Tracheal stenosis is a medical condition characterized by an abnormal narrowing or constriction of the lumen of the trachea, which can lead to respiratory distress and other related symptoms.

Surgical formation of an opening into the trachea through the neck, or the opening so created.

Developmental or acquired stricture or narrowing of the LARYNX. Symptoms of respiratory difficulty depend on the degree of laryngeal narrowing.

Endoscopic examination, therapy or surgery of the bronchi.

A procedure involving placement of a tube into the trachea through the mouth or nose in order to provide a patient with oxygen and anesthesia.

Tracheal neoplasms are abnormal growths or tumors that develop within the trachea, which can be benign or malignant, and have the potential to obstruct the airway and impair respiratory function.

Burns of the respiratory tract caused by heat or inhaled chemicals.

The cartilaginous and membranous tube descending from the larynx and branching into the right and left main bronchi.

Surgical incision of the trachea.

Any hindrance to the passage of air into and out of the lungs.

Congenital structural abnormalities of the respiratory system.

A species of baboon in the family CERCOPITHECIDAE found in southern equatorial and east Africa. They are smaller than PAPIO ANUBIS and have a thinner mane.

Abnormal passage between the ESOPHAGUS and the TRACHEA, acquired or congenital, often associated with ESOPHAGEAL ATRESIA.

A broad family of synthetic organosiloxane polymers containing a repeating silicon-oxygen backbone with organic side groups attached via carbon-silicon bonds. Depending on their structure, they are classified as liquids, gels, and elastomers. (From Merck Index, 12th ed)

The act of dilating.

Surgery performed on the lung.

Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX). (From Adams et al., Principles of Neurology, 6th ed, pp 822-3)

A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.

Tracheal diseases refer to a range of medical conditions that affect the structure, function, and integrity of the trachea, including inflammation, infection, trauma, tumors, and congenital abnormalities, which can lead to symptoms such as cough, wheezing, difficulty breathing, and stridor.

Devices that provide support for tubular structures that are being anastomosed or for body cavities during skin grafting.

Narrowing or constriction of a coronary artery.

Narrowing of the spinal canal.

The use of photothermal effects of LASERS to coagulate, incise, vaporize, resect, dissect, or resurface tissue.

An acquired disease of unknown etiology, chronic course, and tendency to recur. It is characterized by inflammation and degeneration of cartilage and can result in deformities such as floppy ear and saddle nose. Loss of cartilage in the respiratory tract can lead to respiratory obstruction.

Historically, a heterogeneous group of acute and chronic diseases, including rheumatoid arthritis, systemic lupus erythematosus, progressive systemic sclerosis, dermatomyositis, etc. This classification was based on the notion that "collagen" was equivalent to "connective tissue", but with the present recognition of the different types of collagen and the aggregates derived from them as distinct entities, the term "collagen diseases" now pertains exclusively to those inherited conditions in which the primary defect is at the gene level and affects collagen biosynthesis, post-translational modification, or extracellular processing directly.

A type of ALPHAPAPILLOMAVIRUS causing recurrent respiratory PAPILLOMATOSIS; GENITAL WARTS; and other neoplasms.

A circumscribed benign epithelial tumor projecting from the surrounding surface; more precisely, a benign epithelial neoplasm consisting of villous or arborescent outgrowths of fibrovascular stroma covered by neoplastic cells. (Stedman, 25th ed)
