Perforated septum after a revision rhinoplasty - can a septoplasty help fix this?

Septal perforation repair should be considered if:you're suffering from whistling noisenosebleeds attributable to thissignificant airflow disruption resulting in crusting throughout the perforation
Perforation repair is quite challenging, so see an experienced nasal surgeon if you meet one, or more, of the above criteria. It's quite different from a septoplasty in terms of approach and techniques.

If the problem continues you
Might consider a septal repair. In the meantime use lots of saline nasal spray. Sometime the whistling can be corrected by actually making the hole larger if all else fails.
