Changes in Implant Thickness after Rhinoplasty Using Surgiform [PDF]

open access: yesArchives of Aesthetic Plastic Surgery, 2018
Background Gore-Tex implants started out as a product with the distinct advantage of producing a natural nose shape, but using Gore-Tex, it is difficult to predict the height of the nose after rhinoplasty because Gore-Tex contracts over time, making the ...
