Removal of Gortex Implant, Improving Tip Definition, and Narrowing Nasal Base
Your tip definition can be improved and your nasal base narrowed to improve tip refinement. If the Gortex implant is remove because you're concerned about future movement,extrusion, or infection I suggest you consider placement with a diced cartilage/fascia graft to maintain good projection and definition of the bridge. The cartilage can be taken fro the septum or ears.This would avoid the need for a chest incision to harvest rib cartilage
Rhinoplasty revisions often require removal of Gortex grafts and replacement with costal (rib) cartilage grafts. This is done because Gortex will ultimately get loose, infected, and extrude. Good news is that rib grafts are now available as cadaveric (organ donor) grafts so it won't require harvesting your own rib cartilage. A consultation is necessary to provide you details of your surgery.
You do have slight cant of the dorsum from right to left when considering your nose from superior to inferior (top to bottom). If this is and issue for you consider removal or an attempt at repositioning. If removed something should be replaced. Rib cartilage in some form would be the best replacement. However, and this is a big however, there is the possibility that the replacement process may not make your dorsum straighter. So if the only thing that bothers you now is tip and alar base you might strongly consider leaving the gortex in place.
