The singer has been unable to sing live over the past few months after undergoing emergency microsurgery on her throat to stop recurrent vocal cord haemorrhage from a benign polyp.
However, a source close to the star has revealed that doctors have given her the go-ahead to perform live again, meaning she will be able to play one of her hits at next month's show.
The insider told Radar Online: "Adele will be at the Grammys in Los Angeles on February 12 at the Staples Centre. She's thrilled to be nominated, but it's been a hard time for her because of the surgery.
"She has begun talking more, with her doctor's permission. Adele's best friend in recent weeks has been warm compresses around her neck to help the healing process of her vocal chords."
They added: "Producers of the Grammys would love to have Adele perform, and open the show, but she isn't able to give them an answer yet. She won't be able to give them an answer until the beginning of February, and they completely understand."
Adele recently beat Lady GaGa and Michael Buble to the US end-of-year chart, after selling 5.8 million copies of 21 in the States throughout 2011.
