Vocal cord polyp is initially treated by conservative management with voice rest and voice therapy. If it doesn't improve then the surgery done is microlaryngeal surgery. It is done under general anesthesia
. It is a quick and safe procedure done in about 20-30 mins. If done properly and with care by a trained ENT specialist
your voice should be back to normal. After the surgery you will be given voice rest and therapy. The tissue will generally be sent for testing to determine the nature of the polyp, if its benign then there isnt anything further that is needed.
I hope you found my response to be helpful and informative. If you have any additional concerns I would be happy to address them.
