For decades, assessing and treating tongue-tie has been a controversial subject. Although lactation consultants have a keen appreciation for the need to treat this relatively uncommon structural abnormality, other health care providers do not share their level of concern. Parents often get caught or trapped between the recommendations of their LC and their primary health care provider. In this presentation, Dr. Hazelbaker presents the most up-to-date research on definition, assessment, treatment, and treatment outcome. She examines the on-going controversy and provides research based guidelines for the clinical decision-making process. Dr. Hazelbaker presents her own screening process, the Assessment Tool for Lingual Frenulum Function (ATLFF) and teaches participants how to use it properly (in longer versions of this presentation.) She also suggests ideas for cultivating a supportive team approach in communities where the practitioners remain ignorant of the pertinent research.
