Composite grafts are occasionally used in rhinoplasty, particularly in revisions. Nostril asymmetry in revision surgery is commonly due to post surgical alar retraction (scar tissue forming inside the nose). In order to correct this, you MUST both bring the nostril down with strong cartilage grafts, and also replace the skin inside the nose with a composite graft.
These grafts are harvested from the front of the ear, deep inside the bowl. Once healed, the scar is imperceivable. This does not change the shape, color, size, or function of the ear.
Typical appearance of the scar at 6 months. It is imperceivable by 4-6 weeks on average
