Tracheostomy is an operative procedure that creates a surgical airway in the cervical trachea. It is most often performed in patients who have had difficulty weaning off a ventilator, followed by those who have suffered trauma or a catastrophic neurologic insult. [1] Infectious and neoplastic processes are less common in diseases that require a surgical airway.

Tracheostomy is a utilitarian surgical procedure of access; therefore, it should be discussed in light of the problem it addresses: access to the tracheobronchial tree. The trachea is a conduit between the upper airway and the lungs that delivers moist warm air and expels carbon dioxide and sputum. Failure or blockage at any point along that conduit can be most readily corrected with the provision of access for mechanical ventilators and suction equipment. In the case of upper airway obstruction, tracheostomy provides a path of low resistance for air exchange.

The traditional semantic difference between tracheostomy and tracheotomy is now blurred because the hole is variably permanent. If a cannula is in place, an unsutured opening heals into a patent stoma within a week. If decannulation is performed (ie, the tracheostomy cannula is removed), the hole usually closes in a similar amount of time. The cut edges of the tracheal opening can be sutured to the skin with a few absorbable sutures to facilitate cannulation and, if necessary, recannulation can be performed. Alternatively, a permanent stoma can be created with circumferential sutures. The term tracheostomy is used, by convention, for all these procedures and is considered to be synonymous with tracheotomy.

The trachea is nearly but not quite cylindrical but is flattened posteriorly.

In cross-section, it is D-shaped, with incomplete cartilaginous rings anteriorly and laterally, and a straight membranous wall posteriorly. The trachea measures about 11 cm in length and is chondromembranous. This structure starts from the inferior part of the larynx (cricoid cartilage) in the neck, opposite the 6th cervical vertebra, to the intervertebral disc between T4-5 vertebrae in the thorax, where it divides at the carina into the right and left main stem bronchi. For more information about the relevant anatomy, see Trachea Anatomy.


The advent of the antibiotic era and advances in anesthesia have made tracheostomy a commonly performed elective procedure. Indications include the following:

Congenital anomaly (eg, laryngeal hypoplasia, vascular web)

Upper airway foreign body that cannot be dislodged with Heimlich and basic cardiac life support maneuvers

Supraglottic or glottic pathologic condition (eg, infection, neoplasm, bilateral vocal cord paralysis)

Neck trauma that results in severe injury to the thyroid or cricoid cartilages, hyoid bone, or great vessels

Facial fractures that may lead to upper airway obstruction (eg, comminuted fractures of the mid face and mandible)

Upper airway edema from trauma, burns, infection, or anaphylaxis

Prophylaxis (as in preparation for extensive head and neck procedures and the convalescent period)

Severe sleep apnea not amendable to continuous positive airway pressure devices or other less invasive surgery

Tracheostomy may also be performed to provide a long-term route for mechanical ventilation in cases of respiratory failure or to provide pulmonary toilet in the following cases:

Inadequate cough due to chronic pain or weakness

Aspiration and the inability to handle secretions

The cuffed tube allows the trachea to be sealed off from the esophagus and its refluxing contents. Thus, this intervention can prevent aspiration and provide for the removal of any aspirated substances. However, some investigators argue that the risk of aspiration is not actually lessened, as secretions can leak around the cuffed tube and reach the lower airway.

The Council on Critical Care of the American College of Chest Physicians recommends tracheostomy in patients who are expected to require mechanical ventilation for longer than 7 days. [2] However, the final decision is made on an individual basis based on comorbidities and the patient’s current condition.


No absolute contraindications exist for tracheostomy. A strong relative contraindication to discrete surgical access to the airway is the anticipation that the blockage is a laryngeal carcinoma. The definitive procedure (usually a laryngectomy) is planned, and prior manipulation of the tumor is avoided because it may lead to increased incidence of stomal recurrence. Temporary tracheostomy may be performed just under the first tracheal ring in anticipation of a laryngectomy at a later time.

End-of-life issues may also come to bear on the decision to perform a tracheostomy because it may represent further mechanization of the patient’s care to family members. In fact, the performance of a tracheostomy does not affect the decision to extend or to withdraw care. Hygiene is improved, quality of life (speaking and eating, if relevant) is improved, and placement in long-term care is facilitated in some cases; however, dependence on mechanical ventilation may not be changed.

Technical Considerations

Procedure Planning

Tracheostomies can be performed through with an open or percutaneous technique. Open tracheostomy is one of the oldest procedures described in the literature and is still the procedure of choice for some trauma centers. However, the use of percutaneous tracheostomy has been increasing since its introduction in the 1980s.

Studies have supported percutaneous over open tracheostomies. However, the final technique depends on the surgeon’s experience and comfort, in addition to guidelines of the facility where this procedure is to be performed.

Complication Prevention

The cricothyroid muscle, vocal muscles, and the vocal cords are vulnerable to injury during tracheostomy (see the image below).

The innominate artery, or brachiocephalic trunk, crosses from left to right anterior to the trachea at the superior thoracic inlet and lies just beneath the sternum. The trachea is membranous posteriorly and is formed of semicircular cartilaginous rings anteriorly and laterally. The spaces between the rings are membranous.

The recurrent laryngeal nerves and inferior thyroid veins that travel in the tracheoesophageal groove are paratracheal structures vulnerable to injury if dissection strays from the midline (see the image below). The recurrent laryngeal nerve is also vulnerable to injury from the cuff of the tracheostomy tube, particularly if the cuff is overinflated.

The great vessels (ie, carotid arteries, internal jugular veins) could be damaged should dissection go far afield, which is a real risk in pediatric or obese patients. The thyroid gland lies anteriorly to the trachea with a lobe on both sides and the isthmus, which crosses the trachea at approximately the level of the second and third tracheal rings. This tissue is extremely vascular and must be divided with careful hemostasis.

Depending on the additives used, properties such as flexibility, opacity, color, heat stability, density, and chemical resistance can be controlled and modified

Has a high degree of biocompatibility and flexibility under changing temperatures and humidity [3]

Easily sterilized but prone to retention of bacteria and is therefore for single use/disposable

Silicone is a synthetic polymer and is produced by a cross-linked polymer reinforced with silica

Further cross-linking takes place by heating with a particular catalyst (ie, peroxide), to produce the required properties

Reduces adherence of secretions and bacteria to the tube by promoting easier passage for mucus

Can be sterilized but confined to single patient use

Cost effective for long-term use
