Measurement of infant tongue thickness using ultrasound: A technical note

Novel uses of ultrasound include obtaining images of intra‐oral structures to further research in speech production and feeding. In this technical note we describe a noninvasive, cost‐effective, and reliable method for measuring infant tongue muscle thickness. The current pilot study demonstrates high reliability of a trained ultrasonographer to obtain adequate images of the infant tongue and the ability to measure reliably between two anatomic landmarks to determine tongue thickness and investigate a potential relationship between tongue size and tongue force. © 2012 Wiley Periodicals, Inc.
