A vocal cord granuloma is a benign growth that forms on the vocal cords due to irritation or trauma from vocal use or acid reflux. It causes hoarseness, voice breaks, and a sensation of something in the throat. Treatment involves controlling acid reflux through diet, medication, and voice therapy to address harmful vocal behaviors. Surgery is usually a last resort as granulomas often resolve with proper medical management and lifestyle changes to avoid further irritation and trauma to the vocal cords.
