Vocal cord polyps cannot disappear on their own because they are a benign tumor. Without local surgical treatment, vocal cord polyps will continue to grow, causing the patient's hoarseness to worsen further. In severe cases, it can cause the patient to have breathing difficulties, leading to choking and even death. Vocal cord polyps are caused by improper use of the voice over a long period, such as yelling loudly or excessive tiredness, leading to pathological changes in the vocal cord mucosa. They can cause persistent hoarseness in patients. During an examination with an electronic laryngoscope, a smooth, light red or pale white abnormal neoplasm can be found on the anterior-middle third of one vocal cord. The vocal cord moves well, but does not close completely. In terms of treatment, patients need to undergo local surgical excision to heal. After surgery, it is important to protect the vocal cords by avoiding yelling loudly or speaking entirely, and complete recovery can generally be achieved within about a week.
