Tongue and lip tie: the Game Changer Studies

Presented by Alison Hazelbaker

This event was originally broadcast on:

September 5th 2019, 12 PM, CT


Updated with two new studies.


Dr. Hazelbaker presents on several change-maker studies regarding the subjects of tongue-tie and lip-tie. She includes previously unknown studies from 1971 to 1995 and combines their findings with more recent studies. Participants will be surprised, delighted and maybe even disgruntled about the conclusions made in these studies. All, however, change the way we think about these subjects!





1. The participant will be able to discuss a gamechanger study about the histology of the lingual frenum.

2. The participant will be able to describe the research showing that maxillary lip tie does not exist.

3. The participant will be able to discuss both the AHRQ and Cochrane studies that show only a slight benefit of frenotomy for breastfeeding issues.




1. Game-changers

                  a. Multiple studies that change the way we think about tongue and lip tie

                  b. It isn’t just about infant feeding, its about development

2. Histology

                  a. Lingual frenum

                  b. Two studies that corroborate one another

                  c. Myths stricken down by these studies

3. Wound healing

                  a. the three phases

                  b. Studies that show that wounds are best left alone

                  c. The implication relative to disturbing the fibrin clot post frenectomy

4. Oro-facial impact

                  a. Sleep apnea

                  b. Mid-face development

5. Impact of frenotomy on breastfeeding

                  a. Ultrasound studies

                  b. Before and after impact

                  c. Corroboration

6. Maxillary labial frenum

  1. Lots of great information! 5 Star Review

    Posted by on 19th Sep 2019

    The information presented was definitely so important to anyone who is assessing nursing babies for Tongue Tie. I would say that it would be helpful to include a reference diagram or model for the anatomical structures as they are being discussed. Not everyone uses the same names for the same anatomical structures, and even when I was cross referencing with the web, and the recording of the webinar, I found the name often leads to images of nerves, or circulatory structures, rather than the body parts we are actually trying to discuss.
