Chronic sinusitis means that a sinusitis becomes persistent and lasts for longer than 12 weeks. Chronic sinusitis is uncommon. Fungal infection
of sinuses is very rare.
If routine medical treatments are not offering any relief to you then you must consult a ENT specialist
and get properly investigated by getting following tests done.

Surgery is used mainly if the condition does not improve with the above medical treatments. The main purpose of surgery is to improve the drainage of the affected sinus and remove nasal polyps,if they are present.
The most common operation is called functional endoscopic sinus surgery
(FESS). This can improve sinus drainage and ventilation and help to restore normal function to the sinus. This operation is minimally invasive (causes little damage) and usually has a high success rate in relieving symptoms of chronic sinusitis.
