Can Sinusitis Become Serious?

While it is quite uncommon, sinusitis can become serious, especially in children. If left untreated, an infection that has spread to the eye can cause blindness. Spread of the infection into the brain can result in serious diseases such as meningitis.

Fortunately, with the modern antibiotic treatments available, such spread of infection is very rare.
