A few months ago, we had a leak that caused some moderate damage to the drywall in the corner of one room. The resulting damage left peeling tape, as well as a gap between the drywall and the ceiling.
The damage to the tape is about 12 inches long, and then the more adverse damage another 12 inches, spreading out from the joint ~2in in either direction, up to the corner of the room.
Looking into this on my own, it seems like it might be possible to redo the tape and joint compound in place, but I'm not sure whether this is actually the correct procedure.
I've also seen people recommend removing a chunk of the drywall and slotting in a replacement chunk, but the details of this (how much to remove, how to ensure the replacement chunk is secure) were unclear to me.
What's the proper method of handling this type of damage?

I think this might be more of an opinion type question but I would just repair the corner and fill the small section where the paper ripped off.
Fill it put a layer of tape let it dry, put a new corner in mud let dry sand and a can of texture should fix it up. If messy with the mud it may take more sanding.
If you cut a section out there will be more repair work if the damaged area was wider and deeper I would cut out but it looks like the back paper is intact.
1 maybe 2 coats of mud should do it from what I see.
