Ankyloglossia

Tongue-tie (ankyloglossia) is a condition present at birth that restricts the tongue's range of motion. With tongue-tie, an unusually short, thick or tight band of tissue (lingual frenulum) tethers the bottom of the tongue's tip to the floor of the mouth. A person who has tongue-tie might have difficulty sticking out his or her tongue. Tongue-tie can also affect the way a child eats, speaks and swallows, as well as interfere with breast-feeding.

Signs and symptoms of tongue-tie include Difficulty lifting the tongue to the upper teeth or moving the tongue from side to side, Trouble sticking out the tongue past the lower front teeth, a tongue that appears notched or heart shaped when stuck out

Typically, the lingual frenulum separates before birth, allowing the tongue free range of motion. With tongue-tie, the lingual frenulum remains attached to the bottom of the tongue. Why this happens is largely unknown, although some cases of tongue-tie have been associated with certain genetic factors.

Statistics: The reported prevalence varies from <1 percent to 10.7 percent. Most series identify an increased frequency in boys with a male to female ratio of 1.5:1 to 2.6:1. 60% of otolaryngologists and 50% of speech pathologists answered that ankyloglossia is sometimes associated with speech difficulties compared to only 23% of pediatricians; 67% of otolaryngologists compared with 21% of pediatricians answered that ankyloglossia is sometimes associated with social and mechanical difficulties. Limitations of this study include a reduced sample size due to unreturned or incomplete surveys.
