The hard palate is formed by the palatine process of the maxilla and horizontal plate of palatine bone.It forms a partition between the nasal passages and the mouth.On the anterior portion of the hard palate are the plicae, irregular ridges in the mucous membrane that help hold food while the teeth are biting into it while also facilitating the movement of food backward towards the larynx once ...
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 ]
OMD in adult and geriatric populations are due to various neurological impairments, oral hygiene, altered functioning of muscles due to aging, systemic diseases, etc. Tongue thrusting is a type of orofacial myofunctional disorder, which is defined as habitual resting or thrusting the tongue forward and/or sideways against or between the teeth ...
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]
Submucous cleft palate can also occur, which is a cleft of the soft palate with a split uvula, a furrow along the midline of the soft palate, and a notch in the back margin of the hard palate. [12] The diagnosis of submucous cleft palate often occurs late in children as a result of the nature of the cleft. [13]
Furthermore, if a cleft patient has lip pits, he or she has a ten times greater risk of having a child with cleft lip with or without cleft palate than a cleft patient who does not have lip pits. [4] Types of clefting between parents and affected children are significantly associated; however, different types of clefts may occur horizontally ...
Pierre Robin sequence [a] (/ p j ɛər r ɔː ˈ b æ̃ /; [3] abbreviated PRS) is a congenital defect observed in humans which is characterized by facial abnormalities.The three main features are micrognathia (abnormally small mandible), which causes glossoptosis (downwardly displaced or retracted tongue), which in turn causes breathing problems due to obstruction of the upper airway.
To check the uvula, a tongue blade is pressed down on the patient's tongue and the patient is asked to say "ah"; the uvula should look like a pendant in the midline and rise along the soft palate. Abnormal findings include deviation of the uvula from the midline, an asymmetrical rise of the soft palate or uvula and redness of either.
