Ultimate-Guitar.com reports that DISTURBED vocalist David Draiman has had surgery to repair his stomach and lungs for an acid reflux problem, and now he's set for another operation. Draiman has had a rough time trying to keep his voice in shape for Ozzfest, but with some vocal exercises and proper rest and nutrition he's counteracting the drying out of his vocal cords. The vocalist said that a deviated septum caused by three broken noses forces him to breath through his mouth, drying out his vocal cords.

"I'm actually going in for surgery after this is done," Draiman said. "I have to correct a deviated septum. It's called a septoplasty. My nose has been broken three times, so I've got all kinds of broken cartilage and shrapnel and stuff in there. Most people's septums are straight, mine is kind of like an 'S'."

Draiman added that it's not exactly a pretty operation.

"Well, they need to cut a piece here, lift up the whole flap of my nose, cut out the septum, and they tell me that the scar tissue portion will grow back, and they're taking out all the broken pieces," he said. "So my nose is going to look a little different after the whole procedure is done, but this is something that will hopefully enable me to breathe a lot better. It's been one of the factors in what continues to happen with my voice. I don't sleep properly, and I will breathe through my mouth and dry out my vocal chords every single night, and the whole next day I'm trying to repair the damage. It's just a vicious cycle. So I'm just trying to eliminate all the X-factors that are involved and do everything I can so that I can maintain."

Draiman hopes to heal in time so the band can make up dates missed in Europe for their upcoming tour, which is slated to kick off September 14 in Munich, Germany.
