Laryngotracheal cicatricial stenosis

Introduction to laryngotracheal scarring Carytrical stenosis (cicatricialstenosisoflarynxandtrachea) refers to a pathological state in which the airway is narrowed due to hyperplasia of the larynx and/or the tracheal cavity, and its main physiological function is impaired. It is a common disease of chronic laryngotracheal obstruction, mostly caused by trauma. The disease should be differentiated from congenital subglottic stenosis. Patients with laryngotracheal scar stenosis are mainly dyspnea, hoarseness and wheezing. Indirect laryngoscopy can be seen in laryngeal cavity deformation, vocal cord marking is unclear, scar hyperplasia or adhesion, limited or completely fixed activity, X-ray lateral radiograph, tomographic or CT-defined stenosis, extent, extent, presence or absence of cartilage scaffold defect , displacement, is important for guiding surgery. basic knowledge The proportion of illness: 0.002% Susceptible people: no specific population Mode of infection: non-infectious Complications: congenital subglottic stenosis

Causes of laryngotracheal scarring

(1) Laryngeal trauma: common in throat contusion, crushing, cutting injury, firearm injury, chemical burns, etc.

(2) iatrogenic injury: such as tracheotomy, intubation injury, artificial respiration with balloon intubation.

(3) sequelae of laryngeal surgery: various half-throatectomy, vocal cord tumor surgery.

(D) neck tumor surgery: thyroidectomy damage bilateral recurrent laryngeal nerve, although there is no scarring, but there are similar treatments.

Laryngeal tracheal scar stenosis prevention

The laryngotracheal stenosis is complicated, variable, and more common in children, and treatment is more difficult. Therefore, it is equally important to choose appropriate treatment methods and effective preventive measures.

Complications of laryngotracheal scar stenosis Complications congenital subglottic stenosis

Usually, as a long-term endotracheal intubation, complications such as inappropriate intralaryngeal surgery and partial laryngectomy occur, and severe breathing causes difficulty in breathing.

Throat tracheal scarring symptoms common symptoms dyspnea airway narrowing

The patients were mainly dyspnea, hoarseness and wheezing.

Examination of laryngotracheal scar stenosis

Indirect laryngoscopy can be seen in laryngeal cavity deformation, vocal cord marking is unclear, scar hyperplasia or adhesion, limited or completely fixed activity, X-ray lateral radiograph, tomographic or CT-defined stenosis, extent, extent, presence or absence of cartilage scaffold defect , displacement, is important for guiding surgery.

Diagnosis and differentiation of laryngotracheal scar stenosis

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

And congenital subglottic stenosis identification, laryngotracheal scar stenosis patients mainly dyspnea, hoarseness and wheezing.
