Rhinoplasty Through the Gums, is It Safe?

No advantage doing Rhinoplasty thru gums. Choose a surgeon who does natural noses you like and forget trying to figure out unusual approaches. 

 Rhinoplasty is performed by either closed or open techniques through the nose,not through an intra-oral approach. Closed  rhinoplasty techniques  involve incisions placed on the inside of the nose, which can include a tip-plasty,  osteotomies, placement of spreader grafts etc. Open rhinoplasty involves the incision across the columella.

There are certain maneuvers that are performed through an incision under the upper lip but this relatively uncommon. Tip modifications are performed either through an external or an endonasal (inside the nostril) approach. I am not aware of any approach to the tip via the area under the upper lip. The exposure would be very poor and ensuring any sort of symmetry would be a real challenge through this approach. This approach can be helpful for removing soft tissue or muscle and also for placing pre-maxillary grafts, but not tip work, in my experience. I hope this information is helpful.
