The views that I have expressed in several previous publications, dating back to 1912, as to the frequency of accessory sinus diseases in children, hold at the present time with additional emphasis. Subsequent investigation of anatomic specimens and references to the work of others seems to demonstrate that the accessory nasal sinus development occurs at a much earlier period than is generally considered by most investigators, and it is accepted that their variation in size, shape and position at different ages, up to the period when they assume the adult type, is extreme.
SINUSITIS IN THE CHILD
From a careful study of the early anatomic development of the sinuses, it seems probable that many cases of meningitis are the result of unrecognized inflammation of some of the sinuses, as the symptoms of sinusitis are more or less obscure in children. That this should be so can readily be appreciated from
