In considering the prognosis of tubercular laryngitis it is my desire to do so under three heads:
1. In regard to local lesions.
2. In regard to restoration of function.
3. In regard to life.
Irrespective of the character of the local lesions it is impossible to give an abstract prognosis concerning them.
Most careful consideration must be given the pulmonary and general condition of the patient. With extensive and rapidly breaking down pulmonary areas the the reparative process in the larynx may be nil, as it is in other parts of the body. With slight pulmonary involvement, general condition good, the prognosis is more favorable. Laryngeal manifestations seldom improve under any treatment unless the pulmonary and general conditions improve.
With increased activity of the pulmonary disease, further infection of the larynx is likely to occur through the lymphatics and vessels or by direct infection of the bacilli in the sputum;
