I recently posted a question about Sleep Apnea?

My boyfriend was sent by his job to get tested for sleep apnea. I forgot to mention that when he was in his early 20's he was in a fight, and had is nose broken. One of his nasal passages is narrower than the other, and when he snores, a loud sound comes from the narrower nostril. Could his snoring be because of this, and not sleep apnea? I know that he doesn't stop breathing while he sleeps. Could it possibly be a deviated septum?
