Maxillary sinusitis does not usually heal on its own, and may be cured with aggressive medication and, if necessary, surgery. If maxillary sinusitis does not receive timely and effective treatment, it can be transformed into chronic maxillary sinusitis, which will not be cured by itself, so patients with maxillary sinusitis should consult a doctor in time and follow the doctor’s instructions to carry out the appropriate treatment. At present, the main treatment method is drug treatment, if the drug treatment is ineffective, it can be appropriate to be surgical treatment. Commonly used drugs include intranasal decongestants (such as hydroxymetazoline hydrochloride spray, etc.), nasal glucocorticoids (such as mometasone furoate, budesonide, etc.), which can significantly improve the patient’s symptoms and reduce the inflammatory response, and sensitive antibiotics should also be given to those who have clearly identified the causative organisms so as to control the infection. For those who are ineffective in drug treatment, endoscopic sinus surgery can also be performed. Patients with maxillary sinusitis should follow the doctor’s instructions to actively standardize the use of medication and treatment, not blindly use or stop medication, so as not to affect the condition.
