Professional singer 8 weeks post septoplasty and turbinoplasty ... dry/cold nose and throat, nasal voice... is this normal?

I had septoplasty and bilateral turbinate reduction 8 weeks ago. When I breathe, the air feels very cold and dry (even inside a warm room) and immediately I feel air on my throat and to my lungs (cold,dry). I’ve been doing rinses, using humidifier and keeping nostrils moistened but I’m worried that my turbinates are not functioning properly. Also my voice is sounding nasal since the surgery even though it seems the swelling has subsided. Are these symptoms likely to balance out with more time?
