"Mr. President underwent an operation for the treatment of his ear ailment over the weekend and stayed in the hospital for a night. Mr. President is in good health and continues his studies at the Istanbul Tarabya Mansion," a statement from his office said.
Gul had the same surgery at Ankara's Hacettepe University Hospital in August 2012 and for the first time in 2006 at the Gulhane Military Academy of Medicine in Ankara, Today's Zaman reported.
His doctor advised him not to fly too often because the problem could recur.
As minister of foreign affairs and later as president, Gul has had to cancel visits to Israel, Iraq, Iran, Russia, Italy, Palestine and Kazakhstan due to his ongoing ear problem, the nature of which was not specified.
