Laryngeal cancer refers to malignant tumor originating in the larynx. Symptoms include hoarseness, sore throat, foreign body sensation in the throat, blood in sputum, difficulty in breathing, lymph node metastasis in the neck, etc. If the above symptoms occur, you should go to ENT department for fiberoptic laryngoscopy and other examinations as soon as possible, and pathology should be taken for clear diagnosis if abnormalities are found. Most of the external causes of laryngeal cancer are related to smoking, alcohol consumption, air pollution and viral infection, etc. Currently, laryngeal cancer is mainly treated by surgery and radiation therapy. Since larynx has important physiological functions such as pronunciation, breathing and swallowing, in addition to the lesion itself, doctors should make a personalized treatment plan for the patient by taking into account the patient’s age, work nature, economic status, physical quality and other factors, which is extremely important for the future life of a laryngeal cancer patient. The advantages of surgical treatment are not only the immediate removal of the tumor, but also the preservation of important functions of the larynx such as articulation, breathing and swallowing, which requires precise localization of the size of the cancer and “tailor-made” resection and reconstruction. For early stage laryngeal cancer cases, our KTP laser-supported laryngoscopic laryngectomy is the first in China to achieve minimally invasive treatment of laryngeal cancer with minimal trauma and good efficacy and hospitalization time of only two to three days. For mid-stage laryngeal cancer cases, according to the size of the cancer site, we can use the corresponding procedures such as laryngeal laryngectomy, frontal partial laryngectomy, vertical hemilaryngectomy, middle laryngectomy, supraglottic horizontal laryngectomy and subtotal laryngectomy to restore the healthy life of patients in about ten days. For advanced laryngeal cancer, although total laryngectomy deprives patients of their laryngeal cavity, articulation reconstruction surgery, mechanical larynx and electronic larynx can also restore the function of articulation and communication for patients without larynx. The biggest advantage of radiotherapy is that the function of laryngeal structure is well preserved without surgery, but the disadvantage is that the treatment period is long, and symptoms such as skin radiotherapy injury, loss of taste and smell, dry mouth and difficulty in swallowing may occur.
