The heightened incidence of disturbances of the upper respiratory tract during the active period of teething is a commonplace and widely recognized phenomenon. The child who acquires a husky voice, a croupy cough, persistent rhinitis and earache at the time when a tooth is about to erupt generally has no febrile disturbance except when there is present some focus of chronic infection which becomes exacerbated. The clearing up of these symptoms follows so promptly after the eruption of the tooth as to make it obvious that the disturbance is of a reflex nature.
The feature of this teething disturbance that is often most disconcerting is the otalgia, which is associated with marked injection and reddening of the tympanic membrane and of the adjacent wall of the external auditory canal and with retraction of the ear drum. Myringotomies have often been performed needlessly in cases of this kind in the past,
