A tracheotomy is a surgical procedure in which a cut or opening is made in the windpipe (trachea). The surgeon inserts a tube into the opening to bypass an obstruction, allow air to get to the lungs, or remove secretions. The term tracheostomy is sometimes used interchangeably with tracheotomy. Strictly speaking, however, tracheostomy usually refers to the opening itself while a tracheotomy is the actual operation.
Description
Emergency tracheotomy
There are two different procedures that are called tracheotomies. The first is done only in emergency situations and can be performed quite rapidly. The emergency room physician or surgeon makes a cut in a thin part of the voice box (larynx) called the cricothyroid membrane. A tube is inserted and connected to an oxygen bag. This emergency procedure is sometimes called a cricothyroidotomy.
Nonemergency tracheotomy
The second type of tracheotomy takes more time and is usually done in an operating room. The surgeon first makes a cut (incision) in the skin of the neck that lies over the trachea. This incision is in the lower part of the neck between the Adam's apple and top of the breastbone. The neck muscles are separated and the thyroid gland, which overlies the trachea, is usually cut down the middle. The surgeon identifies the rings of cartilage that make up the trachea and cuts into the tough walls. A metal or plastic tube, called a tracheotomy tube, is inserted through the opening. This tube acts like a windpipe and allows the person to breathe. Oxygen or a mechanical ventilator may be hooked up to the tube to bring oxygen to the lungs. A dressing is placed around the opening. Tape or stitches (sutures) are used to hold the tube in place.
After a nonemergency tracheotomy, the patient usually stays in the hospital for three to five days, unless there is a complicating condition. It takes about two weeks to recover fully from the surgery.

Definition
A tracheotomy is a surgical procedure that opens up the windpipe (trachea). It is performed in emergency situations, in the operating room, or at bedside of critically ill patients. The term tracheostomy is sometimes used interchangeably with tracheotomy. Strictly speaking, however, tracheostomy usually refers to the opening itself while a tracheotomy is the actual operation.
Purpose
A tracheotomy is performed if enough air is not getting to the lungs, if the person cannot breathe without help, or is having problems with mucus and other secretions getting into the windpipe because of difficulty swallowing. There are many reasons why air cannot get to the lungs. The windpipe may be blocked by a swelling; by a severe injury to the neck, nose, or mouth; by a large foreign object; by paralysis of the throat muscles; or by a tumor. The patient may be in a coma, or need a ventilator to pump air into the lungs for a long period of time.
Demographics
Emergency tracheotomies are performed as needed in any person requiring one.

Diagnosis/Preparation
Emergency Tracheotomy
In the emergency tracheotomy, there is no time to explain the procedure or the need for it to the patient. The patient is placed on his or her back with face upward (supine), with a rolled-up towel between the shoulders. This positioning of the patient makes it easier for the doctor to feel and see the structures in the throat. A local anesthetic is injected across the cricothyroid membrane.
Nonemergency Tracheotomy
In a nonemergency tracheotomy, there is time for the doctor to discuss the surgery with the patient, to explain what will happen and why it is needed. The patient
For a tracheotomy, an incision is made in the skin just above the sternal notch (A). Just below the thyroid, the membrane covering the trachea is divided (B), and the trachea itself is cut (C). A cross incision is made to enlarge the opening (D), and a tracheostomy tube may be put in place (E). (Illustration by GGS Inc.)
is then put under general anesthesia. The neck area and chest are then disinfected and surgical drapes are placed over the area, setting up a sterile surgical field.
Aftercare
Postoperative Care
A chest x ray is often taken, especially in children, to check whether the tube has become displaced or if complications have occurred. The doctor may prescribe antibiotics to reduce the risk of infection. If the patient can breathe without a ventilator, the room is humidified; otherwise, if the tracheotomy tube is to remain in place, the air entering the tube from a ventilator is humidified. During the hospital stay, the patient and his or her family members will learn how to care for the tracheotomy tube, including suctioning and clearing it. Secretions are removed by passing a smaller tube (catheter) into the tracheotomy tube.
It takes most patients several days to adjust to breathing through the tracheotomy tube. At first, it will be hard even to make sounds. If the tube allows some air to escape and pass over the vocal cords, then the patient may be able to speak by holding a finger over the tube. Special tracheostomy tubes are also available that facilitate speech.
The tube will be removed if the tracheotomy is temporary. Then the wound will heal quickly and only a small scar may remain. If the tracheotomy is permanent, the hole stays open and, if it is no longer needed, it will be surgically closed.
Home Care
After the patient is discharged, he or she will need help at home to manage the tracheotomy tube. Warm compresses can be used to relieve pain at the incision site. The patient is advised to keep the area dry. It is recommended that the patient wear a loose scarf over the opening when going outside. He or she should also avoid contact with water, food particles, and powdery substances that could enter the opening and cause serious breathing problems. The doctor may prescribe pain medication and antibiotics to minimize the risk of infections. If the tube is to be kept in place permanently, the patient can be referred to a speech therapist in order to learn to speak with the tube in place. The tracheotomy tube may be replaced four to 10 days after surgery.
Patients are encouraged to go about most of their normal activities once they leave the hospital. Vigorous activity is restricted for about six weeks. If the tracheotomy is permanent, further surgery may be needed to widen the opening, which narrows with time.
Risks
Immediate Risks
There are several short-term risks associated with tracheotomies. Severe bleeding is one possible complication. The voice box or esophagus may be damaged during surgery. Air may become trapped in the surrounding tissues or the lung may collapse. The tracheotomy tube can be blocked by blood clots, mucus, or the pressure of the airway walls. Blockages can be prevented by suctioning, humidifying the air, and selecting the appropriate tracheotomy tube. Serious infections are rare.
Long-Term Risks
Over time, other complications may develop following a tracheotomy. The windpipe itself may become damaged for a number of reasons, including pressure from the tube, infectious bacteria that forms scar tissue, or friction from a tube that moves too much. Sometimes the opening does not close on its own after the tube is removed. This risk is higher in tracheotomies with tubes remaining in place for 16 weeks or longer. In these cases, the wound is surgically closed. Increased secretions may occur in patients with tracheostomies, which require more frequent suctioning.
High-Risk Groups
The risks associated with tracheotomies are higher in the following groups of patients:
children, especially newborns and infants
smokers
alcoholics
obese adults
persons over 60
persons with chronic diseases or respiratory infections
persons taking muscle relaxants, sleeping medications, tranquilizers, or cortisone
Normal Results
Normal results include uncomplicated healing of the incision and successful maintenance of long-term tube placement.
Morbidity and Mortality Rates
The overall risk of death from a tracheotomy is less than 5%.
Alternatives
For most patients, there is no alternative to emergency tracheotomy. Some patients with pre-existing neuromuscular disease (such as ALS or muscular dystrophy) can be sucessfully managed with emergency noninvasive ventilation via a face mask, rather than with tracheotomy. Patients who receive nonemergency tracheotomy in preparation for mechanical ventilation may often be managed instead with noninvasive ventilation, with proper planning and education on the part of the patient, caregiver, and medical staff.

tracheotomy (trākēŏt'əmē), surgical incision into the trachea, or windpipe. The operation is performed when the windpipe has become blocked, e.g., by the presence of some foreign object or by swelling of the larynx. A curved or flexible tube is inserted into the trachea to facilitate breathing. In diseases such as pneumonia that cause the lungs to fill with fluids, this same incision may be used to drain the lungs. A tracheostomy is the surgical formation of a rounded opening into the trachea and differs from a tracheotomy in that the former procedure establishes a permanent opening.
Incision of the trachea through the skin and muscles of the neck for exploration, for removal of a foreign body, or for obtaining a biopsy specimen or removing a local lesion.
Tracheotomy and tracheostomy are surgical procedures on the neck to open a direct airway through an incision in the trachea (the windpipe). They are performed by paramedics, veterinarians, emergency physicians and surgeons. Both surgical and percutaneous techniques are now widely used.
While tracheostomy may have possibly been portrayed on ancient Egyptian tablets,[1] the first correct description of the tracheotomy operation for patients who are suffocating was described by Ibn Zuhr in the 12th century,[2] and the currently used surgical tracheostomy technique was described in 1909 by Dr. Chevalier Jackson of Pittsburgh, Pennsylvania.
Tracheotomy, from the Greekroottom- meaning "to cut," refers to the procedure of cutting into the trachea and is an emergency procedure.[3]
A tracheostomy, from the root stom- meaning "mouth," refers to the making of a semi-permanent or permanent opening, and to the opening itself.
Some sources offer different definitions of the above terms. Part of the ambiguity is due to the uncertainty of the intended permanence of the stoma at the time it is created.[4]
Uses of tracheotomy
The conditions in which a tracheotomy may be used are:
Chronic / elective setting - when there is need for long term mechanical ventilation and tracheal toilet, e.g. comatose patients, surgery to the head and neck.
In emergency settings, in the context of failed endotracheal intubation or where intubation is contraindicated, cricothyroidotomy or mini-tracheostomy may be performed in preference to a tracheostomy.
Placement of tracheal incision. An inferior based flap, or Björk flap, (through second and third tracheal rings) is commonly used. The flap is then sutured to the inferior skin margin. Alternatives include a vertical tracheal incision (pediatric) or excision of an ellipse of anterior tracheal wall.
Insert tracheostomy tube (with concomitant withdrawal of endotracheal tube), inflate cuff, secure with tape around neck or stay sutures.
Connect ventilator tubing.
It is also possible to make a simple vertical incision between tracheal rings (typically 2nd and 3rd) for the incision. Rear end flaps may produce more intratracheal granulation tissue at the site of the incisions, making it less favorable to some surgeons.
Percutaneous tracheotomy procedure
Curvilinear skin incision along relaxed skin tension lines between sternal notch and cricoid cartilage.
Midline blunt dissection down to the trachea (optional depending on technique).
Insertion of 14-gauge plastic cannula and needle with fluid filled syringe attached into trachea. Aspiration of air confirms correct placement of the tip in the trachea.
Removal of needle leaving cannula in place.
Insertion of soft tipped guide wire into trachea through cannula.
Removal of cannula leaving guide wire in place.
Tracheal dilatation is now undertaken - different techniques do this in different ways.
Ciaglia - the sequential insertion and removal of a series (usually 4-5) of increasing larger dilators over the wire into the trachea.
Griggs - insertion of a specially designed pair of guide-wire forceps along the wire into the trachea and then are opened to complete the dilation in one step.
Rhino - insertion of a single large tapered dilator over a plastic guidewire reinforcement.
Frova Percutwist - insertion of a specially designed screw of increasing diameter which rotates to create the dilatation.
Insert tracheostomy tube (with concomitant withdrawal of endotracheal tube), inflate cuff, secure with tape around neck or stay sutures.
Connect ventilator tubing.
Risks
During the procedure, there is a risk of damaging the recurrent laryngeal nerves. These nerves control the vocal cords. If one of the nerves is damaged a patient will probably have a problem with his/her voice; if both of the nerves are damaged, the patient will lose his/her speech. This risk of nerve damage is the reason emergency tracheotomies are performed higher up, in the larynx and why tracheostomies have to be done in hospital under anesthetic. Professor Stephen Hawking lost his speech due to a tracheostomy after contracting pneumonia.
