Three dimensions on the undersurface of the tongue were measured on 50 children ranging from 1 month to 5 years of age. All measurements were obtained while the children were in a state of light anesthesia. General growth trends were summarized in grouped data by sublingual dimensions and by total length from the mandible to the tip of the tongue.
A consistent change over age was found for all measurements. The findings are discussed with regard to identification of ankyloglossia, or tongue-tie, through quantitative evaluation. Case studies are included to illustrate the value of these data in clinical decisions regarding frenectomy.
