macroglossia
Pronunciation: mak-ro-GLOS-ee-ah
Abnormally enlarged tongue that may cause breathing or feeding difficulties.
Full Definition
An abnormal enlargement of the tongue that is disproportionate to the oral cavity, potentially causing respiratory obstruction, feeding difficulties, and speech problems. In newborns, macroglossia can present as protruding tongue, drooling, and difficulty with latching for breastfeeding. The condition may be congenital (present at birth) or acquired, and can be associated with various syndromes including Beckwith-Wiedemann syndrome, Down syndrome, or hypothyroidism. Severe cases may require surgical reduction to prevent airway obstruction and improve feeding.
Usage
Usage note: Greek roots 'macro' (large) and 'glossia' (tongue); distinguish from tongue protrusion due to muscle weakness.
