Abstract:
We have analysed bony defects of the hard palate in patients with submucous cleft palate to find out whether velopharyngeal insufficiency (VPI) is dependent on the extent of these defects. We evaluated the maxillofacial structures associated with cleft palate by 3-dimensional computed tomography (CT) in 23 children diagnosed with submucous cleft palate. Bony defects of the hard palate were divided into Type I, defined as absent posterior nasal spine (n=12), Type II, V-shaped bony notch (moderate, n=7), and Type III, as bony defect extending into the incisive foramen (severe, n=4) defects, respectively. VPI was found in 10, 3, and 4 patients, respectively. Neither VPI nor the degree of bifid uvula was significantly associated with the types of bony defects.

Oral Cavity
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
