Correlations between different lingual frenulums and speech disorders

Abstract

Purpose: to review the literature about the different lingual frenulum alterations and correlated speech disorders. Methods: literature review about the theme was made from Medline, Lilacs and Scielo databases, from 2000 to 2010. Conclusion: according to the reviewed literature, it can be concluded that alterations on the lingual frenulum contribute to speech disorders, which have phonetic origin. There are not evidences that different frenulum alterations cause alterations in different phones. Independently from the frenulum alteration, the phones that are altered by the frenulum, in different levels are: alveolar flap, consonantal clusters and alveolar fricatives [s] and [z]
