Is otoplasty possible to reshape the helix of my ear? (Photo)

My ears are asymmetrical. As you can see in my attached photos the helix of one ear is completely rounded where as the other ear appears to be pulled back causing the helix to have a flatness to it. This makes it look much smaller than the rounded ear (although the rounded ear doesn't stick out abnormally far, so I'm reluctant to have this one pinned back). Is it possible to restructure the shape of the helix of this ear so that it matches my other ear?
