Otitis Media: The Case for Human Evolution in its Pathogenesis

Renowned pediatric otolaryngologist Dr. Charles Bluestone discusses the impact of evolution on the increased incidence of otitis media in infants and children.

Educational Objectives:

Upon completion of this activity, participants should be able to:

  • Provide evidence that as a consequence of adaptation for bipedalism humans are born at nine months gestation whereas birth should be after 21 months which contributes to the pathogenesis of otitis media in the first year of life.
  • Provide evidence that as a consequence of adaptation for speech as well as facial flattening in humans the pharynx and larynx anatomy changed compared with our immediate ancestors
  • Provide support for the hypothesis that as a consequence of facial flattening and adaptation for speech in humans, as compared with our immediate ancestors, the palatal muscles related to Eustachian tube function changed and may be related to the relatively high incidence of otitis media in humans as compared with other species in nature.
