Ranbir, who turned 32 Sep 28, was admitted to the Breach Candy Hospital here.
"He was hospitalised...and he got discharged today morning. It was just a minor surgery, nothing serious," an official from the facility, told IANS.
If a report is to be believed, the adenoid tonsil had been troubling Ranbir for a while, due to which he had to sometimes sleep with his mouth open to ease breathing.
The actor was last seen on the big screen in "Besharam".
