IV: Structural Communication and Swallowing Disorders Flashcards
(165 cards)
craniofacial
outer nasal structures (4)
nasal bridge, columella (supports nasal tip), ala nasi (curved part around nostril), naris
craniofacial
nasal septum (6)
divides the nasal cavity into two sections, includes: vomer bone, perpendicular plate of the ethmoid, quadrangular cartilage, turbinates/conchae (divided into superior, middle and inferior), meatus (also divided into superior, middle and inferior)
craniofacial
upper lip (4)
philtrum, cupid’s bow, labial tubercle, vermillion (red lip tissue)
craniofacial
tongue (2)
dorsum of tongue (dorsal/top surface) :: ventrum of tongue (ventral/under surface)
craniofacial
faucial pillars and tonsils (4)
anterior/posterior faucial pillars, palatine tonsils, lingual tonsils
craniofacial
bones of the oral cavity (5)
alveolar ridge, incisive foramen, pre maxilla, hard palate, pterygoid process of the sphenoid bone
craniofacial
velar structures (3)
velum/soft palate, median palatine raphe, uvula
craniofacial
pharyngeal structures (3)
pharynx (oropharynx, nasopharynx, hypopharynx, posterior pharyngeal wall, lateral pharyngeal walls), adenoids/pharyngeal tonsils (removal can affect velopharyngeal function), eustachian tube (connects middle ear to pharynx, responsible for middle ear function)
craniofacial
properties related to velopharyngeal function (3)
knee action (bending to provide maximum contact with the posterior pharyngeal wall), velar dimple (formed by contraction of the levator muscles), passavant’s ridge (shelf-like projection from the posterior pharyngeal wall)
craniofacial
pharyngeal wall movement (2)
lateral:to close against velum :: posterior:assists in achieving contact against the velum
craniofacial
muscles of the velopharyngeal valve (1)*
velopharyngeal sphincter (levator veli palatini, superior constrictors, palatopharyngeus, palatoglossus, salpingopharyngeus, musculus uvulae, tensor veli palatini)
*all muscles are paired on each side of midline
craniofacial
innervation of velopharyngeal complex (6)
pharyngeal plexus (network of nerves that lies along the posterior pharyngeal wall), involvement of cranial nerves: V, VII, IX, X, IIX
craniofacial
variations in velopharyngeal closure (3)
coronal (most common, complete closure with little contribution from lateral pharyngeal walls), circular (second most common, complete true-sphincter closure), sagittal (complete closure due to lateral movement medially)
craniofacial
primary palate structures (3)
those located anterior to the incisive foramen, includes lip and alveolar ridge, develops at 7 weeks gestation, embryological path from the incisive foramen to the lip
craniofacial
primary palate clefts (2)*
complete clefts of the primary palate:extend through the lip and alveolus to incisive foramen :: incomplete clefts:do not extend all the way to the incisive foramen and can include: forms frustrating (slight lip notch), cleft of the lip only, or cleft of the lip and just part of the alveolus
*can be unilateral or bilateral where incisive sutures are primarily affected
craniofacial
secondary palate structures (4)
located posterior to incisive foramen, develops at 9 weeks gestation, embryological path from the incisive foramen to the uvula, includes: hard palate, velum, uvula
craniofacial
secondary palate clefts (2)
complete clefts of the secondary palate:extend from the uvula to the incisive foramen :: incomplete clefts:do not extend all the way to the incisive foramen and can include: bifid uvula, cleft of the velum only, or cleft of the velum and just part of the hard palate
craniofacial
effects of cleft lip and palate on speech (3)
dental and occlusal anomalies (cross bites, class III malocclusions), hearing loss due to eustachian tube malfunction, velopharyngeal insufficiency (VPI)
craniofacial
effects of cleft lip and palate on feeding (2)
cleft lip:usually does not affect feeding :: cleft palate:inability to build up suction/compress nipple (thus, breastfeeding is not possible)
craniofacial
pierre robin sequence (5)
a wide bell-shaped cleft palate, micrognathia (small mandible), glossoptosis (posterior tongue position), airway and feeding difficulties, speech issues secondary to velopharyngeal insufficiency (VPI)
craniofacial
velocardiofacial syndrome (5)
deletion 22q11.2 syndrome, usually occult submucous cleft palate or velopharyngeal hypotonia, velopharyngeal dysfunction causing hyper nasality, cardiac and vascular anomalies, facial anomalies (microcephaly, micrognathia, nasal)
craniofacial
stickler syndrome (5)
cleft palate only, pierre robin sequence, wide flat face, sensorineural hearing loss, risk for velopharyngeal insufficiency
craniofacial
FAS (5)
fetal alcohol syndrome, pierre robin sequence, cleft palate and cleft lip, short nose and flat philtrum and thin upper lip, developmental disabilities with behavioral problems
craniofacial
trisomy 13 (4)
cleft lip and palate with possible midline cleft, eye defects, midline facial deformities, fatal before first birthday
