2-week old neonate with a history of stridor that improves when the baby assumes the prone position – what is treatment –
## **Core Concept**
The question describes a 2-week-old neonate with stridor that improves in the prone position, which is suggestive of **laryngomalacia**. Laryngomalacia is a congenital condition characterized by soft and floppy tissues of the larynx (voice box) that can partially obstruct the airway, leading to stridor. It is the most common cause of stridor in infants.
## **Why the Correct Answer is Right**
The correct answer, **C. Observation and positioning**, is appropriate for laryngomalacia because this condition often resolves on its own as the child grows and the airway structures become more rigid. Positioning, such as placing the infant in a prone position, can help alleviate symptoms by allowing gravity to help keep the airway open. This condition typically does not require surgical intervention unless there are severe symptoms or complications.
## **Why Each Wrong Option is Incorrect**
- **Option A:** Surgical intervention (e.g., supraglottoplasty) might be considered in severe cases of laryngomalacia with significant symptoms or failure to thrive, but it is not the first line of treatment for most cases.
- **Option B:** This option is blank and cannot be evaluated.
- **Option D:** This option is also blank and cannot be evaluated.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that laryngomalacia is a diagnosis of exclusion. While the condition often presents with stridor that worsens with crying, feeding, or lying on the back, and improves with prone positioning, it's crucial to rule out other causes of stridor such as subglottic stenosis, vocal cord paralysis, or tracheomalacia. The condition usually resolves by 12-18 months of age.
## **Correct Answer:** . Observation and positioning
