Summary
<p>Non-surgical aesthetic applications have become increasingly popular in recent years. Detailed knowledge of anatomy is much more important than the techniques and materials used for the effectiveness of the treatment and the prevention and management of complications. In this study, the location of the inferior orbicularis retaining ligament (ORL) and relations to zygomatic retaining ligament (ZRL) and infraorbital foramen (IOF), which are important limiting structures especially for infraorbital and cheek filler applications. Orbito-malar regions of fifty sides of 15 male/10 female cadavers will be dissected (by now 20 sides’ dissections were accomplished) under 2.5x magnifier. Inferior part of the orbicularis oculi muscle (orbital part) and levator labii superior muscle were elevated to show inferior part of the orbicularis retaining ligament and the infraorbital foramen. The distances between the inferior orbital rim and the ORL (A) and the distance between ORL and IOF (B) were measured on the vertical axis passing through the IOF were measured. Distance to IOF from the intersection point of the ORL and the zygomatic cutaneous fibres of ZRL (C) was measured transversely. The right angle distance to the lower orbital rim of the ORL-ZRL intersection point (D) was also measured. With limited data obtained to date from 20 sides the mean values in milimeters are, A: 2.92±0.74 (min:1.35 max:4.11); B: 7.78±1.2 (min:6.37 max:9.24); C: 10.70±1.94 (min:7,72 max:13,35) and D: 9,96±1,14 (min:7,80 max:12,29).
