Titanium implant for nose, can it be well tolerated?

There is absolutely no reason to use titanium a foreign substance in the nose. The nasal valve can be opened as I have done for 35 years using cartilage which will last your lifetime and have no foreign body reaction. See a very experienced rhinoplasty surgeon and avoid titanium.

 We have never used titanium implants for the nose, and have never heard of them. There are many issues that can cause nasal obstruction such as a valve collapse, vestibular stenosis, turbinate hypertrophy, chronic sinusitis, allergies, and a deviated nasal septum. Each one of these is treated differently with either medications or surgery. Treatment for valve collapse usually consists of spreader grafts composed of the patient's own cartilage placed underneath a concave and weak upper lateral cartilage. For more information and many examples, please see the link and the video about spreader grafts below

Dear Sophitia, Nasal valve issues have been handled through the years very successfully with natural cartilage from the patient.  I would never suggest titanium and the risk of a foreign body reaction possibly leading to multiple complications. Keep it simple, easy and natural. Best regards, Michael V. Elam, M.D.

There's a very good reason other surgeons don't do that. It's a terrible and very risky idea.
