Assessment of Posterior Tongue Mobility Using Lingual-Palatal Suction: Progress Towards a Functional Definition of Ankyloglossia
January 2021 | Journal of Oral Rehabilitation
A functional definition of ankyloglossia has been based on assessment of tongue mobility using the tongue range of motion ratio (TRMR) with the tongue‐tip extended towards the incisive papilla (TIP). Whereas this measurement has been helpful in assessing for variations in the mobility of the anterior one‐third of the tongue (tongue tip and apex), it may be insufficient to adequately assess the mobility of the posterior two‐thirds body of the tongue. A commonly used modification is to assess TRMR while the tongue is held in suction against the roof of the mouth in lingual palatal suction (LPS).
