My father aged 59 years while standing in a bus fell down due to sudden brake. He got a cut on the backside of the right portion of the head and he had to do 5 stitches. At that time the doctor had bandaged his forehead. But after 2 days he opened the bandaage and asked not to do any bandage or dressing as it will heal faster. My father is resting at home but still I wanted to know if it is safe to keep the stitches open like this without any bandage. Today is the fourth day and the stitches has not been cut still. Do he needs to clean the area with dettol and apply any ointment?
