Ankyloglossia is a developmental condition present at birth in which the lingual frenulum—the membrane connecting the underside of the tongue to the floor of the mouth—is unusually short, tight, or thick. This tethering can vary from a thin mucous membrane band to a total fusion of the tongue to the mouth floor, often resulting in a heart-shaped appearance when the patient attempts to protrude the tongue. Clinical complications include breastfeeding difficulties in infants (e.g., poor latch or maternal nipple pain) and potential speech impediments or mechanical issues like difficulty licking the lips in older children.
greek The term is derived from two Ancient Greek roots that describe the physical “tethering” of the organ:
-Ankylo-: From the Greek ankýlos, meaning “bent,” “crooked,” or “loop,” and in medical contexts, “stiff” or “fused”.
-glossia: From the Greek glōssa, meaning “tongue”.
Suffix: The suffix -ia denotes a medical condition or state.
