Buttock Implants

Buttock implants are a considerably more troublesome operation, and comparing the two misleads patients badly. The incision sits in the crease between the buttocks next to a source of contamination, and the pocket is inside a muscle that works constantly and is sat upon, so infection, wound separation and displacement all occur far more often.

The devices themselves are also different: buttock implants are solid silicone elastomer rather than gel, so they cannot leak or rupture and need no monitoring. What fails is the wound, the pocket and the position rather than the implant, and revision is common rather than exceptional.

Buttock implants sit inside the gluteus maximus muscle in the standard technique, which covers the implant edges and keeps it away from the sciatic nerve running beneath. Some surgeons place them beneath the fascia covering the muscle instead, which hurts less and allows a larger implant.

The trade is visibility. A subfascial implant is more easily felt and sometimes seen, particularly in a lean patient, while an intramuscular one is better disguised but limited in size by what the muscle can hold and more painful to recover from. Ask which is proposed and why.

Both implants go through a single incision in the crease between the buttocks, usually 5 to 7 centimetres long, so no scar sits on the buttock itself and nothing shows when standing.

The problem with that location is healing rather than appearance. The crease is warm, moist, constantly moving and difficult to keep clean, so partial separation of the wound is common and can take weeks of dressings, frequently leaving a wider scar in that section.

Buttock implants hurt significantly, and more than most implant surgery, because the standard technique splits a large working muscle and places a device inside it. Walking, standing up and stairs all recruit that muscle, so the first 2 weeks are genuinely uncomfortable.

Prescribed painkillers are usually needed for a week or more, and a 2 night hospital stay is appropriate rather than cautious. Patients who have had breast implants consistently report this as a much harder recovery, which is worth knowing before rather than after.

An infected buttock implant almost always has to be removed. Bacteria on an implant surface are protected from antibiotics in a way that infection in tissue alone is not, and in this location the bacterial load is higher than almost anywhere else implants are used.

Replacement is possible after several months once everything has settled. Report spreading redness, increasing pain, fever, or any discharge from the midline wound the same day rather than waiting, because early treatment occasionally saves an implant that would otherwise be lost.

The sciatic nerve runs beneath the gluteal muscle, and a pocket made too deep can irritate or compress it, producing pain, numbness or tingling down the leg. It is uncommon and it is one of the reasons the intramuscular plane is chosen carefully rather than casually.

Most nerve symptoms after buttock implants settle over weeks as swelling resolves. Pain shooting down the leg that is worsening rather than improving should be reported promptly, since a malpositioned implant occasionally needs repositioning to relieve it.

Very little sitting for the first 2 weeks, and then only on a cushion that supports the thighs rather than the buttocks, for several weeks after that. The restriction protects the midline incision, which separates easily, as much as the implant pocket.

It governs the flight home, which is not usually cleared until around day 14 for this reason. Take a proper cushion, stand up regularly during the flight, and expect prolonged sitting at a desk to remain uncomfortable for around a month.

Buttock implants are solid silicone elastomer with nothing inside to leak, so they do not degrade and need no routine replacement or monitoring scans. Many patients keep the same implants indefinitely.

What brings them out is mechanical or infective. Displacement, rotation, capsular contracture and infection are the reasons for revision, and they cluster in the first year rather than appearing later. An implant that has been comfortable and well positioned at 12 months is unlikely to cause trouble afterwards.

Often, in a lean patient, particularly at the outer or lower edge where muscle cover is thinnest. An intramuscular implant is better disguised than a subfascial one, but neither is undetectable on examination.

Whether it is visible is a separate question and usually depends on size. A correctly sized implant follows the shape of the buttock; one too large for its pocket shows its outline and is more likely to displace. Grafting fat around an implant softens the transition where donor fat is available.

Removal is a shorter and simpler operation than placement, through the same midline incision, and the buttock returns close to its previous shape once swelling settles. That reversibility is a genuine advantage over grafted fat, which cannot be selectively removed.

Where a patient wants the volume back afterwards, fat grafting is the usual route, generally at a second operation months later once the pocket has closed and settled. Doing both at once risks the graft failing in a space that has just held an implant.

For most patients fat grafting is better than buttock implants, and any consultation should establish that first. Fat grafting looks and feels more natural, has no device to become infected or displace, narrows the waist at the same time, and has a considerably easier recovery.

Implants are the answer where there genuinely is not enough donor fat, which is a real situation for lean patients rather than an excuse. A surgeon who offers implants without assessing whether you have fat to harvest is skipping the more important question.

Ask how many buttock implants they place each year, because this is an uncommon operation and volumes vary enormously. Ask which plane they use and why. Then ask directly for their infection, wound separation and revision rates.

A surgeon who gives you realistic figures, which will sound high compared with breast surgery, is being straight with you. One who implies these complications are rare either does few of these operations or is not telling you what the literature says. Ask to see results at 12 months, standing.

Buttock implants are solid or semi-solid silicone elastomer, not the gel used in breast implants. There is no filling, so they cannot leak or rupture, they do not degrade, and no monitoring scans are needed.

They are also firmer than breast implants by design, because they have to withstand the pressure of sitting and the constant contraction of the muscle around them. That firmness is part of why they feel different from grafted fat and why a large implant is more easily detected.

Buttock implants do not trigger metal detectors, since solid silicone contains no metal. Body scanners occasionally show a difference in density, which is resolved by saying what it is.

They are safe with MRI, CT and ultrasound and do not interfere with imaging of the pelvis or hips for unrelated reasons. Mentioning them to a radiologist is still sensible, so an unfamiliar shape is not investigated as something else.

Buttock implants last indefinitely and need no routine replacement, because there is nothing inside them to fail. Many patients keep the same implants for life.

What ends an implant’s life is the pocket rather than the device: infection, displacement, rotation or capsular contracture. Those cluster in the first year, so an implant that has been comfortable and correctly positioned at 12 months is much less likely to cause trouble later.

Buttock implants made of solid silicone elastomer do not rupture, because there is no shell containing a filling. A fall or a heavy landing will not split one the way it might a gel breast implant.

What a significant impact can do is displace an implant within its pocket, particularly in the first weeks before the capsule has formed. That is one reason lower body exercise and contact activity wait 6 to 8 weeks rather than resuming as soon as the pain settles.

In a lean patient a buttock implant border can sometimes be seen when the gluteal muscle contracts or when bending, particularly where the implant is large for its pocket or placed beneath the fascia rather than inside the muscle.

Intramuscular placement disguises the edges better, at the cost of more pain and a smaller maximum size. Grafting fat around the implant, where any donor fat exists, softens the transition further and is worth asking about even in a patient who is having implants because they are lean.

Exercise after buttock implants means walking from the first day, light cardiovascular work at around 4 weeks, and lower body training at 8 weeks or later. Squats, lunges and anything loading the gluteal muscle directly wait longest, because the implant sits inside that muscle.

Returning early risks displacing the implant before the capsule has formed around it, which is a leading reason for revision. Ask for a written timetable by exercise type, since a general clearance to return to the gym is interpreted generously by most patients.

Different sized buttock implants can be used on each side, and custom implants are made for marked asymmetry from previous surgery, injury or a developmental difference.

Fat grafting corrects asymmetry more precisely, because volume can be placed exactly where it is needed rather than in a fixed shape. Where a patient has both an asymmetry and enough donor fat, grafting is usually the better tool, and an implant is reserved for those with nothing to harvest.

Most patients describe recovery from buttock implants as a deep, heavy soreness rather than sharp pain, worst when standing up from a chair or climbing stairs, because those movements recruit the muscle the implant sits inside. It eases substantially over 2 weeks.

The harder part is the restriction. Not sitting, sleeping face down, watching a wound you cannot see, and moving carefully for a month is wearing in a way the pain is not. Patients who have had breast implants consistently say this is a different order of recovery.

Buttock implants can usually still be placed, though previous grafting changes the tissue. Scarring from an earlier operation makes the planes less distinct and the pocket harder to create cleanly, so it is technically more demanding than a first-time placement.

The reverse order is more common and generally preferred: implants first where projection is needed, then fat grafted around them later to soften the edges. A surgeon should explain which sequence they are proposing and why.

Smoking is the biggest risk factor for buttock implant infection, followed by anything that compromises the midline wound in the first weeks. Nicotine reduces the blood supply that fights infection and heals the incision, and this wound is already in the worst location on the body for contamination.

Beyond that, wound separation itself raises the risk, because an open wound next to an implant is a route in. That is why the sitting restriction and careful wound hygiene are not fussiness but the main defence against losing the implant.

Follow the clinic’s wound instructions after buttock implants to the letter, keeping the area clean and dry, because this incision sits closer to a source of contamination than any other in aesthetic surgery. Most surgeons give specific washing and dressing routines rather than general advice.

You cannot see the wound yourself, which is the practical difficulty. Arrange for someone to look at it regularly and photograph it, and establish before you travel who at home can review it if the skin edges start to separate.
