Jakobsen underwent a five-hour operation in Sosnowiec, southern Poland, following a horrific finish-line pile-up on Wednesday evening.
Doctors on Thursday planned to bring the 24-year-old cyclist out of an induced coma, said Dr. Paweł Gruenpeter, deputy director of the hospital where Jakobsen is being treated.
The racer underwent a complicated operation overnight involving anaesthesiologists, oral surgeons and ear, nose and throat specialists, state news agency PAP reported.
Three other riders who suffered lesser injuries in the pile-up were also being treated in hospitals, doctors said.
Jakobsen crashed into a barrier while battling for victory with countryman Dylan Groenewegen during the first stage of the Tour de Pologne.
He was resuscitated at the scene in Katowice, southern Poland, and airlifted to a hospital. Officials said at the time that he was battling for his life.

Groenewegen, meanwhile, was disqualified for causing the incident, public broadcaster Polish Radio’s IAR news agency reported.
Poland’s largest cycling race started on Wednesday amid the coronavirus pandemic, attracting more than 150 riders from various countries.
The first leg of the annual event saw them cover a 195.8 km route starting in the city of Chorzów and ending in Katowice in Poland’s southern Silesia region.
Last year's Tour de Pologne was marred by the death of Belgian cyclist Bjorg Lambrecht who sustained serious injuries in an accident.
The 22-year-old hit a concrete culvert by the road during the third stage of the race from Chorzów to Zabrze in the south of Poland on August 5, 2019.
