Evaluation of Anatomic Features and Assessment Tools to Determine Treatment of Ankyloglossia

Purpose: To evaluate the use of lingual frenotomy assessment tools and the anatomical features most commonly used by dentists and otolaryngologists to determine if a frenotomy was indicated.
Methods: A nine-question survey was distributed to American Academy of Pediatric Dentistry members and otolaryngologists in the American Medical Association. The survey consisted of three categories: (1) demographics; (2) use of a standardized assessment tool; and (3) assessing anatomical features for frenotomy. Three different cases of ankyloglossia were given to assess which anatomical features were used to determine if a frenotomy was needed.
Results: Subjects included 404 practitioners. The most common frenotomy assessment tool utilized was the Hazelbaker assessment tool, followed by the LATCH and Bristol tongue assessment tools. The anatomical features used by most responders in determining if a frenotomy was indicated were the appearance of the tongue when lifted, tongue protrusion, frenulum length, and frenulum type.
Conclusions: Many practitioners believe frenotomies for ankyloglossia are indicated when there is a functional impairment and an anatomical component. This study suggests that the general appearance of the tongue when lifted is the most common anatomical feature used for assessing the need for a frenotomy.
