This observational, retrospective, cross-sectional study was conducted at Hospital General Guasmo Sur (Guayaquil, Ecuador) between September 2024 and February 2025, with the aim of establishing the relationship between breastfeeding difficulties and types of ankyloglossia according to the Coryllos scale. A total of 202 neonates with a gestational age of ≥ 28 weeks were enrolled; maternal and neonatal variables were collected, and multivariate logistic regression was used for statistical analysis. Mean neonatal weight was 3,142 ± 612 g and mean age was 12.3 ± 4.6 days. The most frequent breastfeeding difficulties were maternal pain (41.5%), poor latch (36.1%), and ineffective sucking (29.7%). A statistically significant association was found between type II ankyloglossia and early formula introduction (OR = 2.1; 95% CI: 1.1–4.0; p = 0.0187), indicating a negative impact of this condition on exclusive breastfeeding. These findings support the need to implement systematic neonatal screening and functional assessment to enable timely detection and management of ankyloglossia in the neonatal period.
