Medico-Chirurgical Society, and I propose to describe shortly the operative technique of what I have termed the anterior route, without touching on the various methods of intranasal operation employed by other workers, which have been incorporated in my Introduction to a recent discussion on this subject at the Royal Society of Medicine. The non-external operations for frontal sinusitis fall under two classes, (a) those restricted to the removal of ethmoid Bristol

Ingals, of Chicago, the credit is due of having devised the first practical method of operating on the frontal sinus ostium itself, i.e. of extending the operative field to the frontal sinus. Ingals reported in 1905 successful results from the operation, but it seemed to involve so much
