Study summary

Conservative estimates show that 3-5% of all infants have tongue tie. These studies only focus on visible, anterior tongue tie. Deeper, more visibly subtle cases of ankyloglossia have not been included in these incidence numbers, so the percentage of children with ankyloglossia is much higher than previously thought. Previous research by the investigators demonstrates that posterior tongue tie can be as problematic as anterior ties.

An available FDA-approved feeding solution allows for the measurement of infant sucking motions. This allows for detection of changes following surgical intervention. Previous ultrasound studies show the importance of the upward movement of the tongue, but further lingual movement parameters following frenotomy have not been reported.

The primary goal of this study is to record changes in lingual movement following lingual frenotomy. The investigators plan to compare improvements over time between a control, non-intervention group and a frenotomy group. Secondary goals include recording validated outcomes of reflux and feeding efficiency.

    Surgical group

    Procedure: Lingual frenotomy

  • No intervention
    Observation group

Interventions

  • ProcedureLingual frenotomy

    A lingual frenotomy will be performed using a CO2 laser - using the NFANT bottle feeding system, the intervention arm will be compared against the observation arm to determine if there are changes in lingual mobility parameters during bottle feeding.

What researchers measure

Primary outcomes

  1. Improved sucking parameter on the NFANT bottle feeding system - amplitude

    The NFANT bottle feeding system automatically generates measurements of sucking parameters. The first sucking parameter to be measured is calibrated nipple movement (amplitude)

    Time frame: 10 days

  2. Improved sucking parameter on the NFANT bottle feeding system - sucking frequency

    The NFANT bottle feeding system automatically generates measurements of sucking parameters. The second sucking parameter to be measured is sucking frequency.

    Time frame: 10 days

  3. Improved sucking parameter on the NFANT bottle feeding system - sucking duration

    The NFANT bottle feeding system automatically generates measurements of sucking parameters. The second sucking parameter to be measured is sucking duration.

    Time frame: 10 days

  4. Improved sucking parameter on the NFANT bottle feeding system - sucking smoothness

    The NFANT bottle feeding system automatically generates measurements of sucking parameters. The second sucking parameter to be measured is sucking smoothness.

    Time frame: 10 days

Secondary outcomes

  1. Measurement of infant reflux

    Use of a validated survey (the infant gastroesophageal reflux questionnaire revised or I-GERQ-R questionnaire). The I-GERQ-R utilizes ordinal response scales to measure the severity of symptoms associated with infant gas- troesophageal reflux disease (GERD). Scoring involves the sum- marization of 12 items (score range, 0-42), where lower scores reflect lower symptom severity.

    Time frame: 10 days

  2. Measurement of feeding efficiency

    Feeding efficiency can be measured (volume of intake over measured time)

    Time frame: 10 days

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 14, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
