Association of Feeding Evaluation With Frenotomy Rates in Infants With Breastfeeding Difficulties

Inpatient surgical release of lingual frenulums rose 10-fold between 1997 and 2012 despite insufficient evidence that frenotomy for ankyloglossia is associated with improvements in breastfeeding. Clear indications for surgical release remain murky, and best practice guidelines have yet to be developed.

To determine whether infants referred for frenotomy to treat breastfeeding difficulties should undergo procedures after comprehensive feeding examination, during which the primary cause of feeding issues was identified, and targeted intervention was provided.

This observational quality improvement study followed mother-infant dyads between March and December of 2018 who were referred to our tertiary care center for difficulty with breastfeeding. All infants underwent a comprehensive feeding evaluation by speech and language pathologists who examined the infants' ability to breastfeed prior to a surgical consultation for initial frenotomy. Data analysis was performed between January 2019 and May 2019.

A multidisciplinary feeding evaluation that examined infants' oral structure and function and their ability to breastfeed and that offered techniques for mothers to address any feeding difficulties prior to surgical intervention was developed. Infants either found success in feeding and weight gain through this program or underwent procedures.

The primary outcome was the percentage of frenotomy procedures following implementation of a multidisciplinary feeding team evaluation. The secondary outcome was the percentage of infants referred for lingual frenotomy who later had either combined lingual and labial frenotomy or labial frenotomy alone.

Included in the study were 115 patients (median age, 34 days [interquartile range, 19-56 days], 68 (59%) were male) referred for surgical division of the lingual frenum. Following the development of a program with feeding examination with a pediatric speech and language pathologist, 72 (62.6%) patients subsequently did not undergo surgical procedures. Although all of the referrals were for lingual frenotomy, 10 (8.7%) underwent labial frenotomy alone and 32 (27.8%) underwent both labial and lingual frenotomy.

The majority of patients referred for ankyloglossia may benefit from alternative intervention strategies following comprehensive feeding evaluation. Close collaboration and formation of multidisciplinary teams are imperative for treating these children.
