NYT Letter to the Editor 12/18/2023

Read Robyn Merkel Walsh's reply to an article in the New York Times titled "Inside the Booming Business of Cutting Babies’ Tongues". Robyn goes into great detail describing the inaccuracies in this article decrying frenectomies and tongue tie release.

Buccal Ties Paper

The buccal frenum is connective tissue that adheres the mucosa of the cheek to the alveolar process. When restricted, this condition is commonly known as a buccal- or cheek-tie. Restrictive buccal frena are often treated during tongue- and lip-tie procedures, yet widely accepted classification, diagnostic and treatment guidelines are lacking.

TalkTools® Publications by Robyn Merkel Walsh

TalkTools® was created to provide the best Oral-Placement Therapy (OPT) techniques, training, and tools to clients, therapists and parents. Our therapy techniques add a tactile component to feeding and speech therapy, enabling clients to “feel” the movements necessary for the development of speech clarity.

TOTs paper on feeding, speech and sleep

Recent studies suggest that speech, solid feeding, and sleep difficulties may be linked to restricted tongue function. Children with tongue restrictions and speech, feeding, and sleep issues underwent lingual frenectomies with a CO2 laser, paired with myofunctional exercises. Questionnaires were completed before, 1 week after, and 1 month following treatment. Thirty-seven patients participated in the study (mean age 4.2 years [range 13 months to 12 years]). Overall, speech improved in 89%, solid feeding improved in 83%, and sleep improved in 83% of patients as reported by parents. Fifty percent (8/16) of speech-delayed children said new words after the procedure (P = .008), 76% (16/21) of slow eaters ate more rapidly (P < .001), and 72% (23/32) of restless sleepers slept less restlessly (P < .001). After tongue-tie releases paired with exercises, most children experience functional improvements in speech, feeding, and sleep. Providers should screen for oral restrictions in children and refer for treatment when functions are impaired.

Oral Motor Institute

The OMI is established to publish monographs that demonstrate the evidence base of oral sensory and motor techniques for articulation, motor speech, and feeding treatment. Its mission is to contribute to the field of speech-language-hearing science by expanding our knowledge about the sensory and motor components of articulation, motor speech, and feeding development, disorders, assessment and treatment
