Upper lip frenotomy for neonatal breastfeeding problems

Upper lip tie, without concomitant tongue tie, can prevent proper flanging of the upper lip during breastfeeding, resulting in a poor seal and suck for the infant with nipple pain and maternal dissatisfaction. Due to the lack of published studies on this subject, we report our technique and outcomes for in-office release of isolated upper lip tie.

Using CPT Code 40,806 for 'incision of labial frenulum', 22 mother-infant dyads with infant age under 60 days with breastfeeding problems and a restrictive upper lip frenum were identified. These infants underwent in-office release of upper lip tie as detailed below. Outcomes of the procedure were assessed by a telephone survey to mothers within the 4-week period post-procedure.

82% of mothers reported an improved latch and 73% noted increased satisfaction with breastfeeding. Lip pain, if present, resolved within 24 h for most children. Recurrence was reported by 9% of mothers; no infection or other complications occurred.

Upper lip frenotomy, in properly selected infants, has favorable short-term outcomes with mild transient discomfort and a low rate of recurrence. Since our study was short-term and did not include a control group, we are unable to comment on procedure efficacy or long-term impact.
