My little Eve has just suffered this! She had to have a GA to have it drained, cut vertically in 3 places and stitched. At the next check, the stitches were still oozing and one had split so she had a sedation to clean it all and flush her ear. Then she had to have a sedation to have the stitches taken out!
All the 'knocking out' was because her ear was so saw and inflamed that she wouldn't let you even touch the inner side! Basically, she had a very deep ear infection. Just after we got her, she started scratching her ear and holding it at a funny angle. I asked for ear drops, the vet looked in her ear and said no infection, just hairs irritating her that were so deep they would have to be removed under GA. We felt she was far too young for that ( and because Pierre had only just died, within a year of Louis and we were scared :( ) so decided to wait til she was a little older! We booked her GA for the ear pluck when we saw her ear canal was closing but 2 days before the op, she developed the hematoma. After the op, the vet said she had a severe ear infection and gave me the very drops I had asked for in the 1st place! and there were only 3 hairs to remove!!!!!!!
All the frenchie people I spoke to before the op, said not to leave the hematoma as they always developed cauliflower ears!
She is still on ear drops but her ear is so comfortable now, she lets you put the drops in and the vet can even look inside without her fighting! She's been left with a few bumps where the stitches were and a raised line where the split was, but it has only been 3 weeks so it may go down in time....she's 8 months btw :)
