Congenital subglottic stenosis

Introduction to congenital subglottic stenosis The diameter of the subglottic cavity of normal infants is 5.5-6 mm. Due to abnormal development and narrow subglottic cavity, it is called congenital subglottic stenosis. It is one side or both sides of the subglottic wall. Most of them are elastic conical lesions. However, it is also caused by abnormal cartilage. The common symptoms are that the baby has a sound after the birth, but the crying is normal. The degree of difficulty in breathing is determined according to the obstruction. The severe stenosis can cause neonatal asphyxia. The child is often prone to respiratory infection or laryngitis. It is easily misdiagnosed as acute. Laryngeal tracheobronchitis. The disease needs to be differentiated from acute laryngitis, bronchitis and bronchitis. Tracheitis is an inflammatory change of the trachea and bronchus caused by infection or non-infectious factors. The secretion of mucus is increased. The activity of respiratory enzymes in the epithelial villus of the trachea is reduced due to the lack of negative ions, which affects the secretion function of the alveoli and the ventilation and exchange of the lungs. Gas function. basic knowledge The proportion of illness: 0.001% Susceptible people: young children Mode of infection: non-infectious Complications: laryngitis, respiratory infection, neonatal asphyxia

Congenital subglottic stenosis

Due to dysplasia, the subglottic cavity is narrow and causes obstruction.

Congenital hypoglossal stenosis prevention

The disease is a congenital disease, no effective preventive measures, early diagnosis and early treatment is the key to the prevention and treatment of this disease.

Congenital subglottic stenosis Complications, laryngitis, respiratory infection, neonatal asphyxia

Children are often susceptible to respiratory infections or laryngitis.

Congenital subglottic stenosis symptoms Common symptoms Dyspnea, asphyxia, glottic dyskinesia, itchy throat

The common symptoms are that the baby has a sound after the birth, but the crying is normal. The degree of difficulty in breathing is determined according to the obstruction. The severe stenosis can cause neonatal asphyxia. The child is often prone to respiratory infection or laryngitis. It is easily misdiagnosed as acute. Laryngeal tracheobronchitis.

Congenital hypoglottic examination

Direct laryngoscopy showed that the structures of the larynx were small, the glottis was short and narrow, and the thyroid cartilage in the neck was smaller than normal.

Diagnosis and diagnosis of congenital subglottic stenosis

The disease needs to be differentiated from acute laryngitis, bronchitis and bronchitis. Tracheitis is an inflammatory change of the trachea and bronchus caused by infection or non-infectious factors. The secretion of mucus is increased. The activity of respiratory enzymes in the epithelial villus of the trachea is reduced due to the lack of negative ions, which affects the secretion function of the alveoli and the ventilation and exchange of the lungs.
