Target exams

Red flags

• A breastfed infant with a tongue-tie who is losing weight, becoming dehydrated, has few wet nappies or is jaundiced — feeding failure rather than a simple latch problem that needs supplemental expressed milk or formula, urgent lactation support and assessment, and consideration of early frenotomy.
• A mother with cracked, bleeding or distorted nipples, severe feeding pain, breast engorgement or mastitis that is not settling with skilled positioning and attachment — an untreated functional tongue-tie driving milk stasis and infection; reassess the infant's tongue mobility and involve a lactation consultant before the mastitis progresses.
• A submucous cleft palate masquerading as a posterior tongue-tie, or any midline oral anomaly with bifid uvula or a notched hard palate — do not divide a frenulum until a cleft has been excluded, because the tissue may be needed for later repair.
• An older child labelled tongue-tie whose real problem is speech delay from hearing loss, neurological hypotonia or an undiagnosed submucous cleft — investigate the cause rather than assume a frenulum explains the symptoms.

Board mappings

• General Paediatrics and neonatal care: ankyloglossia — definition, the anterior-versus-posterior classification, the link with breastfeeding difficulty, and the principle of lactation support before division.
• Infant feeding and growth: recognition of the infant with poor latch, poor weight gain and the mother with nipple trauma and mastitis, and timely lactation and ENT referral.
• Renewed curriculum — ENT and infant feeding: the lingual frenulum anatomy and latch biomechanics, the Hazelbaker and TABBY assessment tools, and the stepwise move from conservative support to frenotomy.
• Public health and systems: equitable access to lactation consultation and frenotomy, culturally safe breastfeeding support for Indigenous and remote families, and judicious use of a procedure whose rates are rising.
• General Paediatrics: recognition of the breastfed infant with feeding difficulty from tongue-tie, the differential of poor latch and nipple pain, and when to refer for lactation support and frenotomy.
• Acute care: the dehydrated or failing-to-thrive infant with a tongue-tie, and the mother with acute mastitis — resuscitation, supplemental feeding and escalation.
• Long Case / Structured discussion: an infant with ankyloglossia and breastfeeding difficulty — assessment, the decision to divide, the evidence for frenotomy, complications and the balance against overdiagnosis.
• Communication station: counselling a parent on tongue-tie — explaining that not every tie needs division, the role of lactation support, and the risks and benefits of frenotomy.
• Level 2 / 3 — ENT and infant nutrition: ankyloglossia, breastfeeding difficulty, assessment tools and the frenotomy decision.
• Health promotion: protecting breastfeeding through skilled support and appropriate, conservative use of frenotomy.
• Foundation of Practice (FOP): the definition and classification of tongue-tie, its effect on the breastfeeding latch, and the differential of poor latch and nipple pain.
• Applied Knowledge in Practice (AKP): the stepwise management, the frenotomy evidence and its limits, and the overdiagnosis and submucous-cleft red flags.
• History-taking and management: the mother with painful breastfeeding and the infant with poor weight gain, the assessment of tongue mobility and the management plan.
• Communication: counselling a parent on watchful waiting versus frenotomy, with a clear safety-net for weight gain and feeding.
• General Pediatrics Content Outline: ankyloglossia — definition, classification, association with breastfeeding difficulty, conservative management and frenotomy.
• Otolaryngology and Nutrition: anterior and posterior tongue-tie, validated assessment tools, the frenotomy decision and recognition of feeding failure.
• Patient Care: skilled lactation-led assessment of tongue-tie, conservative management first, and evidence-based use of frenotomy for persistent feeding difficulty.
• Systems-Based Practice and Population Health: equitable access to lactation consultation, culturally safe breastfeeding support, and stewardship of a procedure with rising utilisation.
• Medical Knowledge: the lingual frenulum anatomy, the latch biomechanics, the Hazelbaker and TABBY assessment tools, and the frenotomy technique and complications.
• Medical Expert: ankyloglossia diagnosis, classification, validated assessment, conservative and operative management, and recognition of feeding failure and submucous cleft.
• Health Advocate and Collaborator: breastfeeding support, culturally safe care for Indigenous and remote families, and timely lactation and ENT referral.
• Communicator: counselling a family on the balance of watchful waiting and frenotomy, with a safety-net for weight gain and feeding.
