After Septoplasty Surgery Can the Nasal Splints Be Left in Permanently?

While it's not typical to leave nasal splints in the nose permanently, it sounds like something isn't quite right with your nose. A thorough examination with an otolaryngologist (Ear, Nose Throat) should help you figure out what exactly is going on.

It would be unlikely that splints have been left in for 25 years. At any rate it sounds like you are having a problem, you might want to have an Otolaryngologist look in your nose to see what is causing your complaints.

Hope this was helpful. 

No, the splints would eventually erode into the septal mucosa causing an infection and possible septal perforation.
