Can I have an otoplasty revision after 4 months?

I had an otoplasty surgery 4 months ago to create the anti helical fold. At first, I was happy with the results but then the upper part of the ears started sticking out. when I feel the back of my ear, it seems that the surgeon only placed stitches on the middle third of the ear. Is it possible to have a revision after 4 months just to tuck the upper part of the ear? Is this a minor procedure? What is recovery like? Will I have to wear bulky head dressing again?
