Orthognathic revision surgery consultation, cost information

I had double jaw surgery 3 years ago, and I am not dissatisfied with the results of the surgery, but I am looking into double jaw revision surgery because I want to make my face shorter. There are
 
two hospitals I have consulted with so far
 
- Hwang Soon-jeong's consultation review -
 
 The director said that the face does not need double jaw surgery and did not recommend double jaw surgery. However, if you really need to do it, I recommend chin tip and buccal cortical bone resection instead. The cost was around 1400 and they said the tip of the chin could be reduced by about 5mm.
Also, since the philtrum length is not short, there is a possibility that the upper teeth may not be visible during double jaw surgery, so he suggested that I perform philtrum reduction surgery first and then consult again.

- EverM consultation review -
 
They recommended double jaw surgery + chin tip to reduce the maxilla length by about 5mm and the tip of the chin by 1mm. The cost is about 1,600.
 
For those looking for orthognathic revision surgery,
 I recommend a hospital worth visiting.
