Can rhinoplasty affect ones singing voice?

The answer is yes, possibly.  If one's airway is changed, it can affect the vocal resonance for singers.  With that being said, usually the change is minor and is often for the better as it can improve a "nasally" sounding voice.  If you are considering a rhinoplasty, you should seek consultation with a facial plastic surgeon with expertise in managing the nasal airway.  Best of luck.

There are two main issues with having a rhinoplasty and its effect on the singer's voice. First, some physicians prefer to have their patients under general anesthesia, so a breathing tube must be inserted between the vocal cords. While this is usually an innocuous procedure, in theory, the vocal cords can be injured. This is something we discuss with singers,  although permanent injury to the vocal cords is a rare occurrence.The second issue is vocal resonance. I have had patients notice a change in their vocal resonance after sinus surgery, but most do not complain very much about changes in resonance after septoplasty. A purely cosmetic surgery will likely not produce any changes in vocal resonance, but septoplasty may cause some subtle changes.I would have a professional singer think very seriously about septorhinoplasty surgery (notice that Barbra Streisand never had her nose fixed..but Michael Jackson had many, many surgeries on his nose, which didn't seem to affect his singing.)

Geisha2264,in over 25 years of specializing in facial plastic surgery I have never had
a patient complain of this problem but anecdotally I've heard from other
physicians of a rare patient where this has been a concern. Septoplasty would
be my major concern. Hard to imagine a pure rhinoplasty having this issue but
I've learned over time to never say never. Should you be a professional take
this into consideration. Good
luck!
