What is one way to keep the maximum number of fat cells alive during graft harvest?

• A. Using a small bore cannula
• B. Using a large bore cannula
• C. Using a sharp scalpel
• D. Using a laser incision

Answer: (B)

Using a large bore cannula during graft harvest is significant for maximizing the number of viable fat cells that can be obtained. This approach enhances the ability to extract a greater volume of adipose tissue while minimizing damage to the fat cells. The larger diameter of the cannula allows for more efficient removal of tissue, which can help to preserve the integrity of the fat cells. Smaller bore cannulas may restrict the flow and increase the trauma to the cells, leading to lower viability due to mechanical disruption. Overall, the technique of using a large bore cannula is critical because it reduces the shearing forces exerted on the adipocytes, thereby maintaining a higher proportion of live cells for transplantation. In clinical practice, maintaining fat cell viability is crucial for the success of procedures involving fat grafting, as the survival of the graft is dependent on the health of the harvested fat cells.
