Maxillary sinusitis is a non-specific inflammation of the mucosa of the maxillary sinus and is a common and prevalent disease in rhinology. Maxillary sinusitis can be treated with nasal sprays to relieve the swelling of the nasal mucosa and promote the drainage of pus from the maxillary sinus, thus improving the patient’s dizziness and headache symptoms. Specific medications include coleus nasal spray, budesonide nasal spray, endosonide nasal spray, and tretinoin nasal spray. It can also be treated with oral anti-inflammatory drugs to eliminate the swelling of the mucous membrane of the nasal cavity and sinuses and to relieve the patient’s symptoms. Mucus-promoting agents can be used to improve the nature of mucus and promote the discharge of purulent secretions, as well as to promote the activity of the mucous membrane cilia in the maxillary sinus and nasal cavity, which facilitates the drainage of the maxillary sinus and improves the patient’s symptoms. Anti-inflammatory drugs and mucus promoting agent drugs mainly include amoxicillin, cephalosporin anti-inflammatory drugs, clarithromycin, genotone, nasal abdomen and orifice granules, oral solution for sinusitis, etc. However, if the maxillary sinusitis is recurrent or conservative treatment is not effective, you can go to the regular hospital otorhinolaryngology department to perform sinus CT examination to clarify whether open sinus surgery is feasible.
