What is a Tracheostomy? A tracheostomy (trach) is a surgical procedure in which a doctor creates an opening (stoma) in the front of your neck into your windpipe. This opening allows air to flow in and out of your lungs. A small curved, plastic tube (tracheostomy tube) is then placed into the stoma. This tube serves as a pathway to make breathing and the clearing of secretions easier, and as a way to keep the stoma open. Back to top.
