What condition is characterized by inflammation of the sinuses?

Sinusitis is the correct answer because it specifically refers to the inflammation of the sinuses, which are air-filled cavities located within the skull surrounding the nasal passages. When these sinus cavities become swollen or inflamed, typically due to infection, allergies, or other factors, it leads to the symptoms associated with sinusitis, such as nasal congestion, facial pain or pressure, and a reduced sense of smell.

Other conditions listed do not relate to sinus inflammation. Rhinoplasty is a surgical procedure to change the shape of the nose, while otitis media involves inflammation of the middle ear, and bronchitis refers to inflammation of the bronchial tubes in the lungs. Understanding these distinctions helps clarify why sinusitis is the appropriate choice for this question.
