Pre-pectoral Tissue Expander and Acellular Dermal Matrix for a Two-stage Muscle Sparing Breast Reconstruction

Pre-pectoral Tissue Expander and Acellular Dermal Matrix for a Two-stage Muscle Sparing Breast Reconstruction: Indications, Surgical Technique and Clinical Outcomes With Histological and Ultrasound Follow-up

The aim of the research is to evaluate clinical outcomes of a two stage muscle sparing prepectoral breast reconstruction using tissue expander (TE) entirely covered by an ADM. The authors aim to report surgical indications, technical tips, clinical and histological outcomes with the final objective of delineate a decision-making algorithm for immediate prosthetic breast reconstruction.

Inclusion Criteria:

• unilateral or bilateral mastectomy followed by two stage breast reconstruction with subcutaneous tissue expander and Acellular Dermal Matrix (ADM)
• risk-reducing mastectomies followed by two stage breast reconstruction with subcutaneous tissue expander and ADM

Exclusion Criteria:

• partial or total submuscular tissue expander placement,
• tissue expander placement in conjunction with latissimus dorsi muscle flap or without ADM, -delayed reconstructions
• previous breast surgery
