The role of tongue-tie in breastfeeding problems-A prospective observational study.

ABSTRACT

AIM: We evaluated what determined breastfeeding problems in a non-selected mother-infant cohort, with special reference to tongue-tie and improvements in breastfeeding following frenulotomy. METHODS: This 2014-2015 prospective, observational study was carried out in a tertiary level maternity unit affiliated to the University of Freiburg, Germany, using a breastfeeding questionnaire, standardised breastfeeding scores and the Assessment Tool For Lingual Frenulum Function (ATLFF). The standard intervention was breastfeeding support, a frenulotomy for tongue-tie was performed if necessary. All cases of breastfeeding problems and, or tongue-tie, were followed up by telephone 2.5 weeks after birth. RESULTS: We enrolled 776 newborn-mother dyads 345 had breastfeeding problems, 116 had a tongue-tie and 30 underwent a frenulotomy. In the multivariate analysis, severe breastfeeding problems were more frequent in newborn infants with tongue-tie, with an odds ratio (OR) of 2.6 (P= 0.014). Other risk factors were no breastfeeding experience (OR 4.4, P = 0.001), low birth weight (OR 2.9, P = 0.001), prematurity (OR 3.6, P = 0.000) and Caesarean section (OR 1.6, P = 0.023). There was a significant reduction in breastfeeding problems after frenulotomy (P = 0.01). CONCLUSION: Tongue-tie had a significant impact on breastfeeding and so did low birth weights and prematurity. Frenulotomy proved helpful when breastfeeding problems were reported.
