tracheostomy or tracheotomy
Term: tracheostomy or tracheotomy
Origin: ?nc Greek Anc Greek ???????/tracheia(= feminine gender of ??????/trachys=rough) > verb ???????/tarazo(=ruffle) + ?????/stoma(=mouth, orifice) à tracheostomy
or ????/tomi(=incision) à tracheotomy
Coined : Tracheostomy procedure existed right from the Rig Vedas. Later in the 8th cen BC Homer referred to relief afforded a choking person when trachea was opened. Hippocrates used tracheostomy in treatment of quinsy. Mention of tracheostomy could be found in the intervening Roman and Arabic literature but the technique was forgotten for n early 10000 years (Darc Agers). The tracheostomy was returned back in 18th and 19th cen during sporadic diphtheria epidemics in Napoli. Tracheotomy was coined in 1718 by German surgeon Lorenz Heister (1683-1758). Thracheostomy originally meant a permanent opening to be distinguished from the temporary nature of tracheotomy but today the terms are used interchangaeably to an y artificial aitrway created in trachea.
Definition:
A surgical procedure, consists of making an opening in the front of the trachea (windpipe). A tracheostomy is performed not because of a specific disease but because an indication is present as a result of a disease.
