Chaiwan Charoenchoketavee, director of Vajira Hospital, said an operation to remove bullet shrapnel from Mr Sondhi's head was successful.
Mr Sondhi would have to remain in the hospital's intensive care unit for about a week while he recovers.
"The operation is completed. It took about two hours and Mr Sondhi is now safe, in a good condition and able to talk," Dr Chaiwan told a news conference.
"The bullet shrapnel penetrated the outer skull and caused the broken skull to crush the outer membrane of the brain, but it did not penetrate into the brain itself," he said.
The wound was more serious because of his age.
Police said the gunmen, riding in a pickup, fired about 100 rounds from assault rifles through the windows of Mr Sondhi's car as he was on the way to moderate his regular programme at the studios of the satellite TV station, ASTV, about 5am on Friday.
"At least two attackers followed Mr Sondhi's car, overtook it and sprayed it with about 100 rounds of gunfire from AK-47 and M-16s,'' Pol Col King Kwaengwisatchaicharn said.
