Laser resurfacing of silicone-injected skin: the "silicone flash" revisited.

چکیده
OBJECTIVE To determine whether prior silicone injection increases the risks associated with carbon dioxide laser resurfacing. DESIGN Laboratory determination of the effect of laser energy on liquid silicone; histologic evaluation of silicone-injected skin after lasing; and histologic demonstration of silicone deposits in all layers of dermis years after injection of silicone as filler fluid. SETTING Tertiary care medical center. PATIENT-RELATED DATA: Histologic examination of freshly excised skin injected with microdroplets of liquid silicone and subjected to application of carbon dioxide laser energy; histologic examination of skin excised years after silicone injection. INTERVENTIONS High-speed clinical photographic imaging of the effect of laser energy on silicone fluid; histologic examination of hematoxylin-eosin-stained sections of skin injected with liquid silicone and subsequently lased. MAIN OUTCOME MEASURES Response of liquid silicone to application of laser energy; effect of this response on surrounding normal skin. RESULTS Exposure of microdroplets of liquid silicone to carbon dioxide laser energy produced flaring with frank flame. Flaring of dermal silicone caused collateral skin damage. CONCLUSIONS Prior injection with liquid silicone is a relative contraindication to cutaneous resurfacing with the carbon dioxide laser. Surgical excision of silicone-injected skin may be preferable for many patients. A strenuous needs assessment should be done, alternatives for skin rejuvenation considered, and comprehensive informed consent obtained from the patient before embarking on laser resurfacing of silicone-injected skin.

Evaluation of a silicone occlusive dressing after laser skin resurfacing.
BACKGROUND Closed dressings are thought to promote postoperative wound healing after laser skin resurfacing; however, quantitative data are lacking. OBJECTIVE To compare postoperative healing after combination carbon dioxide and erbium:YAG full-face laser skin resurfacing in patients who were treated with a silicone occlusive dressing (Silon-TSR; Bio Med Sciences, Inc, Bethlehem, Pa) vs open-...

Erbium:YAG Laser resurfacing of periorbital skin: Report of 7 cases
Nowadays, Erbium: YAG laser resurfacing of periorbital skin has become a very popular method of wrinkle reduction. Seven patients with Fitzpatrick skin phototypes of II to V were treated with a 2940 nm Erbium: YAG laser system for resurfacing of periorbital wrinkles. Photographic evalution performed before and after treatment. Patients were visited at 1,2,3,5,7,14,30 and 60 days after laser res...
متن کاملSurface Modification of Silicone Rubber Membrane by Microwave Discharge to Improve Biocompatibility
Wetability of biocompatible polymers can be improved by plasma surface modification. The purpose of this study was to surface modify an experimental poly (dimethylsiloxane) rubber (PDMS) material in order to improve its wetability and biocompatibility. Surface properties of the PDMS were characterized using contact angles measurement for wetability analysis. Samples of experimental silico...
