Well medically it is possible to still have drainage from canal 12 weeks after having Hong Kong flap proceedure. The success of this operation is because the vasculature (blood supply) the flap provides. If you have had mastoidectomy, chronic abcesses with cholesteatoma and subsequent ear drainage of course, I would be willing to theorize the healing capacity is decreased in your case because of the longevity and degree of problems with cholesteatoma. I wonder why it take so long for physician to decide to do Hong Kong flap- it is not a seriously difficult surgery and has 90% success rates.
I would be very very cautious about bilateral implants with this dealio u have. Tell me this is only one side have the problem with cholesteatoma or both. Just by reading it sound like the disease process and subsequent proceedures cause you to be full deaf in your other ear. If the origianally deaf ear never had the infections, abcesses, surgeries, removal of bone, creation or drainage cavity etc, why not just do one, less chance for complication. But then again, if this is problem you have always have with the cholesteatoma and both eustachian tubes then I wouldn't do it if it were I.
Either way good luck with healing and I do hope for the very best for you, it sounds like you have dealt with enough already. Get Well soon.
