Answer to Question 1

AP oblique

Rationale: The AP oblique or Grashey method is a non-trauma projection of the shoulder to demonstrate the glenoid fossa in profile. The patient is rotated toward the affected side until the coracoid process and the angle of the acromian superimpose.

Answer to Question 2

tilt and rotation

Rationale: Tilt is evident by the superior orbital rims not being superimposed. Rotation is evident by the greater wings of the sphenoid or the mandibular rami not being superimposed.
