LACTATION SUPPORT FIRST, FRENOTOMY ONLY IF IT FAILS (RECOGNITION & REFERRAL)
Ankyloglossia (Tongue-Tie) - StatPearls (NCBI Bookshelf NBK482295) - https://www.ncbi.nlm.nih.gov/books/NBK482295/
No medicine treats a tongue-tie, so no drug row is offered. What the article does say is that the diagnosis is a functional one and that the commonest cause of a struggling feed is not the frenulum at all, so the order of work is: watch a feed, fix the position, involve someone who knows breastfeeding, and only then consider cutting.
- THE DIAGNOSIS IS FUNCTIONAL, NOT ANATOMICAL - a 2020 expert panel put it as tongue movement being limited by a frenulum that restricts it. And the article adds the qualifier: it is symptomatic tongue-tie, or symptomatic ankyloglossia, only once the lingual frenulum is limiting what the tongue can do. A frenulum that looks short on a baby who feeds well is not a diagnosis.
- WHAT TO EXAMINE - the examination has to show that tongue movement is restricted; typically the tongue cannot be pushed past the vermillion border. There may be a heart-shaped notch at the tip, and dimpling. And whichever assessment tool is used, the article insists on two things: that restricted movement is actually demonstrated, and that the lingual frenulum is the sole cause of it.
- WHAT THE PAIR ACTUALLY PRESENT WITH - in the baby: latching poorly, losing the latch again and again, fretful at the breast, and gaining weight badly. In the mother: pain on feeding, milk that does not come in adequately, or a breast that never empties because the suck is too weak. Examine her nipples too - the article lists infection, ulceration and bleeding.
- LOOK FOR THE COMMONER CAUSE BEFORE YOU BLAME THE FRENULUM - where a newborn is having trouble feeding, the other causes have to be excluded first, and the commonest of them by far is simply being positioned badly at the breast. A feed watched by someone experienced is worth more than any grading score.
- NOT EVERY TONGUE-TIE NEEDS SURGERY - not all of them require surgical management, and the conservative route must be put to the family: watching and waiting, a lactation consultation, and a speech pathology opinion.
- WHEN TO REFER FOR THE PROCEDURE - frenotomy is usually advised for an infant with ankyloglossia who is struggling to breastfeed once the conservative measures have been tried and failed. Releasing the frenulum early makes it less likely the mother gives up on breastfeeding altogether. So the referral is timed, not indefinite - a mother running out of patience is part of the indication.
- AND WARN THE FAMILY IT MAY NOT WORK - the evidence that frenotomy improves feeding difficulty in ankyloglossia is substantial, but some babies get no benefit from it at all, and the parents must be told that BEFORE the baby goes for surgery.
- BABIES WHO SHOULD NOT BE CUT WITHOUT SPECIALIST ASSESSMENT - the relative contraindications the article names are a neuromuscular disorder, hypotonia, retrognathia and micrognathia, because releasing the lingual frenulum in those babies can worsen glossoptosis, obstruct the airway and make swallowing harder. A small jaw or a floppy baby changes the answer.
- ASK ABOUT BLEEDING BEFORE, AND EXPECT NONE AFTER - take a family history of bleeding disorders before the procedure. Afterwards bleeding is the commonest problem, and local pressure usually settles it. The rarer ones the article names: obstruction of the airway, damage to the structures nearby, scarring, and aversion to anything in the mouth.
- DO NOT INJECT LOCAL ANAESTHETIC INTO AN INFANT'S FLOOR OF MOUTH - topical anaesthesia is of no benefit here, and local anaesthetic is CONTRAINDICATED in an infant. The article does note that some give sucrose beforehand, to take the edge off the pain.
- DO NOT PROMISE SPEECH OR TEETH WILL IMPROVE - how speech disorders relate to ankyloglossia stays unclear. There is only limited evidence that frenotomy produces good outcomes for anything besides breastfeeding. And on the bite: that tongue-tie contributes to malocclusion has only limited evidence behind it, and the belief may rest on nothing more than speculation. Feeding is the indication the evidence supports.
