Splitting the Difference: Using Synthetic and Biologic Mesh to Decrease Cost in Prepectoral Immediate Implant Breast Reconstruction.

Abstract

Prepectoral breast reconstruction has minimized morbidity and dynamic deformities associated with submuscular implant-based breast reconstruction. However, reliance on implant coverage with acellular dermal matrix in immediate implant reconstruction remains limited by high material costs. The authors describe a technique in which anterior implant coverage in prepectoral reconstruction is split into acellular dermal matrix inferolaterally and synthetic, absorbable mesh superiorly. Use of acellular dermal matrix inferiorly provides coverage and reinforces the inframammary fold, whereas the absorbable mesh is trimmed and sutured to the acellular dermal matrix at the appropriate tension to support the implant and relieve pressure on mastectomy flaps. A retrospective review was performed on all consecutive prepectoral one-stage breast reconstructions using this technique at a single institution. Patient demographics, mastectomy and reconstruction characteristics, reconstructive outcomes, and cost of support materials were queried and analyzed. Eleven patients (21 breasts) underwent prepectoral immediate implant reconstruction with Vicryl and acellular dermal matrix anterior coverage. Average mastectomy weight was 775.8 g. Smooth, round cohesive implants were used in all cases and average implant size was 514.5 ml. Overall complication rates were low and included one minor infection (4.8 percent) and one case of minor mastectomy flap and partial nipple necrosis each (4.8 percent). Calculated cost savings of Vicryl and acellular dermal matrix anterior coverage was up to $3415 in unilateral and $6830 in bilateral cases. Prepectoral breast reconstruction using acellular dermal matrix inferiorly and Vicryl mesh superiorly is a safe technique that decreases material costs associated with support materials and allows the surgeon to precisely control the implant pocket and position.
