Ankyloglossia, or tongue-tie, is a congenital malformation, in which a short, lingual frenulum or a tight genioglossus muscle restricts tongue movement. In newborns, the reported prevalence is 2-11%. However, only 18% of newborns, in whom clinical findings suggest ankyloglossia, develop symptoms. Several randomised clinical trials report a significant reduction in maternal nipple pain after frenotomy. Frenotomy is a low-procedure surgery, but the benefits are sparsely documented. Parents should be presented with risk and benefits, before a frenotomy is offered.
