Edit Are there differences in fat transfer procedures?

<p><strong><em>In</em><em> my opinion, for the best survival of the fat, the following are some principles that might help:</em></strong></p> <ol> <li><strong>Use liposuction methods that cause the least trauma to the extracted fat cells:</strong> Laser-assisted liposuction and ultrasound-assisted liposuction methods might be too traumatic for the fat cells. Pure Tumescent Liposuction in my opinion causes the least trauma to the fat cells. Using low suction power will also cause less damage to the fat cells.</li> <li><strong>Avoid overprocessing the fat:</strong> Centrifugation with a high setting will kill the fat cells <span style="font-size: 8pt;">(5)</span>.</li> <li><strong>Transfer the fat as soon as possible:</strong> Avoid doing unnecessary large liposuction procedures if the main purpose is for fat transfer. The longer the fat is out of the body the more likely it will not survive. </li> <li><strong>Inject the fat in multiple layers (into fat and muscles) and in tunnels:</strong> Injecting the fat in one area and creating a pool of fat will make it harder for the fat cells to establish a blood supply and can cause fat necrosis (cell death) and fat cysts. </li> <li><strong>Advise the patient to avoid putting pressure on the recipient areas for about 3 weeks:</strong> High pressure might kill the fat cells. Avoid tight brassieres after fat transfer to the breasts and avoid sitting down after fat transfer to the buttocks. </li> </ol> <p><strong>Summary</strong></p> <p><em>In my opinion fat transfer or fat grafting is a safe and effective way to create a large volume of fat in areas that need it. However, more studies are needed to establish the best practice to get the best results for the patients.</em></p> <p>^{<em><strong>References: <br /></strong>1. Asilian A, Siadat AH, Iraji R.
