Wise-Pattern Breast Reconstruction

Modification Using Alloderm and a Vascularized Dermal-Subcutaneous Pedicle

Abstract

Immediate implant-based breast mound reconstruction offers many advantages over staged implant reconstruction techniques. For large volume breast reconstruction, a Wise-pattern skin resection may provide very good aesthetic results; however, the submuscular implant pocket is inadequate to cover the inferior pole of the breast. In this patient population, the risk of implant exposure from T-point breakdown is significant. We present our technique of Wise-pattern breast reconstruction using AlloDerm (LifeCell, Branchburg, NJ) and a vascularized dermal-subcutaneous pedicle (DSP) to augment the volume and quality of immediate breast implant coverage, particularly in the area of the T-point suture lines.

We reviewed a series of 20 consecutive patients with large breasts who were treated with an immediate implant reconstruction of greater than 400 mL volume using the Wise-pattern with DSP. Preoperative and postoperative 3-dimensional surface scan studies were performed to evaluate breast symmetry.

The average volume of breast reconstruction in this study group was 458 mL. T-point breakdown occurred in 5 patients (25%). These patients were treated with local wound care and healed with an excellent aesthetic result. None of these patients required implant removal, implant exchange, or operative debridement. Pre- and postoperative 3-dimensional surface scan analysis of these patients demonstrated comparable differences between the affected and unaffected sides in women undergoing immediate breast implant reconstruction when compared with a matched group of patients undergoing 2-stage breast reconstruction with tissue expanders.

Wise-pattern skin-reducing mastectomy is an excellent strategy to provide an aesthetically pleasing, immediate implant breast reconstruction. This technique provides breast symmetry that is at least comparable to that of tissue expander-based, staged implant reconstructions. The reliability of the Wise-pattern technique is significantly improved with the addition of AlloDerm to the muscular pocket and a vascularized DSP to preserve the integrity of the reconstruction in the presence of T-point breakdown.
