Tongue tie - ankyloglossia (Children)
👅🍼 Tongue-tie (ankyloglossia) is a congenital condition in which a short, tight lingual frenulum restricts tongue movement.
✂️ Tongue-tie division (frenotomy) is a safe, quick procedure that can significantly improve breastfeeding difficulties when the tongue-tie is functionally relevant. It is usually completed in seconds and is generally well tolerated.
📘 About
- 👶 Recognised cause of feeding difficulties in infants.
- 🍼 Commonly associated with poor latch, prolonged feeds, and maternal nipple pain.
- ⚖️ Many tongue-ties are asymptomatic - function matters more than appearance.
🧬 Aetiology
- 👅 Short, thick, or tight lingual frenulum restricting tongue elevation and protrusion.
- 📊 Seen in up to 5–10% of newborns.
- 🧠 Can interfere with the infant’s ability to generate negative pressure during feeding.
🩺 Clinical Features
- 🍼 Poor latch or frequent detachment during breastfeeding.
- ⏱️ Prolonged feeds with poor weight gain.
- 🤱 Maternal nipple pain, trauma, or mastitis.
- 👅 Tongue appears tethered, heart-shaped on protrusion, or unable to elevate.
- 🔍 May be subtle - often requires structured assessment rather than inspection alone.
🧪 Investigations
- 🩺 Clinical diagnosis - no routine blood tests or imaging required.
- 📋 Functional assessment tools (e.g. Hazelbaker score) may support decision-making.
💊 Management
- 🎯 Indication for treatment: tongue-tie causing functional feeding problems (not appearance alone).
- 🤝 Early input from a lactation consultant is essential and may resolve mild cases.
- ✂️ Frenotomy:
- 👶 <8 months: quick bedside procedure, usually no anaesthetic required.
- 🧒 >9 months: often requires general anaesthetic due to cooperation and anatomy.
- 🩹 Minimal bleeding; feeding can usually resume immediately after the procedure.
🧠 Teaching & Exam Pearls
- ⚠️ Not all tongue-ties need division - symptoms guide management.
- 🍼 Breastfeeding problems + maternal nipple pain should prompt tongue-tie assessment.
- 📉 Early treatment can prevent feeding failure and unnecessary formula supplementation.
- 🗣️ Evidence for speech improvement is weaker - feeding benefit is the main indication.
✅ Summary
Tongue-tie is a common and often overlooked cause of infant feeding difficulty. Management should focus on functional impact, with early lactation support and selective use of frenotomy. When appropriately indicated, tongue-tie division is a safe and effective intervention with rapid benefit.
