The severity of a bilateral maxillary sinus cyst needs to be determined by its size and clinical symptoms.
Maxillary sinus cyst belongs to a type of sinus cyst, which is a benign lesion with a low rate of malignancy. Its cause is mainly due to inflammation, infection, trauma, tumor, oral disease and other factors.
Usually, small maxillary sinus cysts do not cause uncomfortable symptoms and are only detected during a physical examination; such cases are not serious and can be observed and followed up.
When the cyst is large, the patient will have nasal congestion, runny nose, facial swelling, headache and other clinical symptoms. Patients can take oral vitamin drugs, such as vitamin C, as prescribed by the doctor. For patients with secondary bacterial infection, antibiotic drugs such as amoxicillin and roxithromycin can also be taken orally. If necessary, traditional surgical treatment, simple nasal endoscopic surgery, and nasal endoscopy combined with lower nasal passage opening can be performed.
Therefore, patients with the presence of maxillary sinus cysts are advised to take appropriate measures according to the specific condition as prescribed by the doctor.
