Chronic Sinusitis Specialists in Telangana

Causes of Chronic Sinusitis

Chronic sinusitis develops when the sinus linings remain inflamed due to persistent bacterial or fungal infection, chronic allergic rhinitis, or structural issues such as a deviated septum or nasal polyps that block normal drainage. Environmental irritants like smoking and air pollution, immune system disorders, and dental infections spreading to the sinuses can also contribute. Biofilm formation by bacteria within the sinuses is thought to make some cases especially resistant to standard antibiotic treatment.
