There is less fear and more desire for what is autologous. The areas where autologous fat can be extracted are generally the inner and outer thighs, buttocks, abdomen and upper limbs. The parts that can be filled with good results are: temporal, cheeks, lips, chest, buttocks, tear troughs and eye hollows after eye bag surgery, congenital and post-surgical upper eyelid hollows, forehead augmentation, apple muscle augmentation (zygomatic bone department) and facial hemifacial atrophy patients and nasolabial folds. The survival rate of the injected fat is a major concern for both the patient and the surgeon. The survival rate of injected fat is higher in patients with upper and lower eyelid depressions, and is associated with a higher absorption rate in all other areas. Therefore, fat grafting sometimes requires 2-3 injections. Of course, there is a correlation between the survival rate of the fat and the level of injection. Through fat injection, nasolabial folds can disappear, depressed areas can be improved, breasts can be enlarged, and fine wrinkles can disappear. At the same time, liposuction can have a body contouring effect. Candidates need fat injection must avoid menstruation, need to take a bath before the operation, do not massage after the operation (affecting the survival of the fat), suction and filler need to prevent infection after the operation, does not affect the work. For rhinoplasty, chin augmentation is still recommended to patients through the prosthesis to achieve, because the embodiment of such a bony three-dimensional structure is still better to use hard tissue.
