Abstract

Background

The use of acellular dermal or synthetic matrices has improved the functional and cosmetic outcome of implant-based breast reconstruction [1–4]. The new materials provide a scaffold for patient tissue ingrowth and act comparable to an internal supportive bra to provide support for the implant and allow reconstruction of larger breast volumes, a more pronounced ptosis and control of the infra-mammary fold [1–4]. However, there are major concerns related to the higher complication rates associated with the use of matrices resulting in reconstructive failure, the lack of prospective studies and long-time follow-up [5–7].

Moreover, it still remains unclear as to which of the matrices currently flooding the market meet the reconstruction requirements best [8]. The ideal matrix should be ready to use (without prolonged washing procedures), moldable yet mechanically stable, should not cause allergic, immunologic or toxic reactions and should be rapidly integrated into the tissue.

Additionally, the costs of the matrix will become a major factor for most hospitals and insurance companies in the future [3].

Conclusion

A new long-term absorbable surgical matrix, TIGR Matrix mesh was used in a total of 29 patients undergoing a total of 37 mastectomies and immediate reconstruction. Although the follow-up was short the TIGR Matrix mesh fulfills many desired characteristics and requirements for a matrix for use in implant-based breast reconstruction and is a promising new alternative to acellular, dermal or other synthetic matrices currently available.
