By my estimates, about 50% of people will experience no loss in sensation. They tend to be younger patients, early 20s. Other than surgeon skill, much of it has to do with the type of procedure done. Large advancements are much more problematic than small reductions for example and individual anatomy. Another 40% experiences reduction in feeling but not elimination. They typically describe it as feeling different or like it's a little tight. No one has said it's problematic for them yet. The one that seems to bother people more is the upper lip, which shouldn't be an issue unless you're having lip work done or work on the cheekbones. It seems to be a side effect of SARPEs too somehow.
