That spitting suture appears to be one of the conchal bowl setback sutures; it needs to be removed. It appears that the removal could/should be done extremely easily during a simple office visit. I am sorry that you were disappointed with your results. Typically, otoplasty surgery strives to accomplish multiple corrections to the ear, including: 1) creating an antihelical fold, 2) pulling the ear back (reducing the angle behind the ear), and 3) reducing (sometimes) the size or depth of the conchal bowl. I can't tell without seeing pre-op photos, and without seeing more angles of the post-op views, but, it appears that those 3 stated goals were probably accomplished fairly well. What you also have, which is unusual - is some rather "different" - looking rippling in the concha and antihelical fold. Although you don't like the rippling, (and I am sorry that you don't), most people making your acquaintance would probably not notice it, and almost no one (I would say) could find it at all offensive-looking. I write this partly because - I don't believe the pursuit of an attempt to smooth the rippling would go well nor be "worth it". I hope this is helpful.
