Trends in outpatient intervention for pediatric ankyloglossia

Anecdotally, there has been an increase in ankyloglossia referrals and frenotomy procedures performed in recent years. Many studies have characterized frenotomy indications and outcomes, but none have quantified how the frequency of referrals and interventions have changed over time in the outpatient setting. This study analyzes temporal trends in the diagnosis and intervention of ankyloglossia in a pediatric otolaryngology practice to further clarify how patterns of management of this condition have changed over time.

This study was a retrospective chart review of patients evaluated for ankyloglossia in an outpatient pediatric otolaryngology clinic between 2008 and 2018. The chi-square test for trend was used to assess yearly changes in the referral numbers, surgical interventions, and procedure indication prevalence proportions of interest.

Referral numbers and frenotomy procedures increased as a percentage of total office visits from 2008 to 2018 (P = 0.0026, P < 0.0001). The trend in frenotomies was especially pronounced in the 0 to 2-month age group (P < 0.0001) but was not observed in the 2 months to 1-year (P = 0.30) or 1- to 4-year (P = 0.40) age groups. Frenotomy performed for concerns of feeding (P < 0.0001) increased over the study period, but there was no significant increase in procedures performed for speech concerns (P = 0.13).

Significant increases in referrals for frenotomy and number of frenotomy procedures performed are demonstrated, especially in young infants for feeding concerns. It is unlikely representative of a true increase in the incidence of ankyloglossia, but rather the result of cultural and clinical factors driving referrals and intervention.
