TIGR matrix for implant-based breast reconstruction - a long-term resorbable mesh

Area of Science:

• Plastic Surgery
• Biomaterials
• Surgical Innovation

Background:

• Biological and synthetic meshes are established for implant-based breast reconstruction.
• Single-stage direct-to-implant breast reconstruction offers advantages over traditional two-stage methods.
• Limited long-term data exists for resorbable synthetic meshes in breast reconstruction.

Purpose of the Study:

• To evaluate the outcomes of TIGR Matrix, a long-term resorbable synthetic mesh, in breast reconstruction.
• To assess mesh-related complications and identify associated risk factors.
• To contribute data on the long-term efficacy of synthetic meshes in aesthetic and reconstructive breast surgery.

Main Methods:

• Retrospective observational study of 49 patients (60 breasts) undergoing breast reconstruction with TIGR Matrix.
• Follow-up period of mean 12 months.
• Analysis of operative methods and complication rates, including correlation with patient factors like obesity.

Main Results:

• A cumulative mesh complication rate of 5.4% was reported.
• One implant explantation occurred due to infection.
• Obesity was identified as a significant risk factor for mesh-related complications.

Conclusions:

• TIGR Matrix demonstrates acceptable complication rates in breast reconstruction, comparable to other synthetic meshes.
• Obesity is a significant predictor of mesh-related complications, warranting careful patient selection.
• This study supports the potential for increased use of cost-effective resorbable synthetic meshes in breast reconstruction.
