external rotation
sagittal articulation moves inferiorly
temporal articulation moves laterally
cranium widens laterally

Head Pain - tension headaches
temporal headaches
head, face, and tooth pain
MMA

Question 15

Sagittal Synostosis

Answer 15

most common form of synostosis
premature fusion of the sagittal suture
increased A and P growth

Question 16

Lambdoid synostosis

Answer 16

most commonly mistaken for posterior positional deformational plagiocephaly
results in flattening of the back fo the head of the affected side and ipsilateral compensatory growth of the mastoid
leads to characteristic tilt in the cranial base
ear on affected side of deviated posteriorly

Answer 28

external rotation - lateral side moves anterior/lateral and slightly inferior, glabella moves posteriorly internal rotation - lateral side moves posterior/medial and slightly superior, glabella moves anteriorly

Question 29

frontal bone external rotation

Answer 29

sphenoid moves the frontal during external rotation lateral side moves anterior/lateral and slightly inferior glabella moves posteriorly

Question 30

frontal bone internal rotation

Answer 30

lateral side moves posterior/medial and slightly superior | glabella moves anteriorly

Answer 31

``` focal head pain - coronal global head pain frontalis muscle sinusitis visual problems anosmia ```

Question 32

Bicoronal synostosis

Answer 32

restriction of growth of the anterior fossa results in a shorter and wider shape - brachycephaly compensatory vertical growth - turricephaly associated with syndromes liek Apert, Crouzon, Muenke, and Pfeiffer

leads to a head shape called anterior plagiocephaly face has a characteristic C-shape or facial twist base of nose is drawn towards the affected side affected forehead is flat and contralateral more anterior
