Direct-to-Implant Reconstruction with Microthane®

Clinical Evidence and Advantages

Direct-to-Implant (DTI) reconstruction using Microthane® - our polyurethane-covered implant surface - offers key advantages in single-stage breast reconstruction, particularly for prepectoral placement¹. The micro-polyurethane 3D Matrix supports fibroblast ingrowth and tissue adherence, enhancing implant stability and reducing seroma, malposition, and capsular contracture risk^3,5.

Microthane® implants are a good choice even in cases of radiation treatment, which is known to dramatically increase the risk of capsular contracture³. With capsular contracture rates that can go up to 50% with smooth implants, the capsular contracture rate for micro-polyurethane foam covered implants is as low as 0-3%.^4,5

Microthane® significantly reduces the risks commonly associated with breast reconstruction - particularly in challenging cases like postmastectomy radiation therapy (PMRT). 

Loreti et al. reported a 70% lower risk of severe capsular contracture (grade III & IV) in PMRT patients receiving polyurethane implants compared to textured ones ³.
Additionally, De Vita et al. reported 93% patient satisfaction in a large cohort undergoing prepectoral DTI with Microthane®, highlighting its long-term comfort and aesthetic reliability ⁶.

These benefits support the cost-effectiveness of Microthane® versus acellular dermal matrices (ADM) due to reduced complications and fewer reoperations. 

B-Lite® lightweight implants covered with Microthane® are designed to be stable and predictable. They weigh up to 30% less than traditional silicone implants while maintaining an equivalent size, form, and function. Lightweight implant applies similar pressure as a conventional implant of about half the volume⁷ and support tissue stability.⁸

Great adherence and less stress are two factors that allow you to have better control over implant stability and implant long-term surgical outcome. Regular users around the world confirm that they and their patients are post-operatively satisfied and confident.⁹
