congenital laryngeal cleft
Introduction
Introduction to congenital laryngeal Laryngeal dysplasia, there is a fissure, called congenital laryngeal fissure, mostly occurs in the back of the larynx, the degree of laryngeal fissure is different, the light is only between the two sides of the sacral cartilage, and the other is the entire larynx, even The upper end of the trachea is completely split. The cause of this is not clear. Some people think that it may be related to congenital dysplasia of laryngeal tissue, and genetics is also a possible factor. It is also believed that there is a membranous knot in the middle of the laryngeal fissure. As the child grows, the magical tissue gradually relaxes when inhaling. If it is hemispherical inward, the laryngeal obstruction may occur, the compensatory breathing may be deepened, the flaky tissue may be loosened, the laryngeal obstruction may be aggravated, and the coughing during breastfeeding may cause suffocation and death. basic knowledge The proportion of illness: 0.06% Susceptible people: seen in infants and young children Mode of infection: non-infectious Complications: pneumonia, atelectasis, cleft lip, cleft palate
Cause
Cause of congenital laryngeal fissure
The cause of this is still unclear. Some people think that it may be related to the congenital dysplasia of the laryngeal tissue. Genetics is also a possible factor. It is also believed that there is a membranous knot in the middle of the laryngeal fissure. As the child grows, inhale. When the magical tissue gradually relaxes and protrudes in a hemispherical shape, the laryngeal obstruction may occur, the compensatory breathing may be deepened, the flaky tissue may be loosened, the laryngeal obstruction may be aggravated, and the coughing during breastfeeding may cause suffocation and death. .
Prevention
Congenital laryngeal crack prevention
The mortality of congenital laryngeal fissure is high, and the mortality rate is directly proportional to the degree of cracking. Early diagnosis and timely surgical repair are the key to reducing mortality.
The disease is a congenital disease and there are no effective preventive measures.
Complication
Congenital laryngeal complications Complications pneumonia, atlanto-occipital cleft palate
Often cause pneumonia, atelectasis and death, laryngeal fissure can be associated with other congenital malformations and cleft lip, cleft palate.
Symptom
Congenital laryngeal sparing symptoms Common symptoms Dysphagia, difficulty breathing, cough, esophageal fistula, atelectasis
Mild laryngeal fissure is generally asymptomatic. Severe laryngeal fissure often has throat, dysphagia, cough, dyspnea and cyanosis. If not treated promptly, pneumonia, atelectasis and death, laryngeal fissure and other congenital Malformation and cleft lip, splitting and so on.
Examine
Congenital laryngeal examination
Direct laryngoscopy: should pay attention to the situation between the iliac cartilage, carefully check whether there is a crack in the back of the throat.
Diagnosis
Diagnosis and diagnosis of congenital laryngeal
diagnosis
Diagnosis is difficult, especially when accompanied by other malformations such as cleft palate, tracheoesophageal fistula, it is not easy to think of the presence of laryngeal fissure, so children with throat, difficulty swallowing or eating cough, with or without other deformities, directly When laryngoscopy, attention should be paid to the condition of the iliac cartilage, and carefully check whether there is a crack in the back of the throat.
