Chronic Sinusitis is a persistent inflammation of the sinus cavities that lasts for 12 weeks or longer, causing symptoms such as congestion, facial pain, and reduced sense of smell. Treatment depends on the cause and severity of the condition, focusing on reducing inflammation, improving drainage, and preventing flare-ups. Common non-surgical treatments include saline nasal irrigation, which helps clear mucus and allergens, and nasal sprays to reduce swelling inside the sinuses. If an infection is present, short-term antibiotic therapy may be used. Managing underlying issues like allergies, asthma, or environmental irritants also plays a key role in controlling symptoms. When conservative Treatments fail, minimally invasive procedures may be considered. Balloon sinuplasty is a popular option, using a small balloon to open blocked sinus passages and restore natural drainage. In more advanced cases, functional endoscopic sinus surgery (FESS) may be recommended to remove polyps or diseased tissue. Lifestyle modifications-such as using humidifiers, staying hydrated, and avoiding irritants-can help maintain long-term sinus health. With a customized treatment plan guided by an ear, nose and throat (ENT) specialist, most patients can achieve lasting relief and improved breathing.
