Adele is riding high with the runaway success of this year's biggest selling album, 21, but she's been kept off the road for much of 2011 due to vocal-cord issues. She appears to be in the process rectifying this, however, after undergoing successful vocal-cord microsurgery in Boston. Operating surgeon Dr. Steven Zeitels—who previously treated Aerosmith's Steven Tyler for a similar condition—employed special lasers to remove a benign polyp that had caused recurring hemorrhaging, or bleeding, on Adele's vocal cords. Her recovery is expected to last one or two months. [via Spin]
