人到老年后,机体各器官功能都会衰退,发音器官——喉也是一样,如果不注意保护嗓子,发音过多、过劳,会出现声音嘶哑,形成哑喉咙。声音嘶哑是嗓音疾病的常见症状,一般来说,由喉部的急性炎症,喉结核,声带肿物如息肉、小结、喉部的良恶性肿瘤及精神、神经等因素引起。值得警惕的是声音嘶哑有时成为肺部、食道及纵隔等处肿瘤的早期信号。由于这些部位的肿瘤压迫喉返神经,而喉返神经是运动神经,受到压迫便造成声音嘶哑,因此50岁以上的老年人,持续声音嘶哑超过1个月以上者,应提高警惕并及时检查。
When people reach old age, the functions of various organs of the body will decline. The organs of pronunciation and the throat are the same. If you do not pay attention to protecting your throat, pronouncing too much or overworking, you will have a hoarse voice and a dumb throat. Hoarse voice is a common symptom of vocal diseases. In general, it is caused by acute inflammation of the larynx, larynx tuberculosis, vocal cord masses such as polyps, nodules, benign and malignant tumors of the larynx, and nerves. It is worth noting that hoarseness sometimes becomes an early sign of tumors in the lungs, esophagus and mediastinum. Because these parts of the tumor compress the recurrent laryngeal nerve, while the recurrent laryngeal nerve is a motor nerve, oppressed will cause hoarseness, so over the age of 50 elderly people with persistent hoarseness more than 1 month, should be vigilant and promptly checked.
