Vocal cord nodules are primarily caused by improper pronunciation or overuse of the voice, commonly seen in people who use their voices frequently. Treatment primarily involves vocal rest, which means speaking less and pronouncing correctly. The period of vocal rest usually needs to be relatively long. If the vocal cord nodules are larger, then an even longer period of vocal rest may be required, generally lasting from two to four weeks. Clinically, most cases require four weeks. The effects are generally better after resting for four weeks. During this period, treatment can be complemented with medications, such as nebulized inhalation, which can speed up recovery. The premise is to first undergo vocal rest followed by medication treatment, which generally takes about two to four weeks.
