Ankyloglossia and infant feeding — branching viva

Opening — the two-week-old with a failing, painful breastfeed

Examiner: A two-week-old exclusively breastfed infant feeds for over an hour, clicks and pulls off, and has regained none of his birth weight. His mother has cracked bleeding nipples and an engorged tender breast. Talk me through your assessment and immediate actions. [2]

Candidate should cover: the principle that this is feeding failure first — secure the infant's intake with supplemental expressed breast milk or formula by an appropriate method, correct any dehydration, and arrange urgent lactation and paediatric review; the focused feeding history and the observation of a full feed; the oral examination of the frenulum and the functional tests of protrusion, elevation, cupping and lateralisation, looking for a compression stripe on the nipple; and the explicit exclusion of a submucous cleft palate by inspecting the uvula and hard palate before any thought of division. [10] [12]

Branch 1 — the conservative-first principle and the frenotomy decision

Examiner: There is a short, tight anterior frenulum that limits elevation and cupping, the palate is intact, and you have secured feeding and started lactation support. How do you decide whether to divide? [10]

Candidate should cover: the conservative-first principle — correct positioning and attachment, manage engorgement and mastitis, protect milk supply, and run an adequate trial of support with weight monitoring; the use of a validated functional tool such as the Hazelbaker HATLFF or the TABBY picture tool rather than a glance; and the indication for frenotomy only when there is persistent, function-limiting restriction and feeding difficulty after conservative care, with the Cochrane finding that frenotomy reduces maternal nipple pain (low certainty on infant outcomes) and the trial evidence supporting division in genuinely symptomatic ties. [1] [11]

Branch 2 — the suspected posterior tongue-tie

Examiner: Now a different infant: the frenulum looks normal at the tip, but the tongue pinches and dimples at the floor of the mouth on lifting, and the latch is painful and inefficient despite skilled support. What is the issue, and how do you handle it? [6]

Candidate should cover: a suspected posterior tongue-tie — felt more than seen, and a diagnosis that is harder and more contested, so an experienced assessor and a functional tool are essential before any division; the need to exclude a submucous cleft palate; and that if objective restriction and persistent feeding difficulty are confirmed, frenotomy can help, as shown in a randomised trial of posterior ties, while watchful support is correct where restriction is not confirmed. A recent meta-analysis supports improved breastfeeding outcomes after frenotomy in suitably selected infants. [6] [7]

Branch 3 — the six-week-old whose mother wants the tie snipped

Examiner: Finally, a six-week-old whose mother has read online that the baby is tongue-tied and wants it snipped today. Feeds are settling, the latch is painless and effective, and the infant is gaining weight along the ninth centile. There is a mild anterior frenulum with full tongue movement and an intact palate. How do you counsel her? [10]

Candidate should cover: the principle that a tie is treated for function, not appearance — an asymptomatic tie with effective painless feeding and normal weight gain needs no intervention; reassurance and continued breastfeeding support with weight monitoring; the overdiagnosis pitfall of rising frenotomy rates and internet-driven demand, and that exposing the infant to procedural risk for no benefit is inappropriate; the change in plan if the feeding were instead painful and inefficient with poor gain; and a clear safety-net to return for poor weight gain, painful feeding or mastitis.
