Mount Sinai West head and neck surgeon Mark Urken said the procedure went well, in a statement released by the hospital on Friday.
Kelly’s wife, Jill, said her husband is experiencing some swelling and added: “Everything is moving forward as planned.”
The procedure involved doctors adding tissue into the upper portion of his mouth. Kelly is scheduled to have permanent dentures inserted during a follow-up procedure in September.
Kelly has been unable to eat solid foods since March, when he had surgery to have cancer removed from his jaw after tests revealed a recurrence. The 58-year-old Kelly was initially diagnosed five years ago with oral cancer, and had been cancer free since September 2014.
