Formula One team Ferrari told their website on Monday that injured driver Felipe Massa had successful plastic surgery at a Sao Paulo hospital.
The operation on Massa's fractured skull lasted four and a half hours.
According to the hospital, the Brazilian driver will be released after a short stay in hospital and be at home for further rehabilitation ready for a return to racing next year.
Massa suffered the injury in July when he was hit by a spring at Hungarian Grand Prix.
Ferrari has decided to call up driver Giancarlo Fisichella to fill in Massa's seat for the last five races of this season.
