Vocal cord polyps are a common condition in otolaryngology, with the main causes as follows: First, talking a lot. Here, talking a lot refers to normal speaking due to work or lifestyle reasons. Being in a work environment that requires extended periods of talking can lead to the development of vocal cord polyps over time. Second, improper voicing. Some people speak very hurriedly and tend to shout loudly; such habits over a prolonged period can lead to swelling of the vocal cord mucosa, which further develops into vocal cord polyps. Third, smoking. Patients who smoke heavily and for long periods can also develop vocal cord polyps, often compounded by speaking a lot while smoking, making it one of the most common causes of vocal cord polyps. Fourth, working or living in environments with significant pollution, drinking less water, and exposure to lots of dust are also common reasons.
