Improvement of nasal dryness and crusting may be caused by environmental dryness, dry rhinitis and atrophic rhinitis, and treatments include nasal rinsing, nasal drops, and intranasal application. 1. Nasal rinsing: the purpose is to clean the nasal cavity, remove the scabs and odor, so that the atrophic mucous membrane gets stimulated and active. Warm saline or potassium permanganate solution 1∶(2000～5000) can be used for rinsing. 2. Nasal drops: use 1%~3% streptomycin solution to inhibit bacterial growth, reduce inflammatory erosion and facilitate epithelial growth; use 1% compound menthol camphor oil, cod liver oil, paraffin oil, etc. to lubricate the mucous membrane, promote mucosal blood circulation and soften the pus crusts, so as to make it easier to blow out. 3. Intranasal medication: applying 1% neostigmine in the nose can promote mucosal vasodilatation; using 0.5% hexenylestradiol oil drops or coated nose can reduce scabs and odor; using 25% glucose glycerin drops to inhibit the decomposition of nasal secretion; using 50% dextrose drops to stimulate the secretion of mucosal glands. Nasal dryness and crusting people need to regular hospitals, follow the doctor’s instructions to standardize the use of drugs and treatment.
