Ankyloglossia, commonly referred to as a tongue-tie, is a congenital condition where the lingual frenulum, the thin band of tissue beneath the tongue, is unusually short or tight. This restriction limits the tongue’s range of motion, often interfering with feeding or speech function. To correct this, a frenotomy or frenulectomy procedure is performed to release the tight tissue. A primary concern following this procedure is the possibility of reattachment, or recurrence, which causes the original symptoms to return.
Understanding Why Reattachment Occurs
Recurrence is not the original tongue-tie growing back, but rather a complication of the body’s natural wound healing process. Following the release, an open wound is created on the floor of the mouth that must heal via secondary intention. This healing involves the formation of granulation tissue, which appears as a white or yellowish patch beneath the tongue.
The body’s goal during healing is to close the wound, and if two raw surfaces remain in close proximity, they can fuse together prematurely. This process, known as wound contraction, causes the edges of the incision to pull together horizontally instead of healing vertically. Insufficient aftercare, specifically a lack of consistent post-operative stretching exercises, is the most common reason the healing edges prematurely reattach and tighten.
Functional Signs of Recurrence
The most telling indication of reattachment is the return of functional difficulties that had initially improved after the procedure. In infants, this manifests as a loss of effective oral motor skills necessary for feeding. Parents may notice the baby is once again clicking or making smacking sounds while nursing, signaling a breakdown of the suction seal.
The breastfeeding parent may experience a return of nipple pain, described as a pinching or compression sensation, and may find the nipple is creased or flattened after a feed. For the infant, poor milk transfer can lead to frustration, short or excessively long feeding sessions, and failure to gain weight appropriately. These difficulties are often accompanied by increased gassiness or reflux-like symptoms due to swallowing excessive air during inefficient feeding.
For older children who had the release to improve speech or eating, recurrence is signaled by a renewed difficulty with oral function. They might struggle with chewing and managing food in the mouth, or show signs of discomfort such as increased fussiness or tension in the head and neck muscles.
Signs in Older Children
- Difficulty with certain sounds, such as /l/, /r/, or /t/, which require precise tongue elevation.
- Struggling with chewing and managing food in the mouth.
- Messy eating, gagging, or difficulty sweeping food debris from the teeth.
- Increased fussiness or tension in the head and neck muscles, suggesting restricted tongue movement.
Physical Assessment for Reattachment at Home
Caregivers can perform a simple visual and tactile check at home, distinct from the daily aftercare stretches, to assess the healing site. A complete release should result in a diamond-shaped wound where the tissue was divided, which should remain open and pliable as it heals. Gently lift the tongue toward the roof of the mouth and observe the wound site using a flashlight.
A healthy healing site displays the initial diamond shape, often filled with white or yellow granulation tissue. If the diamond shape appears to be shrinking significantly, becoming muddled, or forming a thick, horizontal band, it suggests the wound edges have reattached.
To assess mobility, lift the tongue gently to its maximum point of elevation and observe the tissue underneath. If reattachment has occurred, the tissue will feel taut, restricting the upward lift of the tongue and creating noticeable tension in the floor of the mouth. The tongue should be able to elevate easily toward the palate without excessive force.
Professional Evaluation and Treatment Options
If a recurrence is suspected, professional evaluation is the necessary next step. Specialists who perform revisions, such as pediatric dentists, otolaryngologists (ENTs), or trained International Board Certified Lactation Consultants (IBCLCs), can provide a definitive diagnosis. They often use specialized assessment instruments, such as the Hazelbaker Assessment Tool for Lingual Frenulum Function (HATLFF), to objectively score the appearance and functional mobility of the tongue.
The HATLFF assesses both the physical characteristics of the frenulum and the tongue’s functional movement, providing a quantitative measure of restriction. If a significant reattachment is confirmed, a revision procedure, often called a refrenotomy or refrenulectomy, may be recommended. This procedure is typically performed using scissors, a scalpel, or a laser, depending on the provider’s training and patient age.
Following a revision, a comprehensive post-operative protocol, often involving myofunctional therapy, is necessary to prevent a second recurrence. This includes specific stretching exercises designed to guide the wound to heal vertically. Adherence to this aftercare ensures the long-term maintenance of the tongue’s newly gained range of motion and a successful functional outcome.
