Sinusitis is defined as what?

Sinusitis is defined as the inflammation of the sinuses. The sinuses are air-filled spaces located in the skull around the nose, and when they become inflamed, it can result in various symptoms such as nasal congestion, facial pain or pressure, and reduced sense of smell. This condition can be caused by infections, allergies, or even structural issues within the nasal passages.

Understanding sinusitis as inflammation specifically targets the sinuses helps differentiate it from other respiratory conditions. For instance, inflammation of the lungs would typically refer to conditions such as pneumonia or bronchitis, while infections of the throat and nasal passages are distinct entities with their own specific symptoms and treatments. This clarity around the definition of sinusitis is essential for recognizing its symptoms and the appropriate therapeutic approaches.
