The diagnosis of laryngeal disease in young children, impossible with the mirror, has been made easy and precise by the development of direct laryngoscopy. No anesthetic, local or general, should be used, for the practised endoscopist can complete the examination within a minute of time and without pain to the patient. The technic for doing this should be acquired by every laryngologist. Anesthesia is absolutely contraindicated because of the possibility of the presence of diphtheria, and especially because of the dyspnea so frequently present in laryngeal disease. To attempt general anesthesia in a dyspneic case is to invite disaster (see Tracheotomy). It is to be remembered that coughing and straining produce an engorgement of the laryngeal mucosa, so that the first glance should include an estimation of the color of the mucosa, which, as a result of the engorgement, deepens with the prolongation of the direct laryngoscopy. _Chronic subglottic edema_, often the result of perichondritis, may require linear cauterization at various times, to reduce its bulk, after the underlying cause has been removed. _Perichondritis and abscess_, and their sequelae are to be treated on the accepted surgical precepts. They may be due to trauma, lues, tuberculosis, enteric fever, pneumonia, influenza, etc. _Tuberculosis of the larynx_ calls for conservatism in the application of surgery. Ulceration limited to the epiglottis may justify amputation of the projecting portion or excision of only the ulcerated area. In either case, rapid healing may be expected, and relief from the odynphagia is sometimes prompt. Amputation of the epiglottis is, however, not to be done if ulceration in other portions of the larynx coexist. The removal of tuberculomata is sometimes indicated, and the excision of limited ulcerative lesions situated elsewhere than on the epiglottis may be curative. These measures as well as the galvanocautery are easily executed by the facile operator; but their advisability should always be considered from a conservative viewpoint. They are rarely justifiable until after months of absolute silence and a general antituberculous regime have failed of benefit. _Galvanopuncture_ for laryngeal tuberculosis has yielded excellent results in reducing the large pyriform edematous swellings of the aryepiglottic folds when ulceration has not yet developed. Deep punctures at nearly a white heat, made perpendicular to the surface, are best. Care must be exercised not to injure the cricoarytenoid joint. Fungating ulcerations may in some cases be made to cicatrize by superficial cauterization. Excessive reactions sometimes follow, so that a light application should be made at the first treatment.
