A cleft lip is an opening of the upper lip, mainly due to the failure of fusion of the medial nasal processes with the palatal processes; a cleft palate is the opening of the soft and hard palate in the mouth, which is due to the failure of the palatal shelves to fuse together. [10]
A high-arched palate (also termed high-vaulted palate) is where the palate is unusually high and narrow. It is usually a congenital developmental feature that results from the failure of the palatal shelves to fuse correctly in development, the same phenomenon that leads to cleft palate . [ 1 ]
Sometimes poorly constructed prosthetic teeth may be the cause if the original bite is altered. Usually, the teeth are placed too far facially (i.e., buccally and/or labially), outside the " neutral zone ", which is the term for the area where the dental arch is usually situated, where lateral forces between the tongue and cheek musculature are ...
While identifying the causes of tongue thrust, it is important to remember that the resting posture of the tongue, jaw, and lips are crucial to the normal development of the mouth and its structures. If the tongue rests against the upper front teeth, the teeth may protrude forward, and adverse tongue pressure can restrict the development of the ...
Children with Möbius syndrome may have delayed speech because of paralysis of muscles that move the lips, soft palate and tongue root. However, with speech therapy, most people with Möbius syndrome can develop understandable speech. [5] Möbius syndrome has been associated with increased occurrence of the symptoms of autism. [6]
flaccid paralysis, [1] such as soft palate weakness (examined by asking the patient to say aah). [1] muscle atrophy, [1] such as tongue atrophy with fasciculations. nasal speech lacking in modulation and difficulty with all consonants. drooling of saliva. [1] normal or absent jaw jerk. reduced or absent gag reflex. [1]
Maxillary hypoplasia is the most common secondary deformity that results from cleft lip and cleft palate. Because of the subjective nature of the diagnosis, the incidence of maxillary hypoplasia in people with cleft lip and palate varies between 15-50%. It is estimated that 25-50% of these patients require surgical intervention. [7]
The condition most commonly is located at the junction of the hard and soft palate. [1] However, the condition may arise anywhere minor salivary glands are located. [nb 1] It has also been occasionally reported to involve the major salivary glands. [2] [3] It may be present only on one side, or both sides. [1] The lesion typically is 1–4 cm ...
