TRACHEOMALACIA
Tracheomalacia commonly involves most of the trachea and other major airways.
wheeze, cough, stridor, dyspnea, tachypnea, cyanosis, recurrent respiratory tract infections.
Congenital diffuse malacia of the airway improves by age 6–12 months.
The structural integrity of the trachea is restored gradually.
TRACHEOMALACIA
Type I : congenital or intrinsic tracheal abnormalities associated with a tracheoesophageal fistula or esophageal atresia.
Type II : extrinsic defects or anomalies, vascular ring causing undue pressure on the trachea.
Type III : acquired tracheomalacia , with prolonged intubation, chronic tracheal infections, or inflammatory conditions like relapsing polychondritis.
TRACHEOMALACIA
Lateral fluoroscopy ,esophagogram diagnostic.
Fluoroscopy:
Cine computed tomography (CT Scan)
Endoscopy

NARROWED IN ALL STUDIES
TRACHEAL STENOSIS
Tracheal stenosis affects 4-13 % of adults
1-8 % of neonates after prolonged intubation .
adult tracheal stenosis : trauma, chronic inflammatory diseases, benign neoplasm, malignant neoplasm and collagen vascular diseases.
TRACHEAL STENOSIS
The most common cause of tracheal stenosis trauma, which can be internal (prolonged
endotracheal intubation, tracheostomy, flame burn injury) or external (blunt or penetrating
90 % of all cases of acquired chronic subglottic stenosis in children and adults result from endotracheal intubation or tracheostomy.1
TRACHEAL STENOSIS
TRACHEAL STENOSIS
TRACHEAL BRONCHUS A right upper bronchus
originating in the trachea
a variety of bronchial anomalies arising in the trachea or main bronchus, directed toward the upper-lobe territory.
The right lateral wall of the trachea less than 2 cm above the major carina , supply the entire upper lobe or its apical segment.
Tracheal bronchus may be displaced or supernumerary .
TRACHEAL BRONCHUS
TRACHEOBRONCHOMALACIA
An abnormal collapse of tracheal and bronchial walls on expiration.
Primary : intrinsic to the tracheobrochial tree.
Bronchoscopy
Cartilage to membrane ratio 4.5:1 to 2:1
Premature infant.
TRACHEOBRONCHOMALACIA Secondary: extrinsic pathologies, compression or damage to the
airway Esophageal atresia/ tracehobronchial
fistula A vascular anomaly A congenital cardiac defect Cystic lesion, bronchogenic cyst.
TRACHEOESOPHAGEAL FISTULA
A congenital or acquired communication between the trachea and esophagus.
Often lead to severe and fatal pulmonary complications.
Most patients with TEF are diagnosed immediately following birth or during infancy (neonatal period).
TRACHEOESOPHAGEAL FISTULA
Acquired TEF secondary to malignant disease. Infection, ruptured diverticula, trauma.
17-70% children with TEF have associated developmental anomalies.
Down syndrome, duodenal atresia, cardiovascular defect
TRACHEOESPHAGEAL FISTULA
Copious, fine white frothy bubbles of mucus in the mouth and nose.
Secretion recur despite suctioning
Rattling respiration, episode of coughing and choking associated with cyanosis.
Worsen during feeding
Abdominal distension
