Effect of frenotomy on breastfeeding and reflux: results from the BRIEF prospective longitudinal cohort study

Objectives To assess the Efficacy of Frenotomy with regard to Breastfeeding and Reflux Improvement (BRIEF) in infants with breastfeeding problems. Materials and methods A cohort of 175 consecutive breastfeeding women with breastfeeding and reflux problems related to a tongue-tie or lip-tie fulfilling the inclusion criteria was longitudinally followed for 6 months. The effect of frenotomy on these problems was studied by a standardized oral assessment and completing the validated Breastfeeding Self-Efficacy Short Form (BSES-SF), nipple pain score (Visual Analogue Scale, VAS), and Infant Gastroesophageal Reflux Questionnaire Revised (I-GERQ-R) questionnaires pre-frenotomy and at 1 week, 1 month, and 6 months’ post frenotomy. Results All 175 women completed the 1-month follow-up and 146 women the 6 months’ follow-up. Frenotomy resulted in a significant improvement of BSES-SF, nipple pain score, and I-GERQ-R after 1 week, which improvement maintained to be significant after 1 month for BSES-SF and I-GERQ-R, and after 6 months for I-GERQ-R. The improvements were irrespective of the type lip-tie or tongue-tie underlying the breast feeding and reflux problems. No post-operative complications were observed. About 60.7% of infants still was breastfed 6 months after treatment. Conclusions Frenotomy is a safe procedure with no post-operative complications and resulting in significant improvement of breastfeeding self-efficacy, nipple pain, and gastro-oesophageal reflux problems. Clinical relevance Frenotomy of a tongue-tie and or lip-tie can lead to improvement of breastfeeding and reflux problems irrespective of the type of tongue-tie or lip-tie and should be considered by clinicians as a proper tool to resolve these problems if non-interventional support did not help.
