ANKYLOGLOSSIA IN INFANTS: FUNCTIONAL IMPACTS AND REPERCUSSIONS ON BREASTFEEDING

Abstract

Introduction: Ankyloglossia is a congenital alteration characterized by restricted lingual mobility, which can compromise vital oral functions in infants, particularly breastfeeding. Objective: To analyze the functional impacts of ankyloglossia on breastfeeding and evaluate evidence regarding early diagnosis and therapeutic interventions. Methodology: A narrative literature review based on scientific articles published between 2021 and 2025, focusing on functional aspects, diagnostic methods, and frenotomy outcomes. Results: Literature converges on the understanding that ankyloglossia acts as a functional barrier to milk transfer, causing maternal pain and infant fatigue. Frenotomy has proven to be an effective intervention, with significant improvement in latch and breastfeeding maintenance. Discussion: Clinical management requires an individualized approach, combining clinical diagnosis with assessment of breastfeeding dynamics. Although frenotomy shows consolidated benefits, there is a need for greater standardization of protocols and evaluation of conservative approaches. Conclusion: Ankyloglossia requires timely diagnosis and intervention based on functional criteria to promote maternal-infant health. Future studies are needed to refine therapeutic indications.
