The pus accumulates between the cartilage and the layer

Physical examination of the ear
Ears should be inspected for size symmetry, shape and position.
Superior portion of the ear must be level with the outer canthus of the eye.
Inflammation should not be there and the skin of the ear must be smooth.
Inspection of the external ear canal can be done by direct observation.
Patient must be asked to tilt their head to the opposite side while the nurse pulls the pinna up and backwards.
Penlight torch can be used to inspect of excessive wax, swelling, redness, scaliness, drainage or foreign bodies.
