"Autologous Breast Dermal Filler": A Novel Technique for Breast Reconstruction After Nipple- or Skin-Sparing Mastectomy in Pubertal Gigantomastia.

BACKGROUND

For females in puberty, mastectomy caused by pathological gigantomastia usually brings significant psychological problems. Appropriate immediate breast reconstruction method is necessary.

OBJECTIVES

The aim of this study is to present a novel method of breast reconstruction that requires neither implants nor donor-site sacrifice.

METHODS

All patients who were diagnosed with pathological gigantomastia and indicated for nipple-sparing or skin-sparing mastectomy (NSM or SSM) were selected. All extra skin was de-epithelialized, followed by NSM or SSM through a vertical incision on the lower pole of the breast. Then, a skin and dermal envelope in all directions was formed. Whether to preserve the nipple-areolar complex depended on its perfusion. The dermal flap was folded inward to serve as the "autologous dermal filler" and reconstruct the breast. A second surgery of inframammary fold elevation for larger projection was performed at least 6 months. Follow up for at least 1 year and record complications as well as pre- and postoperative BREAST-Q Scores.

RESULTS

A total of 11 breasts were included. Four (36.4%) were NSM and seven (63.6%) were SSM. Nipple to sternal notch distance in NSM and SSM was 32.3±9.1cm and 35.1±4.4cm, respectively. No complications occurred, while one breast with NSM showed nipple upward displacement. The BREAST-Q indicated significant postoperative improvements in breast satisfaction (20.5 ± 11.3 vs 80.2 ± 10.4) and psychosocial well-being (23.4 ± 8.9 vs. 81.4 ± 11.3).

CONCLUSIONS

Preliminary study demonstrated the efficacy and long-term safety of "autologous breast dermal filler." For adolescents, it is a less invasive autologous breast reconstruction method, or transitional plan for further adjustment in adulthood.
