When you had your consultation did you select three implant sizes with your surgeon to be ordered?
For example I got 400cc, 425cc and 450cc, so on the day I had an option to choose. If you did and you ordered a bigger size than 375cc then you will be fine to change this on Monday.
However if you didn’t, you need to try and arrange a consultation with your surgeon as soon as possible, like today, as they need at least 48hours before your operation to order in the implants.
I would suggest calling into MYA and asking to speak to your patient coordinator x
