lecture Qs final Flashcards
torticollis
abnormal twisting of the neck which causes the head to be held in a rotated or tiltled position
75% right side
muscular causes of torticollis
fibromatosis colli
muscle spasm following trauma
just trauma
cause of torticollis(broad)
Muscular or Skeletal
cause of torticollis skeletal
unilateral interfacetal dislocation UID occipital condyle fracture Atlanto -axial rotatory fixation cns related subarachnoid hemorage
Fibromatosis colli
rare but accounts for 80% of childhood torticollis
due to traumatic delivery &
positioning in utero- develops 2-3wks after birth
benign proliferation of fibous tissue into SCM lower 1/3
Bezold’s abscees
complication of suppurative mastoiditis
Occurs when infection errodes the mastoid tip into the neck, forming an abscess — can result in torticollis*
true or false
torticollis can be caused by Rheumatoid Arthritis
true
due to Pannus
most common sagittal synostosis
doliochocephaly (sagittal synosis
sagittal synostosis
Boat head/ scaphoscephaly(broad term 4 sagital)
used to describe a narrow head shape
Coronal synostosis unilateral
Bent-Head( Plagiocephaly)
More on left
if coronal synostosis bilateral
brachycephaly
metopic synostosis
triangle -head ( trigonocephaly)
lamboid synostosis
slant head- Occipital plagiocephaly
scaphocephaly
most common form of craniosynostosis; more common in males
premature closure of sagittal suture
Trigonocephaly
premature closure of metopic suture
turricephaly
premature closure of coronal suture
Frontal plagiocephaly
2nd most common craniosynostosis
Occipital Plagiocephaly
More common in immobile children
premature closure of lamboid suture on one side
syndromic craniosynostosis
autosomal dominant linked to chromosome 10q
FGFR
(fibroblast growth factors)important in angiogenis
related to craniosynostosis syndromes
binds to many receptors
will see too much bone formation
FGFR1
pfieffer syndrome
FGFR2
HOTTEST fibroblast gene for mutations:(learn 1 &3 easier) crouzon syndrome Apert Syndrome Prieffer syndrome Jackson wies syndrom
FGFR3
Achondroplasia
thanstophoric dysplasia
primary craniosynotosis
abnormal biology of the suture causes premature suture closure- FGfR related craniosynotosis
secondary craniosynotosis
suture biology is normal
but abnormal external forces result in premature suture closure
crouzon sydrome
craniofacial dysostosis complete penetrance autosomal dominant 50%due to spontaneous mutations Due to mutation of FGFR-2gene =10q26* NO SYNDACTYLY or cervical fusion
class 3 , midface hypoplasia
apert
autosomal dominant
FGFR2- gene 10q26
Pfeiffer’s syndrome
skull is prematurely fused and unable to grow normally -craniosynostosis
Bulging wide set eyes due to shallow eyesockets
FGFR-2
under developed mid face
Muenke syndrom
phenmotypic overlap occurs with other disease
intellect normal
Characterized by coronal synostosis or macrocephaly
jackson wiess syndrom
foot abnormalities and premature fusion of certain parts of the skull
ventrolateral
early migration trunk neural crest cell..
they migrate into and through the anterior of half of each somite
vagal and sacral neural crest generate what
parasympathetic(enteric) ganglion
Cardiac neural crest cells form
Endothelial lining
where does heart form
ink neck under pharyngeal arches
cranial(cephalic) neural crest cells
cells from craniotomy facial mesenchyme ;
creates facial cartilage and bone
neuro plate folds and forms
neural tube
poor saliva affects which arch more
Mandibular
poor saliva causes
more friction at the denture mucosa interface
