Minimally invasive surgery for epiglottis cysts usually does not affect the vocal cords, but complications during anesthesia cannot be ruled out. Epiglottis cysts are a common throat condition that may be associated with prolonged consumption of spicy and irritating foods and inflammatory infections, which can cause discomfort such as foreign body sensation and obstruction in the throat. As minimally invasive epiglottis cyst surgery requires epiglottis cyst removal under support laryngoscope, the surgery is incision-free. The surgical site is not in the same anatomical region as the vocal cords and is separated by the epiglottis cartilage, so there is no effect on the vocal cords. Before the surgery, the cartilage and joints related to the vocal folds may be affected due to anesthesia operation, and symptoms of hoarseness may occur. If hoarseness occurs after the surgery, it should be reflected to the surgeon in time for timely and targeted treatment.
