This is a literature review of ankyloglossia and its correlation with lactation problems. Ankyloglossia, commonly referred to as tongue-tie, brings about functional difficulties and, in some cases, may lead to early weaning. It is crucial to use breastfeeding as the exclusive food source for the first six months of an infant's life, and the interference of the tongue contributes substantially to success in this regard. Even though there are many publications about ankyloglossia, there are still many controversies about its definition, diagnosis, classification, and treatment decision determined via frenotomy. Some researchers state that the identification of ankyloglossia should be based on morphological and anatomical evidence, while others claim that a short or tight frenulum should be examined in correlation with the impact on the mother-infant dyad during breastfeeding. By encouraging and supporting mothers in coping with feeding difficulties, their lactation experiences are improved, and they can continue breastfeeding.
