Bioplastique at 6 Years: Clinical Outcome Studies

Abstract

Bioplastique is a biphasic polymer for the permanent augmentation of some soft tissues. It was developed in 1987, and clinical studies at this institution were begun in 1990. The combination of low molecular weight polyvinylpyrrolidone and solid polymer particles allows the implantation of permanent polymer spheres through a small needle under local anesthesia. In this study 127 cases are reviewed of consecutive patients who have received Bioplastique for scar revision, wrinkles, and augmentation for soft-tissue defects at 6 years after application. All patients who had not been in for follow-up recently were contacted by mail and questioned on the permanence of augmentation and migration of particles. About 30 percent of the patients were unreachable and had their charts reviewed for permanence and migration of particles. In eight of these cases, Bioplastique was removed because of overcorrection, two of them may have had infection. Bioplastique has gained wide use throughout the world and although some complications have been reported, in general, it functions quite well when used in selected cases.

Textured polydimethylsiloxane elastomers in the human larynx: Safety and efficiency of use

“…This has been shown in cosmetic surgery, where the PDMS elastomers are placed in fairly static areas of the body. 4 Our results also indicate that, in the human vocal fold, oscillating in the expiratory air flow even though paralyzed and therefore under mechanical stress, the PDMS bulk remains virtually unchanged. On the other hand, this permanent change is also irreversible.…”

Medialization framework surgery for voice improvement after endoscopic cordectomy

“…In fact, our correction attempts using collagen injections failed because the vocal cord structure no longer exists and thus the collagen no longer remains enclosed in Reinke's space but diffuses before host cells have had the opportunity to colonize it [27,29]. Furthermore, silicone [16], fat [34] and bioplastic [9] must be injected between the cartilage and the vocal cord. This is no longer possible after total or extended cordectomy.…”

Tissue augmentation using Bioplastique® as a treatment of leakage around a Provox® 2 voice prosthesis

“…It is commonly used for subdermal administration in the augmentation and restoration of soft tissue defects and contour de ciencies in the areas including the malar region, nasal bridge, the nasal tip, the chin and mandibular lining. 9 It is also used in urology for the treatment of vesicoureteral re ux and urinary stress incontinence. 1 0 In Laryngology Bioplastique® is used for vocal cord medialization.…”
