Desaults Method.—Desaultcarried a small trocar from thefistulous opening forward andinward, entering the mouth op-posite to the second molar tooth (Fig. 814).

Van Burens Method.—Van Buren cured an obstinate case by turningthe end of the duct into the mouth in the following manner: A small probewas introduced into the duct from without to steady it during dissectionand indicate its situation so as to prevent cutting it. The distal end ofthe duct was exposed for a short distance by careful dissection, and wasthen passed into the mouth through a small incision made through the632. Fig. 815.—Richelots method.
