But doctors still cautioned that his brain still has extensive bruising and did not offer predictions on whether or when they would bring him out of the induced coma.
An induced coma reduces the patient`s temperature to around 35°C (95°F) to reduce swelling of the brain.
“There are hematomes a little bit everywhere”, said Dr. Emmanual Gay, adding that surgeons decided upon a second operation after Schumacher`s condition unexpectedly improved on Monday.
Doctors refuse to say if the former racing driver was out of danger, warning that the next 24 or 48 hours of his recovery “will be decisive”.
The seven-time Formula One champion suffered a head injury following an off-piste skiing accident in the French Alps .
Schumacher fell as he skied with his 14-year-old son Mick in the Trois Vallees near the resort of Meribel on Sunday morning.
The impact was so strong that it smashed Schumacher’s helmet “in two”, yet he might not have survived the fall if he had not been wearing a helmet.
As news of the accident spread, Formula One drivers rushed to wish Schumacher a quick recovery.
Sebatian Vettel told a German news agency: “I am shocked and hope that he will get better as soon as possible”.
Fillipe Massa wrote on Instagram: “I am praying for you my brother!! I hope you have a quick recovery!! God bless you Michael”.
Jenson Button said: “Thoughts are with Michael Schumacher at this tough time. ... Michael more than anyone has the strength to pull through this”.
Schumacher is the most successful Formula One driver of all time with a record 91 total victories and 155 podium finishes in 308 Grand Prix races.
