This study aimed to detect tongue edema induced by the pressure exerted by tonsillar retractor; edema detection was made through tongue area measurement using ultrasonography (USG) in pediatric patients who underwent tonsillectomy surgeries.

The tongue is an ideal organ for ultrasonography (USG) evaluation. This study aimed to detect the occurrence of tongue edema through USG examination and to educate clinicians about the association between subacute tongue edema and tonsillar retractor in pediatric patients.
