Airway stenosis

Introduction The respiratory tract is the passage through which the airflow passes when the lungs breathe. The respiratory tract of a lung vertebrate is divided into upper and lower parts: the nose, the sinuses, the pharynx and the larynx are called the upper respiratory tract. The trachea and its subsequent subdivisions are collectively referred to as the lower respiratory tract, or tracheal tree. Respiratory stenosis can be caused by inflammation caused by swelling and growth (polyps, etc.) leading to narrowing and narrowing of the respiratory tract.

Cause

1) Asthma: Inflammation caused by trachea, bronchial edema, spasm, resulting in insufficient air intake caused by airway stenosis (insufficient ventilation), resulting in difficulty breathing, to a more serious degree may even cause life-threatening.

2) Inflammation of the nasal cavity and throat: swelling and enlargement of the respiratory tract due to inflammation (polyps, etc.) cause the airway to become narrower and thinner, and rhinitis and throat inflammation cause edema, resulting in insufficient ventilation.

3) Foreign matter in the respiratory tract: Food or other foreign objects are stuck in the throat or into the respiratory tract, causing suffocation is also one of the causes of breathing difficulties.

The examination is performed by an electronic nose laryngoscope CT measurement or the like.

Respiratory stenosis can be caused by inflammation caused by swelling and growth (polyps, etc.) leading to narrowing and narrowing of the respiratory tract, also seen in oropharynx or nasopharyngeal benign or malignant tumors, rhinitis, nasal septum deviation, nasal polyps, nasal foreign bodies, nasal new organisms, Tonsil hypertrophy, overhanging sag, over-long, soft palate, thick tongue or fall, obese short neck, etc., should be distinguished for different causes of respiratory stenosis.
