(HealthDay News) — Sinusitis occurs when the air-filled cavities inside the skull become inflamed.
The University of Maryland Medical Center says these factors increase your child’s risk of developing sinusitis:
- Having hay fever or allergic rhinitis (a stuffy or runny nose often accompanied by itchy eyes and post-nasal drip).
- Being in daycare.
- Having a condition that affects the cilia (small hairs in the sinuses).
- Undergoing altitude changes, such as those that occur during air travel or scuba diving.
- Having enlarged adenoids, or rarely, an infected tooth.
- Having a immune system that’s compromised by chemotherapy, HIV infection or other conditions.
- Having cystic fibrosis, an inherited disease that results in thick, sticky mucus in the lungs and digestive tract.
