sorry to let you know but your result is not good at all, a hole is only one of problems I can see.
It seems more like a tunnel, which would be pretty difficult to fix as it needs an excision again and then there is a problem with dehiscence again because of lack of tissue and too much stress tension on it. Then a whole healing is compromised and the same problem can occur again.
You need a detailed investigation and precise follow-up. Good luck. Kind regards, Dr. Jo
