Optimizing aesthetic outcomes in immediate prepectoral breast reconstruction using sharp-needle intradermal fat grafting: a clinical experience

Breast reconstruction after mastectomy is a critical aspect of breast cancer treatment. This retrospective study analyzes the efficacy and safety of the sharp needle intradermal fat (SNIF) technique in immediate two-stage prepectoral breast reconstruction (PPBR) after mastectomy. A retrospective cohort analysis was conducted on patients who underwent SNIF fat grafting after mastectomy and PPBR. Demographics, surgical indications, procedures, and complications were analyzed. The SNIF procedure involves the precise injection of small fat particles into the dermal layer, aiming to improve skin texture and correct minor surface irregularities. Sixty-seven patients underwent the SNIF procedure after PPBR. The mean age was 53.2 years, with a range of 33 to 71 years. No serious complications, such as infection or fat embolism, were observed. Minor complications included ecchymosis in 30 patients and redness with mild swelling in 13 patients, all of which resolved within a few days after surgery. Patients and surgeons reported satisfactory cosmetic results. The SNIF technique, using small-diameter fat particles injected intradermally, shows promise for improving aesthetic results and minimizing in two PPBR.
