For the treatment of foreskin glans, alcohol should not be used for disinfection of the mucous membrane because it is very irritating. The ratio of potassium permanganate to water is 1:5000. You can use potassium permanganate to soak once in the morning and once in the evening for 15 minutes each time or iodophor wipe once in the morning and once in the evening; if the inflammation is strong, you can use topical paregoric ointment once in the morning and once in the evening; for acute superficial glans, after iodophor wipe, you can apply topical erythromycin ointment or Bactrim ointment. For patients with repeated episodes of glans penis, circumcision can be done; for patients with long foreskin, the foreskin should be opened and cleaned daily to keep the foreskin cavity clean and hygienic; circumcision must be done in time for circumcision. You can’t use alcohol to disinfect glansitis.
