Fat Grafting Lumps & Calcification

We only remove the defective tissue—necrotic fat, oil cysts, and calcifications. Healthy surviving fat is preserved. The volume occupied by necrotic material was not providing useful aesthetic volume anyway (it was creating distortion), so most patients see improved contours rather than volume loss.

Necrotic tissue that has been removed does not grow back, though any residual areas may need further treatment. The healthy fat that survived the original grafting procedure remains stable long-term. New complications would only arise from additional fat grafting procedures.

Lumps form when injected fat cells cannot establish blood supply quickly enough and undergo necrosis. Common contributing factors include injection of large boluses exceeding the tissue's vascular capacity, placement in poorly vascularized planes, rough fat processing, and individual patient healing factors. Even with optimal technique, some degree of fat necrosis is expected—clinically significant lumps occur in 5-15% of cases.

Yes, most facial fat calcifications can be treated with ultrasound-guided micro-cannula extraction. We mechanically break down the calcified shell and aspirate the contents through a needle-sized entry point of about 2 mm. When calcifications are large or deep, such as those adherent to the periosteum, we treat them zone by zone over separate sessions, still through pinholes of about 2 mm, with no incision.

Oil cysts typically form within 1-3 months as necrotic fat liquefies. Calcifications develop later—usually 6-12 months—as the body deposits calcium around dead tissue. Some calcifications continue to enlarge and harden over 1-2 years. Early ultrasound detection allows treatment before calcification becomes extensive.

Minor contour irregularity is possible for larger lumps. After extraction there is a period in which the swelling settles and firmness gradually softens; we go through the details at your consultation. Our technique preserves all viable fat, minimizing contour impact. For significant volume loss, corrective fat grafting can be performed after complete healing.

Fat necrosis calcifications in the face can appear alarming on imaging and may trigger concern. They are benign, but we recommend ultrasound evaluation to characterize the mass and distinguish it from other pathology. Once confirmed as fat necrosis calcification, treatment is for cosmetic and comfort reasons rather than medical urgency.

Some firmness in the first 2-3 months after fat grafting is part of normal healing. However, if palpable lumps persist beyond 6 months, are growing harder, or cause visible asymmetry, they are unlikely to resolve spontaneously. Oil cysts don't absorb, and calcifications only harden further with time. A second opinion with ultrasound assessment can determine whether you're dealing with normal healing or complications that need intervention.

Adding more fat over existing necrotic tissue, oil cysts, or calcifications is counterproductive — the new fat faces the same vascularization challenges in tissue already compromised by the failed graft. At FILLER REVISION, we always classify and treat the existing complications first. Once the necrotic material is removed and healing is complete, corrective fat grafting in healthy tissue can be considered if needed.
