• • When the frenulum is too short or tight, it restricts the tongue's movement.
  • The heart-shaped appearance of the tongue when attempting to lift it is a hallmark sign, caused by the frenulum pulling on the tongue's tip.
• Muscular Function:
  • The tongue's complex musculature allows for a wide range of movements essential for speech and swallowing.
  • In ankyloglossia, the restricted frenulum interferes with these movements, limiting the tongue's ability to elevate, protrude, and lateralize.

Simple Surgical Repair: Frenotomy

• Procedure:
  • A frenotomy is a simple surgical procedure to release the tight lingual frenulum.
  • In infants, it can often be performed in the clinic without anesthesia, as the frenulum has few nerve endings and blood vessels.
  • The doctor uses sterile scissors or a laser to make a small cut in the frenulum, releasing the tongue's restriction.
  • In older children or adults, local anesthesia may be used, and sutures may be required.
  • The procedure is very quick, and has a very low risk of complications.

Effects on Articulation and Resonation

• Articulation:
  • Tongue movement is crucial for producing many speech sounds, particularly those requiring tongue tip elevation (e.g., /t/, /d/, /n/, /l/, /r/, /th/, and /sh/).
  • Ankyloglossia can lead to articulation errors, such as:
    • Difficulty producing these sounds accurately.
    • Lisping.
    • Distorted speech.
  • The degree of articulation difficulty varies depending on the severity of the tongue-tie.
• Resonation:
  • While less directly affected than articulation, tongue-tie can indirectly influence resonation.
  • If the tongue's movement is severely restricted, it can affect the oral cavity's shape and size, which can slightly alter resonance.
  • Also, if the child has trouble with certain sounds, they may compensate in ways that effect resonation.
  • Difficulty with eating, can also lead to poor nutrition, which can effect overall development, including the development of the vocal tract.
• Other effects:
  • Difficulty with breast feeding in infants.
  • Difficulty with chewing, and swallowing.
  • Dental problems.

Clinical Implications

• Early diagnosis and intervention are essential to minimize the impact of ankyloglossia on speech, feeding, and oral hygiene.
• Speech-language pathologists play a vital role in assessing the condition and providing therapy after frenotomy, if needed.
• It's important to differentiate ankyloglossia from other causes of speech and feeding difficulties.
• It is also important to note, that not all tongue ties cause problems. Some people live their whole lives with a tongue tie, and never have any issues.

Sample Answer

You've described a classic presentation of a condition known as ankyloglossia, commonly referred to as "tongue-tie." Let's break down the physiology, its impact, and the simple surgical repair.

Tongue-Tie (Ankyloglossia): Physiology and Anatomy

• What's Happening:
  • Ankyloglossia is a congenital condition (present at birth) characterized by an abnormally short, thick, or tight lingual frenulum.
  • The lingual frenulum is the thin membrane that connects the underside of the tongue to the floor of the mouth.
