Laryngeal cancer usually develops in people aged 50 to 70 years old, especially in men who smoke and drink heavily. Due to its special location, obvious pre-symptoms and slow metastasis, most patients can still be operated even if they have neck metastasis when diagnosed, so most patients have the chance to recover from radical treatment and cure. For patients, the most important thing is to choose the most suitable treatment for themselves according to their different conditions. Recovery depends on early detection and treatment Many people take hoarseness of voice lightly, but in fact it may be a precursor of laryngeal cancer and should seek medical consultation immediately to avoid delaying the disease. people over 50 years old, or even 40 years old, who are frequent smokers and drinkers, should seek medical consultation immediately if they have hoarseness of voice for two weeks or more for no reason. Although throat discomfort, foreign body sensation or dry cough are relatively common symptoms of throat discomfort, they are not unique to laryngeal cancer. However, once you experience the above symptoms, you must go to the ear, nose and throat department of a regular hospital to rule out the possibility of laryngeal cancer. In terms of laryngeal cancer treatment, surgery is still the main treatment in China, supplemented by radiotherapy and chemotherapy. According to the early and late development of tumor, i.e. the stage of tumor, the scope of tumor and the patient’s physical condition, there are mainly 15 methods of surgical techniques mastered by the surgeon in charge: 1. laser resection of laryngeal cancer or supraglottic cancer under laryngoscope; 2. laryngeal laceration vocal cord resection; 3. vertical hemilaryngeal resection cartilaginous muscle flap repair; 4. Vertical frontal resection of the larynx; 5. Vertical lateral anterior subtotal resection of the larynx; 6. Vertical lateral anterior partial laryngectomy of the epiglottis (Tuker procedure); 7. Partial laryngectomy of the neck; 8. Partial laryngectomy of the neck; 8. Partial laryngectomy of the neck; 9. Horizontal hemilaryngectomy; 10. Middle laryngectomy of the crico-lingual epiglottis anastomosis; 11. Middle tracheal arch 12.Circumferential laryngeal anastomosis; 13.Proximal total laryngectomy (Pearson procedure); 14.Total laryngectomy; 15.Total laryngectomy with simultaneous articulatory tube implantation; The surgeon has to choose the best surgical method according to the patient’s above conditions. If laryngeal cancer can be detected early, the cancerous tissue can be partially removed to achieve the purpose of minimally invasive treatment, preserving good laryngeal function without radiotherapy and reducing the pain suffered by patients, so that the 5-year survival rate of early laryngeal cancer can reach 90%. For mid- to late-stage laryngeal cancers, as long as there is no distant metastasis, most patients can still be cured through surgery and comprehensive treatment, or prolong their lives.
