Pdf Summary

The review examines biologic matrices—primarily acellular dermal matrices (ADMs) from human, porcine, or bovine tissue—and synthetic meshes, which may be absorbable or permanent. These materials provide implant coverage and stabilization, support soft tissues, and may help prevent capsular contracture. They are used in implant-based reconstruction, revision surgery, selected primary augmentations, and, increasingly, mastopexy and breast reduction. Their use in breast surgery is widespread but off-label.<br /><br />In reconstruction, ADMs and meshes can help define implant position in direct-to-implant and expander-based procedures, including prepectoral techniques. In aesthetic surgery, they may address implant malposition, recurrent contracture, thin tissue coverage, contour irregularities, and recurrent breast droop. Material selection depends on patient and tissue characteristics, prior radiation, the procedure, desired duration of support, and cost.<br /><br />Evidence on outcomes is mixed. ADM studies report both comparable complication rates and increased infection or seroma in some settings; incomplete incorporation and noninfectious “red breast syndrome” are additional concerns. Synthetic meshes appear to have generally favorable safety profiles, with some analyses finding fewer infections and seromas than with ADMs. Both material types may reduce contracture or improve implant position, but comparative findings are inconsistent. Aesthetic results and patient satisfaction are often favorable, yet evidence for aesthetic procedures—especially mastopexy and reduction—is limited, heterogeneous, and based on relatively small studies or short follow-up.<br /><br />Synthetic meshes are generally less expensive than ADMs, although potential downstream costs and long-term cost-effectiveness remain uncertain. The authors conclude that both materials can be useful when matched to surgical goals and individual patient factors, but emphasize the need for larger, controlled, long-term studies and standardized outcome measures.
