Inflammation of the right maxillary sinus refers to unilateral maxillary sinusitis, which can be either a bacterial or fungal infection. The clinical symptoms of the patient are mainly unilateral nasal congestion, runny nose, nasal disinflation, unilateral toothache, cheek pain and other discomfort. Generally, the course of the disease is acute maxillary sinusitis within 3 months, and more than 4 months, it is generally considered chronic maxillary sinusitis. The clinical treatment of acute maxillary sinusitis can be treated with some antibiotics, mucus promoters, nasal spray hormones, nasal irrigation, etc. For unilateral chronic maxillary sinus inflammation, if the clinical examination reveals abnormalities in the hooked protrusions, the presence of nasal tract sinus complex obstruction, and long-term drug conservative treatment is ineffective, you can do nasal endoscopic maxillary sinus opening surgery, the effect of this surgery is still good.
