Rigottomia: The Rigottomy Fat-Grafting Technique, Explained

What is rigottomia?

The technique matters because it addresses the single biggest limitation of fat grafting: the quality of the tissue receiving the graft. Healthy tissue offers space and a blood supply; scarred or irradiated tissue offers neither. Rigottomia re-engineers that recipient bed so the body can accept and keep the graft, turning “inhospitable” tissue into a receptive scaffold. The name is the Italian form; “rigottomy” and the plural “rigottomies” are the English equivalents.

Origin: the Rigotti technique

The technique is named after the Italian plastic and reconstructive surgeon Gino Rigotti, whose work helped establish autologous fat as a regenerative material rather than a simple filler. In a landmark 2007 study published in Plastic and Reconstructive Surgery, Rigotti and colleagues treated breast-cancer patients with severe radiation-induced tissue damage using lipoaspirate transplantation, and documented symptomatic and structural improvement — including neovascularisation and tissue regeneration — attributed to the adipose-derived stem cells within the graft.¹ That insight — that fat could regenerate damaged tissue — is the conceptual foundation of rigottomia.

The percutaneous-release idea developed alongside two other pillars of modern lipofilling: Sydney Coleman’s structural fat grafting, which established the principle of placing fat in fine, evenly distributed parcels rather than large boluses,² and Roger Khouri’s work on external tissue expansion and recipient-site conditioning.⁴ Rigotti and Khouri are usually credited together with turning percutaneous rigottomy into standard practice for difficult recipient tissue.

The problem rigottomia solves

Grafted fat survives only if the tissue receiving it can provide two things: space to sit in and a nearby blood supply to feed it until new vessels grow in. Injecting fat under pressure into a stiff, contracted, poorly vascularised bed creates large pools of fat that the body cannot nourish — leading to reabsorption, oil cysts and fat necrosis. This is precisely the situation in mature scars, burns, irradiated skin and congenitally constricted tissue such as the tuberous breast.

How rigottomia works, step by step

The science & mechanism

Two complementary mechanisms explain why rigottomia improves outcomes. The first is mechanical: releasing the aponeurotic restraint makes the tissue compliant and expandable, so graft can be placed at low pressure and distributed widely instead of pooling. The second is biological: the controlled micro-injury and the released architecture increase the perfused surface area each fat parcel can draw nutrition from, while the adipose-derived stem cells and stromal-vascular fraction in the graft drive neovascularisation and tissue remodelling.¹

Imaging supports this. MRI studies of recipient-site conditioning show that pre-expanded, released tissue has increased vascularity and an enlarged fibrovascular scaffold, allowing higher graft volumes with better theoretical retention.⁵ In effect, grafting a released scaffold applies tissue-engineering principles — a vascularised matrix seeded with cells — to regenerate tissue that would otherwise require a flap.⁶

Clinical evidence

Rigottomia is a technique embedded within the wider fat-grafting literature rather than a single branded procedure, so its evidence base is best read across the studies that establish (a) the regenerative capacity of grafted fat, (b) the value of recipient-site conditioning, and (c) outcomes in the specific conditions it treats. The table summarises representative peer-reviewed evidence; figures come from separate studies with different populations and definitions, so they are indicative rather than a like-for-like comparison.

The overall picture is a consistent, mechanistically coherent body of evidence — much of it observational and single-centre — supporting recipient-site release and fat grafting for difficult tissue. As with all fat grafting, outcomes depend on technique, patient factors and staging, and high-quality randomised data remain limited.

Clinical applications

Tuberous & constricted breast

A tuberous breast is caused by a fibrous ring at the base of the breast that restricts development, producing a narrow, conical shape, an underdeveloped lower pole and often a herniated areola. Rigottomia releases that constricting ring through tiny punctures, freeing the lower pole to expand, and fat is then grafted to build volume and round out the shape — an approach described as a paradigm shift in tuberous-breast correction.⁷⁸ See our detailed article on rigottomia for tuberous breast and scar release.

Scars & burn contractures

Contracted scars and burns are the original home of the technique. Multiple tiny releases turn a stiff, tethered scar into a three-dimensional mesh, relieving tension, and seeding it with fat micrografts softens, expands and regenerates the tissue — with systematic-review evidence of improved scar quality and pliability.⁹ Related subcision-and-grafting protocols have been described specifically for burn-scar regeneration.¹¹

Breast reconstruction & irradiated tissue

After mastectomy — especially where radiotherapy has been given — the chest wall is often thin, tight and tethered. Rigottomia helps release and expand that tissue so it can accept fat grafting as part of a wider reconstruction strategy, building on Rigotti’s original work on regenerating irradiated tissue with fat.¹

Beyond the breast

The same release-and-seed logic is applied elsewhere in reconstructive and aesthetic surgery — for example, releasing the tethered scar of a repaired cleft lip before grafting to rebuild philtral contour.¹⁰ Wherever fibrosis restricts shape and volume, rigottomia offers a way to release it through the skin and rebuild with the patient’s own tissue.

Rigottomia & fat processing

A well-prepared recipient bed cannot rescue a poorly processed graft — the two are complementary levers. Gentle, low-pressure harvest and clean processing that removes blood, oil and debris while preserving adipocyte integrity and the regenerative stromal-vascular fraction give the seeded parcels their best chance to survive. Closed-system washing and concentration — the principle behind fat dialysis — is aimed at exactly this: cleaner, better-preserved fat to seed into the released matrix. For the harvesting and processing side of the technique, see our guides to fat grafting and recipient-site preparation.

Safety & recovery

Because rigottomia is performed through needle-sized entry points rather than open incisions, it avoids the long scars of flap or some implant techniques, and recovery is generally shorter than open surgery. It is frequently carried out under local anaesthesia with sedation. As with any procedure it is not risk-free: bruising, swelling, temporary firmness and — as with all fat grafting — partial reabsorption of the graft are possible, which is why more than one session is sometimes planned. Serious complications are uncommon in appropriately selected patients, but suitability is always an individual clinical judgement.

Key questions

Is rigottomia the same as percutaneous aponeurotomy?

Yes. “Percutaneous aponeurotomy” and “percutaneous fasciotomy” are the descriptive terms for the same manoeuvre — releasing the subdermal aponeurosis and fibrous septa through the skin. Combined with lipofilling it has been described as a regenerative alternative to flap reconstruction.⁶

How many sessions are needed?

Often more than one. A released bed can only support a limited amount of fat at once, and some grafted fat is naturally reabsorbed, so surgeons frequently stage treatment — particularly in scarred or previously irradiated tissue.

Does it leave scars?

The releases are made inside the tissue through needle-sized entry points, which typically heal to very small marks that fade over time.
