208 Chapter 9 no significant age difference between both groups. Whole blood platelet counts were within normal range for all patients (Table 1). Of all patients that completed the study, 13 received lipofilling with PRP (PRP+) and 12 lipofilling with saline (placebo, PRP- ). Average photographic results are presented in Fig 3. Mean patient age at time of operation was 52 years (±6.75, [38-63]), with no significant age difference between both groups. Whole blood platelet counts were within normal range for all patients (Table 1). Table 1. Study population characteristics. * students’ t-test Lipofilling with or without PRP does not significantly change overlying skin elasticity in this study Analyzed R7 parameter data (representing true elasticity) from both groups, showed no significant difference before intervention (Fig. 5). The PRP+ group did not differ significantly from the placebo group at any moment. Data correction for age, room temperature, humidity conditions and baseline (pre-operative) measurements resulted in similar findings. Analyzed R5 and R6 data showed comparable values in both groups, at every follow-up moment.
