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-wound care consisting of soaks and ointment application.

Design: Thirty-five patients with closed dressings compared retrospectively with 35 control subjects with open-wound care. In a prospective evaluation, 27 patients with closed dressings were then compared with 27 historical controls matched by age, sex, skin type, and treatment technique. Erythema, crusting, swelling, pain, pruritus, purpura, long-term complications, and dressing comfort were evaluated.

Setting: Referral-based academic practice.

Results: Prospectively, closed-dressing and open-wound care groups differed significantly in maximum erythema severity (1.8 vs 2.0 on a scale of 0-3; P =.03), noticeable erythema duration (15.4 vs 31.1 days; P =.04), and time until complete erythema resolution (41.8 vs 96.1 days; P =.02). Swelling resolution was more rapid in the dressing group (12.1 vs 29.5 days; P =.02). Crusting was limited to uncovered areas in the dressing group, and crusting duration was shorter (5.0 vs 9.1 days; P<.001). Pain was more likely to be reported prospectively, but severity was mild, in the closed-dressing group. Other short- and long-term complications did not differ significantly. Subjective patient attitudes toward the dressing were positive.

Conclusions: Occlusive silicone dressing application decreases immediate postoperative morbidity with significantly reduced severity and duration of erythema and decreased duration of swelling and crusting. Long-term results and complication rates remain unchanged.
