I had septorhinoplasty/turbinate reduction 3 wks ago. I now sleep on my back; can I wear an eye mask to block ambient light?

I typically advise my patients to not place anything heavy on or over the nose for the first month after rhinoplasty. A cloth eye mask is typically lightweight and should not affect the rhinoplasty result. However, I would clarify this with your rhinoplasty surgeon in the event that they think otherwise and may advise against it.
