Comments:

This is acknowledged to be a bundled term but retained here because of its usefulness in practice. Ear length is determined by the maximal distance from the superior aspect to the inferior aspect of the external ear. Normal values are available from birth to 16 years of age [Feingold and Bossert, [1974]; Hall et al., [2007]] and birth to 18 years of age [Farkas, [1981]] specific for sex. If only length is increased the term Long ear should be used. Normal values for ear width are available [Farkas, [1981]].
