From Assessment to Complete Release: A Data-Driven, Hands-On Approach to Scissor Frenotomy and Objective Surgical Checkpoints Across Ages
Tongue tie surgery is often discussed in terms of whether a release should be performed, yet far less attention is given to the practical questions that determine whether treatment is complete, reproducible, and functionally meaningful: What exactly are we assessing? What anatomical restriction are we releasing? What should change during the procedure? And how do we know when we are finished?
This 90-minute interactive session will translate Dr. Alison Sigal’s clinical research, surgical protocols, and experience caring for more than 4,000 patients into a practical framework for frenotomy across infants, children, adolescents, and adults.
Central to this approach is understanding the tongue as a muscular hydrostat. As explored in Dr. Sigal’s peer-reviewed publication, Changes in Tongue Resting Posture Following Pediatric Lingual Frenotomy: Evidence for the Tongue as a Muscular Hydrostat, an unrestricted tongue possesses an inherent ability to change shape, elevate, broaden, and rest passively in complete contact with the full length of the hard palate. The surgical goal is therefore not simply division of a frenum, but removal of the mechanical restriction preventing the tongue from expressing this natural function.
This anatomical and physiological framework provides the foundation for objective surgical checkpoints that can simplify intraoperative decision-making and help clinicians determine when complete release has been achieved. Participants will learn to distinguish simply dividing a restricted lingual frenum from achieving unrestricted separation of the tongue from the floor of the mouth while the underlying floor remains broad and flat, followed by assessment of passive full-palate suction.
The evolving Tool for Optimal Tongue Rest Posture (TOTRP) will also be reviewed as an objective, measurement-based surgical checkpoint that connects tongue mobility to each patient’s individual palatal anatomy, providing an objective framework to support intraoperative decision-making and assessment of release completeness.
Dr. Sigal’s preference for scissors will be reviewed, including the tissue control, tactile feedback, and sequential release they provide within her technique. However, the anatomical assessment, functional goals, progressive release principles, and objective surgical checkpoints presented are not instrument dependent and can be applied regardless of whether scissors, laser, or another surgical instrument is used.
These concepts will be demonstrated across both awake and anesthetized frenotomy care, using clinical photographs, surgical videos, clinical cases, and step-by-step surgical decision-making.
The goal is not to teach a single incision or instrument. It is to use anatomy and physiology to help clinicians see, assess, release, reassess, and objectively determine when the tongue has been structurally unlocked to express its natural function — supporting more consistent, reproducible, and clinically meaningful care.
Learning Objectives
By the end of this session, participants will be able to:
- Explain how the anatomy and physiology of the tongue as a muscular hydrostat provide the foundation for assessing lingual restriction and defining the functional objective of frenotomy across ages.
- Apply a sequential, instrument-independent surgical framework incorporating tissue assessment, progressive functional release, protection of surrounding anatomy, and objective intraoperative checkpoints across awake and anesthetized care.
Evaluate release completeness using visual, functional, and measurement-based findings, including unrestricted separation of the tongue from a broad, flat floor of mouth, passive full-palate suction, and the evolving TOTRP measure.
