Can sleeping on your stomach (with nose on pillow) do damage to results of Septorhinoplasty?

I am considering having a septoplasty/turbinate reduction combined with rhinoplasty. (I understand that part of the procedure will involve spreader grafts). I sleep on my stomach and my face (and nose) often get buried in the pillow. Can pressure on face/nose effect the results of the surgery? Surgeon tells me it would be too uncomfortable for me to do this after surgery anyway, but I'm wondering about longer term after healing -- i.e. damage to spreader grafts or re-deviation of septum)?
