Tracheal webs occur as a thin layer of tissue that narrows the tracheal lumen. They do not completely obstruct the trachea.

The incidence of congenital tracheal is 1:10,000 births.

Some patients will be asymptomatic. Symptomatic patients can present with cough, infection, wheezing, asthma, and/or shortness of breath.

There are two types of tracheal webs:

  • congenital
  • acquired: mostly post surgery or endotracheal intubation

A thin linear tracheal web can be seen on CT.

If symptomatic referral to an ENT surgeon for possible resection. Treatment can include various interventions via bronchoscopy, e.g. YAG Laser, mucosal sparing resections, stents 5.

  • tracheal stenosis: involvement of the tracheal cartilaginous rings
  • laryngeal stenosis
  • mucous in the trachea
    • this can be excluded by repeating and doing prone/ supine and/or inspiratory/expiratory CT scans to see the difference in appearance after coughing
