Debulking Surgery After Muscular Paraffin Oil Injections: Effects on Calcium Homeostasis and Patient Satisfaction.

CONTEXT

Cosmetic paraffin oil injections can lead to granuloma formation, causing hypercalcemia and kidney failure.

OBJECTIVE

This study explores whether debulking surgery is an effective treatment for improving calcium homeostasis, inflammation, and clinical symptoms.

METHODS

In a retrospective study, we reviewed 33 patients undergoing debulking surgery. Changes in calcium, inflammatory markers, and renal function from baseline up to 12 months after surgery were assessed. Patients were interviewed after surgery.

RESULTS

The patients were 34.6 years of age (SD 6.9) and had 1104 grams (SD 591) of granuloma tissue removed following injection of 1329 mL (SD 803) paraffin oil 7.9 years (SD 3.2) earlier. Seventeen patients had hypercalcemia and experienced a significant decline in ionized calcium from 1.48 mmol/L (SD 0.16) at baseline to 1.33 mmol/L (SD 0.03) at 12 months (P < .002), although only 4 men (23.5%) became normocalcemic. Serum ferritin was reduced by 50% after 12 months (P = .048). Sixteen patients were normocalcemic and had no change in calcium homeostasis but experienced a 20% drop in serum ferritin levels (P = .025) after surgery. Fifteen patients completed all their planned surgeries within the study period and experienced a decline in serum ionized calcium (P = .031), ferritin (P = .011), and interleukin 2-receptor (P = .037). A survey showed that 55% of patients reported postoperative satisfaction scores of 10/10, and 59% of the patients reported reduced pain.

CONCLUSION

Surgery improved calcium homeostasis in a fraction of patients and reduced inflammation and subjective symptoms such as pain and mental well-being in a patient group left with few treatment options except high-dose prednisolone.
