Abstract
INTRODUCTION: It has been proposed that ankyloglossia and lingual frenotomy have increased. The aim of this study was to analyse the trends of ankyloglossia and lingual frenotomy among children treated in hospitals in Denmark in the 1996-2015 period.
METHODS: We included children aged 0-17 years registered with the diagnosis ankyloglossia (DQ381) or the procedure frenotomy (KEJC20) using nationwide hospital-based data from the Danish National Patient Registry in 1996-2015. The incidence during the study period and the average annual percentage change (AAPC) and age-specific incidences were calculated.
RESULTS: A total of 1,608 children were diagnosed with ankyloglossia (67% boys). The overall incidence of ankyloglossia increased from 3.2 per 100,000 in 1996 to 13.6 per 100,000 in 2015, corresponding to an AAPC of 7.1%. The age-specific incidence revealed a more than ten times higher incidence of ankyloglossia among patients less than one year old compared with those aged one year or above. In all, 3,625 frenotomy procedures were carried out (66% boys). The frequency of frenotomy increased from 5.1 per 100,000 in 1996 to 38.5 per 100,000 in 2015, corresponding to an AAPC of 11.1%. The age-specific incidence of frenotomy showed a more than thirty times higher frequency among children less than one year of age.
CONCLUSIONS: Ankyloglossia and frenotomy increased significantly during the period 1996-2015 among children in Denmark according to nationwide hospital data. Rates of both ankyloglossia and frenotomy were highest in children less than one year of age and among boys.
