The advantages of a dry field in surgery have long been appreciated by every surgeon. This is particularly desirable in nasal surgery. We usually rely on the production of partial hemostasis by the injection of anesthetic agents containing epinephrine and on the use of suction apparatus. In submucous resections particularly, it is important to separate the septal mucosa with its attached perichondrium and periosteum from the cartilaginous and bony septum by the use of a periosteal elevator such as the types designed by Freer, Joseph, McKenty, etc. This mucoperichondrial and mucoperiosteal dissection demands a dry field. Inasmuch as the area available is very limited, it is often difficult for an assistant to apply suction to the field while the operator manipulates both the nasal speculum and the periosteal elevator. Very often an assistant is not available and the operator must complete the dissection by himself. This he can do by
