There was significant correlation between epiglottis thickness and body surface area r0533 weight 0517 height 0437 and body mass index 0372. Aryepiglottic fold width of 59 mm or more was 923 sensitive and 808 specific. An estimate of the thickness of the epiglottis of the normal population.

The thickness of the EWB may be close to normal. Normal Thickness Ranges for the Adult Korean Epiglottis Using Ultrasonography. Wpr-198568 WPRIM ID.

2019 Baba et al. When the epiglottis becomes swollen and inflamed its called epiglottitis. The function of the epiglottis is to close the laryngeal inlet during swallowing and so to prevent the passage of food and liquid into the lungs aspiration.
