Is Laryngomalacia a congenital anomaly?

Can I feel my cricoid cartilage?

Put your finger on tip of your chin and slide that finger down the midline. The first structure you hit is the top of the thyroid cartilage, which despite its name, is not where the thyroid gland is situated. Keep moving your finger down your neck to the Adam’s apple. Just beyond you will feel the cricoid cartilage.

What is the rima glottidis?

The rima glottidis is the potential space between the vocal ligaments contained within these intrinsic ligaments and membranes. Serving as the primary conduit for airflow within the larynx, the rima glottidis may be open or closed secondary to abduction or adduction of the vocal folds, respectively.

What does laryngomalacia look like?
