Had a revision otoplasty 4 months post-op. How long do I wait for another revision otoplasty?

I had a revision otoplasty 4 months post-op and it was mostly a failure. My surgeon said it was OK to have it done then while others say to wait at least 6 months after an otoplasty. He also said I can sleep without a headband. Anyway, say I can get another revision from my surgeon: should it be as soon as 4 months post-op again or could that result in another failure?
