The severity of symptoms of acute sinusitis and chronic sinusitis are not quite the same, but they can all be examined by nasal examination, postural drainage, taking X-rays and CT. 1, nasal cavity examination. In patients with acute sinusitis, there will be congestion of the middle turbinate and middle nasal passages during the examination. Other parts of the inside of the nose may also be congested, but mostly in these two areas. When examined, patients with chronic sinusitis will find that their middle turbinate is hypertrophied, and polyps are visible in some patients. 2, postural drainage. If the patient is suspected of having sinusitis, but no abnormal secretions are found in the nasal passages, this can be used to help the doctor diagnose what kind of disease the patient is suffering from. 3.Taking X-rays. It is also possible to tell if a patient has sinusitis. If the patient is sick, the inside of the nose will look cloudy and have low light transmission. A CT scan is a much clearer image than an X-ray, and can better help the doctor determine what is going on inside the patient’s nose. When you suspect that the patient’s sinusitis is caused by dental disease, you should do a dental examination. Some people are afraid to go to the hospital, and when they have a runny nose and congestion, they think they have sinusitis and want to buy their own medication to treat it. If you really suspect that you have the disease, please go to the hospital for a clear examination.
