Sinusitis and Chest Infection: Sinus must be treated first.
There is a high correlation between sinusitis and bronchitis. So, it is important to treat any sinus infection quickly. Symptoms of sinus disease may include facial pain or pressure, difficulty in breathing through the nose, a persistent bad smell in the nose, copious discharge either blown out or as post nasal drip. Sinusitis is diagnosed by physical examination of nose, nasal endoscopy and CT imaging of the sinuses.
Bronchitis is a medical condition usually caused by viral or bacterial infection causing the lining of the bronchial tubes to become inflamed. Sinobronchial syndrome is a combination of sinusitis and the resulting lower respiratory tract symptoms such as bronchitis or asthma.
The sinus disease resulting in lower airway symptoms such as asthma and bronchitis is due to a constant post nasal drip of inflammatory and infective secretions from the back of the nose to the back of the throat. This throat irritation may cause bronchial constriction by a reflex transmitted by the nervous system. Also the postnasal drip of inflammatory secretions from the upper airway may create a secondary inflammatory reaction of the lungs, causing either asthma or bronchitis.
So it is important to treat the primary cause, the sinusitis. If the sinus condtion is chronic, it must be dealt with surgery like FESS as shown in this case.
