Office-based frenotomy for ankyloglossia and problematic breastfeeding

Materials required

The following materials are needed for the procedure:

• gloves;

• a head lamp or pen light;

• sterile, straight, blunt-tipped scissors;

• 2-inch by 2-inch gauze pads;

• silver nitrate and 1:1000 adrenaline (in case of serious bleeding); and

• sterile saline solution to wet the gauze.

Technique for tongue-tie release

The following is the technique for office-based frenotomy for treatment of ankyloglossia:

• The assistant hooks his or her index fingers under the infant’s tongue and lifts the tongue superiorly to expose the lingual frenulum (Figure 1).

• Open scissors to a depth of 2 mm.

• Place the scissors against the frenulum away from the tongue and submandibular ducts and make a 2-mm cut into the tightest part of the frenulum (Figure 2).

• Push on the incision with an index finger to extend it fully (Figure 3). Figure 4 shows a fully released frenulum.

• The LC should help the baby to optimize latching immediately after the procedure.

Appearance of fully released frenulum

One potential pitfall is injury to the submandibular ducts, lingual artery, or genioglossus muscle. This technique minimizes damage to nearby structures and bleeding. Exercises should be done after the procedure to prevent reattachment of the frenulum. These involve the caregiver using his or her index finger to firmly push into the wound and upward in a J shape. This should be done 5 to 6 times per day for 7 to 10 days. Follow-up within 1 week of the procedure is recommended to check for reattachment of the frenulum. Figure 5 shows a wound healing normally 3 days after frenotomy.

Discussion

Learning this technique has allowed Dr Kenny-Scherber to help mothers and babies who are struggling with breastfeeding problems due to tongue-tie. This procedure is safe and effective, requires minimal materials, and can be very beneficial. Dr Newman has not experienced any episodes of substantial bleeding using this technique in his many years of practice. There have been rare cases of prolonged bleeding requiring suturing, but this can be prevented with good technique. Possible alternatives to this procedure are waiting, obtaining help from an LC, or referring the patient to another specialist who performs frenotomy.

This method of office-based frenotomy has not been previously described. A review of articles on PubMed using the search terms frenotomy and technique found a guideline from the National Institute for Health and Care Excellence describing the technique for division of ankyloglossia. It states that if done early in infancy no anesthesia is required. The method consists of the following: an assistant stabilizes the infant’s head; sharp, blunt-ended scissors are used to divide the frenulum; and the infant resumes feeding immediately after the procedure.⁴ Dr Newman’s technique is an extension of the National Institute for Health and Care Excellence technique, as it adds a manual push to extend the incision for complete release. There is debate in the literature about the need for topical anesthesia for frenotomy in newborns. The American Academy of Pediatric Dentistry states that while frenotomy can be accomplished without local anesthesia, topical anesthetic gel is highly recommended for pain and to alleviate parental concerns.⁵ Dr Newman has used topical anesthesia for frenotomy in the past but found that infants cried more and were unable to breastfeed immediately after the procedure. He now believes that breastfeeding and skin-to-skin contact immediately after frenotomy, as well as acetaminophen if needed, provide adequate analgesia for the procedure.

Conclusion

This office-based frenotomy technique is unique, easy to learn, and safe, and has been shown to be beneficial.
