Investigating the use of tie-over dressing after skin grafting

Abstract

Tie-over bolster dressing after skin grafting can prolong operative time, and cause hematoma and seroma formation because of uneven pressure application. To describe the possibility of discontinuing the use of tie-over dressing, we carried out a retrospective comparative study of patients who underwent skin grafting at an institution between January 2009 and December 2014. We investigated and compared the take rate, healing period, wound infection rate and hematoma formation rate for the tie-over dressing group and the non-tie-over dressing group. Among 266 patients, 148 and 118 patients were included in the tie-over dressing group and non-tie-over dressing group, respectively. There were no significant differences between the take rate, healing period, wound infection rate and hematoma formation rate for the two groups. Multivariate analysis showed that the complete graft take rate was not significantly influenced by tie-over dressing, age, sex, graft site, graft procedure and skin graft diameter. Although the use of tie-over dressing might remain necessary on sites with a free margin, including the eyelids, lips or nostrils, because of the difficulty in using tape fixation, the present study showed that alternative dressing with polyurethane foam is also useful in most cases of skin grafting.
