WHAT Is trachea????????
Answers
Answer:
a large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs; the windpipe.

Answer:
Tracheal stenosis: Inflammation in the trachea can lead to scarring and narrowing of the windpipe. Surgery or endoscopy may be needed to correct the narrowing (stenosis), if severe.
Tracheoesophageal fistula: An abnormal channel forms to connect the trachea and the esophagus. Passage of swallowed food from the esophagus into the trachea causes serious lung problems.
Tracheal foreign body: An object is inhaled (aspirated) and lodges in the trachea or one of its branches. A procedure called bronchoscopy is usually needed to remove a foreign body from the trachea.
Tracheal cancer: Cancer of the trachea is quite rare. Symptoms can include coughing or difficulty breathing.
Tracheomalacia: The trachea is soft and floppy rather than rigid, usually due to a birth defect. In adults, tracheomalacia is generally caused by injury or by smoking.
Tracheal obstruction: A tumor or other growth can compress and narrow the trachea, causing difficulty breathing. A stent or surgery is needed to open the trachea and improve breathing.

Trachea Tests
Flexible bronchoscopy: An endoscope (flexible tube with a lighted camera on its end) is passed through the nose or mouth into the trachea. Using bronchoscopy, a doctor can examine the trachea and its branches.
Rigid bronchoscopy: A rigid metal tube is introduced through the mouth into the trachea. Rigid bronchoscopy is often more effective than flexible bronchoscopy, but it requires deep anesthesia.
Computed tomography (CT scan): A CT scanner takes a series of X-rays, and a computer creates detailed images of the trachea and nearby structures.
Magnetic resonance imaging (MRI scan): An MRI scanner uses radio waves in a magnetic field to create images of the trachea and nearby structures.
Chest X-ray: A plain X-ray can tell if the trachea is deviated to either side of the chest. An X-ray might also identify masses or foreign bodies.

Trachea Treatments
Tracheostomy: A small hole is cut in the front of the trachea, through an incision in the neck. Tracheostomy is usually done for people who need a long period of mechanical ventilation (breathing support).
Tracheal dilation: During bronchoscopy, a balloon can be inflated in the trachea, opening a narrowing (stenosis). Sequentially larger rings can also be used to gradually open the trachea.
Laser therapy: Blockages in the trachea (such as from cancer) can be destroyed with a high-energy laser.
Tracheal stenting: After dilation of a tracheal obstruction, a stent is often placed to keep the trachea open. Silicone or metal stents may be used.
Tracheal surgery: Surgery may be best for removing certain tumors obstructing the trachea. Surgery may also correct a tracheoesophageal fistula.
Cryotherapy: During bronchoscopy, a tool can freeze and destroy a tumor obstructing the trachea.
