    AbstractScientific controversy concerning silicone and its biocompatibility has been ongoing for the last 10 years. This study on textured and smooth silicone breast implant shells using fourier transformation infrared spectroscopy associated with attenuated total reflectance cells aimed to identify eventual chemical modifications of silicone induced by texturization. The surfaces of 8 new implants produced by 2 well-known manufactures have been taken into consideration. A sample 1 cm2 has been harvested from the anterior and posterior sides of textured and smooth shells. Infrared spectra were then recorded, evaluated, and compared with the reference spectrum of pure silicone. Potentially reactive groups, known as silanols, were identified, in all shells, intensity increasing in textured implants (P < 0.05), whereas no silanols were detected in the spectrum of pure silicone. These results suggest that polar groups, present in manipulated silicone might influence capsula formation.
