Development of an Assessment Method for Obstructive Tonsillar Hypertrophy in Children by Ultrasonography

Chronic tonsillar hypertrophy is one of the most common causes of upper airway obstruction in children. Currently, several clinical staging systems are used to evaluate airway obstruction due to tonsillar hypertrophy. However, as these staging systems are based on a physical examination, it is not always possible to accurately evaluate the tonsil size, especially in children, and so objective and reliable methods are required in this field. In this study, the investigators aimed to develop a new method for the objective evaluation of airway obstruction due to tonsillar hypertrophy using submental ultrasonography (US) in children.
