title: The deposition of talc in patients with silicone gel-filled breast implants.
abstract: This study was initiated to understand why talc was found in the entrance wounds and pericapsular scars of patients with silicone breast implants. Twenty-five surgical gloves made between 1977 and 1992 by a major glove manufacturer were evaluated with infrared spectroscopy. Seven gloves manufactured before early 1983 contained talc. Later manufactured gloves contained calcium carbonate instead of talc. Talc-containing gloves were submitted to independent laboratories for scanning electron microscopic examination and x-ray microanalysis to obtain finer detail. Remnants of the mold-release agent talc were found in the matrix of the patient-contact side of the glove. Wetting studies showed that silicone oil (gel bleed) immediately wet the surface of rubber glove. After donning, silicone oil was massaged between the thumb and index finger of each washed, talc-containing glove for 1 minute and then daubed from the glove to a microscopic slide. The slide was viewed with polarized light microscopy for the presence of talc crystals. Transfer of talc occurred using silicone oil, but not saline, in each talc-containing glove. Three factors were likely involved in the greater talc deposition that occurred with patients undergoing silicone gel-filled breast implantation than in patients undergoing other surgical procedures. (1) The wetting of the gloves with silicone gel bleed from implants loosened the talc in the glove matrix. (2) Hand-intensive surgical use freed the talc from the gloves. (3) Loose talc adhered to the silicone elastomer of the breast implants and was deposited with implant placement.
