New research raises questions as to whether too many infants are getting tongue-tie and lip tether surgery (also called frenulectomy) to help improve breastfeeding, despite limited medical evidence supporting the procedure. In a new study of 115 newborns referred for tongue-tie surgery, nearly 63% of children ended up not needing the procedure, and were able to successfully breastfeed following a thorough feeding evaluation from a multidisciplinary team of clinicians.
