The partial or complete obliteration of the frontal sinus cavity by osteogenesis is, I believe, a hitherto undescribed complication of chronic disease of the frontal sinus.
A chronic infection of the mucosa may spread into the bony walls of the sinus and terminate in osteomyelitis, or osteogenesis, if I may use the latter term to indicate a disease rather than an entity. In osteomyelitis, which is a destructive osteitis, the tissues are overwhelmed and destroyed by the invading organisms, as so notably described by Wilensky,1 Dan McKenzie,2 Furstenberg,3 Mosher4 and others,5 whereas in osteogenesis, which is a proliferative osteitis, the tissues become proligerous to wall off or encapsulate the infecting organisms.

So far as the bone changes are concerned, the pathological condition is directly related to the normal processes of bone growth in the nose, in its origin, and throughout its
