Another treatment option is the local injection of botulinum toxin. This treatment must be repeated when the effect wears off (usually after 3 to 6 months). The price is determined individually and is based on expenditure and consumption. The treatment costs are often not covered by health insurance.
Surgical
Thoracoscopic sympathectomy offers a definitive solution. This involves severing or removing a circumscribed part of the sympathetic borderline pathway that regulates sweating in the corresponding region. This procedure is minimally invasive and involves keyhole surgery. The operation is performed under anesthesia and requires a one-day (outpatient) hospital stay.
The operation usually drains the patient’s hands completely. Mild increased sweating (compensatory hyperhidrosis) often occurs on other parts of the body after the operation (approx. 50%), but the majority of patients who have undergone surgery do not find this very bothersome. In 1.5 to 2 percent of cases, however, patients are severely impaired by the compensatory sweating, and significantly more so than they were due to the original extent of the hyperhidrosis. Some are very disturbed by this in everyday life.
It is extremely rare for a so-called Horner syndrome to occur after the operation. This means that the upper eyelid hangs slightly and the pupil is slightly narrower. However, this has no effect on visual performance. In experienced hands, however, this can be prevented.
