Tongue Function Characteristics in Infants Experiencing Breastfeeding Difficulties and Changes in Breastfeeding After Frenotomy Procedures

Objectives: The aims of the study were to describe tongue function in infants experiencing breastfeeding difficulties and to examine changes in breastfeeding after frenotomy procedures.

Materials And Methods: Mothers, and their infants, facing difficulties in breastfeeding were referred to the Vilnius University hospital Žalgirio clinic after assessment of breastfeeding quality by a lactation specialist. Anatomy evaluations included the type of ankyloglossia, tongue function, and the need for a frenotomy. All mothers completed the breastfeeding questionnaire twice, once during the referral consultation and 1 month later. The total breastfeeding hindrance score was calculated before and after the frenotomy.

Results: Fifty infants were included in the study and their mean age was 29.6 days (min age 1 day and max 78 days). The male to female ratio was 1.8:1.0. Of all infants, 70% had severe lingual function alterations and their mothers were facing issues in breastfeeding. After the frenotomy, there was a significant reduction in breastfeeding hindrance in infants who had disturbed function and aberrant anatomic characteristics. It was found that for type II ankyloglossia, the frenotomy procedure was significant more (p = 0.002) beneficial, than for type I ankyloglossia. After the frenotomy, there was a significant improvement in nine out of 14 criteria of breastfeeding (p = 0.001).

Conclusions: Frenotomy procedures had a positive effect on improving breastfeeding.

Clinical Relevance: Current study analyses issues with breastfeeding. Dental practitioners and pediatricians should be familiar with this topic, as early and timely minimal invasive surgical intervention has a significant impact for better comfort of the mothers and continuation of breastfeeding.
