Giant cell arteritis: diagnosed by contrast enhanced high resolution MRI

25
Q

Head face and tooth pain

A

Temporal SD TrP

26
Q

Sagittal synostosis

A

Most common synostosis
Premature sagittal suture fusion
Restricts transverse growth

Look at pic of head

27
Q

Lambdoidal synostosis unilateral

A

Flatten back of head on affected side
And compensatory growth of mastoid process on same side

Tilt in cranial base

28
Q

Positional deformational plagiocephaly

A

Ear on affected side is back and toward fused suture

29
Q

Temporal bone squamous portion

A

Zygomatic process -facial injury affects temporal bone

30
Q

Petroleum temporal bone

A

Otovestibular organ
Eustachian tube exit is between the sphenoid and temporal bones
Border or foramen lacerum (with sphenoid)
Attach of tentorium
Encloses the internal carotid
Lateral part of the jugular foramen
Styloid process

31
Q

New born temporal bones

A

No mastoid process

32
Q

Eustachian tube

A

Exits petroud portion and becomes the medial was. Of the middle ear
Internal rotation of temporalis will place pressure on Eustachian tube (high pitches tinittus)
External toyation low roaring sound or low pitch

33
Q

Internal rotation temporals

A

High pitched as place pressure on Eustachian tube

34
Q

External rotation temporal bone

A

Low roaring sound or low pitched tinnitus

35
Q

Temporal bone goes into __ ___ with SBS flexion

A

External rotation

36
Q

Describe temporal bone external rotation

A

Squamous portion moves laterally

MP moves medially

37
Q

Temporal bones moves into __ __ with SBS extension

A

Squamous portion moves medially
Zygomatic process more prominent
MP moves laterally

38
Q

Temporal bone motion is driven by the __ through the ___ articulation

A

Occiput

OM

39
Q

TMJ pain

A

Temporal bone SD

40
Q

Head pain temporal one

A

Pain along suture

OM and anterior-tension headache

Pterion-temporal headaches

Parietosquamous

41
Q

Neck pain temporal bone

A

SCM and other muscles

42
Q

Other temporal bone signed of Sd

A

Dizzy, ear infection, swelling and chewing, tinnitus, Bell’s palsy

43
Q

Swallowing and wheezing

A

TMJ, stylohyoid, styloglossus

44
Q

Tinnitus and Eustachian tube dysfunction

A

Internally rotated temporal associated with low road

Externally rotated temporal associated with high pitch

45
Q

What bones do frontal bones articulate

A

Parietal, sphenoid, ethmoid, lacrimal, maxilla, nasal, zygoma

46
Q

Axis frontal bones

A

Metopic has hinge like axis
Coronal plane motion
Moves from center of orbital roof through frontal eminence

47
Q

Motion frontal cones

A

IR ER

48
Q

ER frontal bone during SBS ___

A

Flexion

49
Q

Describe frontal bone ER

A

Lateral side moves anterior/lateral and slightly inferior, labella moves posteriorly

50
Q

Frontal bone __ happend with SBS extension

A

IR

51
Q

Describe IR frontal bone

A

Lateral side moves posterior/medial and lightly superior, labella moves anteriorly

52
Q

__ moves the frontal during external rotation

A

Sphenoid

53
Q

Head pain frontal

A

Along suture
Coronal-tension headache
Pterion-temporal headaches

54
Q

Head pain frontal

A

From diminished primary respiration and CSF flow due to increased dural tension at cribriform plate

55
Q

Organ signs of temporal SD

A

Sinusitis, visual problems (double vision), anosmia (frontal influences cribriform)
Frontalis muscle Trp/TP

56
Q

Bicoronal synostosi

A

Fusion both coronal sutures leads to bracyephaly
Causes restriction of growth of the anterior fossa resulting in a shorter and wider than normal skill

Compensatory vertical growth (turricephaly)

Seen in crouzon, Alpert sathre-

57
Q

Unicoronal synostosis

A

Premature fusion of a dingle coronal suture leads to head shape called anterior plagiocephaly.

Restricted anterior growth of skull , involving the top of the skull as well as the cranial base
This causes deformities of the face, ear, nose and forehead

Affected forehead is flat with te contralateral side move forward

Affected side ear is also more forward

Face has C shape
Facial twist

Base of noes to the affected side

Facial deformity differentiated anterior plagiocephaly from positional deformational plagiocephaly
