Advantages 
• Cosmetic results are generally pleasing. Skin transferred from the abdomen to the chest wall is
  usually a good match in color and texture.
• A prosthesis is usually not required. 
• A "tummy tuck" follows the transfer of skin and fat from the lower abdomen. 

Disadvantages 
• Possible weakness or hernia of the abdominal wall.
• Additional scars across the upper chest and lower abdomen.
• Involves a major, lengthy surgical procedure under general anesthesia. 
• A plastic surgeon with microsurgery skills is required for the free flap technique. 
• There may be a higher risk of complications.
