RESULTS of the 304 newborns, 15 (4.9%) were considered with altered frenulum, and only 4 (26.7%) presented a low score in CEBE. The mean of the CEBE score was 9.3. (DP=1.35, Min=3, Max=10). Of the follow-up infants, only 2 (13.3%) persisted with breastfeeding difficulties for which frenotomy was indicated.
