		+	It seems that this article can permit applications on the medical domain.
		+
		+	The application introduced in this article is to propose an efficient model able to simulate the final rendering of fat filling surgery, taking into account the facial anatomy of the considered patient.
		+
		+	It is a pretty specific application, and it is hard to imagine other possible ways to use this simulation model.

	The main contribution of this article is a model created by the combination of two well known models. Those are the fluid model, usefull to predict the behaviour of the fat beneath the skin, and the deformable solid model, here to try to predict the skin deformation during and after the surgery.

 This article has the objective to propose an efficient way to simulate the result of a fat filling facial surgery. The final aim is to get some datas, sampled over a post-operative patient, and to compare the final rendering of the simulation with the real patient one.

 The fat-filling method is kinda different compared with all the plastic surgeries that we hear about every day. Those surgeries, like the breast augmentation or other facial modifications, often use implants, and it is easy to find works ans documentations about them.
-The main aim of this research is to propose an efficient model, able to simulate the final rendering of that kind of surgery and the problems that could be encountered. In fact, this model takes into account specific information about the patient, particularly his anatomy (ligaments, nerves and blood vessels), which can prove to be obstacles for the injected fat.

-With those specific datas, and relying on both fluid and deformable solid models, searcher of the INRIA lab were able to make their own model. Its aim is to calculate the error which could occur during the projection of the fat, meaning that input fluxes have theoretically to be equal to output ones.

 The first was to simulate a fluid injection between two layers, one was a deformable solid, the other a rigid solid. The conclusion of this test was that the model was coherent with fluid general behavior.
-The second was to simulate the surgery with real patient datas acquired by laser scan of his face. the aim here was to compare simulation result with the result obtained after a real fat-filling surgery. Finally, the deformations were similar, and that permitted to say that this model was realisitic, even if there was some differences between the simulation and the surgery outcome.

-This article deals with specific '''reconstructive facial surgery''' method, called fat-filling. The main purpose of this method is to inject some fat between different layers of tissus, which compose the skin and the muscles of the face, in order to reinflate the face and to fill hemifacial deformations which can be caused by diseases or accidents.
