Laryngeal papilloma

Introduction to laryngeal papilloma Papilloma is a common benign tumor of the larynx, which may be related to human papillomavirus infection. It is easy to relapse after surgery, easy to malignant, and patients with malignant transformation are more common in middle-aged patients. In children with laryngeal papillomas associated with viral infections and chronic irritation, there is a tendency to stop growing spontaneously after puberty. Juvenile laryngeal papilloma is more common than 6 months to 5 years after birth. It often occurs in many parts of the laryngeal mucosa. It is multiple, often hyperplasia of the glottic region with the glottis as the center, and rarely malignant changes. Young laryngeal papilloma has a natural regression after puberty. Adults usually develop after the age of 20, with an average age of about 50 years, often single, often located on the underside of the vocal cords. The squamous epithelium of the nipple is markedly keratinized, and can be cancerous (about 2-3%), which is considered as a precancerous lesion. Treatment is usually treated with surgery or laser medicine. basic knowledge The proportion of illness: 0.008% Susceptible people: no specific population Mode of infection: non-infectious Complications: difficulty swallowing
