Umbilicoplasty is surgery to reshape, reposition, or reconstruct the belly button. It ranges from a minor cosmetic tweak on a navel someone has always disliked to a full reconstruction after major abdominal surgery has left no belly button at all. The procedure is most commonly performed as part of a tummy tuck, where the navel must be relocated through a new opening in the repositioned skin, but it also exists as a standalone operation for people who simply want a different-looking navel.
What Research Says About the “Ideal” Navel
Before understanding what umbilicoplasty tries to achieve, it helps to know what surgeons are aiming for. Multiple studies have tried to pin down what makes a belly button look “right,” and some consistent findings have emerged. A review of the literature found broad agreement that a smaller navel is generally perceived as more attractive, with reported ideal sizes ranging from about 0.6 to 3.0 cm across different studies.1PubMed Central. Does Size Really Matter? A Review on How to Determine the Optimal Umbilical Size During an Abdominoplasty The consensus leans toward a vertically oriented shape, though the ideal differs between men and women. In women, a small vertical oval with some hooding at the top is generally preferred. In men, a horizontal oval tends to score better aesthetically.2PubMed Central.

Position matters too. The navel sits roughly at the midpoint of the torso, but the precise ratio of the distance from the bottom of the breastbone to the navel versus the navel to the lower abdominal crease has been measured at about 1.68 in men, placing the male navel slightly below the average female position.3PubMed Central. Ideal Male Umbilicus: An Observational Study of Surface Anatomy and Introduction to the SHAPE Classification One study proposed that the optimal navel length should be about 5% of the total distance from the breastbone to the vulva in women.4PubMed Central. Does Size Really Matter? A Review on How to Determine the Optimal Umbilical Size During an Abdominoplasty These numbers give surgeons benchmarks, but there is no universal standard. The absence of a single agreed-upon measurement system across published studies is itself a telling detail about how subjective this area remains.
Why People Have It Done
The reasons for umbilicoplasty fall into two broad camps: cosmetic preference and medical necessity. On the cosmetic side, some people are self-conscious about a navel that protrudes (an “outie”), looks stretched after pregnancy or weight changes, or has scarring from a piercing. Standalone cosmetic umbilicoplasty is a relatively quick procedure, often done under local anesthesia, and the recovery is straightforward compared to more extensive abdominal surgery.
The medically motivated cases are more varied. Abdominoplasty, commonly known as a tummy tuck, is by far the most common context. During a standard tummy tuck, the surgeon separates the belly button stalk from the surrounding skin, pulls the abdominal skin flap downward to remove excess tissue, and then creates a new opening for the navel to emerge through. This step is itself an umbilicoplasty.5PubMed Central. Umbilical reconstruction: different techniques, a single aim Other scenarios include reconstruction after hernia repair, after removal of abdominal tumors, following massive weight loss surgery, or to address congenital abdominal wall defects in children where the original belly button was lost or never properly formed.6PubMed Central.

How the Surgery Works
There is no single “umbilicoplasty technique.” A review of surgical methods illustrated at least eight distinct approaches, noting that the best ones balance operating-room efficiency with long-term cosmetic results.7The American Journal of Cosmetic Surgery. The Cosmetic Umbilicus: A Review of Aesthetic Features and Surgical Methods The choice depends on what exists already. When the navel stalk is intact and healthy, surgeons preserve it and simply reshape the surrounding skin opening. When the original navel is too scarred or malformed to use, three more complex reconstruction procedures may be needed to build one from scratch.
In a typical tummy tuck context, the navel stalk stays anchored to the deep abdominal wall throughout the operation. The surgeon carefully dissects around the stalk, keeping a generous cuff of fat around it to protect its blood supply.8PubMed Central. Post-Caesarean and Post-Laparotomy Abdominal Wall Reconstruction (Tummy Tuck) For Aesthetic and Functional Restoration in A Low Resource Setting: A Case Report Once the abdominal skin has been pulled down and trimmed, a new hole is cut in the skin flap at the correct position, and the navel is brought through. One technique uses a V-shaped incision in the flap along with anchoring stitches from the deep abdominal wall connective tissue to the navel stalk, which helps create a natural inward contour.9PubMed. Optimizing Abdominal Contours: A Novel Approach to Abdominoplasty
The shape of the skin incision matters a great deal for the final look. Common options include round, oval, inverted-U, star-shaped, and so-called “Mercedes-Y” patterns. Each produces a different scar geometry and a different tendency toward long-term shape changes as the scar matures. In a study comparing the round method against the inverted-U flap technique, surgeons rated both methods equally, but patients strongly preferred the inverted-U flap. Only 15% of patients in the inverted-U group could tell they had undergone umbilicoplasty, compared to 58% in the round-incision group. None of the inverted-U patients preferred their old belly button, while a quarter of the round-method patients did.10PubMed. Patient satisfaction with two different methods of umbilicoplasty
The Blood Supply Problem
The belly button has a richer blood supply than most people would guess, and understanding it is one of the key challenges in umbilicoplasty. An anatomical study found that the navel receives blood from three distinct deep sources beyond the general skin blood supply: branches from the deep inferior epigastric arteries on both sides, the round ligament of the liver, and the remnant of the umbilical artery from fetal life.11PubMed. Arterial vascular anatomy of the umbilicus A separate dissection study confirmed that most people have four distinct blood vessels running into the navel stalk in a V-shaped pattern.12Journal of Plastic, Reconstructive & Aesthetic Surgery. Arterial vascularisation of the abdominal wall with special regard to the umbilicus and its surgical importance
This anatomy has direct surgical consequences. When a tummy tuck involves lifting only one side of the abdominal muscle, the other side continues to feed the navel generously. But when both sides are disrupted, the blood supply drops to just the small vessels from the ligament remnants, and the risk of the navel losing circulation rises sharply.13PubMed. Arterial vascular anatomy of the umbilicus This is why surgeons are so careful to preserve a fat cuff around the navel stalk during dissection. That padding contains the small backup vessels that can mean the difference between a healthy navel and one that dies from lack of blood flow.
Complications and How Surgeons Minimize Them
Umbilicoplasty complications are generally uncommon, but they span a recognizable range. A systematic review of reconstruction techniques during abdominoplasty found that necrosis, where part or all of the navel tissue dies, occurred at rates between 0% and 4% depending on the technique used. Some methods like the Mercedes-Y and certain structured flap approaches had no reported necrosis at all, while modified anatomical and other flap-based methods sat in the 2% to 4% range.14Innoscience Journal. Umbilical Reconstruction Techniques in Abdominoplasty: A Systematic Review of Aesthetic Outcomes and Complications Retraction or wound separation was more common in simpler techniques like basic oval or circular incisions, where rates reached 6% to 10%, compared to 3% or less in techniques that used deeper anchoring stitches.15Innoscience Journal. Umbilical Reconstruction Techniques in Abdominoplasty: A Systematic Review of Aesthetic Outcomes and Complications
A study of 49 patients who underwent a novel umbilical reconstruction technique reported a 4% overall complication rate: one patient had partial separation of the umbilical knot and one experienced navel necrosis, while 96% had no complications.16PubMed. Refining Abdominoplasty: A Novel Technique for Umbilical Reconstruction In another study using hyperspectral imaging to monitor blood flow after surgery, marginal wound necrosis appeared in four patients, but none required revision specifically for poor blood flow.17JPRAS Open. Impact of umbilical fixation on perfusion in abdominoplasty: A hyperspectral imaging study
Stenosis, where the navel opening narrows and distorts over time due to scar contracture, is a subtler problem. Because every person’s healing and scar remodeling process differs, a navel that looked perfectly sized at first can shrink into a tight, misshapen slit months later. Circular incisions are particularly prone to this because the scar contracts evenly inward from all directions. One approach to preventing stenosis uses an inferiorly based skin flap with an inverted-U design, which interrupts the circular scar and reduces contracture. In a series using this technique along with a foam earplug as a temporary stent during healing, the final navel size ranged from 1.8 to 2.2 cm, and both surgeons and patients reported full satisfaction with the size.18PubMed Central. Umbilicoplasty: A Simple Method to Prevent Umbilical Stenosis in a Tummy Tuck No standardized method for managing stenosis exists, though scar revision and stenting have both been described as options.19PubMed Central.

Building a Belly Button from Nothing
When the original navel has been completely lost or was never there, surgeons perform what is called neoumbilicoplasty: creating a new belly button from the surrounding tissue. This is a different challenge than reshaping an existing one, because there is no stalk to anchor to and no natural depression to work with. Several creative solutions exist. The “four flaps technique” elevates four small skin flaps from the tissue adjacent to the planned site, folds them inward, and stitches them together to create depth and a natural-looking hood at the top.20PubMed Central. Four flaps technique for neoumbilicoplasty A two-step approach first places deep stitches to create a soft-tissue indentation, then uses an inverted-V incision sewn to create the visual illusion of a belly button.21PubMed Central. A Two-step Technique for Neo-umbilicoplasty in the Abdominal Reconstructive Population
A more recent method called the “house-roof” technique uses a six-step process to construct a navel. Satisfaction in that series was high, with 96% of patients and the surgeon reporting significant satisfaction on a standardized aesthetic improvement scale measured 90 days after surgery.22PubMed Central. House-roof Neoumbilicoplasty: Six-step Procedure for a Natural Navel The “house-roof” designation also showed 0% necrosis in the systematic review mentioned earlier, placing it among the safer technique profiles.
After Massive Weight Loss or Previous Abdominal Surgery
People who have lost very large amounts of weight, whether through bariatric surgery or other means, often face a particular dilemma with their belly button during body-contouring procedures. The navel may have become severely drooped or stretched, and scar tissue from prior surgeries like cesarean sections or hernia repairs may have compromised its blood supply. In these situations, the surgeon sometimes has to accept that the original navel cannot be saved. Umbilical necrosis is highly likely when the tissue has been previously operated on or when the navel has descended far from its anatomical position.23Journal of Visceral Surgery. Body reshaping surgery after massive weight loss
Interestingly, experience in this population has shown that patients are rarely bothered by losing their belly button entirely and only occasionally request a secondary reconstruction.24Journal of Visceral Surgery. Body reshaping surgery after massive weight loss When reconstruction is desired, a neoumbilicoplasty can be performed either at the same time as the abdominoplasty or as a second-stage procedure later. The patient should be told beforehand that umbilical sacrifice is a real possibility, so the conversation happens before surgery rather than after.
Pediatric Navel Reconstruction
Children born with abdominal wall defects often end up without a recognizable belly button after their initial repair. Older techniques for recreating the navel in these cases relied on purse-string sutures that bunched the skin into a mound, which did not look particularly convincing, or were limited to defects smaller than about 5 cm.25Journal of Pediatric Surgery. Advancement flap umbilicoplasty after abdominal wall closure: Postoperative results compared with normal umbilical anatomy More refined flap-based techniques have since expanded the options.
A recent study establishing reference measurements for the navel in boys aged 1 to 14 found that the belly button grows steadily throughout childhood, adding roughly 0.9 mm in height and 0.75 mm in width per year at the 50th percentile. In younger children, the navel tends to be wider than it is tall, but around age 4 the dimensions equalize, and during puberty the navel becomes taller than wide, developing the vertical shape seen in adults.26PubMed Central. Umbilical morphometry and centile curves in boys aged 1-14 years: Establishing reference values for umbilical reconstruction These growth curves give pediatric surgeons age-appropriate size targets when planning a reconstruction, rather than guessing at what looks “about right” for a given child.
Keloids and Piercing Scars
Not every belly button concern calls for a full surgical procedure. Navel piercings, which became mainstream in the 1990s, leave a legacy of scarring in a meaningful number of people who later decide to remove them. Most piercing scars are cosmetically minor and fade over time, but in people prone to keloid formation, the scar can grow into a raised, firm mass that is much larger than the original wound.
Keloids in the umbilical region are notoriously stubborn. Surgical removal alone carries a high recurrence rate, because the act of cutting triggers the same overactive healing response that created the keloid in the first place. A case report documented successful treatment of a recurrent umbilical keloid in a 31-year-old woman using a combination of intralesional cryotherapy followed by injections of a steroid and botulinum toxin. The treatment produced high patient satisfaction with no recurrence.27PubMed Central. Intralesional cryotherapy with triamcinolone and onabotulinumtoxinA injections for umbilical keloid: A case report This multimodal approach, treating the keloid from several angles rather than just cutting it out, reflects the broader shift in scar management toward combination therapies.
For people considering a cosmetic umbilicoplasty who know they scar aggressively, this is worth discussing with the surgeon beforehand. Any incision in the navel area can potentially trigger keloid formation, and the risk may outweigh the cosmetic benefit of surgery. Preventive measures like silicone sheeting, pressure therapy, or early steroid injections into the healing scar can reduce but not eliminate the chance of keloid development.
What Patient Satisfaction Actually Looks Like
Across the published literature, satisfaction rates after umbilicoplasty are consistently high, though the numbers depend on which technique was used and how satisfaction was measured. The house-roof neoumbilicoplasty reported 96% satisfaction at 90 days.28PubMed Central. House-roof Neoumbilicoplasty: Six-step Procedure for a Natural Navel The novel reconstruction technique in a 49-patient series also reported high satisfaction, with patients highlighting the natural appearance of the result.29PubMed. Refining Abdominoplasty: A Novel Technique for Umbilical Reconstruction The earplug-stenting method achieved 100% satisfaction from both surgeon and patient on final navel size.30PubMed Central. Umbilicoplasty: A Simple Method to Prevent Umbilical Stenosis in a Tummy Tuck
The most revealing data, though, comes from the comparative study of the round method versus the inverted-U flap. Surgeons thought both methods produced equally good results, but patients disagreed. The inverted-U method produced navels that looked natural enough that 85% of patients could not tell they had been operated on. The round method left visible enough scars that the majority of patients recognized the navel as surgically created.31PubMed. Patient satisfaction with two different methods of umbilicoplasty The gap between surgeon assessment and patient perception is a recurring theme in cosmetic surgery research, and it highlights why the choice of technique matters beyond what looks good on the operating table. The scar pattern left by the incision design determines much of the long-term cosmetic outcome, and patients live with that outcome far longer than the few minutes a surgeon spends evaluating it in the clinic.
