Usually, patients with acute sinusitis can be cured by active treatment with continuous medication for about 1 week, but the specific treatment time is also related to the patient himself and the medication. If the patient is a healthy adult with a strong body resistance and has mild symptoms, he or she can be cured in 5-7 days after active treatment with sufficient antibiotics. If the patient has low resistance and the disease is severe, the treatment time needs to be relatively longer, about 10-15 days. Children and the elderly generally do not have as good a prognosis as adults, and the course of treatment will be prolonged, requiring about 2 weeks of continuous medication to achieve significant results. If the inflammation is not treated thoroughly and the course of the disease is prolonged, it may turn into chronic sinusitis, which usually requires puncture and sinusoscopy treatment, and the course of treatment is longer, requiring 3-4 weeks to cure. Acute sinusitis is mainly treated with medication, as acute sinusitis is mostly caused by bacterial infection, so antibiotics can be applied. Nasal decongestants can also be applied in the nasal cavity to relieve nasal congestion and facilitate the ventilation and drainage of the nasal passages, and nasal decongestants can be used for no more than 1 week. In addition, nasal saline or hypertonic saline rinses can be used to reduce mucosal edema. In the treatment of acute sinusitis, sensitive antibiotics should be chosen as much as possible and used in adequate amounts in order to shorten the course of treatment.
