To be able to answer your question, I have to know when your tragus got infected and when you had it lanced.
Please consult with your ENT surgeon to assess whether the narrowing also involve the external ear canal, if not, then a simple conchalplasty will solve the problem pretty easily, but if the external ear canal is also involved, then canaloplasty together with conchalplasty may be needed.
I agree with you that your photo does appear to show a narrow ear canal on one side and prominent ears on both sides. The narrow ear canal can be treated but does require surgery to remove cartilage and possibly some scar tissue/ fibrosis. The main risk of the procedure is the area narrowing again after surgery and your chosen surgeon should discuss this possibility with you. I do recommend in your case that you see a Facial Plastic Surgeon who has training in both facial plastic surgery and all aspects of surgery on the outer, middle and inner ear.

but you really need to see a local plastic surgeon to be evaluated and to listen to your history of how this all happened and determine if your ears are a result of your piercing or something that you simply had all your life.
