This is the common name used to the appearance of sweat in other parts of the body after the sympathectomy was done. The compensatory sweating also known as (reflex sweating or compensatory hydrosis) can appear on the lower legs, thighs, abdomen, or the back. Generally speaking everything from the nipple line up will be dry after ETS. All patients will get some sort of compensatory sweating (compensatory hydrosis or reflex sweating) which does not have necessarily any correlation to the amount of hand sweating existing before the operation. The majority of the patients will get it on a level that is acceptable by the patients, which we call mild to moderate. Between 3 to 5% of the patients will get it on a severe level which will make those patients unhappy ones. The compensatory sweating (compensatory hydrosis or reflex sweating) is a byproduct of the operation no matter what method was used. It really depends on how close the follow-up is being conducted by the different surgeons to give a definite statistical analysis of those cases.
