[Techniques enhancement for tissue expander/implant two-stage breast reconstruction]

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Oncology

Background:

• Breast reconstruction is a critical component of post-mastectomy care.
• The tissue expander/implant two-stage approach is a common method for breast reconstruction.
• Optimizing techniques is essential for improving patient outcomes and aesthetic results.

Purpose of the Study:

• To evaluate the outcomes of breast reconstruction using enhanced techniques in the tissue expander/implant two-stage process.
• To analyze the impact of specific technical improvements on reconstruction success.
• To assess the role of autologous fat grafting as an adjunct procedure.

Main Methods:

• Retrospective analysis of 68 patients undergoing immediate or delayed two-stage breast reconstruction with tissue expanders/implants and fat grafting.
• Detailed review of surgical techniques including incision selection, expander placement, expansion principles, capsule management, prosthesis selection, and fat grafting.
• Objective evaluation of reconstruction outcomes using 3D surface imaging.

Main Results:

• The study included 25 immediate and 43 delayed reconstructions.
• Average tissue expansion duration was 7 months, with an average expansion volume of 372.8 mL.
• Autologous fat grafting averaged 119.3 mL.
• Excellent bilateral breast volume symmetry was achieved in both immediate (P<0.01) and delayed (P>0.1) reconstruction groups.
• Minor complications included two cases of tissue expander leakage and one secondary infection.

Conclusions:

• Enhanced techniques in two-stage tissue expander/implant breast reconstruction lead to favorable outcomes.
• Key improvements include transverse incisions, downward expander placement, rapid expansion, capsule release, sizer use for prosthesis selection, and autologous fat grafting.
• This refined approach effectively restores breast aesthetics and symmetry post-mastectomy.
