The treatment of granulocyte deficiency pharyngitis includes symptomatic treatment, anti-infection treatment and granulocyte promotion treatment. 1. Symptomatic treatment: granulocyte deficiency pharyngitis mainly manifests as inflammation of the pseudomembrane of the pharyngopharyngeal isthmus, with swelling, necrosis and ulceration of the oral mucosa, and some patients may have pain in the pharyngopharyngeal isthmus, and bleeding may occur in severe cases. At this time, symptomatic treatment can be carried out, the use of anti-inflammatory drugs at the same time with 3% hydrogen peroxide gargle, to keep the oral cavity clean, reduce the chance of infection. 2. Anti-infection treatment: granulocytes are a kind of white blood cells, when granulocytes are lacking, the patient’s immune system will be very easy to get infected, and isthmus is one of them, so anti-infection treatment should be carried out. Clinical anti-infective treatment generally needs to identify the pathogen and then target the pathogenic microorganisms for treatment, mainly for the application of antibiotics or the use of antiviral drugs. 3. Promote granulocyte treatment: granulocyte deficiency is the main cause of granulocyte deficiency in isthmus of pharyngeal inflammation, so systemic treatment can be carried out, the use of bone marrow granulocyte growth and maturation of drugs to promote the increase of granulocytes, such as intramuscular injection of nucleotides. Patients should also stop using drugs that inhibit granulocyte growth. Patients with granulocyte deficiency isthmus generally do not need surgical treatment, patients should be under the guidance of the doctor regular use of medication, to follow the doctor’s instructions, there is any discomfort in time to respond, so as not to aggravate the condition.
