Introduction
In general, treatment methods for maxillary sinus cyst rupture with yellow discharge include routine care, nasal irrigation, medication, traditional Chinese medicine regulation, and surgical intervention. In addition, patients should follow medical advice to complete the full course of treatment and undergo regular follow-up examinations to monitor nasal recovery. If symptoms such as increased yellow discharge, foul odor, or worsening headache occur, prompt medical attention is required to adjust the treatment plan.
Generally, treatment methods for maxillary sinus cyst rupture with yellow fluid discharge include routine care, nasal irrigation, medication, traditional Chinese medicine (TCM) regulation, and surgical intervention. Specific analyses are as follows:
1. Routine Care
After cyst rupture and continuous discharge of yellow fluid, it is essential to maintain nasal hygiene. Avoid forceful nose-blowing to prevent a sudden increase in nasal pressure that may lead to infection. Ensure adequate rest and avoid excessive fatigue. Maintain a light and easily digestible diet, and consume more vitamin-rich fruits and vegetables to enhance immunity and support the healing of nasal mucosa.
2. Nasal Irrigation
Nasal irrigation helps remove residual yellow discharge and bacteria from the nasal cavity, reducing the risk of infection. Normal saline or specialized nasal irrigation solutions are commonly used. During irrigation, slightly tilt the head forward to allow the solution to flow out naturally. Gentle rinsing helps keep the nasal passages clear and alleviates discomfort caused by irritation from the discharge.
3. Medication
Medication primarily aims to prevent infection and reduce inflammation. Patients may take medications such as cefixime dispersible tablets, budesonide nasal spray, and eucalyptus citronellal enteric soft capsules under medical guidance. The first two help prevent infection and reduce mucosal inflammation, while the latter promotes the drainage of nasal secretions.
4. Traditional Chinese Medicine (TCM) Regulation
According to TCM, maxillary sinus cysts are often associated with phlegm-dampness stagnation and damp-heat in the lung meridian. Treatment typically involves herbs that clear heat, eliminate dampness, resolve phlegm, and dissipate nodules, such as Xinyi Rhinitis Pills and Cang’erzi Rhinitis Capsules. Acupuncture at points like Yingxiang (LI20) and Hegu (LI4) can regulate meridian qi and blood flow, helping to relieve nasal discomfort.
5. Surgical Treatment
If the cyst repeatedly ruptures with frequent yellow discharge, or if the cyst is large enough to compress surrounding tissues, surgical intervention is required for definitive treatment. The most common procedure is endoscopic maxillary sinus cystectomy, which is minimally invasive and allows for rapid recovery. This surgery completely removes the cyst and reduces the likelihood of recurrence.
In addition, patients should follow medical advice throughout the treatment process and undergo regular follow-up visits to monitor nasal recovery. If symptoms such as increased yellow discharge, foul odor, or worsening headache occur, prompt medical attention is necessary to adjust the treatment plan and prevent chronic rhinosinusitis due to prolonged illness.
