P147 : How to inject filler safely and effectively: new paradigm inspired from old
( Kyukwang Whang ),( Eunsun Choi ) 대한피부과학회 2014 대한피부과학회 학술발표대회집 Vol.66 No.2
Background: Filler injections almost always give the horror of vascular occlusion, skin necrosis, and inadequate injection etc. Objectives: To prevent the complication and inappropriate injection, ‘bead ice cream theory’ is suggested here, which is inspired from ‘microdroplet technique’ historically old theory, and is easy for a even beginner. Various size and shape of beads can be injected with various spaces between beads for adequate shaping. Methods: Various size and shape of beads is injected with various spaces between beads for adequate shaping. Recommended method is that bolus or bulky amount of injection should be avoided. Linear thread or bolus shape can be moved, but small droplet is fixed to surrounding tissue, not to be easily moved.(Cell Method) It is more beneficial and safe method especially for non HA filler. Results: Beads of filler (Cell Method) injected to vertical and horizontal direction coincidentally, and multi layer injection that is in the upper dermal, subcutaneous, supra-muscular and supra-periosteal layer was effective for 3 dimentional contouring. Conclusion: These paradigms would be helpful to inject filler safely and effectively, and are introduced with diagram and clinical cases.

Study about the result of serial excision was not many, and not evaluated in detail. Objectives: For the statistical analysis of serial excision of congenital melanocytic nevus, and how to do efficiently and to reduce stages and the length of scar. Methods: 33 patients during 8 years are included among cases of serial excision of congenital melanocytic nevus patients. Results: Sex ratio is 7 male, and 26 female. Locations are 11 face, 6 arm, 11 lower extremity, and 5 body area. Mean of surgical stages was 2.24. Interval between surgery was 10.575 month. Mean size of CMN was 19.67cm2. 18 Er:YAG, 13 Nd:YAG, 27 pulsed dye laser and 9 CO2 fractional lasers were added for improving final results and scars. S shaped excision was preferred than straight design to reduce stages and scars. Conclusion: Serial(staged) excision was powerful option with higher satisfaction especially in medium sized and hairy congenital melanocytic nevus. S shape designed excision enabled to make less operation stage, showed better shape and result than the straight design. It had limitation around vital organ like eye, nose and mouth, and then combination treatment like Er:YAG ablation and Nd:YAG was necessary. During some of excision, change of axis of defect after underming was helpful to reduce length and scar.
