Nasal polyps

Nasal polyps are common diseases of the nose and are also related to certain systemic diseases. It is the result of tissue edema due to a long-term inflammatory reaction in the nasal mucosa. Nasal polyps mostly come from the middle nasal passage sinus, nasal passage complex and ethmoid sinus. The highly edema nasal mucosa swells from the middle nasal passage and sinus opening to the nasal cavity to form polyps. Due to the multiplicity of causes and the obvious tendency of postoperative recurrence, it occupies an important position in nasal diseases.
