Abstract:
So-called "primary" or "infantile" forms of deglutition, also termed lingual dyspraxia, are treated in different ways by orthodontists using various appliances to correct the condition and are also managed by speech-therapists and physiotherapists. The results obtained are often unstable. We have developed a more holistic approach to this disorder by attempting to grasp the underlying mechanisms in order to achieve more satisfactory correction. By establishing normal salivary deglutition more rapidly, this manual osteopathic technique complements the methods which use voluntary rehabilitation to impress upon the body's physical reflexes the "motor image" of the act to be accomplished. In order to render this article more lively and accessible, we have chosen to let the tongue speak in the first person--which, after all, is only normal!
