What does bilateral maxillary sinus cyst mean?

Generally, bilateral maxillary sinus cysts refer to cyst-like structures appearing in the maxillary sinuses on both sides of the human body. The detailed analysis is as follows:

Bilateral maxillary sinus cysts are fluid-filled cystic masses that develop within the maxillary sinuses on both sides of the nasal cavity. Most often, they result from blockage of the mucosal glands in the maxillary sinus, causing secretions to accumulate and not drain properly. For example, rhinitis or sinusitis can cause mucosal inflammation, leading to narrowing of glandular openings. Trauma or surgical injury to the mucosa may also result in secretion retention. In addition, abnormal sinus development or long-term exposure to irritants can increase the likelihood of cyst formation. These cysts usually grow slowly and may be asymptomatic in the early stages.

In daily life, it's important to protect the nasal cavity. Wear a mask when outdoors in dusty or smoggy conditions to reduce mucosal irritation. Maintain nasal hygiene by gently rinsing with saline solution, and avoid forceful nose blowing. Diet-wise, minimize spicy and greasy foods and increase intake of vitamin-rich foods. Maintain regular sleep patterns and avoid staying up late to strengthen immunity and reduce the risk of sinus inflammation. If symptoms such as nasal congestion, headache, or facial pressure/pain occur, seek medical evaluation promptly.
