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 Zalgirio 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.
