New research published in JAMA Network Open indicates that the physical structure of a newborn’s upper lip frenulum does not influence breastfeeding success. A study of 264 mother–infant pairs at Oulu University Hospital found no correlation between the frenulum’s thickness or attachment site and reported breastfeeding difficulties, challenging the clinical necessity of routine lip-tie release procedures in healthy infants.
Why the link between lip-tie and breastfeeding is being questioned
For years, many parents and clinicians have linked breastfeeding challenges to the anatomy of the upper lip frenulum. However, the study led by neonatologist Outi Aikio found that 86% of mothers experienced breastfeeding difficulties regardless of the baby’s lip anatomy. According to the researchers, the anatomical characteristics of the frenulum—such as how thick or tight it appears—did not predict whether a mother would struggle with nursing during the first six months. This suggests that the current medical trend of performing surgical releases for lip-ties in healthy, full-term infants lacks a strong evidence base.
What actually impacts breastfeeding success?
The data suggests that maternal experience plays a larger role in breastfeeding outcomes than infant oral anatomy. Mothers who had previously breastfed other children reported fewer difficulties than first-time mothers, according to the study. This indicates that the learning curve for both parent and child is a more significant factor than structural variations in the infant’s lip. Rather than focusing on surgical interventions, Dr. Aikio emphasizes that high-quality, professional breastfeeding support during the early postnatal weeks remains the most effective way to address common nursing challenges.
How should parents approach breastfeeding difficulties?
If you are struggling with breastfeeding, clinical guidelines suggest a comprehensive assessment rather than jumping to surgical solutions. Many hospitals and lactation consultants now focus on maternal positioning, latch technique, and the mother’s confidence. According to the JAMA Network Open findings, the focus for healthy, full-term newborns should be on providing adequate support to the mother, particularly during the first few days of life, rather than evaluating the frenulum for potential surgery.
Frequently Asked Questions
Does a “lip-tie” always require surgery?
No. According to the research from Oulu University Hospital, there is no evidence to support routine lip-tie surgery in healthy, full-term infants, as structural features of the frenulum do not correlate with breastfeeding issues.
What is the most common cause of breastfeeding pain?
Breastfeeding difficulties are common in the early weeks and are often related to latch technique, maternal positioning, and the overall learning process, rather than the infant’s oral anatomy.
Are lip-tie releases becoming more common?
Yes. Despite limited evidence supporting their benefits, the frequency of lip-tie release procedures has increased in several countries over recent years, according to the study authors.
