Lecture 5: Developmental Deficits Flashcards
What are some Anomalies?
Dental ENT Language Cognition Psychosocial
What makes up Normal Dentition?
Deciduous/Primary – - 20 teeth (10 maxillary arch, 10 mandibular arch) - by 29 mos. Permanent – - 32 teeth (16 each arch) - from ~7yrs-20yrs
Types of occlusions/malocclusions
- Class I occlusion – normal upper overlap
- Class I malocclusion – incorrect line (teeth don’t match, are rotated, etc.)
- Class II malocclusion – overbite
- Class III malocclusion – underbite
What are dental anomalies with clefts?
Missing teeth – primary cleft palate>lisp
Supernumerary teeth – extra teeth>alveolars, interdentals, lateral lisp
Ectopic teeth – erupt in abnormal position>alveolars, interdentals, lateral lisp
Rotated teeth – primary cleft palate>lateral lisp
Crowding – lateral lisp, frontal lisp
Crossbite – cleft lip & palate>sound distortions, frontal lisp, lateral lisp
Class III malocclusion
Open bite – from missing teeth, finger/pacifier sucking, skeletal deformities>frontal lisp of fricatives, affricates; lateral lisp of sibilants
Protruding premaxilla – B cleft lip & palate>distortion of sibilants, sub labiodentals for bilabials
What are some speech problems?
Misarticulation/distortion of sibilants (/s/, /z/, /sh/, /ch/, /j/), labiodentals (/f/, /v/), alveolars (/t/, /d/, /l/, /n/), bilabials (/p/, /b/, /m/)
Labioversion - Overjet=horizontal overlap of incisors (norm 2mm)
- Lip closure probs
- Bilabial sound distortion
Linguoversion – underjet=upper incisors lingual to lowers
- Distorts sibilants and alveolars
Teeth crowding/narrow maxillary arch/macroglossia
- Lateral lisp – if opening is in line with cleft (air flows around)
- Frontal lisp – if maxillary central incisors missing
ENT anomalies include:
Ear Nose Face Oral Cavity Throat/upper airway
Ear anomalies include:
Microtia – small, deformed pinna>conductive hearing loss
Aural atresia – abnormal EAM & tympanic membrane>conductive hearing loss
Abnormal ossicle formation/fusion>conductive hearing loss
Otitis media – malfunction of E-tube> tympanic membrane rupture, conductive hearing loss
Otic capsule abnormal development/ossification >sensorineural hearing loss
Nose anomalies include:
External deformities
- Facial cleft
Abnormalities of nasal base
- Cleft lip
- Cleft palate
Internal derangement
- Deviated septum (cleft palate)>hyponasality, cul-de-sac resonance
- Septum deflects into cleft side of nose
- Pyriform aperture stenosis=narrowed nares from overgrown maxilla
- Choanal stenosis/atresia=narrowed/blocked choanae>cholic, death
Face anomalies include:
Maxilla
Facial nerve
oral cavity anomalies include:
Lips Mouth Tongue Palate Tonsils & adenoids
Throat/upper airway anomalies include:
Adenotonsillar/Adenoid/Tonsillar hypertrophy
What are language deficits that occur?
Developmental factors
- IQ and brain structure-rate of acquisition of all dev’tl milestones
- No difference in cleft and normal
- Cleft palate + syndrome are at risk
- Environmental stimulation-dev’t of lang skills in language-rich environment under age of 5
- No difference in cleft and normal
- Hearing-perception>acquisition of oral lang skills
- Cleft palate-high risk chronic otitis media
- Motivation-need & desire to learn skill; “motivation to talk”
- Cleft tend to revert to gestures b/c difficulty with speech production
- Attention-attend to environment
- ADHD in 3-5% of children; most carniofacial syndromes + neuro at risk
- A & P-vocal tract, processes (respiration, phonation, resonance, artic), neuro fxn
Language development in cleft
Language dev’t & learning - Early deficits in cognitive dev’t - Prelanguage skills - Lower expressive language - Common in syndromes Phonological/Articulation dev’t - Disrupted tactile-kinesthetic-auditory feedback loop - Less vocalization - Predominant nasals for orals; glottals for plosives - Habitual compensatory productions - Age of palate repair is factor - Apraxia co-occurrence is factor
What are psychosocial aspects of cleft?
Family issues
School issues
Society issues
Family issues include:
- Initial shock & adjustment
- Cleft as chronic medical condition
