Hi
If the hole is big it normally requires surgery,but if the hole haven't got closed since 6months it is less likely it will heal.
So I think you should go for surgery.
While in an experienced hands the surgery takes 1hour or so.
Post surgery atleast 7 days rest is advisable.
No frank complications as such of the surgery are reported.
