"We expect a full recovery," said Dr. Martin Cooper, chief of neurosurgery at Cedars-Sinai Medical Center and Taylor's lead surgeon. "The tumor appears to be benign," the doctor said, adding that a biopsy will be performed to make sure.
Taylor will spend at least 24 hours in intensive care and will remain hospitalized about a week, the doctor said.
Led by Dr. Cooper, a four-doctor team removed the growth in the lining of the brain behind her left ear. They used a 3-D computer image of the tumor to assist their surgery.
The operation began shortly after 9:15 a.m. PT Thursday and lasted about four hours. Dr. Cooper said the procedure went smoothly without any complications.
The two-time Oscar winner was in good spirits before being wheeled into the operating room at Cedars-Sinai Medical Center in Los Angeles, her spokeswoman said. Taylor's four children--Michael Wilding, Christopher Wilding, Liza Todd-Tivey and Maria Burton-Carson--and nine of her grandchildren have been at her bedside since she entered the hospital.
In 1994, Dr. Cooper treated George Burns after the comedian suffered head injuries in a 1994 bathroom fall.
Taylor learned of the tumor after an MRI brain scan during her annual physical exam on February 3.
The actress checked into Cedars-Sinai on Tuesday in preparation for the surgery, two days after Hollywood turned out to celebrate her 65th birthday. Taylor officially turns 65 on February 27.
