Will keeping the bandage on effect the stitches from healing the wound? (Photos)

I was hit in the nose 8 days ago and recieved a broken nose on the bridge and 5 stiches. After 7 days I went to my local walk In clinic to have the stiches removed. He was only able to remove 2 as 3 were not ready and was told to come back in 5 days to see if the remaining 3 were ready to be taken out. He also advised me to keep a bandage on. Will keeping the bantage on effect the stiches from healing the wound? Im scared that the stiches will not be ready to be taken out and the wound may reopen.
