Influence of frenotomy on breastfeeding in newborns with ankyloglossia

Purpose: evaluate the influence of frenotomy on the breastfeeding of newborns diagnosed with ankyloglossia. Methods: this is an intervention study performed with 50 newborns diagnosed with ankyloglossia. It was conducted in three stages: diagnosis, intervention and reassessment. In the diagnostic phase, the Protocol for the Assessment of Speech Language with Scores for Babies was applied to diagnose ankyloglossia and a questionnaire assessing the symptoms and coordination of sucking, swallowing and breathing during breastfeeding. In the intervention, frenotomy was performed, and at reassessment, the diagnostic protocol and questionnaire in order to compare the post-surgical effects. Results: of the 50 babies participating in the study, 35 (70%) were boys and 15 (30%) girls. A total of 68% of ankyloglossia cases were reported in the family, a majority (38%) involving cousins. There was a statistically significant reduction in the average protocol score in the reassessment stage, from 8.38 (7-12 points) to 0.86 (0-5 points), as well as a statistically significant improvement in all variables related to the symptoms of breastfeeding. Conclusion: surgical intervention, known as frenotomy, made it possible to improve the negative symptoms of breastfeeding in newborns diagnosed with ankyloglossia.
