Introduction
In general, the rupture of a nasal sinus cyst with discharge of yellow fluid may be caused by natural enlargement of the cyst, sudden increase in nasal pressure, chronic sinusitis, allergic rhinitis, nasal polyps, or other factors. Patients can choose appropriate management approaches such as conservative treatment, medication, or surgical intervention based on their specific condition. Daily maintenance of nasal hygiene is important, including regular cleaning with saline solution, and avoiding adverse environments such as dust and irritating gases.
Under normal circumstances, a nasal sinus cyst rupturing and discharging yellow fluid may be caused by natural enlargement of the cyst, sudden increase in nasal pressure, chronic sinusitis, allergic rhinitis, or nasal polyps. Depending on the specific situation, patients can choose appropriate management methods such as general care, medication, or surgical treatment. A detailed analysis is as follows:
1. Natural enlargement of the cyst
Cysts form when secretions from the nasal sinus mucosa are retained for a long time. As the fluid accumulates, the cyst gradually enlarges, causing the cyst wall to thin and become prone to rupture and discharge yellow fluid. It is recommended to maintain a light diet, drink plenty of water, avoid forceful nose-blowing, and reduce nasal irritation.
2. Sudden increase in nasal pressure
Sudden rises in nasal pressure due to severe coughing, sneezing, or forceful bending can exert pressure on the sinus cyst, leading to rupture. Avoid intense physical activities, control the force when sneezing, and keep the nasal passages clear in daily life.
3. Chronic sinusitis
Long-term inflammatory stimulation of the sinus mucosa leads to thick, retained secretions that form cysts. When inflammation worsens, the cyst becomes more likely to rupture. Under medical guidance, patients may take medications such as clarithromycin dispersible tablets, eucalyptus oil and pinene enteric soft capsules, and budesonide nasal spray, and consistently perform saline nasal irrigation.
4. Allergic rhinitis
Allergens cause nasal mucosal congestion and swelling, increasing secretions and promoting cyst formation. Repeated irritation makes the cyst prone to rupture. Follow doctor's advice to use levocetirizine hydrochloride tablets, montelukast sodium chewable tablets, and mometasone furoate nasal spray, while avoiding allergens such as pollen and dust mites.
5. Nasal polyps
Nasal polyps block the sinus openings, preventing normal drainage of secretions and resulting in cyst formation. Pressure from the polyp may lead to cyst rupture. Treatment options include prednisone acetate tablets, roxithromycin capsules, and Biyuan Tongqiao Granules. In severe cases, endoscopic nasal polypectomy and cyst removal surgery may be required.
Maintain good nasal hygiene by regularly using saline solution to clean the nasal cavity; avoid exposure to dust and irritating gases; individuals with allergies should identify their allergens and take preventive measures; seek timely medical attention for symptoms such as nasal congestion and runny nose to prevent prolonged illness and cyst development.
