Mexican star tenor Rolando Villazon, who cancelled all his 2009 engagements after a cyst wasfound on his vocal cords, said he is already training his voice again after successful surgery.
In a note on his website, the 37-year-old singer said: "I am very happy to tell you that my surgery went very well, and that everything looks even better than we could have hoped. I have begun the re-training process, and am in very good spirits."
Villazon, who already had to take an extended break from the concert platform and opera stage in 2007 due to vocal problems, continued: "I can't wait to sing for you again."
But he appeared cautious about when that actually might be.
"It is good to have to walk a long path. One learns not to take any step for granted, or regard the sight of a flower as unimportant.
"There is no applause without a pair of hands, there is no song without two vocal cords, there is no performance without an audience... Have a great summer!"
Villazon, who shot to super-stardom alongside Russian soprano Anna Netrebko in Verdi's "La Traviata" in Salzburg in 2005, announced in April that he was cancelling all his performances this year.
Next year, he is scheduled to sing the title role in Mozart's "Idomeneo" in Paris, team up with Netrebko and Latvian mezzo Elina Garanca for Bizet's "Carmen" at the Vienna State Opera and sing the role of Des Grieux in Massenet's "Manon" in a new production in London.
Villazon is also due to star in the world premiere of a new work by Mexican composer Daniel Catan in Los Angeles in September, alongside Placido Domingo.
But it is unclear as yet whether he will be fit enough to appear in any of these performances.
