Although the throat is the site of the most common surgical operation in the world, it has been surprisingly free from that type of intensive physiologic investigation which, with some measure of success, has elevated nasal physiology into a position of well deserved prominence. As in the case of the nose, disturbances in the throat may be an expression of altered physiologic activity rather than the end result of gross pathologic changes. The more one examines the normal or the abnormal throat, the more firmly does this thought impress itself. The problems related to the physiology of the throat are many. The ground for painstaking investigation is rich and fertile. It requires only adequate ploughing.
The investigation I am about to describe can be characterized by a duality of approach: First, an effort has been made to determine the normal, physiologic range in the pH present in the
