 However, Aretaeus warned against the performance of tracheotomy because he believed that incisions made into the tracheal cartilage were prone to secondary wound infections and therefore would not heal.He wrote that "The lips of the wound do not coalesce, for they are both cartilaginous and not of a nature to unite".Antyllus, another Greek surgeon who lived in Rome in the 2nd century AD, was reported to have performed tracheotomy when treating oral diseases.
