Inflammation of the mucous membranes of the maxillary, septal, frontal and pterygoid sinuses is collectively referred to as Nasosinusitis. Nasosinusitis is a non-specific inflammation of the mucous membrane of the sinuses and is a common rhinological condition. The main features of acute purulent sinusitis are nasal congestion, pus, and headache, while chronic purulent sinusitis is often secondary to acute purulent sinusitis, with pus as the main manifestation, accompanied by varying degrees of nasal congestion, headache, and olfactory disturbance. Usually pay attention to exercise, work and rest, dress moderately, breathe more fresh air, avoid dry nose, do not easily drop nasal medicine. Timely diagnosis and treatment of nasal lesions and adjacent focal infections need to be treated.
