Suporn is retiring at the end of 2019 and there's now a lottery to get a date. A new surgeon, Dr Bank, is in training with Dr Suporn and will take over. I don't know of any public photo's of Dr Banks work, although I have seen one that looked like a very good example of Dr Suporn's work. Preecha (of PAI) trained Suporn (and many other surgeons in Thailand), but it was a very long time ago and Suporn's come up with his new technique since then. Chettawut has used at least some of Suporn's technique, not sure exactly.
