Why is Sushruta called 'the father of plastic Surgery'

Sushruta was one of the earliest surgeons in recorded history.He lived in the 6th century BC,nearly 150 years before Hippocrates, and left a book,the 'Sushruta Samhita' explaining his surgical methods.In his book ,Sushruta described how to pull teeth,how to fix broken bones,and how to fix blockages of the intestines.
    Sushruta was the first physician to advocate what is today known as the 'caesarean' surgery.He was also an expert in removing kidney stones,and locating and treating fractures.
    Sushruta was the first physician who mended a nose almost 26 centuries ago.The technique he used is not very difficult from what a plastics surgeons uses today.
