What are the risks of closed rhinoplasty using the "delivery" approach?

As long as you have found an experienced rhinoplasty surgeon that performs frequent rhinoplasty via the delivery approach then there shouldn't be any increased risk. This is a widely accepted approach for tip modification and enables your surgeon to create more changes in your nasal tip than a standard non-delivery closed approach.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

There are no increased risks if you are doing closed rhinoplasty several times a week and can do virtually anything through this approach.  Find a board certified plastic surgeon who performs hundreds
of rhinoplasties and rhinoplasty revisions each year. Then look at the
plastic surgeon's website before and after photo galleries to get a
sense of who can deliver the results. Kenneth Hughes, MD Los Angeles, CA

Closed rhinoplasty is less invasive than open rhinoplasty, and patients heal much faster with less swelling.  All of the incisions are placed inside the nose, so  there is not a visible scar on the columella. The delivery approach does not distort the cartilages since they're only exposed through marginal incision just like an open rhinoplasty. For many examples of closed rhinoplasty please see  the link  and the video below  to our closed rhinoplasty photo gallery.

some of the best most experienced rhinoplastic surgeons do noses this way -- it avoids and external scar which can be deforming. I love closed rhinoplasties.

There are no problems performing an alarplasty with a closed rhinoplasty. I have been doing it for 22 years. It will not distort or distroy the lower lateral cartilage AND there is no external scar.Best wishes
