Abstract:
Three D surface technology is used to demonstrate to the patients the expected changes possible with a particular procedure.rnThis technology has allowed the patient and surgeon to both see the expected result at the same time on the same screen.rnThis will help the surgeon identify the patient’s expectations and be cautious about patients who have unrealistic expectations.rnThe Surgeon can also define the steps of surgery and plan it more accurately. The goal is to improve the patient’s satisfaction withrnthis technology and minimize the revision.The aim of this paper is to describe the author’s experience with 3DSI and 3DSM.rnMethod: The 3D images are normally taken with digital camera with adequate lightning and then stored in a computer andrnimages then manipulated using Software. The image can be captured with a camera or the surface can be scanned with a scannerrnbut the latter would require the subject to be motionless for a longer time. The author used the Vectra H1 camera for the facernand the Vectra XT for the body with the mirror image software for manipulation. A single camera is usually adequate (H1) butrnthe 3D camera system (Vectra XT) is more precise and will acquire better and larger images. Once the images are taken, theyrnare transferred to a computer where software stitches the images together. The problems of this system are the cost, limitedrnavailability and resolving the shiny of transparent areas and imaging hair. With the expansion of 3D printing, the cost hasrnsubstantially decreased and becoming more readily available for personal or central use. This is going to be helpful for patients’rneducation and archiving of pre-operative and post-operative results.The main limitation of the process is the cost associated withrnthe products and with the images capturing.rnResults & Discussions: Currently, 2D photography is used to document, analyze and plan surgical procedures in Plastic Surgery.rnThis tool does not represent 3 dimensional figures accurately. It lacks shaped and topographic depth. 3 D imaging measuresrnXY and its coordinates and uses a triangulation concept. It is better than MRI and CT Scans which do not reflect the surfacesrnand surface topography and also it is less expensive and less invasive to the patient. It overlays multiple images from differentrnplanes, over the same object to create a 3D image. The use of Magnetic Resonance Imaging (MRI) is more accurate and morernscientifically helpful in exact measurements however it uses screening tool that is not practical especially in cosmetic practicernas MRI scans are costly and are not readily accepted by the patients. Therefore, its uses are still not foreseen in the near future.rnConclusion: Three-Dimensional Surface Modeling (3DSM) is a useful tool in: 1. For the surgeon to understand the exactrnconcerns of the patients and to have more precise planning of the procedure. 2. For the patients to see the expected changes. 3.rnIt is important to emphasize that this is only digital morphing which may not reflect the actual outcome.

Keynote: Long lasting fillers
Time : 9:45
Biography:
Sahar Ghannam was graduated in 1983 from Alexandria University Egypt with a Master Degree of Dermatology, Venereology & Andrology in 1986. She receivedrna PhD in 1994 with a thesis on chronological aging, photo aging and ionizing radiation effects on the skin in 1995 a board examination was passed to successfullyrnachieve Doctorate Degree of Dermatology Venereology & Andrology. During that time she upscaled in the University positions from a teacher assistant until AssociaternProfessor in Alexandria University. Since that time, she has been interested in aging and anti-aging procedures. She is a Board Member of the International Societyrnof Dermatologic Surgery (ISDS) and the Executive Director of the International Peeling Society (IPS). She is the co-author of the Chemical Peel chapter in thern3rd edition of “Surgery of the Skin” published by Elsevier. He has published over 20 scientific papers. She is the Editorial Advisory Board of the Indian Journal ofrnDermatology and the Journal of Clinical and Aesthetic Dermatology. She travels a lot lecturing and teaching but also learning.
Abstract:
The field of facial aesthetic surgery is experiencing explosive growth in non invasive and minimally invasive procedures.rnBiosynthetic fillers such as Ca hydroxy apatite, Polycaprolactone and poly L Lactic acid are biodegradable fillers andrnconsidered to be long lasting fillers. Poly L lactic acid was the first one to be used in aesthetic surgery it is a polymer that providesrnsoft tissues augmentation through stimulation of an inflammatory tissue response with subsequent collagen deposition. Carnhydroxy apatite and Polycaprolactone each consists of a gel carrier and the Ca hydroxy apatite spheres and Polycaprolactonernspheres respectively , that once injected in the subcutaneous space, the gel is slowly absorbed, what remains is a matrix ofrnmaterial which will take the characteristics of the cell that repopulate. When injected into the tissues space, fibroblast producesrncollagen. The author’s clinical experience with these three long lasting fillers will be presented.
