Boston - Grammy Award-winner Sam Smith has undergone successful vocal cord surgery at a Boston hospital.
Massachusetts General Hospital said in a statement on Tuesday on the singer's 23rd birthday that he is expected to make a full recovery.
The surgery to stop recurrent vocal cord bleeding was performed by Dr Steven Zeitels, who has performed the same procedure on Steven Tyler, Lionel Richie and Adele.
Smith's song Stay With Me won Grammys for song and record of the year and he also was named best new artist in February.
The British's singer's In the Lonely Hour was named best pop vocal album.
According to the hospital, Smith's condition was the result of unstable blood vessels in the vocal cord that can rupture and prevent vocal performance.
Smith's next live show is scheduled for 18 July.
Despite not being able to speak or sing for three weeks, the singer was out and about visiting the Chelsea Flower Show with family and friends.
