What condition is caused by a blockage in the drainage of the sinuses?

Sinusitis is a condition characterized by the inflammation and swelling of the sinus lining, often resulting from blockage in the drainage pathways of the sinuses. This blockage can prevent mucus from draining properly, leading to an accumulation of fluid and creating an environment conducive to bacterial growth. The blocked sinuses can result in symptoms such as congestion, facial pain, pressure, a reduced sense of smell, and potentially fever.

Rhinorrhea refers to a runny nose, which can occur in various conditions but does not specifically indicate a blockage in sinus drainage. Allergic rhinitis is an allergic reaction that causes sneezing, runny nose, and nasal congestion but is not synonymous with sinus blockage. Nasal polyps are growths in the nasal passages or sinuses associated with chronic inflammation but are conditions rather than a direct result of blockage; they can contribute to sinus obstruction rather than be defined by it.

In summary, sinusitis is the most directly linked condition to the blockage in sinus drainage, leading to the characteristic symptoms associated with inflammation and infection.
