If one has had their voice box removed, they will have a permanent stoma to breathe through. They need this because the connection between their windpipe and mouth has gone. The stoma is called a tracheostomy or laryngectomy stoma. A breathing stoma is a hole (opening) made in the skin in front of the neck to allow you to breathe. The opening is at the base of their neck. Through this hole, air enters and leaves their windpipe (trachea) and lungs. One may need a stoma if their mouth or oropharyngeal cancer is blocking their throat and it is too big to completely remove, or if they have swelling in and around their voice box after radiotherapy. These situations are most likely to happen with very large tumours of the tongue and oropharynx.
I would say the chemicals that are inside of it, are poison and cause bad damage to your throat. The doctor probably has to cut the infected area of your throat out. Which is very gross. -Like My Post If You Agree!
These people have had cancer of the larynx and have had to have life saving surgery. The larynx and often parts of the esophagus and tongue have been removed. These folks must breath through a stoma (the hole) and often have to eat through a tube. This is most often caused by smoking.
