surgery, you may notice puckering, scar thickening, or asymmetric swelling that mimics the appearance of a dog ear but has a different cause. Hypertrophic scarring, for example, produces a raised ridge along the incision line that can look like a fold of excess skin but is actually overgrown scar tissue. The treatment for hypertrophic scarring is different: silicone sheets, steroid injections, or laser therapy rather than excision.
Seroma, a collection of fluid under the skin, can also create a bump in the early postoperative period that resembles a dog ear. Seromas usually resolve on their own or with a single drainage in the office. If your bump appeared within the first few weeks after surgery and feels soft or fluid-filled, mention it to your surgeon promptly rather than assuming it is a permanent contour issue.
The distinguishing feature of a true dog ear is that it is a fold of skin or skin-plus-fat sitting at the end or junction of your incision, it persists unchanged beyond six months, and you can physically pinch it between your fingers as a discrete flap. If what you are feeling runs along the length of the scar rather than sitting at a corner, or if it appeared suddenly weeks after surgery, it is worth having your surgeon evaluate it to rule out other causes.
Choosing a Surgeon for Dog Ear Revision
You do not have to return to the surgeon who performed your original breast reduction, although many people do. If you are considering seeing someone new, look for a board-certified plastic surgeon with specific experience in breast revision surgery. Dog ear correction is a minor procedure in the spectrum of plastic surgery, but the nuances of scar placement, tissue handling, and matching the correction to your existing scars require someone who does this regularly.
During your consultation, ask how many dog ear revisions the surgeon has performed, whether they anticipate using excision, liposuction, or both, and what the expected scar impact will be. A good surgeon will be honest about the trade-off between removing the dog ear and potentially lengthening the scar. In most cases, the additional scar length is small and well worth the improved contour, but you should understand the plan before agreeing to it.
If your original surgeon is available and you had a good experience, there is an advantage to returning to them. They already know your anatomy, your tissue quality, and the exact technique they used, which helps them plan the revision efficiently. They may also offer the revision at a reduced fee or as part of a revision policy included in your original surgical fee, since many plastic surgeons build one complimentary revision into their pricing for breast reduction patients.
