I'm going to guess hematoma just from the description and tussle between the dogs!
A hematoma is sort of a blood/fluid 'blister' -- the flap of the ear is really two pieces of skin (the outer piece that is joined to the top of the head/back of the neck and the inside piece that comes up from the ear canal/inside of the ear and they 'seal' together).
When an injury happens (and this happens most anywhere in the body) the body tries to send a protective fluid to 'protect' that injury but often on dogs the fluid builds up until if forms a darned big *sore* bubble.
There are three things the vet will do or tell you to do:
1. The first is to simply do nothing. Often in about 6 months or maybe longer that fluid will not only stop collecting but it will dissipate -- but then again sometimes it never goes away or becomes extremely painful.;
2. The next easy/simple thing is to simply aspirate that 'bubble' (the vet inserts a syringe needle in there and sucks out that bloody/watery fluid). Now however, because this is from an injury, the body may continue to weep into that 'bubble' and it may fill up again ... and sometimes you can 'drain' that 2-3-4 times. (I've actually aspirated them myself -- but it's not something I'd suggest someone do with a dog they don't feel 100% comfortable will allow them to do a procedure like this on them without fuss.) Aspirating it is easy -- it's not a big deal to 'heal' but as I said you might have to do it more than once.
3. Some vets prefer to do a fancier surgery -- essentially what they will do is slit open the inside of the ear flap and using a punch (like a punch biopsy thing) they will actually put holes inside that inner flap and then sew it back up. This creates a "drain" so fluid can get back out. It tends to be messy to heal and it can be darned sore.
But then, #3 is why I learned to aspirate my own dogs hematomas. But going at your dog with a syringe/needle can be way way more than most folks would want to handle. But that describes it.
I honestly doubt bot fly unless this is a dog that spends a ton of time outdoors -- and usually the ear wouldn't be a place the bot fly would necessarily go for. Shoulder? Top of head? yeah -- but probably not an ear (body temp is a big deal to the bot fly **I think**).
