212 Chapter 9 Addition of PRP speeds up recovery, but does not increase patient satisfaction Patient questionnaire reported recovery time, derived from the number of days returning to work/social activities with or without camouflaging agents, showed a significant faster recovery in the PRP+ group (Table 2). Mean number of days returning to work/Social activities with camouflaging agents was 9 days (μ=9,133 σ =3,701, p<0.01) in the PRP+ group and 15 days in the control group (μ=15,43 σ =4,949). Return to work/social actives without camouflaging agents supported this finding (PRP +: μ=14,87 σ =4,604 vs PRP -: μ=20.57 σ =6.61 p<0.05). Questions regarding noticeable differences in facial volume and skin quality after 2 and 4 weeks showed no differences (p > 0.05). Patient satisfaction, changes involume and skin quality, reported after 6months proved to be similar in both groups (data not presented). Overall satisfaction was reported as ‘moderate’. Positive skin changes were reported by several patients in both groups, contradicted by patients that did not notice any skin changes at all. Overall, the level of recommendation of the procedure to peers was negative for both groups, mainly as told by them because of higher expectations of the effect of the procedure. Table 2.
