Ankyloglossia and Tethered Oral Tissue: An Evidence-Based Review

Tongue and Mandibular Disorders of the Pediatric Patient

Robin sequence, macroglossia, and ankyloglossia are disorders affecting the tongue and mandible in the pediatric population. Each of these can have a significant impact on breathing, feeding, speech, dentition, and craniofacial growth. This review discusses the interdependent and coordinated development of both the tongue and mandible, the functional impacts of these disorders, and appropriate management strategies.

Ankyloglossia as a Barrier to Breastfeeding: A Literature Review

This is a literature review of ankyloglossia and its correlation with lactation problems. Ankyloglossia, commonly referred to as tongue-tie, brings about functional difficulties and, in some cases, may lead to early weaning. It is crucial to use breastfeeding as the exclusive food source for the first six months of an infant's life, and the interference of the tongue contributes substantially to success in this regard. Even though there are many publications about ankyloglossia, there are still many controversies about its definition, diagnosis, classification, and treatment decision determined via frenotomy. Some researchers state that the identification of ankyloglossia should be based on morphological and anatomical evidence, while others claim that a short or tight frenulum should be examined in correlation with the impact on the mother-infant dyad during breastfeeding. By encouraging and supporting mothers in coping with feeding difficulties, their lactation experiences are improved, and they can continue breastfeeding.

Ankyloglossia: Typical Characteristics, Effects on Function, and Clinical Implications

The purpose of this article is to (1) define the diagnostic characteristics of ankyloglossia, (2) identify potential problems associated with ankyloglossia, and (3) discuss treatment options, when treatment is appropriate. This article is based on a review of the literature, including recent systematic reviews, and the author's experience as a cleft and orofacial specialist. Ankyloglossia is a common congenital condition characterized by an anterior attachment of the lingual frenulum on the tongue. This causes difficulty elevating and/or protruding the tongue tip. As such, ankyloglossia has been thought to affect neonatal feeding, speech, and other functions. Although systematic reviews have concluded that most infants with ankyloglossia can be fed normally, a small percentage of affected infants will show improved efficiency of feeding post-frenotomy. They also concluded that frenotomy may relieve nipple pain in the breastfeeding mothers of affected infants. Regarding speech, the systematic reviews concluded that there is no evidence that ankyloglossia causes speech disorders. This may be because simple compensations will result in normal acoustics of the sounds. Therefore, frenotomy should be recommended sparingly for newborn infants, and it should rarely, if ever, be recommended for speech disorders.

Tethered Oral Tissue Release Among Breastfed Infants: Maternal Sources of Information and Treatment

BACKGROUND

Despite limited clinical consensus regarding surgery for tethered oral tissues ("tongue-tie") for resolving breastfeeding-related issues, the procedure has been increasing in the United States. Greater understanding of maternal experiences with obtaining surgical release may help to improve breastfeeding outcomes.

RESEARCH AIM

To explore experiences of breastfeeding mothers with infants having undergone "tongue-tie" surgery.

METHOD

This online, cross-sectional, observational survey occurred between August and September 2020. Eligibility included being ≥ 18 years of age and previously or currently breastfeeding an infant with ≥ 1 tissue surgically released. Of 463 screens, 318 mothers were eligible and 115 consented. The final sample was 90.

RESULTS

The sample was predominantly white (n = 86; 95%), non-Hispanic (n = 84; 93%), married/cohabitating (n = 85; 94%), and currently providing their own milk (n = 81; 89%).Difficult latch was the primary reason for seeking help. Participants reported lingual (n = 84; 93%), labial (n = 79; 88%), and buccal (n = 16; 17%) tissue-release, with 80% (n = 73) reporting > 1 released. For each tissue released, > 80% (n = 72) of participants felt "very confident" in their ability to correctly identify it and 97% (n = 87) felt "very involved" and "strongly agreed" with surgical release. International Board Certified Lactation Consultants^® were the most frequently identified source of information (n = 45; 50%) and referrals (n = 38; 42%), while pediatric dentists most frequently performed interventions (n = 60; 67%).

CONCLUSIONS

Participants reported being confident, involved, and in agreement with surgical release and lactation support professionals were frequent information and referral sources.
