Key considerations
Fat grafting, also called autologous fat grafting or fat transfer, uses fat removed from one area of a person’s own body, prepared, and transferred to another area. The indication, available volume, processing method, and amount of volume retained vary from person to person. Planning therefore depends on clinical assessment, medical history, physical examination, and goals discussed during consultation.
The term nanofat generally refers to a particular preparation of processed fat used in selected settings. The word itself does not establish an indication, an outcome, or procedural safety. Its relevance must be assessed individually.
Clinical context
Fat grafting may be discussed for contour correction, reconstruction, selected irregularities, or in combination with other procedures. The decision depends on anatomy, tissue quality, the donor site, medical conditions, and the treatment objective.
No technique can predict that all transferred volume will remain. Some fat may be resorbed, and contour changes, asymmetry, nodules, oil cysts, or calcifications may occur. Additional assessment or further stages may be considered in some cases; this should not be understood as a promise or an individual recommendation.
Associated technologies
A consultation should address medical and surgical history, medications, allergies, tobacco use, weight changes, relevant tests, expectations, and alternatives. It is also important to clarify whether the proposal is isolated or combined with liposuction, reconstructive surgery, or another procedure.
Useful questions include: What is the purpose of the graft? Where will the fat be harvested? How will it be prepared and transferred? Which risks are most relevant for this body area? What setting is appropriate? How will follow-up be organized? Which warning signs require immediate contact with the team?
Risks, limitations, and safety
As with any surgical procedure, fat grafting may involve pain, swelling, bruising, bleeding, infection, sensory changes, irregularities, asymmetry, scarring, the need for revision, and anesthesia-related risks. Partial resorption, fat necrosis, oil cysts, and calcifications may also occur, depending on the site and technique.
Gluteal fat grafting requires specific attention. Medical societies recommend considering training, credentialing, an authorized facility, pre- and postoperative care, and technical safety measures. The ASPS joint statement emphasizes injection in a safe anatomic plane and, where required by applicable standards and clinical protocols, real-time ultrasound during gluteal injection [1].
Safety also depends on accessible follow-up and a plan for recognizing and managing complications. Travel, distance from the surgical team, facility conditions, and access to care should be discussed before making a decision.
Complementary resources
Technological resources may be considered as part of an individual assessment, depending on the indication, the team’s experience, the clinical setting, and applicable standards. They do not replace physical examination, anatomic planning, informed consent, or follow-up.
Resources that may be discussed include radiofrequency platforms and technologies for tissue contraction or coagulation, such as InMode’s IGNITE RF [2]; ultrasound-assisted liposuction systems, such as Solta Medical’s VASER [3]; and DEKA devices intended for specific medical applications [4]. Availability, indication, and use should be confirmed with the responsible clinician. The presence of a device does not mean that it is necessary or appropriate for everyone.

Frequently asked questions
Does grafted fat last forever?
Not necessarily. Volume retention varies and may be influenced by technique, location, blood supply, weight, and individual characteristics. The consultation should explain limitations and the possibility of change over time.
Can the required amount of fat be known in advance?
Planning can estimate volumes and sites, but available donor fat and tissue response may limit the proposal. An estimate does not predict volume or outcome.
Can fat grafting be combined with another operation?
It may be considered in some plans, but combining procedures changes operative time, recovery, risks, and follow-up needs. The decision should be individualized after a complete assessment.
What information should I bring to the consultation?
Bring a list of medications and allergies, relevant reports and test results, surgical history, information about medical conditions, and a clear description of what you want to understand. Additional photographs or tests should be requested and interpreted by the responsible team.
When should I contact the team after the procedure?
You should receive specific instructions and contact channels. Severe or worsening pain, shortness of breath, chest pain, fainting, fever, persistent bleeding, sudden worsening of swelling, or a significant change in skin color require prompt contact with the treating service or emergency care, depending on severity.
