What percent of infant epiglottis are OMEGA shaped?

The correct percentage of omega-shaped infant epiglottises is indeed 50%. This shape is common in infants due to their unique anatomical and physiological characteristics which differ from those of older children and adults.

In infants, the epiglottis is often more elongated and flexible, which allows it to function effectively in protecting the airway during swallowing. The omega shape—resembling the Greek letter omega—reflects this unique curvature and flexibility. This shape plays a crucial role in the anatomy of infants, particularly in the context of feeding and respiration, since their epiglottis can overlap the laryngeal opening more effectively during these processes.

Understanding that 50% of infant epiglottises are omega-shaped helps in recognizing the variability of anatomical structures in different age groups, and informs clinicians about expected norms in infant airway and feeding mechanics.
