The diagnosis of sinusitis, which is generally considered to be sinusitis, is mainly based on the medical history, through the doctor’s nasal endoscopic examination and through sinus CT examination, which reveals that there is an inflammatory purulent infection inside the sinus in order to diagnose sinusitis. Sinusitis is usually diagnosed clearly after the clinician, you can do the following medication under the guidance of the doctor: First, you can do nasal rinsing, which can rinse out most of the pus in the nasal cavity to avoid excessive retention of pus and poor drainage, resulting in sinusitis is not easy to get well. Secondly, anti-inflammatory and antibacterial treatment can be carried out. Bacterial culture of nasal secretions can be done to find out the sensitive drugs so that anti-inflammatory treatment can be carried out. Third, you can take oral mucus promoter to promote the discharge of pus, thus promoting the recovery of the disease. In addition, nasal spray hormone can be used to reduce mucosal edema and reduce mucosal inflammation, so as to carry out symptomatic treatment. Short-term application can be done with nasal mucosal constrictors, but the application should preferably not exceed one week. Generally, acute sinusitis is treated medically, and surgery can be considered for sinusitis with a history of more than three months and repeated medication that is ineffective.
