Tongue-tie, or ankyloglossia, is poorly defined and involves a short, thick, fibrosed, or fixed lingual frenulum. Ankyloglossia has been reported to cause feeding difficulties, dysarthria, dyspnea, and social or mechanical problems. Ankyloglossia occurs in 1.7% of all neonates. As age advances, frenulum grows in length and normal function is established. Frenulectomy is recommended if it persists. We have also come across with the case of Tongue Tie in one of our patient. He is 19 years in age pursuing his graduation. He has got tongue tie which is persisting since birth. Keywords: Ankyloglossia; frenulum; frenulectomy.
