Using a curved barbell (or other jewelry), the tragus may be pierced vertically. This piercing was first popularized by piercer Luis Garcia. Many piercings that appear to be a vertical tragus piercing are actually surface piercings located immediately in front of the tragus. These can be done with a curved barbell as well, but are prone to rejection. The chance of rejection can be reduced by using surface bars, as well as having the piercing done by an experienced piercer. Even under optimal conditions though, they can still reject.
