_Spasmodic stenosis_ may be associated with panic, or may be excited by subglottic inflammation. Prolonged wearing of an intubation tube, by disturbing the normal reciprocal equilibrium of the abductors and adductors, is one of the chief causes. The treatment for spasmodic stenosis and panic is similar. The use of a special intubation tube having a long antero-posterior lumen and a narrow neck, which form allows greater action of the musculature, has been successful in some cases. Repeated removal and replacement of the intubation tube when dyspnea requires it may prove sufficient in the milder cases. Very rarely a tracheotomy may be required; if so, it should be done low. The wearing of a tracheotomic cannula permits a restoration of the muscle balance and a subsidence of the subglottic inflammation. Corking the cannula with a slotted cork (Fig. 111) will now restore laryngeal breathing, after which the tracheotomic cannula may be removed. [PLATE V--PHOTOPROCESS REPRODUCTIONS OF THE AUTHOR'S OIL-COLOR DRAWINGS FROM LIFE--LARYNGEAL AND TRACHEAL STENOSES: 1, Indirect view, sitting position; postdiphtheric cicatricial stenosis permanently cured by endoscopic evisceration. (See Fig. 5.) 2, Indirect view, sitting position; posttyphoid cicatricial stenosis. Mucosa was very cyanotic because cannula was re-moved for laryngoscopy and bronchoscopy. Cured by laryngostomy. (See Fig. 6.) 3, Indirect view, sitting position; posttyphoid infiltrative stenosis, left arytenoid destroyed by necrosis. Cured by laryngostomy; failure to form adventitious band (Fig. 7) because of lack of arytenoid activity. 4, Indirect view, recumbent position; posttyphoid cicatricial stenosis. Cured of stenosis by endoscopic evisceration with sliding punch forceps. Anterior commissure twice afterward cleared of cicatricial tissue as in the other case shown in Fig. 15. Ultimate result shown in Fig. 8. 5, Same patient as Fig. 1; sketch made two years after decannulation and plastic. 6, Same patient as Fig. 2; sketch made four years after decannulation and plastic. 7, Same patient as Fig. 3; sketch made three years after decannulation and plastic. 8, Same patient as Fig. 4; sketch made one year after decannulation, fourteen months after clearing of the anterior commissure to form adventitious cords. 9, Direct view, recumbent patient; web postdiphtheric (?) or congenital (?). "Rough voice" since birth, but larynx never examined until stenosed after diphtheria. Web removed and larynx eviscerated with punch forceps; recurrence of stenosis (not of web). Cure by laryngostomy. This view also illustrates the true depth of the larynx which is often overlooked because of the misleading flatness of laryngeal illustrations. 10, Direct laryngoscopic view; postdiphtheric hypertrophic subglottic stenosis. Cured by galvanocauterization. 11, Direct laryngoscopic view; postdiphtheric hypertrophic supraglottic stenosis. Forceps excision; extubation one month later; still well after four years. 12,
