Palatolalia

Is this palatolalia?

**Palatolalia** is a complete or partial absence of closing the lips and/or simultaneous closing of the mouth during the pronunciation of speech sounds. The cause of palatolalia may be neurological pathology. However, one of the main factors of the symptom is the presence of trismus - contraction of the masticatory muscle on one side of the jaw.

Palatolalia will have different forms depending on what form of insufficient occlusion of the oropharynx is observed in the patient. There are 2 such forms: - neorotolasia; - orotolasia. Orotolasia plays a leading role among other forms of palatolasia. The pathological condition is accompanied by unilateral or bilateral softening defect, prolapse of the soft palate, massive rhinolalia with a low-lying uvula, shortening of the soft palate, unilateral contralateral microgenia - the absence of the anterior arch of the upper palate. And here a dilemma arises: what is this “Sky”? First, let's look at the anatomical structure of the upper palate: above it is the skull, below it is the sphenoid bone, below it is the hyoid bone. Wedged between these bones, the soft palate provides conditions for the formation of a closed space called the pharyngeal space. The soft palate is an irregularly shaped formation without a certain curvature of the boundaries between the upper molars and the vestibule of the pharynx. The shape of the upper palate is determined by the shape of the base of the skull. On the hard palate, near the median suture, there is a horizontal suture, from which an unpaired rudiment of a vertical fold, the frenulum of the tongue, extends. A wedge-shaped protrusion, caused by the presence of a vertical suture, directed from the middle of the base of the brain inward and upward, ends in front of the hard palate.
