The 72-year-old singer "is out of surgery and doing well," his reps confirm to ET.
"His doctors report that the surgery was successful and they expect no further complications," the rep adds. " For the next 48 hours, Manilow has been instructed not to talk, sing, or rap. Barry thanks everyone for their well wishes and concern."
After undergoing surgeries on Monday and Tuesday, Manilow went to a Los Angeles-area hospital on Thursday following a performance in Memphis, Tennessee, "due to complications from emergency oral surgery" on Monday, an update on his Facebook page revealed.
Manilow's reps say he is recovering after being released from the hospital, but is unsure whether he will attend the GRAMMY Awards on Monday, where he is nominated for his 15th GRAMMY for his album, My Dream Duets, released in October 2014.
Two of the music icon's Tennessee concerts will be rescheduled.
