The surgery fixed a nasal problem that the Czech rider has had since receiving a blow a few days before the 2011 marathon Worlds, in which he finished second.
Kulhavy, who is still making up his mind about whether to race on the road or off-road next year, is expected to resume training within a few days.
In recent days, Olympic gold medal winner Kulhavy was also recognized as an "honorary citizen" of Ústí nad Orlicí in the Czech Republic according to pardubice.idnes.cz.
