As in any surgical procedure, severe obesity may also hinder access to the target. Kuntz nerves are tiny accessory nerve fibers, which branch away from the main sympathetic trunk. Many surgeons throughout the world routinely divide the T2, T3, and sometimes even T4 levels of the sympathetic nerve trunk, which can result in bothersome to severe compensatory sweating. It is our belief that by dividing only T2 and any present Kuntz nerves, our patients are not at risk for a return of sweating and compensatory sweating should be minimal. While any surgical procedure has some degree of risk associated with it, ETS is a very safe procedure with minimal side effects.
Many patients report that compensatory sweating decreases over time.
However, few patients regard this as a major problem. Typically, patients report feeling a sensation rather than actual perspiration. This usually resolves on it's own with time. This symptom is purely cosmetic and does not Impair vision. In the very rare event that the condition is permanent, it can easily be corrected with plastic surgery.
