How Effective is Incision-less Otoplasty? What Are the Average Costs? Where Could I Get It Done?

My best advice is to pick the surgeon and not the technique. Few surgeons use the incision-less technique as it is a "blind" technique though this may be effective in the right hands.  Make sure you look for long term results. Most otoplasties can be done with limited incisions (minimally invasive) behind the ears allowing for direct visualization and greater control in reshaping the ear cartilage until you have the right shape with the sutures used just to insure it remains in this shape during the healing period and also allowing for skin re-draping on the changed ear cartilage framework .

Ther are many different techniques for otoplasty.  All the ones I am familiar with involve the incision being placed behind the ear.  The scar heals almost imperceptibly and is completely hidden from view.  

There are many ways of treating ears that stick out a little bit. I prefer using a technique that involves placing an incision behind the ear to allow access to the area that needs to be treated. The scar is normally very well hidden and I find that it allows for great result durability.

For adults the procedure can be done in an office procedure room with local numbing medication. This saves you the cost of operating room and anesthesiologist fees. The procedure fee itself varies depending on what needs to be done exactly but typically ranges from $2500-4000 or so (for both ears).
