Can the rim of my ear be pinned back with an incisionless otoplasty?

I had an otoplasty 4.5 months ago. My doctor said he could further pin back the entire rim of my ear (on the left) with an incisionless technique to make it more symmetrical with my other ear (on the right). Do you believe an incisionless otoplasty will be effective? Addionally, I’ve read that an incisionless otoplasty relies on the sutures surviving, and if one of them ruptures years down the line that will compromise the result. Is that accurate? Thank you!
