Gentamicin is often not used for the treatment of rhinitis and is mainly seen in the following clinical analyses: 1. For acute rhinitis, which is mainly caused by viral infection, gentamicin treatment has no effect. 2. For chronic rhinitis, which is not directly related to bacterial infection, the application of gentamicin is not too significant regardless of rinsing or other treatments. 3. For patients with allergic rhinitis, which is mainly caused by allergens in the nasal cavity, there is a metabolic reaction in the nasal cavity, which is not related to bacterial infection, and the application of gentamicin has no effect. 5. For patients with atrophic rhinitis, the clinical practice is mainly to keep the nasal cavity moist, or to apply topical erythromycin, gentamicin ointment and other topical antibiotic ointment, for symptomatic treatment treatment. If there is a large amount of pus in the nasal cavity, you can also apply antibiotics for flushing treatment as appropriate, but because of the ototoxicity of gentamicin, side effects are relatively large clinically not recommended for application.
