The Impact of Ankyloglossia Beyond Breastfeeding: A Scoping Review of Potential Symptoms.

OBJECTIVE: The purpose of this study was to evaluate the spectrum of pediatric quality-of-life sequelae associated with ankyloglossia that may affect children who do not undergo tongue-tie release (frenotomy) during infancy. DATA SOURCES: This study contains data from PubMed, Embase, CINAHL, PsycINFO, Web of Science, and Google Scholar (1961-January 2023). REVIEW METHOD: The review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews reporting guidelines. Experimental and observational studies were eligible if they reported baseline outcomes associated with ankyloglossia in children above a year of age. Two reviewers independently screened studies, extracted data, and assessed quality. Low-quality studies were excluded. CONCLUSIONS: Twenty-six of 1,568 screened studies (> 1,228 patients) were included. Six studies were high quality and 20 were medium quality. Studies identified various symptoms that may be partially attributable to ankyloglossia after infancy, including speech/articulation difficulties, eating difficulties, dysphagia, sleep-disordered breathing symptoms, dental malocclusion, and social embarrassment such as oral hygiene issues. Multiple comparative studies found associations between ankyloglossia and risk factors for obstructive sleep apnea; a randomized controlled trial found that frenotomy may attenuate apnea severity. Ankyloglossia may also promote dental crowding. IMPLICATIONS FOR PRACTICE: Ankyloglossia may be associated with myriad effects on children's quality of life that extend beyond breastfeeding, but current data regarding the impact are inconclusive. This review provides a map of symptoms that providers may want to evaluate as we continue to debate the decision to proceed with frenotomy or nonsurgical therapies in children with ankyloglossia. A continuing need exists for controlled efficacy research on frenotomy for symptoms in older children and on possible longitudinal benefits of early frenotomy for maxillofacial development.
