Fig. 2.

Absolute volume (a) and Relative volume (b) dynamics of HA implants during 2 weeks in 5 phantoms. The 2nd test is projected in dashed lines. There are 2 groups without HAS: one HA injection without HAS (the green line) and one HA injection with solely 6 ml saline (orange lines). The light blue line is the HA with HAS ratio 1:2 (3 ml HA with respectively 6 ml HAS). The red and grey lines are respectively the HA with HAS ratio of 1:1, and 1:1/2.
