Which LAYER does CP result from?
|
CP results from a disturbance to the MESODERM (middle layer):
The middle layer gives rise to: muscle, connective tissue, bone & cartilage, blood vessels |
|
When does CL form?
|
Results when there is a failure in union/merging of the MAXILLARY& NASOMEDIAL processes
|
|
When does CP form?
|
Results from the failure in midline union of PALATAL SHELVES
|
|
Normal VPC mechanism
|
Is a sphincteric valving operation esstial to normal speech, whistling, blowing, swallowing, and sucking
|
|
Normal VPC mechanism for speech
|
VPC requires upward & backward movement of soft palate, along with medial movement of lateral pharyngeal walls and posterior pharyngeal walls.
- It separates the nasal and oral cavities |
|
Uvulus Muscle
|
- BIG Contributor in VP closure
- The only INTRINSIC Muscle of the soft palate Attachments: Has A-P orientation; Anteriorly attaches from palatine aponeurosis (two separate bundles run parallel to each other and course posteriorly thru velum superficial to levator) Inserts: Into the uvula near the tip Action: Bulges the middle third of dorsal (upper) surface of the velum, making the major contribution to Levator Eminence |
|
What are the muscles that contribute to VPC for speech?
|
1. Levator Veli Palatini
2. Uvulus 3. Superior constrictor 4. Palatopharyngeus |
|
Superior Constrictor
Attachments/actions |
- Has lesser contributions in VPC than the other muscles
Attachments: From behind- attaches to median ralphe of pharynx; runs forward/anteriorly in pharyngeal wall and most superior fibers enter velum; attaches anteriorly to hamulus of medial pterygoid plate, pterygomandibular raphe; has lesser attachments to lingual base & mandibular alveolus Actions: Responsible for medial movements of lateral pharyngeal walls & forward movements of posterior pharyngeal wall which take place at level of palatal plane (or below palatal plane for swallowing) |
|
Levator Veli Palatini
|
Attachments: From the ptrous portion of temporal bone, courses downward and medially passing below and lateral eustachian tube opening and torus tubarius to enter the middle third of velum where it meets its partner from the other side
Actions: Elevates & retracts the velum; makes some contribution to levator eminence |
|
Palatopharyngeus
|
Attachments: Attaches from lateral pharyngeal walls at the level of thyroid cartilage and courses up
Inserts: Into posterior third of velum on each side Actions: May contribute to narrowing VP port; May be responsible for medial movement of lateral pharyngeal walls; **Participates in lowering velum |
|
At what age do you have the CL repaired? CP repaired?
|
CL- 10-12 weeks
CP- 9-12 weeks |
|
Children with CP universally suffer from what?
|
Chronic Middle Ear Dysfunction - PE tubes are typically inserted at the time of lip repair and/or initial repair
|
|
What are sources of early speech sound MISLEARNING in CP?
|
1. Deficient Velopharyngeal Valve - therefore VPC is not possible
2. Absent/structurally aberrant bony partition (causes sensorimotor mislearning) 3. Hearing loss 2' to middle ear effusion |
|
Submucous Cleft Palate signs?
|
1. Bifid uvula
2. Midline Diastema/pale zone of the palate 3. Palpable notch |
|
What are some possible causes of VP Inadequacy?
|
- SMCP
- Occult SMCP - Palatopharyngeal Disproportion - Mechanical Interference/obstruction to adequate VP closure (tonsils, adenoids, faucial pillars) - Inadequate movement of velum - Velopharyngeal mislearning |
|
What are some types of Velopharyngeal Incompetency? (non-cleft)
|
1. Primary Motor/Neuromotor Control (Dysarthria, Cerebral Palsy, TBI, CVA, progressive disease)
2. Motor Association/Motor Programming (Arpaxia) |
|
What are some types of Velopharyngeal Mislearning? (non-cleft)
|
1. Phonemic-Specific Nasal Emission (selective HPCs)
2. Persisting Post-op Nasal 3.Compensatory Misarticulations 4. Deafness/Hearing Impaired |
|
What are some types of Velopharyngeal Insufficiency? (non-cleft)
|
1. Mechanical Interference (tonsils, adenoids, posterior pillar web)
2. Palatopharungeal Disportion (cervical anomalies, flattened cranial base) 3. Ablative palatal lesions (cancer, traumatic injury) |
|
What some causes of VP inadequacy with clefts?
|
1. Unrepaired palatal clefts (overt, submucous, Occult submucous)
2. Post-surgical Insufficiency (post-palatal closure, Post-adenoidectomy, Post-pharyngeal flap, Complicated fistula) |
|
What does intermittent Hypernasality suggest?
|
- Marginal/sporadic closure ability
or - Phonemic Specific Nasal Emission |
|
What does continuous/pervasive Hypernasality suggest?
|
- Physically based VP problem
|
|
What does hyponasality or cul-de-sac in connected speech on nasal consonants, vowels, and sonorants suggests?
|
- Large Adenoids
or - Obstructive Pharyngeal Flap or - Intranasal airway obstruction |
|
What does consistent Nasal Emission on all pressure consonants suggests?
|
Structural:
- Unoperated cleft - Inadequately Repaired Cleft or Non-structural: - Neurogenic |
|
What does inconsistent Nasal Emission suggests?
|
Fistula
or PSNE |
|
What does weak oral pressure suggests?
|
- Physically based VP closure pattern
|
|
What is always seen with pt w/ NE and continuous HN?
|
Weak Oral Pressures
|
