As far as comparability Dr Haben with Dr Kim goes - what does Dr Haben say about singing, shouting, screaming, speaking loudly after the surgery? Prof Nawka in Berlin told me that all of this is impaired or should be avoided, Dr Kim said that once the healing is finished, after 2 months one can sing and after a year it should be ok to do all of this - we know from the experiences of others that some volume loss occurs though and that in some cases singing does not work out as well as hoped, i most cases it seems to be very good though. Since the techniques seem to differ quite a bit, I would be interested in that. I guess when it comes to normal daily speech alone, the results seem to be good in both cases.
