Question

Quizplus · Accepted Answer

If a sinus infection spreads beyond the sinuses and into the surrounding areas, it can potentially spread to the brain through the blood vessels or the bony structures of the skull. This can lead to serious and potentially life-threatening conditions such as meningitis and brain abscesses. However, it is important to note that such complications are rare and typically only occur in severe or untreated cases of sinus infections.
