Why is fat graft placed after parotid resection?

The placement of fat grafts following parotid resection primarily serves to enhance cosmetic outcomes. This procedure often results in tissue deficits or irregularities in the contour of the face due to the surgical removal of the parotid gland, which is situated beneath the skin. By utilizing fat grafting, surgeons can fill in these spaces and restore a more natural appearance to the region, thereby improving overall aesthetics.

Fat grafting can also provide beneficial properties, such as promoting tissue healing and providing a buffer around delicate structures; however, these effects are not the primary aim of the graft in this context. While some of the other options mention improving gland function, reducing the risk of infection, or supporting nerve regeneration, these are generally not seen as the main reasons for placing fat grafts after parotid resection. The focus remains largely on achieving satisfactory cosmetic results following surgery.
