Seems like Dr Sinn took the technique with him when he retired. Till this date I have not encountered anyone who knows how to and has the expertise and willingness to do it for cosmetic reason.
I talked with Heggie but he was not willing to perform this at least that was the impression I got. Did not directly mention the ML3 but he did say there were other alternatives but did not fully mention what.
I contacted Lazlo. Lestat. And seems like they do not know either.
So there is a possibility this procedure is no longer available in the whole world.
Its such a shame.
