The 45-year-old star, who has been suffering from Trigeminal Neuralgia, a nerve disorder that causes intense pain in the face, had left for the US on August 29.
"The surgery was done last night and lasted for five hours. It will take at least fifteen days for him to resume work and he is advised complete rest till then. Fresh tests will be conducted further to check the progress of recovery. After that he will then go to South Africa to shoot for Ek Tha Tiger," sources close to the actor told PTI.
The 'Dabangg' actor developed the nerve disorder in his jaw in 2007 while shooting for 'Partner'. It became worse last year following which he decided to undergo a surgery.
