32 DISEASES OF THE LARYNX 



Pathology.— Chronic catarrh leads to hyperemia of the 

 parts with hypertrophy of the mucosa and the submucosa, 

 together with fibrous tissue proliferation. Localized thick- 

 enings, either flat or wart-like, are often noticed. The sub- 

 mucosa is infiltrated with cells and the mucous glands are 

 swollen and distinct, producing a granular condition. 



Symptoms.— The symptoms are somewhat similar to those 

 of acute laryngitis but not so severe and continue for a longer 

 time. The cough is hoarse, dry, seldom moist, and is aggra- 

 vated by exposure to cold, exercise or excitement. The 

 larynx is less sensitive than in the acute form when examined 

 by external manipulation. After severe attacks of coughing 

 the patients may show nausea and vomiting. 



Diagnosis.— The chronic course, absence of general symp- 

 toms and the cough characterize the condition. 



Prognosis.— Owing to the changes in the mucosa and the 

 submucosa, improvement is slow and complete recovery 

 seldom takes place. 



Treatment.— Hygienic— Keep warm; supply plenty of 

 fresh air. 



Dietetic.— Give warm liquid foods (milk, soups, etc.). 



Medical.— The following formulae may be used to stop the 

 coughing and allay the irritation :
