ابن زهر
In 1000, Abu al-Qasim al-Zahrawi (936–1013), an Arab who lived in Arabic Spain, published the 30-volume "Kitab al-Tasrif", the first illustrated work on surgery. He never performed a tracheotomy, but he did treat a slave girl who had cut her own throat in a suicide attempt. Al-Zahrawi (known to Europeans as "Albucasis") sewed up the wound and the girl recovered, thereby proving that an incision in the larynx could heal. Circa AD 1020, Avicenna (980–1037) described tracheal intubation in "The Canon of Medicine" in order to facilitate breathing. The first correct description of the tracheotomy operation for treatment of asphyxiation was described by Ibn Zuhr (1091–1161) in the 12th century. According to Mostafa Shehata, Ibn Zuhr (also known as Avenzoar) successfully practiced the tracheotomy procedure on a goat, justifying Galen's approval of the operation.
