Diseases of the throat and nasal passages; a guide to the diagnosis and treatment of affections of the pharynx, sophagus, trachea, larynx, and nares . ofa special canulated laryngeal director, through which the AFFECTIONS OF THE LARYNX AND TRACHEA. string is passed, and which is removed as soon as the bougiehas been secured in the grasp of the forceps. These bougiesare allowed to remain night and day until removal is necessaryto cleanse them, or it becomes advisable to replace them withlarger ones. The forceps is withdrawn when the bougie is tobe removed, and it is then extracted by means of the string,which has been secured externally. More recently the bougiehas been secured in place by means of a special inner canula,which is short, and provided superiorly with a rod or staff,which passes through a perforation in the lower portion of thebougie, which projects through the fenestrum of the outercanula. The inner canula is secured to the outer one by abayonet-catch. Hollow bougies have been suggested, to facili-tate respiration in the direction of the normal channel, duringthe treatment. In order to render the dilatation more rapid,. Fig. 184.—Mackenzies dilator for laryngeal stenosis. Schroetter and others have devised special mechanical dilators(Fig. 184), the action of which is controlled by a screw move-ment externally, which is likewise adjusted to a gauge, whichindicates the amount of dilatation secured at the other dilator is retained in position for a short time, and thenreplaced by a bougie of corresponding calibre, which is securedin the canula. These dilators are by no means well borne, andit is still uncertain whether they really hasten the cure. When the dilatation is complete, the external wound isclosed, and retraction prevented by the retention daily, forfrom fifteen to thirty minutes, of curved tubes of hard-rubber,the laryngeal portion of which has the same shape as the tinbougies, and the horizontal portion protruding from the mouthis fu
