The medical bulletin issued Monday by the San Raffaele hospital in Milan confirmed that Berlusconi suffered a broken nose and two broken teeth. It said Berlusconi is taking antibiotics and painkillers as the pain is "persistent."
Doctor Alberto Zangrillo said surgery will not be necessary. He said that Berlusconi will remain hospitalized at least until Tuesday.
Berlusconi was hit by a man hurling a statuette at him as he was signing autographs at the Milan rally. The 73-year-old leader was taken to hospital with blood under his nose, on his mouth and under one eye.
The 42-year-old man accused of attacking Berlusconi as he signed autographs in Milan was immediately taken into custody.
The attack occurred at a time when Berlusconi, one of Italy's wealthiest men, is embroiled in, a divorce case with his wife and public protests demanding his resignation.
TV showed the stunned leader with blood under his nose, on his mouth and under one eye as he was lifted to his feet by aides after Sunday's attack. He was hustled into the back of a car, but he immediately got out, apparently to show he was not badly injured.
Berlusconi was basking in the aftermath of a rousing speech and signing autographs when the man hit him the mouth with a miniature statue of the Milan cathedral.
The attack was the latest in a string of protests. Last weekend tens of thousands marched in Rome to demand Berlusconi resign. He has been accused of massive conflicts of interest and of tailoring laws to protect him from prosecution in cases involving his media, real estate and sports empire, CBS News correspondent Allen Pizzey reports. He has even been.
In what some Italians see as gloss on his image and others as a disgrace, various sex scandals involving call girls and wild parties have been splashed across the Italian and international media. Berlusconi's wife, a former actress, is suing him for divorce over what she called his infatuation with young women.
Police identified the man they were questioning as Massimo Tartaglia, 42. They said Tartaglia didn't have any criminal record but had suffered psychological problems in the past.
Pizzey reports that the suspect was punched and verbally assailed by Berlusconi fans before being arrested.
