Ear, Protruding

Definition:

Objective: Angle formed by the plane of the ear and the mastoid bone greater than the 97th centile for age OR Outer edge of the helix more than 2 cm from the mastoid at the point of maximum distance

Comments:

Normal values are available [Farkas, [1981]; Hall et al., [2007]]. In mild cases the superior crus of the antihelix is deficient; in more severe cases the lack of normal folding may be more extensive, but these should be recorded separately. Ears that are protruding may give the appearance of increased size, but this should be assessed separately.

Synonyms:

• Ear, Prominent

Replaces:

• Ear, Bat
