[Dimorphism of cerumen, facts and theory].
¿Dimorphism¿ means the existence of two phenotypic different types of the human cerumen and morphology of the cerumen glands. In this paper, the morphological, biochemical, and functional differences are reviewed. The wet cerumen is better adapted to a hot and humid climate where infections of the outer ear are very frequent and sometimes severe. In a cold and dry climate, the dry cerumen is advantageous. In the moderate climates, both types are equivalent (balanced dimorphism).
