Association between cutaneous occlusive vascular disease, cigarette smoking, and skin slough after rhytidectomy.

This prospective study attempted to determine if nonreversible occlusive vascular changes in the skin contribute to skin slough after rhytidectomy. The dermal microvasculature from 83 consecutive rhytidectomies was evaluated for intimal proliferation and/or hyalin sclerosis. Occlusive vascular disease increased progressively with age in all patients, but smokers and ex-smokers had significantly greater involvement than nonsmokers at any given age (p = 0.03). Severe occlusive vascular disease and skin slough were associated (p = 0.02), and there was a strong trend toward an association between active smoking and skin slough (p = 0.06). Among smokers, there was a significant relationship between skin slough and failure to abstain from smoking postoperatively (p = 0.006). We conclude that with aging, nonreversible occlusive changes develop in the dermal microvasculature. These changes appear to be accelerated by cigarette smoking. Our data, however, show that these nonreversible occlusive vascular changes by themselves do not completely account for the occurrence of skin slough after rhytidectomy.
