[Significance of sudden infant death (SIDS) for otorhinolaryngology].

The high frequency of proven extensive infection in the upper respiratory tract, particularly the nose and pharynx, of infants with SIDS, suggests that the latter may be due to upper airway obstruction. In view of the particular vulnerability of the early infant, the widespread term "common cold" does not seem justified. The constant incidence of SIDS should stimulate study of the extension and effects of infection of the upper respiratory tract, including careful investigation, follow up and adequate therapy by otolaryngologists. Such a concept may prevent unexpected fatal complications.
