What is bilateral sinusitis?

Bilateral sinusitis generally refers to bilateral ethmoid sinusitis, an inflammatory condition of the ethmoid sinus mucosa caused by infections from bacteria or viruses. The details are as follows:

There are four pairs of paranasal sinuses within the nasal cavity: maxillary, ethmoid, frontal, and sphenoid sinuses. Ethmoid sinusitis usually occurs when a patient's resistance or immunity is reduced, allowing pathogens such as bacteria or viruses to cause infection. Additionally, individuals with chronic conditions like chronic rhinitis or deviated nasal septum may experience inflammation spreading to the ethmoid sinuses, leading easily to bilateral ethmoid sinusitis. This condition can result in discomforts such as headache, insomnia, and fatigue. As the disease progresses, patients may develop persistent low-grade fever and nasal congestion. In severe cases, loss of smell may occur. Some patients who do not receive timely treatment may develop complications such as orbital cellulitis or retrobulbar neuritis.

Once bilateral ethmoid sinusitis is diagnosed, it is recommended to promptly follow a physician’s guidance and use antibiotics such as levofloxacin capsules or amoxicillin capsules to suppress pathogens, control inflammation, and relieve symptoms. Additionally, maintaining a light yet nutritionally rich diet can also help improve symptoms.
