Frontal sinusitis can first be divided into two types: acute frontal sinusitis and chronic frontal sinusitis. Acute frontal sinusitis is an acute purulent infection of the sinus mucosa, mostly due to upper respiratory tract infection, which indirectly causes inflammation of the nasal mucosa, resulting in bacterial infection of the sinus opening. First of all, to target anti-inflammatory and anti-edema treatment, you can take oral amoxicillin and cefradine capsules, and use nasal spray drug colecalciferol to open the edematous sinus orifice, and drain the purulent secretions in the frontal sinus smoothly to relieve the headache. When acute frontal sinusitis is not treated in time or improperly treated, so that the mucosa is severely damaged and loses its normal function, it can become chronic frontal sinusitis. And chronic frontal sinusitis has long-term purulent inflammation, accompanied by headache and dizziness. At this time, you can insist on using amoxicillin with rhinitis capsules orally for about 2 months. If the treatment is not complete, surgery can be considered.
