Another vote for repairing it here! The dog will survive if you don't, but there is a significant risk of ongoing nasal complications. The repair technique doesn't need to be complicated, single layer closure is likely to be adequate, but it must be done well will no tension on the sutures and bony support under the suture lines. As Rachel and Norman have said, if the first attempt fails, subsequent attempts are likely to be more tricky.

It’s certainly a decent size grossly and almost certainly the lack of bone support underneath will exceed the visible fistula by a margin of about double. This is important as any repair will need to have the suture lines over bone to avoid dehiscence. Rachel’s advice is sound as the best chance to repair it surgically is the first procedure. Going in after failure makes life very difficult.
So - does it need done? Devil’s advocate here. Is it functional or not? That means does the dog suffer discharge and sneezing from debris entering. It’s obviously chronic and it may well be that there are no turbinates left and there are few adverse symptoms.
I’d recommend surgery though

Dear Aly

The oronasal fistula was there pre-dental work- you just couldn’t see it because the tooth was there. I would always prefer surgical repair otherwise the dog will have ongoing issues with rhinitis. The repair must be carried out by someone who knows how to repair these otherwise it will fail and then be a waste of time/ money. It will be important to have a thorough discussion with the client regarding risks of leaving this at it is.
