The sinuses are hollow cavities in the facial and skull bones, primarily around the nasal and ocular regions. They play a crucial role in producing mucus, maintaining the air's moisture, and trapping bacteria and debris to prevent them from entering our lungs. Additionally, sinuses contribute to our ability to speak and reduce the weight of our skulls.
Sinusitis
Sinusitis occurs when the tissue lining the sinuses becomes inflamed or swollen, which can block the sinus openings and cause symptoms such as:
- Facial pain or pressure
- Nasal congestion
- Post-nasal drip
- Thick, discolored nasal discharge
- Cough or throat irritation
Several factors, including the following, can contribute to this condition:
- Viral infections
- Bacterial infections
- Allergies
- Nasal polyps
- Deviated nasal septum
