We’ve had a couple of members who’ve had robotic ES surgery. I think both have had a good outcome. The first one was done a year or more ago, & I’m not sure we got any specific details about how much styloid was removed. The second one, & likely the one to which you refer, is adriene61.
The best I can tell you is that robotic surgeries of all kinds are still relatively new, & the outcome of any surgery is related to the skill of the surgeon doing the surgery whether robotic or “old style” i.e. w/o the robot.
I think what’s most important is that you have a surgeon in whom you feel confident & with whose surgical approach you agree. If the surgeon happens to be trained in robotic surgery then you get to experience surgery via the most modern tech. If the surgeon does not do robotic surgery then you will experience great manual skill & dexterity.
Robotic surgeries do tend to be less invasive which would predispose the patient to a lower likelihood of post op surgical “side effects”, however, I don’t know that there is enough significant statistical evidence to promote robotic over traditional surgeries at this time. I expect one day all surgeries will be done robotically though.
