Pediatric Laryngeal Webs

A laryngeal web is a fibrous layer of tissue of varying thicknesses that develops in the larynx (voice box) and can affect the voice and breathing.

What are Pediatric Laryngeal Webs?

A laryngeal web is generally a congenital (present at birth) abnormality. It forms when the baby is developing in the early stages in the mother’s womb and fails to disappear as the baby continues to grow. A laryngeal web stretches between the vocal cords (also called vocal folds), which are located in the larynx. It restricts the trachea (windpipe), causing breathing difficulties and respiratory distress. It can also affect your child’s voice.

What are the signs and symptoms of Pediatric Laryngeal Webs?

Abnormal cry (weak, soft or absent)
Abnormal voice (high pitched or weak)
Chest infections
Croup (barking cough)
Hoarseness
Shortness of breath
Respiratory distress
Wheezing

What are the causes of Pediatric Laryngeal Webs?

In most cases, a laryngeal web is a congenital (present at birth) condition. Some children can develop one after long-term intubation, when a tube is inserted into the throat to help a baby or child breathe.
