Macroglossia is a disorder in which the tongue is larger than normal.
Macroglossia is most often caused by an increase in the amount of tissue on the tongue, rather than by a growth, such as a tumor.
This condition can be seen in certain inherited or congenital (existing at birth) disorders, including:
