What is fat transfer to the face?

Fat transfer (fat grafting) is a dynamic procedure, which has gained immense popularity to augment various parts of the body. The technique involves aspirating fat through a special small diameter cannula. The therapeutic effect of stem cells present in fat cells is an additional benefit that has an emerging role in tissue regeneration and wound healing.

The removed fat is then treated to remove oil, blood and excess water. This leaves concentrated fat cells, which are gently re-injected to fill out the desired area on the face. Unlike filler, the fat is completely natural and as it is from your own body, any allergy risks are removed. Fat has additional benefits in improving skin texture and blood supply resulting in a true facial rejuvenation. This procedure can be used on its own or more commonly in combination with a face and neck lift.

The whole concept is based on ‘structural fat grafting’. Fat cells injected by this special method lie in different tissue planes and can receive an individual blood supply. This results in the injected fat remaining for the longer term.

It is estimated that between 40% to 70% of the fat injected survives long-term, for which we overcompensate at the initial surgery. However, there is a maximum amount of fat that can be injected in any one procedure, therefore further sessions may be required. Facial lipofilling, can not only fill defects and improve contour, but also regenerates skin to offer a more youthful appearance.

The technique involves aspirating and collecting fat through a small diameter cannula. The harvest technique is the same as for liposuction. You can select the donor site, but it is best taken from an area of diet resistant fat such as the abdomen, hips or thighs.

The fat is then injected into the area of concern with a fine needle so there is no visible scar. In the face, fat is often injected into nasolabial folds (between the nose and the corner of the mouth), marionette lines (from the corner of the mouth towards the chin), nasojugal groove (groove under the eye), perioral fine lines, cheeks and lips. This process is time consuming and relies on delicate fat handling and careful reinjection.

The procedure is normally carried out general anaesthetic (you will be fully unconscious) and takes about 40 minutes to perform. This is normally carried out as a day case, so you do not need to stay overnight in the hospital. However, if you have the fat grafting as part of another surgery you may be required to stay in hospital a little longer.

Having cosmetic surgery should be a very positive experience. Complications are infrequent and usually minor. However, all surgery has risk, and it is important that you are aware of possible risks and complications. All the risks will be discussed in detail at your consultation. However, if you have further questions or concerns, please do not hesitate to discuss them with me.

Decisions about cosmetic surgery should never be rushed.

These risks can be divided into those specific to the surgery and those that relate to the anaesthesia.

General Anaesthetic risks: An anaesthetic is very safe, however, should a complication arise, the relevant medical expertise is immediately available to deal with this.

The risks increase if you have certain medical problems, which will be discussed at length during the consultation. The risks include:

  • Unintended intraoperative awareness, which is very rare.
  • Dizziness and nausea.
  • Sore throat.
  • Damage to teeth or mouth.
  • Nerve injury due to body positioning.
  • Allergic reaction or anaphylaxis.
  • Malignant hyperthermia, which is a rare life-threatening condition.

The anaesthetist will go through these risks in more detail prior to your surgery.

Scars: Apart from a needle mark like having blood taken, there will not be any scars. The scars at the donor site are approximately 3mm in size. These are hidden in the skin crease and should be barely perceptible. However, some patients heal with noticeably thickened, thin or stretched scars.

There will be no scars on the face, as the fat is injected with a needle.

Bruising and swelling: This is very common on both the recipient and donor sites and the bruising may take a couple of weeks to settle.

Infection: This is rare but may require a course of antibiotics to treat should an infection occur.

Contour irregularities: It is possible to have indentations or laxity of the skin following this procedure. Massaging the area(s) should resolve this but occasional further surgery may be required.

Fat necrosis: If some of the fat does not receive a blood supply it will die and gradually be re-absorbed. This can sometimes leave a lump that cannot be seen but can be felt. Massaging should resolve this but occasionally a procedure to remove the lump may be required.

Fat loss: Of the fat that is injected, 40% to 70% of this should ‘take’ and become permanent. The remaining fat will simply ‘melt away’ (re-absorb) over the next few weeks. If at this stage, you would like more volume, this can be performed approximately 12 or more weeks later.

Fat cysts: After fat transfer, these can sometimes occur but are uncommon on the face. Most cysts can be aspirated with a needle if they are problematic.

Fat embolus: When fat is injected near the eye, there is a very small risk of it being injected into the blood vessels themselves. If this does occur, then the fat could become lodged in the blood vessels supplying the eye. This could cause permanent blindness. Whilst this is possible, the injection needles are blunt and inject fat from the side rather than the tip to reduce the risk of an embolus.

Further fat transfer procedures: These are sometimes required to give the desired result as only a certain amount of fat can be injected during one operation. If you would like more volume, this can be performed any time after 12 weeks post-surgery.

Further liposuction: This may be necessary to achieve the desired result. Only a certain amount of fat is removed at one operation (1 litre). However, if you wish additional liposuction, then this can be performed at the same time.

Damage to internal structures: Liposuction is performed in the superficial layer of fat underneath the skin. As the cannulas are blunt, they are very unlikely to damage any important structures. However, if there is a hernia or weakness of the abdomen, then damage may be possible; this is very unlikely.

Deep Vein Thrombosis/Pulmonary Embolism (DVT/PE): Following any surgical procedure it is possible to develop a blood clot in your legs, which could potentially break off and travel to your lungs. If the blood clot is large enough, it could prove fatal.

The overall risk for cosmetic surgery is less than 1%, but to reduce any risks of a DVT/PE, you will be provided with special stockings to wear in bed together with a blood thinning injection, if you are not mobile or have previously had a DVT or PE.

All the risks outlined above will be discussed in more detail at your consultation with me. However, if you have further questions or concerns, please do not hesitate to ask.

Your incisions used for fat harvest are closed with dissolvable sutures, which do not require removal.

I use a waterproof dressing, which will be removed after one week when everything should have healed.

You can shower as soon as you like after surgery, and you will be given spare dressings in case they become wet and need changing. I do not recommend bathing or swimming for 1 week after surgery.

You will not be able to drive yourself home from hospital and, ideally, you should have someone to stay with you for a few days to assist you. If you have any concerns during this period, do contact the Clinic for advice.

Before you are discharged from Hospital you will be given a follow up appointment to see the nurse after one week post-operatively.

Initially, the area injected may seem larger than you expected. This is normal and it is partly due to swelling. It takes time for everything to settle down. The volume is likely to reduce as the swelling and bruising resolves and some of the fat absorbs.

It takes approximately 12 weeks to assess the result of your surgery. Thereafter, you can decide if you would like more volume.

Scar Advice
Once the dressings are removed, I recommend that you massage the incisions, using small circular motions at least twice a day for 5 minutes. You can use any moisturising cream of your choice and apply firm pressure until it blanches.

The scars will also benefit from silicone scar gel (ScarAway® or Kelo-Cote®) twice a day, which will soften and fade them, as well as applying sunblock for 12 months to provide sun protection.

The ScarAway® can be purchased from Healthcare Pharmacy at Governors Square in Grand Cayman.

Recovery times vary from one person to another. Depending on the amount of bruising and swelling, you can return to work the next day. If it is combined with a facelift, then most patients return after approximately 1 to 2 weeks. If you have any concerns during this period, do contact the clinic for advice.

You will have a moderate degree of swelling and possible bruising after the operation, but this will settle over 1-2 weeks. Most patients will be able to go home the same day, depending on whether you have the fat grafting alone or as part of another surgery.

For self-funding patients, surgical fees are a combination of the hospital costs, the surgeon and anaesthetic fees and any consumables. I do not charge an additional fee for post-op appointments. The fee is based on the surgical time rather than procedure. This means that the surgery costs are calculated fairly, and patients with complex needs may have higher costs than routine patients. You will be given a quotation for surgery within 48 hours of your consultation.
