Why are aftercare instructions so different between doctors?

[bsmit]

I am 12 days post-op, and naturally, I began browsing the internet for guidance in the immediate post-op phase. I began noticing that post-op instructions vary widely between doctors. For example, my doctor instructed me two spray saline on the grafts every two hours for two weeks in order to prevent the grafts from drying out (which I plan on doing). However, I noticed that other doctors do not require saline application at all. I’m curious to hear if others were required to apply saline as part of their aftercare regime. Also, do you believe that saline can promote graft survival? I look forward to hearing from you guys! Thanks in advance!
