The use of the low pressure chamber in relieving sinusitis was first reported by Andrews, Roth and Ivy in 1940.1 They studied the effects of reduced atmospheric pressure in 16 cases of advanced sinus disease and noted subjective relief of symptoms in 14 cases. The patients reported a marked increase in drainage, with diminution of pain, pressure and nasal congestion. In that preliminary report a simple nontraumatic method of promoting drainage and aeration of sinuses was presented and its possible application as a practical therapeutic measure in cases of sinus disease was suggested. The principle was first used by Behnke2 in 1932; he used slow compression followed by rapid decompression in the high pressure chamber.
In the past two years the decompression method has been used by us in the treatment of a series of 125 patients with subacute and chronic sinusitis, and the effects on the progress of their
