It is also noteworthy that while suppurative nasal sinusitis is relatively common, yet the incidence of orbital phlegmon is infrequent and exophthalmos is rare.

To determine the incidence of suppurative sinusitis, orbital phlegmon and exophthalmos, the available reports of the Illinois Eye and Ear Infirmary for the last ten years were examined. Three hundred and fifty-seven cases of empyema of the accessory nasal sinuses which were involved as follows were recorded: frontal, 45 per cent.; maxillary, 28 per cent.; ethmoid, 24 per cent., and sphenoid, 3 per cent.
