In doing submucous resections of the nasal septum, I have many times felt the need of a combined dissector and suction cannula. The only instrument of this type on the market, as far as I have been able to find, is one devised by Dr. Walker of Springfield, Mass. I have found this dissector to be too large and the dissecting point too short to be an ideal instrument in submucous work.
After a few years, the average specialist in this line has usually become accustomed to a certain type of dissector, more often Freer's than any other. The new dissector which I am offering is much the same size and shape as Freer's single point elevator, except that the dissecting blade is a little narrower and the curve a little flatter than those in Freer's instrument.
The new dissector is simple in construction, being made of hollow tubular steel
