Microthane® versus traditional implants

Microthane® is the proprietary name for POLYTECH's micro-polyurethane foam covered implant shell. 

Microthane® is an inert material, it is the tissue that responds or interacts differently with Microthane®, compared to silicone surfaces. 

The composition of collagen in the microscopic structure of capsules varies greatly from that observed in the smooth and textured implants capsules.1 Microthane® polyurethane foam is effectively a 3D scaffold creating an active contact zone between the patient tissues and the Microthane® implant.2

After implantation, highly vascularized tissue grows into the 3D matrix.3,4,5 This stimulates the body’s immune response and promotes excellent tissue adherence.6,7


3D scaffolding for an active contact zone

Progressively, the Microthane® surface will fill with healthy and highly vascularized tissue, allowing the body’s immune system to be active at the very surface of the implant.2,3,4,7

Proven Safety Profile8

  • Greater tissue adherence to reduce implant rotation and malposition9
  • Very low risk of Capsular Contracture10,11,12
  • Radiation therapy patients have shown a decreased rate of Capsular Contracture** 10,11,12
  • Long-term Stability9
  • High level of Predictability9,11,12



B-Lite® Microthane® - An exceptional combination

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 implants cause less stress to the breast tissue and support tissue stability.15

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.

Reliable and rigorous clinical research


  • No serious complications needing explantation, no capsular fibrosis, implant rotation or rupture
  • Only 4 minor complications complication rate (1.97%) 

Prospective study
Level of Evidence: III
Nº of patients: 90 (152 breasts)
Median follow-up: 41 months 

Journal: DGPW

POMPEI et al. 10

  • 1,2% CC rate

Retrospective study
Level of Evidence: III
Nº of patients: 131 (255 breasts)
Median follow-up: avg. 110 mos
Statiscal relevance: significant; P < .05

POMPEI et al. 11

  • Lower cumulative incidence of CC following 2-stage breast reconstruction, even when radiotherapy is performed

Retrospective study
Level of Evidence: III

Median follow-up: avg. 103,3 mos 

Journal: Aesthetic Surgery Journal


  • Patient’s satisfaction was estimated on a scale from 1 to 5. At the end of the observation period, 90% of patients under constant control revealed to be either satisfied or extremely satisfied with the outcomes (levels of satisfaction that ranged from 4 to 5).

Retrospective case series

LORETI et al. 12

  • After mastectomy and one-stage Immediate Breast Reconstruction, the use of polyurethane covered implants is associated with a lower incidence of CC compared to textured implants. This advantage is amplified several folds for patients who necessitate post mastectomy radiation therapy.

Retrospective study
Level of Evidence: III
Nº of patients: 312
Median follow-up: avg. 2 – 3 yrs


COYETTE et al. 23

  • SAFE to use in prepectoral DTI
  • STABLE without additional mechanical support
  • Prior breast irradiation should not be considered as a contraindication to prepectoral PU device placement

SALGARELLO et al. 22

  • At the 12-months follow up, the mean Q-score for satisfaction with breast was 71.73 with maximum up to 88%.

Retrospective study

Journal: Clinical Breast Cancer

DE VITA et al. 24

  • VERY HIGH patient satisfaction for DTI breast reconstruction
  • Likehood of cost effectiveness compared to ADM27

Retrospective study

CAGLI et al. 25

  • The formation of less fibrotic capsule may reduce the risk of CC occurrence, particularly with Microthane® and MESMO® surfaces.

Microthane® - Proven for breast reconstruction

Microthane® is designed to REDUCE the most common complications in breast surgery, including in breast reconstruction. Reoperations are a significant cost driver in healthcare systems 16,17,18 and have an impact on patient satisfaction.19 A lower rate of capsular contracture (III & IV) reduces the risk of reoperation.

  • Lower complication rate (Risk of CC III & IV)
  • Lower reoperation rate
  • Potential reduction of healthcare costs
  • Higher patient satisfaction (Higher quality of life)


How do you get started with Microthane®?

If you are familiar with traditional implantation techniques, Microthane® implants require some adjustments to your normal routine. It can take a number of cases for you to become comfortable. 

Working with Dr. Mario Mendanha, we have developed an easy to follow guide to the Microthane® surgical technique.

The course is now available on the new POLYTECHconnect Academy. You can register to the Academy and then review the course.

What our experts say

“As a woman and as a plastic surgeon, I think there is no other option for long lasting results than Microthane® in most of my cases”.

Dr. Luísa Magalhães Ramos
Reconstructive and Aesthetic Plastic Surgeon
Consultório de Cirurgia Plástica LMR
Lisbon, Portugal


”I use now Microthane® for all indications in primary, as well as secondary cases.
are the key drivers for me to select the right implant.“

Mr. Patrick Mallucci
MBCHB, MD, FRCS (PLAST) Medical Director
London, United Kingdom


”B-Lite® implants are the most important innovation in the last decade of breast surgery. Combining the right surface with the correct indication makes the difference. The 30% less weight has a huge impact on my patients for their quality of life.
My patients love them.“

Prof. Dr. Moustapha Hamdi
Chairman at Plastic Surgery Department
Brussels University Hospital


”I believe B-Lite® in combination with Microthane® is the best implant a patient can get for reconstruction. The 50% less pressure that B-Lite® delivers plus the stability and control of Microthane® gives patients an unbelievable advantage.“

Prof. Roy de Vita
Chief of Plastic and Reconstructive Surgery Dept.
Regina Elena National Cancer Institute, Rome
